More from this brandAll AMD cpu processorsOverview
Twelve cores, each running two threads, sit on a single package built for the newest AMD desktop socket. The description ties the design to the latest Zen generation, aimed at gamers and creators.
A step up from eight core chips in rendering, streaming and multitasking while still suiting games. Cooling is not described in the listing, and the board and memory must match the newer platform, which makes an upgrade a bigger project.
Who it's for
A builder assembling a new desktop who wants more threads than a mainstream gaming chip. The unlocked multiplier suits tuners. Anyone who only browses and plays light games will not use the extra cores.
Pros and cons
- Twelve cores for mixed workloads
- Unlocked for tuning
- Recent Zen architecture
- Three year warranty
- Needs a matching motherboard
- Cooler not listed
- Higher rated power than eight core parts
Performance notes
Threads help when software spreads work across cores, as video export and rendering do, while many games still lean on the speed of a few cores. The listed power rating sets how much cooling the chip wants under sustained load. Memory and board quality on the platform also affect real results.
