Conclusion 
Average Bench 84.2%

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 AMD 7000X3D CPUs have the same core architecture as the rest of the 7000 series but they have one group of eight "3D" cores with extra cache. The “3D” cores are priced higher but run at 10% lower clocks. For most real-world tasks performance is comparable to the 7000X variant. Cache sensitive scenarios such as low res. canned game benchmarks with an RTX 4090 ($2,000) benefit at the cost of everything else. Be wary of sponsored reviews with cherry picked games that showcase the wins, ignore frame drops and gloss over the losses. Also watch out for AMD’s army of Neanderthal social media accounts on reddit, forums and youtube, they will be singing their own praises as usual. AMD continue to develop “Advanced Marketing” relationships with select youtubers with the obvious aim of compensating for second tier products with first tier marketing. PC gamers considering a 7000X3D CPU need to work on their critical thinking skills: Influencers are paid handsomely to promote overpriced niche products (X3D, EPYC, Threadripper etc.). Rational gamers have little reason to look further than the $300 13600K which offers comparable real-world gaming and better desktop performance at a fraction of the price. Workstation users (and RTX 4080+ gamers) may find value in higher core CPUs such as the 16-core $400 13700K. Despite offering better performance at lower prices, as long as Intel continues to sample and sponsor marketers that are mostly funded by AMD, they will struggle to win market share. [Mar '23 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.
