Conclusion 
Average Bench 84.2%
Average Bench 86.1%

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]

"Build to perform. Designed to win". Launched 25 November of 2019, this monstrous 32 core 64 thread CPU boasts 88 PCIe 4.0 lanes (16 lanes used for high-speed interconnect, 176 PCIe 3.0 lanes effective), 147MB of cache, 3.7GHz base and 4.5GHz max boost clock with 280W effective TDP. This EHEDT (Extremely High End Desktop) CPU leads well on nearly every benchmark you throw at it (not even on gaming!) and it's performance well exceed the current Intel's flagship i9-10980XE which was released at the same time as this CPU and costs $979 and Xeon W-3175X which is the previous king that costs $2999 and was released at Q2 2019. For all of that benefits you get from this CPU, you had to pay for $1999 which is way beyond reach for most consumers and were intended for serious content creator. [Nov '19 ColdSpy]

 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.
