Intel Core iT vs Intel Core iK

Intel Core iT

&#; remove from comparison

The Intel Core iT is a high end power efficient desktop processor based on the Coffee Lake architecture. Compared to the similar named top model Core iK, the T offers lower clock speeds ( - GHz versus - 5 GHz) and a reduced TDP of 35 versus 95 Watt. It still offers all 8 cores and 16 threads and is intended for small chassis or laptops.

The performance is clearly behind the Core iK and more in the realm of the older 6-core Coffee Lake CPUs.

The integrated Intel UHD Graphics graphics card is clocked at up to GHz and offers no advantage compared to previous generations. As it is a very low end GPU, only some low demanding games like Hearthstone can be played with it (see GPU page for benchmarks).

Intel Core iK

&#; remove from comparison

The Intel Core iK is a high end desktop processor based on the Coffee Lake architecture. At the time of announcement in late , the K is the fastest Coffee Lake CPU and offers an open multiplicator for easy overclocking. The CPU integrates 8 cores (16 threads) clocked at - 5 GHz and it needs a new Z based mainboard.

Thanks to the two additional cores, the performance in multi-threaded applications is up to 25 % faster than the older Core iK. The single thread performance is only slightly faster due to the higher clock speeds. As a high end desktop CPU, the iK is suited even for very demanding applications and perfect for 3D gaming.

The integrated Intel UHD Graphics graphics card is clocked at up to GHz and offers no advantage compared to previous generations. As it is a very low end GPU, only some low demanding games like Hearthstone can be played with it (see GPU page for benchmarks).

Intel specifies the TDP at 95 Watt, so if the CPU is used in laptops a big and chunky cooling system is needed to avoid throttling and lower clock speeds under sustained loads. When overclocking the CPU, the power consumption can easily rise up to Watt and higher.

AMD Ryzen 9 X vs. Intel Core iK

The period between late and early was an inflection point in the ongoing battle between AMD and Intel. In late , Intel continued its dominance in the gaming space by releasing the iK, which was the first CPU outside of Intel&#;s Extreme range to sport the i9 marker. AMD followed up shortly after with the Ryzen 9 X. Although AMD had been competitive in productivity apps in its two previous Ryzen generations, the X proved that team red still has the power to go up against Intel.

The X marks a return for AMD, but that doesn&#;t necessarily mean it&#;s better than the K. Let&#;s dig into the details to find the better CPU.

By the numbers

AMD Ryzen 9 x

Only eclipsed by its core sibling, the Ryzen 9 X is an extremely powerful mainstream CPU packing fantastic specifications. The Core iK is no slouch, however, and by the numbers, they&#;re pretty comparable.

Intel Core i9 KAMD Ryzen 9 X
Process node14nm7nm

Base clock speedGHzGHz
Boost clock speedGHz (all cores)
5GHz (one core)
GHz+ (all cores)
GHz (one core)
GraphicsIntel UHD Graphics No

The X has more cores and threads, while Intel&#;s chip has the stronger clock speed, especially when it comes to single-threaded workloads. Most games now use a handful of cores, so unless you&#;re overclocking, you won&#;t typically see 5GHz frequencies when gaming on a K.

The X can boost to GHz on a single core, but will be closer to GHz if using all cores and threads at the same time. AMD&#;s automated overclocking can take it up to GHz in some cases, though it&#;s very much dependent on your motherboard, BIOS revision, and cooling.

The X has seen a major increase in instructions per clock over its second-generation predecessors, so it&#;s more powerful than the K clock for clock. Its huge L2 and L3 cache effectively eliminate the memory latency concerns from the 2nd-generation chips, too.


Intel Core i9- K

Intel has held a performance edge in gaming for more than a decade, and even with AMD&#;s fantastic first- and second-generation Ryzen CPUs, that held true. But no longer.

In our gaming tests with Fortnite, Civilization VI, and Assassin&#;s Creed Odyssey, the X beat out the K &#; a CPU previously hailed as the best gaming chip ever made &#; on almost all settings, showing a slight lead. That might not be the crushing numbers that AMD fans hoped for, but this is the first time in more than 10 years that a high-end AMD CPU beat the Intel competition in gaming.

