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]

The FX-8370 is a top of the range black edition Vishera eight core processor based on AMD’s Piledriver architecture. It was launched in September 2014 and is both cheaper and faster than the FX-8350. The FX range offers high performance and this particular processor holds a world record for reaching an incredible 8.7 GHz when overclocked under lab conditions. For typical users however, the FX-8370 runs at 4.0/4.3 GHz (base/turbo) and typically hits 5.0 GHz when overclocked. Its effective speed is 83 which is currently only exceeded by AMD's 20% more expensive FX-9590 (scoring 85), making it relatively good value for money. Eight cores aren’t necessary for most applications, but things are changing and if you heavily rely on multi-threaded applications then the FX-8370 may be a good choice. [Dec '14 CPUPro]

 Frequently Asked Questions

 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.
