During its CES 2022 presentation, AMD revealed that it planned to release its Ryzen 7 5800X3D to better combat the excellent gaming performance offered by Intel’s strong 12th Generation CPUs, and the 12900K in particular. Prior to the reveal, we expected AMD would release 3D versions of its 5900X and 5950X processors. AMD did previously demonstrate a 5900X prototype, but according to Digitimes, manufacturing limitations are likely behind the reason we’ll only be seeing the 5800X3D for now. [4]

Figure 1 shows specs show that the system packing the Ryzen 7 5800X3D is in the same system with 16GB of memory and a Radeon RX 6800 XT graphics card. The system runs on Windows 11 Pro but states that virtualization is not supported. The reading is probably an error on Microsoft's part, as most AMD motherboards come with virtualization disabled at the BIOS level, which you can enable manually. The L2 cache is also specified at just 512KB since the software doesn't list the L3 cache for processors. [3]

MD Ryzen 7 5800X3D CPU Specifications

In terms of specifications, the AMD Ryzen 7 5800X3D will offer 8 cores and 16 threads within a single CCD. It will rock a base clock of 3.4 GHz & a boost clock of 4.5 GHz which is slightly slower than the 4.7 GHz of the Non-3D Ryzen 7 5800X. The CPU will feature a TDP of 105W which is the same as the Ryzen 7 5800X.

The main difference between the two chips is the amount of cache. The AMD Ryzen 7 5800X3D will carry 32 MB of L3 cache on-die and 64 MB of cache off-die within the vertical stacks. The CPU will feature a single 3D V-Cache stack that incorporates 64 MB of L3 cache and sits on top of the TSV's already featured on existing Zen 3 CCDs. This will give a total of 96 MB L3 cache directly to the Zen 3 cores.

AMD has thinned out the Zen 3 CCD and the V-Cache so they have the same Z-height as the current Zen 3 processors rather than varying heights between the cores and the IOD. Since the V-Cach sits on top of the CCD L3 cache, it doesn't affect the heat output of the core and has minimal power up-ticks. [1]

• Minor optimization on TSMC’s 7nm process node
• Up to 64 MB of Stacked cache per CCD (96 MB L3 per CCD)
• Up To 15% Average performance improvement in gaming
• Compatible With AM4 Platforms and existing motherboards
