The quad core i3-8350K hails from Intel’s most recent (and as yet unreleased) generation of Coffee Lake processors. It has a stock clock of 4.0 GHz, 8MB of cache and a TDP of 95W. The 8350K is the first i3 processor to feature four cores (previous generations of i3s had two cores and four threads). With this eighth generation of processors, Intel has introduced a step change in their nomenclature which witnesses the old quad core i5s become the new quad core i3s. Our benchmarks show a 25% increase in effective speed between generations of i3 8350K vs 7350K and near equivalence between the outgoing i5-7600K and the new i3-8350K. Although the price points of Coffee Lake are not yet known, if Intel keep them roughly in line with the previous generations (i3 ~= $140) this will represent the best improvement in value for money since Sandy Bridge as the 8350K at $140 would be 34.8% cheaper than a 7600K at $215. Cynics among us will see this as an effort to fend off competition from AMD’s new multi-core Ryzen processors. It appears Intel may have been successful with this move as early benchmarks from the 8350K suggest that it beats the more expensive 8 core Ryzen 7 1700 in single and quad core performance by 25%. The 8350K is a great choice for gaming builds, but the budget will also need to factor in a complementary motherboard based on the new 300 series chipset. Expect the quad core i3-8100 which is the 8350K’s little sister featuring a base clock of 3.6 GHz, to follow shortly. [Aug '17 CPUPro]

Don't be fooled by the "i7" name. It performs like a Core 2 Quad with Hyperthreading. Overall performance is fine, but the processor is so insanely power hungry that your power bill will actually take a small hit. Similar to FX processors, it is a glorified space heater with bad IPC. [Apr '20 Viriyena]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate countless reddit accounts. UserBenchmark’s data exposes their marketing spiel so they systematically attack our reputation.
Why don’t large PC brands support UserBenchmark?
PC brands profit greatly from flagship hardware like the 4090, 14900KS, and 7950X3D. We help users get similar real-world performance for less money.
Why don’t any youtubers promote UserBenchmark?
We don't sponsor youtubers, so they have no incentive to praise us. Moreover, brands pay more to market weaker products which puts their youtubers at odds with UserBenchmark.
Why does UserBenchmark have so many negative trustpilot reviews?
Trustpilot hosts user-generated online reviews. It's obvious that the 200+ UserBenchmark reviews, are mostly written by virgin marketing accounts. Real users aren't interested in promoting billon-dollar brands...
Why is UserBenchmark so popular with users?
Instead of pursuing lucrative sponsorships with billion-dollar PC brands, we have dedicated 13 years to publishing accurate real-world data. As a result, our users save millions every year and they return repeatedly.