The X showed a decent lead in 3DMark, while in Assassin&#;s Creed Odyssey, it matched the K on high settings and exceed it on low settings. In Fortnite, the K shot ahead of the X with high settings, but with over fps in all of our tests, that difference hardly matters.

We saw the most drastic difference in Civilization VI. Across high and low settings, the X beat the K. Most grand strategy games stress the CPU more than the GPU, as the processor handles A.I.-driven opponents and multiple interconnected systems. As with Fortnite, both processors delivered above fps across our trials. AMD&#;s edge in both tests &#; not in a single test, as was the case with Fortnite &#; shows its capability as a gaming CPU.

Price is an important factor, though. Although the K was more expensive than the X at launch, it&#;s cheaper now (a new position for Intel). You can commonly find a K for around $ The X is closer to its launch price, selling for around $

That&#;s if you can find one in stock. The X is back-ordered at most retailers as of March The XT may be more readily available depending on where you shop, and it&#;s almost identical to the X. The XT variant is clocked MHz faster out of the box, but that&#;s the only difference. AMD replaced the X with the X in The X is still available, though we expect AMD to start phasing it out soon.

The K is almost two generations old, with Intel gearing up to launch the its 11th-gen Rocket Lake processors. Given the massive price cut, we expect Intel has already shipped its remaining stock to retailers. If you want a K new, it&#;s best to pick one up now.

It is important to consider the ongoing problems Intel faces with CPU performance hindered by Spectre mitigation, too. Those may continue as new bugs are found in the future, whereas AMD&#;s chips are typically more robust against these kinds of exploits.


Heavily multithreaded productivity tasks like video transcoding and editing have been more AMD&#;s wheelhouse for the past couple of years, with its Ryzen and Threadripper chips competing directly and even pulling ahead of Intel&#;s more expensive options. With the series, and specifically the core, thread X, AMD has beaten not only Intel&#;s mainstream chips (the K included) but will even put some of its older Threadripper cousins out to pasture.

At E3 , AMD provided statistics of its X pitted against one that&#;s more than twice the price: The core, thread, $1, Intel Core iX. And it still cleaned up.

When we received the X for testing, we pitted it against its true rival: The K. Unsurprisingly, the new AMD CPU proved dominant once again.

In Geekbench and Cinebench, the X decimated the K in multithreaded performance, though its reduced clock speed meant it fell just shy of the Intel competition in single-threaded tasks. In the real world Handbrake 4K transcoding test, the X proved almost 25% faster than the K &#; a sizable advantage delivered by the extra cores/threads of the AMD chip.


Efficiency isn&#;t as important on desktop chips as it is with laptops, as there&#;s no battery life to consider. But heat is an important factor, and the more power a CPU requires, the more heat it outputs. That&#;s where the somewhat marketing-driven TDP figure comes from.

By the numbers, Intel&#;s K is the more efficient chip, with a rated TDP of 95 watts, while the X has a TDP of watts. But that&#;s not the full story. Intel&#;s TDP ratings tend to relate to its base clock rather than its sustained boost. AMD&#;s are much closer to the power it pulls when at its highest clock speeds.

Research into power demands from Intel&#;s K around its launch showed it drawing far more power than its TDP rating. Tom&#;s Hardware reported that while it remained under its TDP during gaming, it could require more than watts when doing heavily multithreaded workloads over prolonged periods. That number could increase to watts if overlocked.

We didn&#;t test the X&#;s power draw, but other reviewers have, and Anandtech found it never pulled more than watts when fully loaded. That makes it a more efficient chip than the K too. And that&#;s AMD&#;s big selling point with its Zen architecture: More performance per watt.

The X is the new CPU king

AMD Ryzen 9 x

We were excited for the X before it launched based on prerelease numbers and speculation. Now we can report that after tests, we’re even happier.

In our tests, we found the X rivals the K performance in most gaming and limited-thread tasks, even though Intel has long held the top spot in the gaming world. However, when it came to multithreaded workloads, the X outperformed the competition. Another benefit: Users will be able to use a smaller cooler on their overall setup because the X’s TDP is lower. 

This is a major accomplishment by AMD; the X is an excellent mainstream CPU. We haven’t seen performance levels like this from AMD since their Athlon This success has pushed Intel to play a defensive role &#; it has lowered prices and has a new generation of even-faster CPUs to combat AMD’s best.

