PSSR upscaling is intended to enable 4K at 60 fps

According to current rumors, Sony is working on its own AI upscaling for the upcoming Playstation 5 Pro with PSSR (“Playstation Spectral Super Resolution”), which will enable the rendering of games in 4K with 60 frames and in 8K with 30 frames per second. like the website Insider gaming would like to have experienced. In some games, however, only 1440p with 60 fps should be enough.

Performance assessments are said to have been leaked

As the website reports, the first internal performance assessments from Sony itself are said to have been leaked. The upcoming Playstation 5 Pro, which is said to have a new custom APU (“Viola”) with up to 60 compute units and 3,840 RDNA-3 shaders with a computing power of 33.5 TFLOPS*, is already said to be available in two different scenarios with PSSR -Upscaling has been tested.

*) related to the “Dual-Issue” skill of RDNA 3.

Scenario 1**:

  • PlayStation 5:
    • Performance mode: 1080p at 60 fps
    • Fidelity fashion: 1800p at 60 fps
  • Playstation 5 Pro:
    • PSSR upscaling: 1440p at 60 fps

Scenario 2**:

  • PlayStation 5:
  • Playstation 5 Pro:

**) not officially confirmed.

These supposed performance estimates should be viewed with the greatest possible caution, as scenario 1 in particular does not really match the alleged performance increase of a Playstation 5 Pro, which can also probably rely on AI upscaling.

Rumors continue to grow

The Playstation insider is known for his advance information, which has often been accurate in the past Tom Henderson had already responded to several rumors in July last year and confirmed that Sony was working on a more extensive upgrade of the Playstation 5 under the code name “Project Trinity”, which was once again based on the Matrix film series, which is expected to be released in time for the end of the year as the Playstation 5 Pro should be marketed.

• Viola APU with Zen 2 + RDNA 3
• Performance of a Radeon RX 7800 XT
• 33.5 TFLOPS of FP32 computing power**
• 45 percent faster than the Playstation 5
• Up to four times the ray tracing performance
• Neural processor with 300 TOPS (8-bit)
• Release at the end of 2024

*) not officially confirmed. **) related to the “Dual-Issue” skill of RDNA 3.

The latest rumors are now bringing a hybrid GPU into discussion, which will combine RDNA 3 and RDNA 4 – but at the moment there is still a lot of talk about it. RDNA 3, RDNA 3.5 and RDNA 4 – now each of the sources wants to have its own “reliable” information. When it comes to pure additional performance, the “dual-issue” skill (from RDNA 3) should also be taken into account. The jump in performance is adjusted from 10.3 to 14.3 to 16.7 TFLOPS, which is probably the maximum. The rest is then made possible by AI upscaling with libraries such as PSML (“Playstation Machine Learning”), it is said.

The currently most realistic scenario for a Playstation 5 Pro provides for the following technical specifications. The clock frequencies are also said to have been leaked recently, but caution is advised here too.

The “up to 67 TFLOPS” mentioned everywhere refers solely to the supposedly up to 300 TOPS (“Tera Operations Per Second”) high computing power of the NPU (“Neural Processing Unit”), which is said to be based on XDNA or XDNA 2 . However, only Sony can provide real facts and will keep them secret until the end.
