More from this brandAll AMD cpu processorsOverview
A 16-core, 32-thread desktop processor for the AM4 platform, built on AMD's Zen 3 architecture with a 4.8GHz max boost and an unlocked multiplier for overclocking.
This chip lets AM4 owners add core count without a full platform change, since it drops into existing Socket AM4 motherboards with PCIe 4.0 support.
- 16 cores, 32 threads, Zen 3 architecture
- 4.8GHz max boost, unlocked
- 72MB cache, DDR4-3200 support
- AM4 socket, PCIe 4.0
Who it's for
Fits builders wanting to extend the life of an AM4 motherboard with a high core count chip for content creation or gaming. Not for anyone building fresh on AM5 or expecting a bundled cooler.
Pros and cons
- 16 cores and 32 threads for multitasking and content creation
- Unlocked multiplier for overclocking
- Drops into existing AM4 motherboards
- No cooler included
- AM4 and DDR4 are not AMD's current platform
Performance notes
Specified with 16 cores and 32 threads, 72MB of cache and DDR4-3200 memory support, plus an unlocked multiplier for overclocking on a compatible motherboard. PCIe 4.0 support carries over from the AM4 platform. No cooler ships with the chip, so the 4.8GHz boost figure assumes adequate third-party cooling.
