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 i5-10400F is a six-core hyperthreaded CPU from Intel’s latest Comet Lake series of desktop processors. This 65 W CPU has single core and all core boost frequencies of 4.3 GHz and 4.0 GHz, respectively. Whilst the 10400F will require a new LGA1200 motherboard, such as the Z490, Intel have guaranteed that the next generation of Rocket Lake CPUs will also be compatible with this chipset. The 10400F is aimed at mid-tier gaming PC builds, and as such, ships with a cooler but without integrated graphics. Despite being officially launched in Q2 of 2020, at the time of writing, the 10400F is still not widely available. Compared to the similarly priced Ryzen 5 3600, the 10400F’s lower memory latency gives it the lead in gaming and effective speed benchmarks. Since the Ryzen architecture creates a gaming bottleneck, it is necessary to upgrade to a higher tier, Intel CPU for better gaming performance. On the other hand comparing the i5-10400F and the i3-10100 shows that the 10100 offers comparable gaming performance for 22% less money whilst also including integrated graphics. [Jun '20 CPUPro]
