Which should you buy?
For gaming this is a wash, so the decision comes down to price, platform and what else you do with the PC. If you stream or render too, the Core Ultra 5 245K's extra threads tip the balance.
Buy the Ryzen 5 9600X if…
- you plan a faster graphics card: it keeps up with GPUs up to the RTX 4090 at 1440p.
- you're building new: AM5 is the platform AMD's current Ryzen CPUs use.
Buy the Core Ultra 5 245K if…
- you also stream, edit video or compile code: 14 cores / 14 threads vs 6 / 12.
- you pair it with a mid-range card: with an RTX 5070 at 1440p the two are level.

These numbers use an RTX 5090 to isolate the processor. Your own graphics card, resolution and settings change the result, so run your exact parts through the calculator.
