The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

MORE DETAILS

AMD’s 7800X3D and 9800X3D CPUs, priced over $400 USD, are widely marketed as “the best gaming CPUs in the world”. This is demonstrated at low resolutions with a 4090-class GPU, whilst conveniently ignoring 0.1% lows (frame drops). Under cherry-picked cache-bound conditions the X3D chips can excel, but there’s a trade-off: the additional cache results in 6% lower boost clocks and 50% to 80% higher prices than their regular counterparts (9700X and 7700X). As with their Radeon GPUs, AMD is looking to drive demand through advanced marketing rather than delivering real-world performance. While Nvidia has effectively countered AMD’s marketing in the GPU space, Intel's marketers remain asleep (terminally?) at the wheel. Nevertheless, the 13600K and 14600K still deliver almost unparalleled real-world gaming performance for around $200 USD. Spending more on a gaming CPU is often pointless, as games are normally limited by the GPU. Without significant improvements in social media marketing: forums, reddit, youtube etc., Intel now face the very real risk of bankruptcy (third worst-performing S&P500 stock from Jan to Aug 2024). Since this summary was published just two days ago, hundreds of twitter threads, thousands of “pcmasterrace” reddit posts, multiple magazine articles, and several youtube videos have emerged in unanimous support for the $480 USD 9800X3D. All of these supposedly disinterested actors are working the weekend to convince you to pay their favourite billion-dollar brand an extra $280 USD this holiday season. [Nov '24 CPUPro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
