Intel Core i7-10700K vs Intel Core i7-9700K: how does Intel’s 10th Gen chip stack up?

Intel has announced a bevy of new 10th Gen processors at its Comet Lake-S launch, including its new eight-core Intel Core i7-10700K.

It’s likely to be a popular choice among PC gaming enthusiasts, but how does the new chip stack up against 2019’s 9th generation Intel Core i7-9700K? And is there enough of a reason to upgrade to the i7-10700K?

In this article, we’ll put the two processors head-to-head and see if Intel’s 10th Gen chip is worth your hard-earned cash over the Intel Core i7-9700K.

Price and availability

Released in mid-November 2019 for $374 (about £290, AU$530), the Intel Core i7-9700K is still an excellent processor, and we praised its impressive single-thread performance and thermals in our review. 

Thankfully the Intel Core i7-10700K comes in at the same recommended price point as the i7-9700K at $374. We did see some discrepancies for UK pricing during the release of the i7-9700K, however, so we’d be surprised if UK consumers don’t end up paying a slight premium.


So how does Intel’s 10th generation chip differ from its predecessor? Well, both processors come with eight-cores, but the i7-10700K boosts the thread count from eight-threads to sixteen, and supports hyper-threading this time around. 

There’s a noticeable difference in the thermal design power of each chip, too, as the i7-10700K has a TDP of 125W, compared to the i7-9700K’s 95W. The i7-10700K also includes a 20MB cache instead of 12MB.

The Intel Core i7-10700K also has a rated base clock of 3.8GHz compared to 3.6GHz on the Intel Core i7-9700K. Both processors can boost one core using Intel’s Turbo Boost technology, with the i7-10700K reaching up to 5GHz, while the i7-9700K can reach clock speeds of 4.9GHz.

Just like the i7-9700K, the Intel Core i7-10700K is unlocked, and we found that the i7-9700K was an ideal candidate for overclocking as it featured a soldered integrated heat spreader (IHS) instead of the more basic Thermal Interface Material (TIM - aka thermal paste), something which we hadn’t seen since 2nd generation Sandy Bridge Core processors. 

Intel has added its Thin Die STIM to the i7-10700K, which promises improved thermal performance, but the higher TDP may require a beefier cooling solution when the CPU is pushed to its limits.

Intel Core i7-10700K vs Intel Core i7-9700K: should you upgrade?

That’s the big question, and the answer will obviously vary depending on your budget and needs. 

Of course, we won’t be able to provide you with a definitive answer until we’ve put Intel’s new 10th Gen chip through its paces, but it’s clear that the i7-10700K is a pleasing upgrade over the i7-9700K. 

Crucially, if you’re in the market for a new CPU, then you’re getting more power for the same price as last year’s model, which is always a winner.

Next generation

Coffee Lake is Intel's codename for its eighth generation Coremicroprocessor family, announced on September 25, 2017.[5] It is manufactured using Intel's second 14 nm process node refinement.[6] Desktop Coffee Lake processors introduced i5 and i7 CPUs featuring six cores (along with hyper-threading in the case of the latter) and Core i3 CPUs with four cores and no hyperthreading.

On October 8, 2018, Intel announced what it branded its ninth generation of Core processors, the Coffee Lake Refresh family.[7] To avoid running into thermal problems at high clock speeds, Intel soldered the integrated heat spreader (IHS) to the CPU die instead of using thermal paste as on the Coffee Lake processors.[8] The generation was defined by another increase of core counts.

Coffee Lake is used with the 300-series chipset, and officially does not work with the 100- and 200-series chipset motherboards. Although desktop Coffee Lake processors use the same physical LGA 1151 socket as Skylake and Kaby Lake, the pinout is electrically incompatible with these older processors and motherboards.[9]

On April 2, 2018, Intel released additional desktop Core i3, i5, i7, Pentium Gold, Celeron CPUs, the first six-core Core i7 and i9 mobile CPUs, hyper-threaded four-core Core i5 mobile CPUs, and the first Coffee Lake ultra-power CPUs with Intel Iris Plus graphics.

On June 8, 2018, to commemorate the 40th anniversary of the Intel 8086 CPU architecture, Intel released the i7-8086K as a limited edition CPU, a renumbered and slightly higher clocked batch of the i7-8700K dies.


Its development was led by Intel Israel's processor design team in Haifa, Israel, as an optimization of Kaby Lake.[10] Intel first launched its 8th Generation Intel Core family processors in August 2017. While with the release of the new 8th Gen Intel Core i9 processor in 2018, Intel said it would be the highest-performance laptop processor Intel has ever built.[10]


Coffee Lake CPUs are built using the second refinement of Intel's 14 nm process (14 nm++).[6] It features increased transistor gate pitch for a lower current density and higher leakage transistors that allows higher peak power and higher frequency at the expense of die area and idle power.

