Currently, we’ve seen sony and Microsoft both disclose some simple information about the next generation of home games consoles, such as new features on the new console, such as sSDs, new Zen 2 architecture-based CPUs and Navi-based GPUs. But neither of them has yet to disclose the specific parameters of the new generation of consoles, and we can only guess the specific configuration of the new console, especially the specific specifications they have on the graphics card, because that’s the most important thing for the game.
Digital Foundry recently passed on the previous AMD’s mysterious chips, codenamed “Gonzalo,” “Oberon” and “Arden”, and leaked test data on them on GitHub, to the PS5 and Xbox Series The relevant specifications of X have been speculated upon.

The first is the PS5, which Digital Foundry believes is most likely the chip used on the PS5, which was unveiled last April (2019) by the “Gonzalo”,” which has now been changed to the “Oberon”). By interpreting the model, they believe the chip may have been equipped with a GPU code-named “Navi 10 Lite”.
At the same time, tests of recent leaks have tited that the GPU is indeed the Navi 10, but with four less CUs, and that it works at a fairly high frequency – 2.0GHz. At 36CU scale and 2.0GHz operating frequency, the GPU’s single-precision computing power can reach 9.2 TFLOPS, because the RDNA architecture has a relatively large improvement in efficiency, so this 9.2 TFLOPS has already meant that the PS5 in graphics performance will be a very big improvement. In addition, DF believes that GDDR6 is the most likely, the memory space width should still remain at 256-bit specifications, the frequency may be 14GHz, may also be 16GHz, so the memory bandwidth may be 448GB/s or 512GB/s one of the.
So how does DF determine that Oberon is a PS5 chip? They mentioned that in the test data, there were multiple modes of THE GPU above Oberon – “native,” “Gen 0,” “Gen 1” and “Gen 2” – where “native” and “Gen 2” modes, where the GPU opened all CUs and worked under 2.0GHz. Under Gen 0 and Gen 1 modes, it will lower the frequency and may also shut down some units, for example under Gen 1 mode, which will operate at a frequency of 911MHz and at this point the memory bandwidth will be reduced to 218GB/s, which is consistent with the GPU above the PS4 Pro. Similarly, in Gen 0 mode, this GPU “simulates” the PS4.
But there’s a little bit of doubt about the test data, which doesn’t mention that Gonzalo has hardware that helps speed up ray-tracing calculations, while another chip codenamed “Arden” has a feature on it, as well as vrS, a Navi 10 that currently doesn’t support. If Oberon’s specifications are still relatively reliable, then this Arden is quite outrageous, but that’s what the leaked document data says.
Arden – probably the chip above the Xbox Series X – has 3,584 stream processors, 56 sets of CUs based on a single CU with 64SP, which should be the successor to AMD’s belated Navi 12, a large GPU that is 40% larger than the complete Navi 10 above the RX 5700 XT. DF predicts that its single-precision floating-point performance will be 12TFLOPS with a operating frequency of 1.68GHz. The leaked data also provides a memory bandwidth – 560GB/s, how this unusual memory bandwidth is implemented, or wait for Microsoft to finally publish the parameters (possibly a hybrid memory interface).
If the Xbox Series X does use a chip of this size, the cost is not right. Of course, it’s the official version of performance beasts. The PS5 is likely to start at $399, but the Xbox Series X… But Microsoft is clear lying to the next generation with multiple hosts planning, first out of a flagship and then other small machines is also possible, even said not to be a few months on the E3 on the film tells you “we have a machine for the first time.”
Here’s a mention of the news we’ve got, the PS5 and Xbox Series X’s light-chasing implementation may disappoint you, and it may be done differently from NVIDIA, which AMD may adopt a “more hardware-and-software combination” approach to achieve light pursuit. There’s a ready-made DXR on the Xbox side, but Sony’s side… It must be his own set of wheels.
Next generation hosts will be launched this Christmas holiday, and depending on the previous generation, we’ll soon know the details of them.
