Intel Core Ultra 9 285
A power-capped version of Intel's Arrow Lake-S flagship: the same 24 cores (8P+16E) as the Core Ultra 9 285K, run at a 65 W base power instead of 125 W, with a locked multiplier and the onboard Intel Graphics kept intact. Aimed at quieter or OEM-style builds rather than overclocked desktops.
Pros
- 24 cores (8 Performance + 16 Efficiency) with a 5.6 GHz peak boost, just 0.1 GHz behind the unlocked 285K
- 65 W base power is roughly half the 285K's 125 W, easing cooling and case-airflow demands
- Keeps integrated Intel Graphics, so it can drive a display even without a discrete card installed
- 36 MB L3 and 40 MB L2 cache match the flagship 285K exactly
- DDR5-6400 support with ECC memory compatibility and PCIe 5.0 across 24 CPU lanes
Cons
- Locked multiplier means no manual overclocking headroom, unlike the 285K
- Maximum turbo power still reaches 182 W, so the 65 W base rating understates real cooling needs under sustained load
- Needs a new LGA1851 motherboard, with no upgrade path from older Intel platforms
- No Hyper-Threading, so its 24 threads come from 24 physical cores rather than SMT-doubled cores
