CPU Comparison
Intel Core i3-9100F vs Intel Core i3-9350K
A side-by-side comparison of specs, performance and value. The Intel Core i3-9100F is a 4-core, 4-thread desktop processor with disabled integrated graphics, launching at $122 to provide pure CPU performance for budget gaming builds where a discrete GPU is present.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Acceptable for single-task office work, but heavy browser multitasking will saturate the 4 threads quickly.
The fast cache and high clocks make single-app use feel snappy, but multitasking is heavily bottlenecked.
Gaming
Can handle older esports titles well, but modern AAA games will stutter due to the 4-thread limitation.
The high clocks help in CPU-bound esports, but the 4-thread limit causes severe 1% low drops in modern games.
Virtualization
4 threads are insufficient to run a modern OS and a useful virtual machine simultaneously.
4 threads are completely inadequate for modern virtualization.
Efficiency
The 14nm process draws more power than modern alternatives for the level of performance delivered.
The 91 W TDP on a 14nm 4-core chip results in very poor performance-per-watt.

Our Verdict on Each
The i3-9100F offered decent single-core speed for its price in 2019, but the lack of Hyper-Threading made it age poorly compared to AMD's 6-core/12-thread alternatives.
Best for: You should only consider the i3-9100F today if you are repairing an existing LGA 1151 gaming PC and can find the chip for under $20 on the used market. It can serve as a stopgap to keep an older system running esports titles. If you are building a new PC, even the cheapest modern alternatives like the i3-12100F will completely obliterate it in performance. Do not buy this new.
Read the full reviewThe 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.