Between the two, the X is a clear winner. That said, both processors are dated at this point. Intel&#;s more recent K is much better than the K, and the upcoming K should blow the X away. Similarly, AMD&#;s recent Ryzen chips perform much better than their predecessors.

AMD Ryzen 9 X vs Intel Core iK: Which CPU Is Better?

With AMD’s recent release of the new Zen 2 architecture and Ryzen series processors, the CPU landscape has seen a paradigm shift. In the past, Intel took the performance crown with a higher price point, while AMD was typically the value proposition and behind in overall performance. But AMD has caught up and, in many respects, surpassed Intel on performance, while retaining the price advantage per core and thread. Given that, which high-end CPU to choose may seem like an easy choice, but in reality, things are a bit more complicated.

We’ll put AMD’s new core Ryzen 9 X (the company’s current flagship, at least until the core Ryzen 9 X arrives in September) up against Intel’s top mainstream part, the Core iK in a number of categories below, to help you decide which one is right for your high-end computing needs. If you're looking for a broader selection of chip comparisons, you can also head to our CPU Benchmark Hierarchy.

We’ll take a look at high-level features, available motherboards, overclocking, power consumption, gaming performance, productivity and value to determine which is the better CPU. But while these battles will certainly shed some light on the situation, in the end the right answer for you will depend on your desires and what, exactly, you’ll be doing with your new processor.


AMD’s Ryzen 9 X is a core thread processor with a GHz base clock and the ability to turbo (AMD calls it Precision Boost 2) up to GHz, while slotting into a W TDP. The CPU is technically the second processor in the product stack, behind the previously-mentioned X. Both CPUs blur the lines between mainstream and HEDT systems, as the Intel i9 did previously. The new CPU 7nm architecture (manufactured by TSMC), down from 12nm Zen+ and 14nm Zen on previous Ryzen chips, is part of what provides the notable improvements with AMD’s new CPUs.

In addition to the process node shrink, Zen 2 improves upon memory speed support, raising its base spec to DDR from the previous version’s support of DDR (Zen+/Ryzen ) and DDR (Zen/ original Ryzen). Where Zen and Zen+ were a bit more limited in speed, we’ve seen support on X motherboards reaching into the DDR range. Reaching these speeds is not a guarantee, however, and relies on a good integrated memory controller (IMC), motherboard, and a compatible memory kit. Under sub-ambient cooling we have seen memory paired with Ryzen CPUs reach DDR4 +, in fact. AMD recommends a more realistic speed of DDR4 , though.

One of the other changes with Zen 2 and the X chipset is the implementation of PCIe The new Zen 2 CPUs and Xbased motherboards’ upgrade from PCIe (the speed of both AMD’s previous-gen motherboard chipsets, as well as all current Intel boards) doubles the bandwidth from 32 GBps to 64 GBps. This change can help with storage and content creation, but at the moment it has no perceivable impact on gaming performance, as bandwidth isn’t currently saturated with today’s graphics cards.

The Intel Core iK processor jumps into the ring at a 50% core count disadvantage bringing its eight-core, thread capabilities up against the similarly-priced X. Clock speeds on the iK start off a bit lower with a base speed of GHz (vs. GHz), but Intel’s turbo functionality brings it to GHz for two cores, which are well past AMD’s peak turbo spec. Single-threaded application performance will generally side with Intel when it’s allowed to boost fully, due to the higher clock speeds.

Base memory support on the Coffee Lake-based CPUs is DDR, which is much lower than Zen 2 base spec. That said, Intel-based systems (with compatible boards) are able to generally reach memory speeds approaching MHz (or more with good IMC/board/memory). With similar speeds reachable with the Ryzen 9 X and an X board, memory support specifically is closer to a tie than it seems.

AMD also offers its capable Ryzen Master software, which allows for fine-grained control of the processor. You also get free access to its Precision Boost Overdrive feature, which uses sophisticated real-time algorithms to dynamically overclock your processor based upon chip quality, your cooling solution, motherboard capabilities, and power supply’s ability to feed the motherboard. That wrings the utmost in performance out of the chip, and all with one click of the button.

