Our verdict

A cache-heavy eight-core processor for existing AM4 gaming builds. The listing shows no cooler, so plan to buy one separately.

Overview

A desktop build on an older AM4 motherboard is where this chip belongs, using a large stacked cache to speed up game data access. It seats in the Socket AM4 slot of a compatible board.

The reason to look at it is the large cache on a mature, familiar platform, which suits an upgrade without a new board or memory. The limit is the platform itself: AM4 means no move to newer memory standards.

Who it's for

Existing AM4 systems gain the most, since memory and board stay as they are. New builds, buyers on other sockets and anyone expecting cooling hardware bundled should look at other options.

Pros and cons

Pros

Large cache for games
Drops into existing AM4 boards
Eight cores listed
Three year warranty

Cons

Needs an AM4 board with chip support
Cooler not listed
Thread count differs between title and specs
Integrated graphics not listed

Performance notes

Game speed depends on how much data the large stacked cache can hold close to the cores, which helps titles that hit memory often. Tasks that rely mostly on raw clock speed gain less from extra cache.
