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]

MORE DETAILS

The Intel Core i3-7350K is Intel’s first unlocked i3 processor. The base clock of 4.2 GHz on the 7350K is matched only by the flagship i7-7700K. Consequently for desktop applications and the vast majority of tasks that rely primarily on single core performance the 7350K excels. The i3-7350K’s key feature is an unlocked multiplier which should allow a comfortable overclock (on air) to 4.8 GHz. This makes the 7350K far better suited to desktop workloads than any other non-K CPU. The Achilles heel of only having two physical cores means that for tasks that can use more than two cores such as video encoding or software development, the 7350K lags behind its quad core counterparts. For typical desktop computing such as email, browsing with multiple tabs, office documents and playing the majority of games the i3-7350K is a viable option, but at current prices it’s bested by both the i5-7600K and i7-7700K which offer far better value for money. [Jan '17 CPUPro]
