Actually, it's the Rocket Lake 11900k with the bigger cache. Sure, 10900k has more total L3 cache, but that's because of the extra 2 cores. Performance wise, that's still the same exact 2MB per core. However, the low level cache L1 is 50% larger on 11900k (96KB per core), and L2 cache is DOUBLE on 11900k (512KB vs 256KB) . In gaming that will translate to better minimums and thus smoother gameplay. And it will perform better in almost all games bc of it's higher single core scores and due to the fact that most games won't utilize the extra 2 cores on 10900k.

aalishine, I recommend an SSD, preferably an NVME SSD. Very strange that you only have an old HDD with those specs.

i will choose intel core i9 10900hk because i plan to buy the laptop asus zenbook pro duo 15 oled ux582 with the 10 th gen. it suppose to be available in april 2021. it will be nice if asus wait for the 11 th gen. probably the first laptop with 11 th gen. will be gaming laptop. i am not interest at all about gaming laptop. one thing thing it certain, i will never buy a apple product.
