Conclusion 
Average Bench 84.2%
Average Bench 82.1%

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]

The hex-core i5-8500 hails from Intel’s eighth generation of Coffee Lake processors, known for featuring a higher number of cores at each SKU than in previous generations and their refinement of the 14nm architecture as seen in 6th and 7th generation processors. At an estimated price of $184 it offers good multi-core value for money. Its quad core performance nearly rivals the more expensive i7-7700K (the 2017 CPU of choice for many top-end gamers). However based on preliminary benchmarks, the i5-8500 is only marginally faster (2% greater effective speed) than the i5-8400 which is also a recent and competitively priced hex-core Coffee Lake processor. Also, like the i5-8400, the 8500 features 9MB of L3 cache and a frugal TDP of 65W, leaving not much to choose between them. As is the case of all Coffee Lake processors, currently the only motherboards that the 8500 can be paired with feature Intel’s high-end Z370 chipset for overclocking. However, alternative and more suitable 300 series motherboards are long overdue and expected to be available soon. [Mar '18 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.
