Sony has it especially easy this time. But the Playstation 5 Pro does, it will be a winner. Microsoft abandoned the half-generation Xbox, as sales of the current model did not meet expectations. Perhaps partly due to his late preparation and late start of production, when he did not have enough stock ready for release, he was unable to cope with the demand during peak sales. The media urged consumers to buy the more affordable Playstation 5.
Since our last report on the Playstation 5 Pro, some new information has emerged. The SoC will move from the original 7nm immersion technology and an area of 300 mm² (later upgraded to 6nm EUV production and an area of 260 mm² according to some rumors to 4nm production, which with an increase in graphics may be mean an area between 200-300 mm² (probably closer to the lower half of this range than the upper).
Nothing changes on the ~ 10% faster CPU, but on the GPU we learn that Sony presents it to partners as ~ 45% faster (data output is 28.6% higher, CU count is 66.7 % higher, while the average of these values is around 45%). In the case of ray tracing, the performance trend (with appropriate game optimization) should be significantly higher.

To ensure that the games are well developed, developers can already order test kits from Sony, which expects all new games released for the Playstation to be ready for the “5 Pro” model from August. Developers will be able to choose whether their game runs in normal mode, where the CPU frequency remains at 3.5 GHz, or in “high CPU frequency mode”, where the processor increases to 3.85 GHz and the basic graphics clock is reduced by 1, 5% (which in itself is supposed to reduce FPS by about 1%).
Developers can now use more operating memory. While with the original Playstation 5 they could allocate 12.5 GB for the game itself, with the Playstation 5 Pro you can use 1.2 GB more, ie 13.7 GB for the game.
Sony also offers a new PlayStation Spectral Super Resolution (PSSR) upscaler, such as AMD FSR, Nvidia DLSS and Intel XeSS. How it will fare in terms of quality and performance remains to be seen, but Sony boasts that it has developed “its own machine learning architecture achieving 300 TOPS performance with 8-bit precision” for the Playstation 5 Pro .Sony expects developers to use PSSR instead of the classic methods implemented by individual manufacturers/developers at the game level, and says the PSSR implementation is similar to AMD’s FSR or Nvidia implementation. DLSS. PSSR supports HDR and its use costs about 250 MB of additional RAM (so the extra 1.2 GB of memory that can be used) should be increased from 1080p to 4K costs about 2ms of time (latency), and in the future it is planned to support up to 8K (at the output) and, if possible, also until the time to reduce
The console is scheduled to be released in the fourth quarter to take advantage of the pre-Christmas shopping season. So tentatively, it looks like late October to November.
