And the Xbox will receive.
It is no secret that both the “large” next-generation home consoles will again be based on the AMD platform. It will definitely be a semi-order hybrid processor with Zen 2 processor cores and a Navi generation GPU.
The most important, of course, is the graphics processor. And there were almost no clear details about him, or at least there were no rumors. But now there is.
A well-known insider got information about four GPUs that can be used in the upcoming Sony and Microsoft game consoles. They are hiding behind the code names Sparkman, Arden, Oberon, and Ariel. The first two are related to the new Xbox, the second to the Sony PS5. At the same time, it is not very clear why there are two of them. In addition, Oberon and Ariel sources indicate the same parameters.
And here lies the most interesting. If you believe this data, Oberon and Ariel are Navi 10 with 36 CUs, i.e. with 2304 stream processors. Exactly the same GPU with the same number of execution units underlies the Radeon RX 5700 graphics card.
To begin with, it is worth noting that this option seems quite possible, since the performance of the RX 5700 is 15.9 TFLOPS. According to rumors, the performance of the PS5 and the new Xbox will be very similar, while the second is about 12 TFLOPS. Thus, Navi 10 in the above configuration is quite suitable for Sony PS5, if you focus on the available data and rumors.
But there is another side. The fact is that Navi 10 does not have blocks for hardware acceleration of ray tracing, and such a function PS5 has been attributed for a long time, like the new Microsoft console.
And the source confirms that support for ray tracing is not specified for Oberon and Ariel, but for Sparkman and Arden it is indicated. That is, the GPU of the new Xbox may turn out to be less productive than the Sony PS5, but at the same time it will be a GPU belonging to the second generation of the RDNA architecture and having hardware units for implementing Ray Tracing.
And if everything really is that way, a very strange situation will turn out. Nevertheless, the new generation consoles will appear only at the end of 2020 and will obviously be on the market for at least six to seven years, so the lack of hardware support for ray tracing is seen in this context as a clear drawback. But, of course, while all this is rumor.
Separately, it is worth noting that it is not yet clear exactly how the GPU performance in the new consoles will be considered, whether it will be identical for half and single precision. In certain scenarios, if we take into account the single precision of the existing Navi 10 GPU in the Radeon RX 5700, the figure is only 7.95 TFLOPS, and in this case it is unlikely that it will be used in the PS5.
