Intel Core i5-10400F
Intel's 10th-generation Comet Lake i5 drops the integrated GPU of the standard 10400 to cut cost, pairing six cores and twelve threads with a 65 W envelope on the LGA1200 socket. It remains a budget pick for a gaming PC built around a discrete graphics card, though the locked multiplier and DDR4-2666 ceiling limit how far it can be pushed.
Pros
- Six cores and twelve threads for the price of a quad-core chip at launch
- Low 65 W TDP that fits inexpensive H410/B460 motherboards
- Comet Lake core design keeps single-thread performance competitive with pricier chips of its generation in review testing
- Dual-channel DDR4-2666 support keeps platform memory costs low
Cons
- No integrated graphics, so a discrete GPU is required to get a display signal
- Locked multiplier rules out any CPU overclocking
- LGA1200 is a discontinued socket with no upgrade path past 10th/11th-gen Core
- 12 MB of L3 cache and the 14 nm process trail newer budget six-core chips in multi-threaded work