Coffee Lake marks a shift in the number of cores for Intel's mainstream desktop processors, the first such update for the previous ten-year history of Intel Core CPUs. In the 8th generation, mainstream desktop i7 CPUs feature six cores and 12 threads, i5 CPUs feature six single-threaded cores and i3 CPUs feature four single-threaded cores.

9th generation[edit]

For the 9th generation, the Intel Core i9 branding made its debut on the mainstream desktop, describing CPUs with 8 cores and 16 threads. 9th generation i7s feature 8 single-threaded cores, marking the first time desktop Core i7s have not featured Intel's Hyper-threading technology, although the 9th generation Core i7 mobile CPUs do support hyperthreading and have 6 cores just like 8th gen mobile chips. 9th generation i5 CPUs feature six single-threaded cores, just like their 8th generation predecessors.

The ninth generation Core i series includes hardware fixes for Meltdown V3 and L1 Terminal Fault.[11]


The 300 series chipsets, while using physically identical LGA 1151 socket to the 100 and 200 series chipsets, are officially only compatible with Coffee Lake CPUs, meaning that older motherboards do not officially support Coffee Lake processors,[12][9] and 300 series motherboards do not officially support Skylake or Kaby Lake processors.

The enthusiast Z370 (a rebranded Z270), launched alongside the first Coffee Lake CPUs in October 2017, was the only officially supported chipset for these mainstream CPUs. When the full lineup of CPUs was revealed in April 2018, it was then accompanied by the lower-end H310, B360, H370 and Q370 chipsets for home and business users. The Z390 chipset was launched alongside the release of the 9th generation CPUs, supporting all 8th and 9th generation mainstream desktop parts. A B365 chipset was added later on.

9th generation Xeons require motherboards with the C246 chipset.[13]

Architecture changes compared with Kaby Lake[edit]

Coffee Lake features largely the same CPU core and performance per MHz as Skylake/Kaby Lake.[14][15] Features specific to Coffee Lake include:

  • Increased core count to six cores on Core i5 and 8th generation i7 parts; Core i3 is now a quad-core brand. 9th generation i7 and i9 parts feature eight cores.
  • Increased L3 cache in accordance to the number of threads
  • Increased turbo clock speeds across i5 and i7 CPUs models (increased by up to 400 MHz)
  • Increased iGPU clock speeds by 50 MHz and rebranded it UHD (Ultra High Definition)
  • DDR4 memory support updated for 2666 MHz (for i5, i7 and i9 parts) and 2400 MHz (for i3 parts); DDR3 memory is no longer supported on LGA1151 parts, unless using with H310C chipset
  • 300 series chipset on the second revision of socket LGA 1151
  • Support for CNVi

Kaby Lake Refresh vs. Coffee Lake[edit]

Main article: Kaby Lake § List of Kaby Lake R processors

On August 8, 2017, Intel announced the first of its new eighth generation of processors would be mobile processors.[16] As Intel's previous changes in product generations coincided with new microarchitectures, it was unclear[17] but generally expected that the eighth Core generation products would be based on the new Coffee Lake microarchitecture.[18] When it was officially announced on August 21, 2017, however, Intel stated that the eighth generation family would be based on multiple microarchitectures: Kaby Lake Refresh, Coffee Lake[19] and Cannon Lake.[20]

List of 8th generation Coffee Lake processors[edit]

Desktop processors (Coffee Lake S)[edit]

These processors mark the first time that Intel has released mainstream consumer CPUs that support up to 128GB RAM.[21]

* various reviews show that the Core i7-8700K CPU may consume over 110W under load.[24]

Workstation processors (Coffee Lake S)[edit]

Mobile processors (Coffee Lake H & Coffee Lake U)[edit]

List of 9th generation Coffee Lake processors (Coffee Lake Refresh)[edit]

The first 9th generation Coffee Lake CPUs were released in the fourth quarter of 2018. They include hardware mitigations against certain Meltdown/Spectre vulnerabilities.[25][26]

The main differences from the 8th generation (besides increased frequency) are:

  • Core i7 parts contain 8/8 cores/threads compared to 6/12 in 8th generation Core i7 parts.
  • Core i3 parts are equipped with Turbo Boost technology.

