Does the Ryzen 7 3800XT include a cooler?

No. Unlike the Ryzen 7 3700X, it ships without a stock cooler, so you need your own AM4-compatible cooler.

Do I need a graphics card with this CPU?

Yes. The 3800XT has no integrated graphics, so it needs a discrete GPU to display anything.

It fits AM4 sockets on 400 and 500 series chipsets. A BIOS update may be needed on older boards.

They share 8 cores, 16 threads and 36MB cache. The 3800XT has slightly higher clocks, but the real-world difference is small.

The 3800XT has two more cores for heavy multitasking, but the 5600X is faster in most games and easier to cool.

The processor itself. This is an open-box, unused unit, so confirm included accessories and warranty terms before ordering.
