AMD Announces Ryzen 7 5800X3D With 3D V-Cache

AMD officially announced a new Ryzen 7 5800X3D processor at their CES 2022 livestream. This processor is said to beat Intel’s Core i9-12900K in gaming performance. It has some interesting naming, but it is not some highly-binned Ryzen 7 5800X with a crazy overclock or anything like that. It actually has lower clock speeds! It is AMD’s first consumer chip to make use of their new cache stacking technology, 3D Vertical Cache (V-Cache).

The implementation is 64 MB of fast SRAM physically stacked on top of the CPU core die (CCD), which gives it 96 MB of last-level cache. AMD first introduced this tech with its EPYC “Milan-X” enterprise processors and the Ryzen 7 5800X3D will be the first consumer product to make use of this tech. AMD has thinned out the Zen 3 CCD and V-Cache so they have the same Z-height as the current Zen 3 processors. With the V-Cache sitting on top of the CCD L3 cache it does not impact the heat output of the core and has minimal power up ticks.

When it comes to specifications the Ryzen 7 5800X3D is an 8 core, 16-thread part with a base clock of 3.4 GHz and a boost clock of 4.5 GHz, which is a decrease over the 4.7 GHz of the original Ryzen 7 5800X. It will retain the same 105W TDP as well.

AMD claiming anywhere between 10 to 40 percent gaming performance gains over the Ryzen 9 5900X despite four fewer cores. The chip is a socket AM4 part meaning that you can slot it in to any 500 or 400-series motherboards with a BIOS update. Expected to launch this Spring the price of the Ryzen 7 5800X3D is currently unknown.