Even though the F suffix CPUs lack an integrated GPU, Intel set the same price for these CPUs as their featureful counterparts.[27] Intel eventually reduced the official pricing of those CPUs in October 2019.[28]

The Intel Core i9-9900KS CPU, released at the end of October 2019, features a limited one year warranty both for box and tray versions due to "its limited volume".[29]

ไขความแตกต่าง ? ของ Intel Core i3, i5, i7 และ i9

Intel's powerful Core i9 family recently displaced Core i7 as the company's mainstream desktop flagship. Mainstream is relative, though. The Intel Core i9-9900K sells for more than $500, requires a high-end cooler, a beefy motherboard, and really needs to be paired with lots of fast memory. It's prohibitively expensive for all but the most affluent enthusiasts.

Core i7-9700K, on the other hand, lands right where we expect to find any other high-end, unlocked, Core i7 CPU. It even boasts a number of improvements compared to the previous generation. Like Intel's Core i9-9900K, the i7-9700K includes eight physical cores. However, it doesn't benefit from Hyper-Threading. That doesn't bother us much. After all, some software performs notably better on physical cores rather than logical ones, and the two-core increase compared to the Intel Core i7-8700K largely offsets the loss of Intel's simultaneous multi-threading technology.

Given the Core i7-9700K's lofty peak frequencies, improved multi-core Turbo Boost ratios, eight-core configuration, and solder-based thermal interface material that improves heat transfer and overclocking, Intel's latest Core i7 is an all-around winner and, at publication time, tops our list of the best gaming CPUs. However, AMD has intervened in the following months, releasing a new lineup of ultra-competitive Ryzen 3000 chips, with the Ryzen 5 3700X taking the helm as the best value-focused chip in this price range. 

Pricing is a bit of a problem, though. The Core i7-9700K sells for $385 if you can find one available at Intel's suggested retail price. Meanwhile the competing AMD Ryzen 7 2700X retails for $329. The Ryzen also comes bundled with a capable cooler, whereas Intel makes you pay for a high-end thermal solution. The Core i7-9700K is faster than Ryzen in games, no doubt. But budget-limited builders might go the Ryzen route in order to afford a faster graphics card. And AMD's CPU still holds the advantage in some threaded application workloads.

For the enthusiasts among us who have some breathing room in their budgets, Core i7-9700K is a much smarter choice for gaming than the pricey Core i9-9900K, serving up similar performance at a significantly lower price.

Intel Core i7-9700K

The $385 Core i7-9700K lands between the $500+ Core i9-9900K and the $263 Core i5-9600K in Intel's line-up. Like all new K-series processors, the -9700K is manufactured on Intel's 14nm++ process. It includes an integrated UHD 630 graphics engine, sports unlocked ratio multipliers for easy overclocking, and supports dual-channel DDR4-2666 memory. Intel also responded to increasing RAM density by doubling memory capacity support up to 128GB. The -9700K also includes in-silicon mitigations for the Meltdown and L1TF (Foreshadow) vulnerabilities.

Previously, Intel's Core i7 series included Hyper-Threading technology, allowing four- and six-core models to execute eight or 12 CPU threads simultaneously. Intel axes Hyper-Threading from the 95W Core i7-9700K, though. The company instead gives you an extra two cores. Assuming a 15-20% uptick from HTT under ideal conditions, we'd hypothesize that an 8C/8T -9700K should be faster than the 6C/12T -8700K in most workloads. Then again, we already have the benchmark results to back our supposition.

The Core i7-9700K includes 12MB of L3 cache, just like Intel's Core i7-8700K. But given a higher core count, that actually adds up to less cache per core than Intel's previous designs. Unfortunately, the company deliberately disabled on-die SRAM to keep Core i7-9700K from coming too close to Core i9-9900K's performance.

Core i7-9700K's solder-based thermal interface material (STIM) improves heat transfer between Intel's die and heat spreader, facilitating headroom for two more cores without violating a 95W envelope at base clock speeds. Intel does cap its Core i7-9700K at a base frequency of 3.6 GHz, which is 100 MHz less than Core i7-8700K's base clock rate. But when you consider that the company enables higher Turbo Boost frequencies across the board, all while adding those extra cores, it's hard not to be impressed.

Just bear in mind that a 95W ceiling doesn't apply to Turbo Boost clock rates. Even in its stock configuration, Core i7-9700K begs for at least a 130W cooler. The eight-core die hides beneath the same heat spreader used on previous-gen six-core models. So, even with the STIM, thermal density presents challenges. If you plan on overclocking, open- or closed-loop liquid cooling is preferred. A beefy heat sink/fan combination won't give you much headroom (though it should be fine for stock operation, unlike Intel's Core i9-9900K).
