Conclusion 
Average Bench 81.8%
Average Bench 81.7%

The i5-8400 is a competitively priced hex-core processor from Intel’s 8th generation of Core processors (Coffee Lake). Along with the release of the unlocked i5-8600K, this is the first time that six-core processors have featured in the i5 line-up. Like the other Coffee Lake processors, the i5-8400 is based upon an improved version of Intel’s 14nm architecture which featured in both Skylake and Kaby Lake. Early benchmarks reveal that for average quad core usage (most games employ a maximum of four cores) the i5-8400 performs way above its pay grade. It achieves quad core mixed speeds close to Intel’s outgoing 2017 flagship the $300, quad-core, 8 thread i7-7700k, which to date has been a strong favourite for high-end gaming setups. On paper, the i5-8400 has a base clock of 2.8 GHz (Intel are significantly downplaying the performance of this SKU by giving it a relatively low nominal base clock), an all core boost of 3.8 GHz (this is the effective base clock figure that counts) and a single core boost of 4 GHz. This compares reasonably well to the i5-8600K which has a base clock of 3.6 GHz, all core boost of 4.1 GHz and a single core boost of 4.3 GHz. The i5-8400 also features 9MB of L3 cache and an energy-thrifty TDP of 65W. Priced at under $190, the i5-8400 offers fantastic value for money. Unfortunately, like the other Coffee Lake processors, the i5-8400 will require a new 300 series motherboard, and at the time of writing, the only available version is Intel’s high-end Z370 which isn't an ideal pairing for the i5-8400. The Z series motherboards are designed to cater for the unlocked and overclockable "K" SKUs. Cheaper 300 series motherboards will be available in 2018 at which time the 8400 will offer even better value for money. [Oct '17 CPUPro]

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]

 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.
