Amazon is currently dishing out discount coupons on various AMD Ryzen CPUs in the build up to Black Friday, and we’ve just spotted a great deal on the acclaimed 5800X3D. Right now, you can pick up this cached-up AM4 processor for just $319.99, marking this chip’s lowest ever price since it was rereleased back in June 2026.

“If you have an AM4 motherboard, and you want to squeeze some extra gaming performance out of your system, the 5800X3D remains the best way to do that.” Read our analysis.
If you head over to the Amazon page for this chip, you’ll see it’s already going for $339.95, knocking ten bucks off its standard $349.99 MSRP. However, there’s also a little coupon box, which brings the price right down to $319.99 if you tick it.
Just like all of AMD’s latest X3D CPUs, the 5800X3D has an extra 64MB of L3 cache at its disposal, bringing the total up to a massive 96MB. This has a big impact on gaming performance, as it substantially reduces the chances of a cache miss when your CPU is supplying your GPU with frames, and the need to then page your slower system RAM.
Most importantly, though, unlike the 7800X3D and 9800X3D, you don’t need to fork out for expensive DDR5 memory to run this chip. In fact, if you already have an AM4 motherboard with an AMD Ryzen CPU, even if it’s an old one, there’s a good chance you’ll be able to drop a 5800X3D into it. Just check your motherboard manufacturer’s page for your board, and make sure it has the latest BIOS.
As you can see in the graph above, Far Cry 6 runs substantially quicker on the 5800X3D than on a standard 5800X, or even a 16-core 5950X for that matter. That’s all despite the 5800X3D having a top boost clock speed of 4.5GHz, compared to 4.9GHz on the 5950X – that extra cache really makes a big difference.
Unsurprisingly, the 5800X3D isn’t as fast as AMD’s latest chips, as we found in our 5800X3D vs 9800X3D test recently. It’s based on the older Zen 3 architecture, and uses slower RAM, after all. However, that point is moot if you can’t afford new RAM, and this is a great chip for boosting the gaming performance of an ageing AM4 rig, plus you can use it with your old DDR4 memory.
Certainly, at $319.99, it’s a very tempting upgrade for owners of older systems, and you also get a long-lasting carbon nanotube thermal pad with it. For more buying advice on the latest chips, check out our guide to buying the best CPU for your needs, which includes the 5800X3D.
