Newegg is selling AMD’s rereleased Ryzen 7 5800X3D 10th Anniversary Edition for $349.99 with an MSI MAG Coreliquid 250mm AIO cooler included at no extra charge, according to Tom’s Hardware. For people trying to keep an older AM4 gaming PC alive, that is the point: it avoids a jump to DDR5 memory and a newer platform.
The cooler is listed as a $69.99 add-on, so Tom’s Hardware calculates the effective CPU cost at about $270 if a buyer actually wanted that cooler. That is deal math, not magic, but it does put the package below the processor’s stated $349.99 MSRP on a parts-value basis.
Newegg is also offering a combo built around the same CPU with an Asus TUF Gaming B550-Plus motherboard, 16GB of TeamGroup T-Force Delta DDR4 memory, and the same MSI cooler. Tom’s Hardware’s deal block lists that bundle at $529.99, though its closing summary gives $549.99. The parts-discount figure cited is $103.99 versus buying the bundle items separately, before counting the $69.99 cooler.
What the chip actually is
The Ryzen 7 5800X3D is an eight-core, 16-thread Zen 3 processor for AMD’s AM4 socket. It boosts up to 4.5GHz and carries 96MB of L3 cache, the feature that made the original chip unusually strong in games for its generation.
Tom’s Hardware says its re-review and CPU benchmark data show the 5800X3D remains the fastest option for AM4 systems using DDR4 memory. That claim is narrower than “best gaming CPU,” and the distinction matters. Newer AMD X3D parts such as the Ryzen 7 7800X3D and 9800X3D sit on later platforms and benefit from DDR5 memory, which Tom’s Hardware says can itself lift game performance.
The pitch here is less glamorous: avoid replacing more of the PC than necessary. DDR5 prices have risen in recent months, according to Tom’s Hardware, so an AM4 drop-in upgrade can look less silly than it did when newer platforms were cheaper to build around.
What comes in the bundle
- AMD Ryzen 7 5800X3D 10th Anniversary Edition CPU
- Asus TUF Gaming B550-Plus motherboard
- 16GB TeamGroup T-Force Delta DDR4, sold as two 8GB modules
- DDR4 speed listed at 3,200 MT/s, with customizable RGB lighting
- MSI MAG Coreliquid 250mm AIO cooler, valued at $69.99
Tom’s Hardware reviewed the Asus TUF Gaming B550-Plus line in 2020 and described it as a solid AM4 all-rounder. The board supports Wi-Fi 6, 2.5Gb Ethernet, up to 128GB of DDR4 memory, Type-C and Type-A USB ports, and two M.2 SSDs, one of which supports Gen 4 speeds.
Stock for the 10th Anniversary 5800X3D has moved around since launch, according to Tom’s Hardware, with scalpers previously trying to sell it at about twice the official price. At Newegg’s $349.99 CPU listing, the processor is back at MSRP, with the cooler doing the discounting work.