Intel also recently unveiled its Performance Maximizer software, which automatically overclocks your processor (9th-Gen K-Series models only), but in comparison, it is far less sophisticated than AMD’s Precision Boost Overdrive. While AMD’s implementation is dynamic and can react to different types of workloads and environmental conditions on the fly, Intel’s software sets a static profile that dictates performance regardless of changes to your system. It also only applies to Intel’s priciest chips, while AMD’s suite comes with every SKU.

AMD also ships all of its processors with a bundled cooler, while Intel doesn’t provide a cooler with it’s pricey K-series chips. In the case of the Ryzen 9 X, you get a Wraith Prism RGB cooler (yes, it comes with RGB bling) that can more than sufficiently handle the chips heat output at stock, and even grants some limited overclocking headroom, too.

Winner: AMD

With IPC performance being similar, AMD rules the roost here with a higher core count, better power efficiency at stock, a faster base memory spec, as well as bringing PCIe While the latter doesn’t matter much (if anything) performance-wise for gaming, new PCIe M.2 drives will offer much-faster sequential speeds. AMD’s 12 cores and 24 threads for a similar price as Intel’s 8/16 offering is certainly compelling for buyers who can utilize that much parallel compute.

Motherboard Options

With Zen 2’s release, AMD brought forth a new chipset in X, allowing users access to PCIe , as well as a generally more robust power delivery capable of driving the entire lineup, including the yet-to-be-released flagship core, thread Ryzen 9 X.

Pricing on the X boards ranges from around $ to over $, which on the high end is a notable increase over X flagships. Overall, X motherboard pricing has gone up mainly due to the more robust VRMs as well as the PCIe re-drivers and other bits that enable PCIe support. It is particularly impressive that AMD, once known as being the value alternative to Intel, is now leading the industry by blazing a path to the ultra-speedy PCIe interface.

Features wise, the X boards also include native USB Gen2 (10 Gbps) support and more capable power delivery designed to better support the new chips, particularly while overclocking.

X aside, one of the selling points of the new Ryzen CPUs is backward compatibility with previous-generation chipsets. Support goes all the way back to B, in fact. This move allows users who don’t care about PCIe support to save money by using the same motherboard and dropping in a Zen 2-based CPU, or buying a “new” board with an older chipset for much less money.

In total between the five major AIBs (ASRock, Asus, Biostar, Gigabyte and MSI), users currently have thirty X boards to choose from. Each board partner has a full range of boards and feature sets from ITX to E-ATX, and covers a wide gamut of pricing and features.

On the Intel side, while X is brand-new, the Z chipset has been out for nearly a year. With the Z chipset came with native support for Coffee Lake-based CPUs as well as USB Gen2 (10 Gbps) support, Wireless-AC 2x2 MHz WiFi, and uses the PCIe specification.

Most Z boards are capable of driving the iK--at least at stock settings.

Between the same five board partners, there are 58 boards to choose from just on Z This does not include Z or the lesser chipsets in B and H (which can’t be used for CPU overclocking).

Winner: Intel

Both CPU companies’ latest motherboards offer similar feature sets, including overclocking and native USB Gen 2 support. Though X has PCIe , this doesn’t matter at this time for gaming, though it does allow for faster storage. Pricing, on average, is going to be higher for the X chipsets boards. As time goes on, prices will likely go down on that front, and we expect to see more X board models hit the market as well. The nod goes to Intel for now due to an overall cheaper price range and higher overclocking potential, along with partial integration of Wireless-AC, something that isn’t part of X

Overclocking Potential

Both the AMD and Intel CPUs support overclocking, though how each company handles that in the product stack are different. On one hand, all AMD Ryzen processors are unlocked from the factory, while Intel limits overclocking to the more expensive K-variants and “Z” chipsets. AMD on the other hand allows overclocking a bit further down the product stack to its B chipset.

Intel over the last couple of generations has been able to reach a higher peak overclock when using ambient cooling methods (sub-ambient as well). The iK peaks somewhere around the GHz mark with adequate cooling using all cores and threads. This amounts to a - GHz overclock from the base frequency. Some samples can reach another MHz above 5 GHz, but that’s not as common. Reaching that high may require delidding to keep the temperatures under control, even though the CPU uses solder thermal interface material (sTIM) between the die and IHS.

