How to read this comparison
Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

What it brings
8 Performance-cores and 16 Efficient-cores (32 threads), up to 6.2 GHz turbo and 36 MB of L3 cache, with DDR5-5600 or DDR4-3200 memory support up to 192 GB.
Unlocked for overclocking with Intel XTU 7.14, plus Quick Sync Video, Thread Director and Intel Application Optimization (APO) support on enabled platforms.
High power limits (150 W base, 253 W maximum turbo) and no cooler in the box, so budget for strong cooling. Intel advises the latest motherboard BIOS with microcode 0x12F or later and Intel Default Settings; this doesn't repair a processor that is already unstable.
16 Zen 3 cores and 32 threads with up to 4.8 GHz boost and 64 MB of L3 cache; supports up to 128 GB of DDR4, ECC on compatible motherboards and unlocked overclocking.
Memory speed depends on how many sticks you fit: DDR4-3200 with two, DDR4-2933 with four single-rank and DDR4-2667 with four dual-rank. It also needs an AM4 motherboard with a compatible BIOS, a separate cooler and a graphics card.
