  • Whether or not we have to thank AMD for Intel's quick turnaround on the availability of six-core consumer-grade CPUs we will never know for sure. However, it became very clear to us that the Core i7-8700K hits the sweet spot of multi-core performance almo...

  • Early in 2017, Intel released their brand new Kaby Lake platform, featuring a plethora of CPUs and motherboards. The Kaby Lake platform introduced nothing new over what Skylake and its boards already offered. It was simply part of Intel's yearly refresh a...

    With Coffee Lake Intel has a very fast processor series offering available for the masses. You can complain about pricing in comparison to the much cheaper Ryzen 5 1600X (229 EURO) but purely seen from a performance perspective, the Core i7 8700K is absol...

    Good: Great for highend gaming and competent at productivity. Offers better allaround performance than the 7700K. One hell of an overclocker

    Bad: Relatively expensive compared to Ryzen. Expect to spend $550for the chip, a motherboard and a nice cooler

    Intel's new mainstream flagship Core i7 processor is a beast. For gamers seeking the ultimate solution there is simply nothing better than the Core i7-8700K. Out of the box performance is incredible, overclocking is even more incredible, power consumption...

    Good: Strong Multi-Thread Performance, Killer Single-Thread Performance, Relatively Low Power, High Overclocks

    Bad: Requires New Motherboards, Despite Using LGA1151 Socket, Not All Unlocked

    Intel Core i7-8700K And Core i5-8400 Processors -- Find Them At AmazonAlthough they are not based on a totally new architecture, the design choices Intel made with Coffee Lake and its 8th Generation Core processors completely re-shape the company's mainst...

    Good: 50 percent more cores and threads (and higher boost clocks) than previous-gen mainstream chips, Best gaming performance we've seen at 1080p, when paired with a GTX 1080, Consistently tops AMD's similarly priced Ryzen 7 1700X

    Bad: Higher MSRP than Core i7-7700K, Requires a new motherboard, despite Z370 chipset offering no substantive new features

    With high clocks and hexa-core design, Intel's top 8th Generation/"Coffee Lake" desktop CPU impresses as a mainstream "do-it-all" processor. It's an excellent gamer, too, when paired with a high-end video card (though Coffee Lake Core i5s can be a better...

  • It's time to condense all of our test results into our famous value scatter plots. We use a geometric mean of all of our real-world results to ensure that no one test has an undue impact on the overall index. First up, let's look at gaming performance. T...

  • The Intel Core i7-8700K was an exciting processor to benchmark and overclock as Coffee Lake drastically improves performance at a minimal price increase. For $20 more than a 4-core, 8-thread Core i7-7700K Kaby Lake processor you can now get a 6-core, 12-t...

  • With the enormous sales figures that the mainstream Intel processors achieve it is always going to be in everyone's interest when a new model appears.Given the number of cores and performance that we saw when the Ryzen 7 processors appeared there was a si...

  • The performance story surrounding the 8th Generation Intel Core processors codenamed Coffee Lake is straightforward. Take the Kaby Lake parts that were already damned good, increase the core count in Core i7, Core i5, and Core i3 families, and also increa...

  • Intel's 6-core 8th generation Core i7-8700K CPU is the reality check to high-performance, high-priced CPUs like the $2,000 Core i9 and $1,000 AMD Ryzen Threadripper. The real battle for the desktop and consumer's wallets is with this amazingly affordable...

  • 2017 has been an interesting year for processors with AMD's long awaited introduction of the Zen-based Ryzen / Threadripper / EPYC processors, Intel's Core X-Series processors for high-end desktops, the Xeon Scalable processor family introduction, and now...

  • It's hard to know where to start here. Besides the exciting times of finally seeing more than 4 cores on the mainstream desktop platform, all 6 cores come out swinging. Intel's i7-8700K consistently placed at or very near the top of all of our benchmark r...

  • The 8th Generation Intel Core processors, codenamed Coffee Lake, are the first Intel processor family to garner so much interest in recent history. Thanks to the Ryzen Effect, Intel is finally increasing the number of processor cores across the board...

  • Good: 6-core in a mainstream Intel chip, 36% multi-core performance improvement over the i7-7700K, Can easily overclock to 5.0 GHz, Single-core performance improvements, Beats Ryzen in gaming performance, Platform has 40 PCI-Express 3.0 lanes

    Bad: New motherboard needed, Sort of upsetting if you've bought an i7-7700K recently

    As you can see from our results on the previous page this is not an ordinary processor update from Intel. The 8th Generation Core Desktop series is bringing with it increases in core counts finally! We are going to see 6-core i5's and i7's and even quad-c...

  • Good: Strong performance in games and productivity applications, Lower priceperthread than competition, Overclocking headroom

    Bad: Zseries motherboard requirement, Overclocking tax

    Intel finally expanded the core count of its mainstream processors, facilitating solid all-around performance from the Core i7-8700K. Aggressive Turbo Boost bins ensure great performance in lightly-threaded workloads, while six cores cut through deman...

  • Good: The best CPU for gaming, Strong out-of-the-box clock speed, Intel's six-cores beat AMD's eight-cores in many production tasks, Offers substantial gains over Skylake and Kaby Lake in multithreaded apps

    Bad: Still only 16 PCIe lanes on the CPU, Platform needs voltage tweaks to run at its best, Coffee Lake is the third "optimisation" of an existing architecture with no IPC improvement, The 8700K runs very hot and pulls a lot of watts, You can overclock to over...

    For those who game, there's no better processor than Intel's Coffee Lake Core i7-8700K. Where its predecessor, the Kaby Lake Core i7-7700K, offered little more than slightly higher clock speeds and a way to decode DRM-laden 4K video over 2015's 6700K, t...

  • It was just nine months ago when we said the Kaby Lake flagship was the chip we've been waiting for. Now, just three quarters later, Kaby Lake has effectively been wiped off the map. The king is dead. Long live the king!The Intel Core i7-8700K, formerly k...
