AMD is reaping the rewards for reissuing its fastest Socket AM4 gaming CPU, as the Ryzen 7 5800X3D has already hit the Amazon best seller’s chart at number four. The rereleased 5800X3D may have a high price of $349, but that doesn’t seem to have dented its popularity.
With RAM prices at crisis point, many gamers with AM4 motherboards would clearly much rather buy a 5800X3D and use their old RAM than fork out for a new AM5 motherboard and CPU, as well as an expensive DDR5 kit.
To put that chart position into perspective, this four-year-old processor is now outselling its successor, the Ryzen 7 7800X3D, as well as the 16-core Ryzen 9 9950X3D and AMD’s latest 8-core blockbuster, the 9850X3D, on Amazon in the US. There’s clearly a market for AMD’s AM5 CPUs, but gamers are still clamouring for AM4 chips that work with their existing memory.
The AMD Ryzen 7 5800X3D was AMD’s first desktop CPU with the company’s 3D V-Cache tech, adding a whole chip full of 64MB L3 cache on top of its 8-core chiplet. While the 5800X3D doesn’t have a particularly high clock speed, boosting to just 4.5GHz, that extra cache makes a substantial difference to gaming performance. Put simply, it massively reduces the risk of a cache miss and the need to page your slower system memory, which bolsters frame rates.
After going the way of the dodo in 2024, many people, including us, asked AMD to resurrect the 5800X3D in the wake of exorbitant RAM prices. AMD listened and relaunched the chip at Computex 2026, propelling it straight onto our guide to buying the best DDR4 CPU. It wasn’t straightforward, though, with AMD telling us that the chip needed to be entirely re-engineered for fabrication at TSMC.
AMD also attached a high $349 price tag to this four-year-old chip on rerelease, putting it in the same price bracket as the newer 7800X3D, but people are still clearly lapping it up. You don’t need to buy DDR5 RAM to run a 5800X3D, after all, and that’s the key here.
In fact, there are only three more popular CPUs on Amazon US right now, and the number one seller is another AM4 chip, the stripped-down Ryzen 5 5500 (as used in the AWD-IT Kalona). With just 16MB of L3 cache, six Zen 3 cores, and a meagre 4.2GHz boost clock, this isn’t a record-breaking gaming chip. However, with its price of just $81, it’s proving to be incredibly popular, not least because, like the 5800X3D, it will work in practically any AM4 motherboard from the last ten years, and it doesn’t need DDR5 memory either.
There are several other AM4 CPUs in the Amazon top 15 as well, including the Ryzen 7 5800XT and 5700X, as well as the 12-core Ryzen 9 5900XT. AMD is dominating the competition here as well, with the first Intel CPU in the chart being the Core Ultra 7 270K Plus at number 15.
Now that AMD’s 5800X3D re-engineering has proved to be worthwhile, we wouldn’t be surprised if the company released more AM4 CPUs with 3D V-Cache while we ride out the RAM crisis. Chips that don’t quite make the grade could make for a relaunched 5700X3D and, who knows, maybe a few golden samples could end up being used in a higher-clocked Ryzen 7 5850X3D.
