Although Sony and Microsoft have already previewed their next-generation consoles, the specific specifications of the PS5 and Xbox Series X remain half-masked. Interestingly, as a joint and chip partner of the two companies, AMD may have accidentally disclosed the performance parameters of both consoles. Eurogamer compiled some of the scattered Ryzen APU test scores on GitHub, speculating that the chips were adopted by the PS5, along with a 3DMark run point for the suspected Xbox Series X.

In April 2019, Oberon reported that the PS5 was using a chip code-named “Gonzalo”. Now we know more about its graphics components (GPU parts), such as Teraflops, memory, bandwidth, and more.
Although details of the CPU components have not been announced in recent revelations, it is known that it has 36 available 2.0GHz cells that provide 9.2 Teraflops GPU computing power for the PS5. (Navi performs much higher than GCN architecture)
The leak also indicates that the PS5 uses gDDR6 memory, the same as the Radeon RX 5700 Series Navi GPU on the PC platform. Rated bandwidth is 448 GB/s, but some tests seem to reach 512 GB/s.
Although not proven, PS5 or supports switchable GPU mode. If calculated on the same 256-bit width, the chip’s GDDR6 memory bandwidth, or from 14Gbps to 16Gbps.
The above specifications, or three “backward-compatible” modes for the PS5, such as the GPU frequency of 2.0 GHz (Gen2 mode), can be used to fully unlock the performance of the PS5 native game.
There are also Gen 1 and Gen0 modes, which can use 36 cells, 911 MHz GPU frequencies, 218 GB/s bandwidth, and 64 grating units (just to the size of the PS4 Pro).
There is little word on the details of Microsoft’s Xbox Series X chip, but Leadbetter managed to get some details from GitHub, suggesting it is expected to have 56 computing units.
Based on the 3584 shaders mentioned in the leak, it can be inferred that Microsoft’s GPU computing target is 12 Teraflops, the memory frequency from 1680 MHz to 1700 MHz, and the bandwidth of AMD’s leaked Arden chip is 560 GB/s.
Finally, as the successors to the PS4 Pro and Xbox One X, the two companies still need to balance performance, cost and selling price. Even if the Xbox Series X is more powerful, it is unlikely to be priced much higher than the PS5.
