Intel Core i3-8350K vs Intel Core i3-9350K

A fun overclocking toy in 2017, but the lack of Hyper-Threading and a high 91W TDP make it a poor value compared to even cheap modern chips.

Best for: You should avoid buying the Intel Core i3-8350K unless you are a dedicated overclocking hobbyist looking for a cheap project chip to practice manual tuning, delidding, or extreme cooling on. If you fall into that niche, buying a used 8350K for $20 and pushing it to 5.0 GHz can be incredibly fun and educational. However, for any practical use case—gaming, work, or productivity—this chip is a poor investment. It requires an expensive Z370 or Z390 motherboard to utilize its only feature (overclocking), yet a locked Ryzen 5 3600 on a cheap B450 board will destroy it in every multi-threaded benchmark while using less power. The lack of Hyper-Threading is a fatal flaw that no amount of frequency can fix. Spend your money on modern hardware.

The i3-9350K is an interesting engineering exercise with its high clocks and large cache, but the lack of Hyper-Threading and 14nm process limitations make it a poor value compared to a slightly more expensive i5.

Best for: The only reason to seek out an i3-9350K today is for a retro overclocking project or if you are a collector of unusual Intel silicon. If you happen to have one, pushing it to 5 GHz on a Z390 board with liquid cooling can be a fun experiment. It should not be purchased for any practical computing task. Even in 2019, spending slightly more on an i5-9400F or i5-9600K was the objectively correct decision for both gaming and productivity.
