Key strengths
96 MB of L3 cache thanks to AMD 3D V-Cache, three times the 5800X's 32 MB, with 8 Zen 3 cores, 16 threads and up to 4.5 GHz boost.
Supports up to 128 GB of DDR4 with ECC on compatible motherboards, and PCIe 4.0 with 20 usable CPU lanes; the box adds a Carbice Ice Pad.
Before you buy
Has no integrated graphics, so a separate graphics card is required.
Memory speed depends on how many sticks you fit: DDR4-3200 with two, DDR4-2933 with four single-rank and DDR4-2667 with four dual-rank. It also needs an AM4 motherboard with a compatible BIOS.
AMD doesn't list unlocked CPU-multiplier overclocking for this model; its Ryzen Master guide adds memory overclocking only. No cooler is included.
Works with
Products in this catalogue that list the same socket or memory type as the AMD Ryzen 7 5800X3D. A shared socket or memory type is necessary but not sufficient: check the exact CPU and memory support lists, and the BIOS version, before buying.
