Key strengths
96 MB of L3 cache thanks to AMD 3D V-Cache, with 8 Zen 4 cores, 16 threads and up to 5 GHz boost.
Supports EXPO memory profiles, Precision Boost Overdrive and Curve Optimizer, plus PCIe 5.0 with 24 usable lanes and basic Radeon graphics for display output.
Before you buy
No cooler in the box, and AMD recommends liquid cooling for best performance. You also need an AM5 motherboard whose BIOS supports this processor, plus DDR5 memory.
AMD doesn't list unlocked CPU-multiplier overclocking for this model, and memory is rated at DDR5-5200 with two sticks but only DDR5-3600 with four.

Memory support
5 items
- Memory support
- Dual-channel DDR5 UDIMM; up to 128 GB; DDR5-5200 with two DIMMs or DDR5-3600 with four
AMD rates single- and dual-rank DDR5 UDIMMs at the same speeds, with a lower rate for four DIMMs. EXPO is memory overclocking and isn't guaranteed on every motherboard; the board's own capacity limit also applies.
Source - Maximum supported memory
- 128 GB
AMD's CPU limit; the motherboard, its BIOS and the memory kit must also support this capacity.
Source - Memory rate with two DIMMs
- 5200 MT/s
Applies to two single-rank or two dual-rank DDR5 modules. EXPO memory overclocking is separate and depends on the motherboard.
Source - Memory rate with four DIMMs
- 3600 MT/s
Applies to four single-rank or four dual-rank DDR5 modules; slower than the two-module rating.
