PlayStation 5 will be more powerful than the new Xbox, but the Sony console will not receive the support ray tracing
It is no secret that the two «big» home console next generation will be again based on the AMD platform. It will definitely be poluzakonnoy hybrid processor with CPU cores and GPU Zen 2 generation Navi.
The most important of course is the graphics processor. And that’s about it distinct details or even rumors almost was not. But now there is.
Known insider got the info from about the four GPUs that can be used in future game consoles from Sony and Microsoft. They hide behind code names Sparkman, Arden, Oberon, and Ariel. The first two are related to the new Xbox, the second to the Sony PS5. It is not very clear why they are two. Besides Oberon and Ariel source specifies the same parameters.
And here lies the most interesting. If you believe this data, Oberon and Ariel is Navi 10 with 36 units CU, that is, with 2304 stream processors. Exactly the same GPU with the same number of execution units is the basis of Radeon RX 5700.
For a start it is worth noting that this option seems quite possible, as the performance of the RX 5700 to 15.9 TFLOPS. According to rumors, the performance of PS5 and new Xbox will be very similar, and the second is about 12 TFLOPS. Thus, Navi 10 in the above configuration is quite suitable for the Sony PS5, if you focus on the available data and rumors.
But there is another side. The fact that Navi has 10 units for hardware acceleration of ray tracing, as a function of PS5 attributed long as the new console Microsoft.
And a source confirms that for Oberon and Ariel support ray tracing is not specified, but for Sparkman and Arden — specified. That is the GPU the new Xbox may be less powerful than Sony PS5, but it will be a graphics processor related to the second generation architecture of the RDNA and maintains hardware blocks to implement Ray Tracing.
And if everything really is what happens a very strange situation. Still the next generation console will appear only at the end of 2020 and it will definitely not 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, a clear flaw. But, of course, until it’s all hearsay.
It is worth noting that while it is not clear exactly how it will be considered the performance of the GPU in the new consoles, will it be the same for half and single precision. In certain scenarios, if we take into account the single precision available in Navi GPU 10 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.
