The DDR5 memory pricing crisis has sent the whole PC market into utter chaos, including pricing on AMD's flagship AM4 gaming chip. eBay prices for the Ryzen 7 5800X3D have skyrocketed to the point where these chips are being sold regularly for more money than a brand-new Ryzen 7 9800X3D.
Second-hand prices for the 5800X3D average around $500-$600 on eBay. Some of the highest-selling units sold at nearly $800, showing how desperate some buyers are to buy AMD's best gaming chip that still uses DDR4 memory. Average pricing for the Ryzen 7 5800X3D is around $500 right now, which is more money than AMD's latest Ryzen 7 9800X3D. Even AMD's slightly lower-end Ryzen 7 5700X3D is going for $300-$450 on eBay.
For reference, these prices represent almost double what the Ryzen 7 5800X3D used to go for brand new. The chip initially launched at $450 MSRP, but eventually trickled down into the $320 range months later. The absolute lowest price we saw the chip at (brand new) was $269 in August 2023.
Secondhand prices for the 5800X3D have been at or around MSRP for a while, due to the fact that AMD stopped production of the 5800X3D a while ago. However, its most recent price hikes of $500 upwards are new, likely due to the new DRAM pricing crisis forcing buyers back to AM4. AM4 is the only platform that supports DDR4. AMD opted to discontinue DDR4 support completely when creating AM5. Intel is also in a similar boat, having locked itself to DDR5 support exclusively for its latest Core Ultra 200S series chips.
The Ryzen 7 5800X3D took the PC gaming world by storm when it launched in 2022, being the first CPU to take advantage of AMD's 3D-VCache technology. Performance was a generation ahead of other Zen 3 parts, enabling it to outperform Intel's $700+ Core i9-12900KS flagship at the time in gaming performance. Once Zen 4 arrived, the 5800X3D continued to provide value, proving to be an excellent mid-range alternative and outperforming some of AMD's lower-end Ryzen 7000 parts in gaming performance while running on the cheaper AM4 platform with cheaper DDR4 memory.
Buying a 5800X3D for $500 may seem ludicrous, but the aforementioned AM4 support is why the chip is being purchased at these elevated prices. AM4 is still thriving, with plenty of AM4 motherboards still being sold at major retailers for well below $150. Where AM4 is excelling right now is in motherboard and memory combos; at Newegg, you can still find AM4 motherboard + DDR4 memory combos for $150 or less. However, even DDR4 RAM hasn't been immune to price hikes, meaning you still need to shop around for a bargain, unless you already own some, of course.
If you are looking to buy used Ryzen 7 X3D models right now, it's worth checking out the 5700X3D, which is selling at significantly lower prices overall compared to the 5800X3D on eBay. On the flip side, if you own a 5800X3D or 5700X3D, now is the best time to sell it.