Since Ryzen hit the scene, the 7nm process itself seems to get in the way of high clock speeds, placing what feels like a hard ceiling on ambient overclocks. Though new, from what we have seen in our review as well as others on the web, the Ryzen 9 X tops out around GHz (Give or take MHz) when manually overclocking all cores. From base clock to fully overclocked, that is a mere MHz increase. AMD seems to push these CPUs about as far as they can go out of the box with its built-in Precision Boost overclocking.

The Intel CPUs tend to yield a more significant performance increase in most tasks, where overclocking a Ryzen CPU doesn’t offer a whole lot in the way of noticeable performance gains due to the Precision Boost technology already pushing the CPU to its performance limits (assuming you have a capable motherboard and cooler) at stock.

Winner: Intel

The Intel CPUs reach a much higher peak overclock speed as well as gaining more performance in the process. The iK wins this round, hands down, with easily better overclocking potential.

Gaming Performance

For many, how a CPU performs in games has long been a measure for how a CPU performs, period. In the past, AMD CPUs were always lagging behind at p at times (and in specific games) by a significant margin. With the release of Zen 2 and its increased cache size, which AMD markets as “gaming cache,” AMD tried to close that gap, and was quite successful in doing so.

The X, when allowed to stretch its legs with Precision Boost Overdrive (PBO), significantly outperforms the previous-generation Ryzen 7 X, and in many cases is just a few to several frames per second (fps) behind the iK. This change yields an average of % performance difference between the two CPUs in our testing.

Intel has been the leader in gaming performance for decades. Team blue’s IPC (instructions per cycle) and higher speeds have typically yielded superior performance over the AMD CPUs. And for the most part, that hasn’t changed, though Intel’s lead has shrunk significantly.

When the iK is manually overclocked to 5 GHz, that lead increases to an average of % across all our tested titles. As it stands, many games simply cannot utilize the extra cores and threads the X has to offer and rely more on clock speeds and IPC performance. In time that may change, but for now higher clocks still rule the p gaming world. But as we’ve said many times before, once you step above that resolution, gaming performance tends to even out as the graphics card becomes the bottleneck.

Winner: Intel

AMD has most certainly narrowed the gap in p gaming performance with Zen 2 when running the CPU at stock speeds, and the company is even able to perform better than the ik in a few CPU-heavy titles. But in the end, Intel’s i9 CPU allows high-end GPU’s to stretch their legs the most. While the difference at stock speeds isn’t noticeable for many, those who are running high-refresh monitors and looking to extract every frame possible out of their system will want to use the K, especially when overclocked.

Productivity Performance

On the productivity side of things, AMD and the X really show their strengths. From web to MS Office, the x beats even the 5 GHz iK in much of our testing. Only in the video conferencing, photo editing, and spreadsheet work does the Intel CPU take the lead.

Outside of that and application startup (where clocks and IPC rule) anywhere the X can make use of its extra cores and threads, it performs better. This includes Corona, Blender, Luxmark, and Cinebench (multi-thread).

The AMD processor also handles encoding duties quite well. We saw it easily beating out the Intel offerings in 7Zip, Handbrake, VeraCrypt AES, and Geekbench. Intel and the Core iK do make a solid showing and flex its per-core performance advantage, though, in single-thread Geekbench, Cinebench R15, and Y-Cruncher.

Winner: AMD

Without a doubt, anywhere the Ryzen 9 X can use its cores and threads fully, it’s the better productivity based CPU. If the applications used are not heavily threaded, the iK shows off its prowess. As time goes on we should see an increase in core use by software, so the AMD CPU should have a longer lifespan in particular with multi-threaded applications.

Since they were sideways to us, it was clearly visible how the guy's penis, shiny with lubrication, either plunges to its. Full length, then reappears from the girlfriend's pussy. We stood in front of them a few steps away, rooted to the spot, watching the action. They did not immediately notice us, completely indulging in their feelings.

They had towels on their hips, bottles of gel in their hands, sparkles in their eyes, a smile on their lips, drops. Of clear, fresh water on their bodies. Widely, openly, in Gagarin style.
