New information has leaked about the PS5 Pro. They come from Digital Foundry and affect the PS5 Pro's GPU. This could offer more teraflops than expected – if only in exceptional situations.
Sony continues to announce the PS5 Pro wait. Official documents, which have been viewed by both insiders and journalists, make it clear that it actually exists.

Digital Foundry is among the publications that have the details provided by Sony to developers. The technology editor Richard Leadbetter, who is based there, took another closer look at the information and drew conclusions about the built-in GPU.
Standard GPU clock speed of 2.18 GHz is conceivable
Leadbetter points out in his analysis that the specifications coming from Sony's developer portal point to a PS5 Pro with more than 30 WGP (Work Group Processors). They are said to deliver a performance of 33.5 teraflops. The standard model has 18 WGP, which enables a performance of 10.23 teraflops.
At least on the surface, it is an increase of more than 200 percent. However, Sony itself only works from a 45 percent higher passage, which could be explained by the RDNA 3 architecture and dual-issue FP32 support. Doubling the number of processed commands would “generally not lead to a doubling of game performance”.
According to Digital Foundry, the clock speed of the PS5 Pro GPU can be derived from the standard version. The latter has 36 computing units (two CUs per WGP) that run at a maximum of 2.23 GHz. Taking into account the 33.5 teraflops achieved with the PS5 Pro, a clock speed of 2.18 GHz could be used here.

PS5 GPU even with “theoretically” 36.1 TF?
It was previously suspected that the PS5 Pro had 56 CUs, four of which were disabled. This would result in a higher clock speed, which “perhaps offers a hardware balance that better suits the compatibility of PS5 games”.
However, according to Leadbetter, the developer information on the PS5 Pro suggests a lower clock frequency of the GPU in the range of 2.18 GHz – at least in general operation. There is also an indication that the PS5 Pro can boost higher than its standard counterpart – to a maximum of 2.35 GHz. This would result in a theoretical maximum of 36.1 TF.
“However, similar to the original PS5, system performance is limited by a power limit, so the GPU rarely reaches this maximum and only certain games achieve such a high boost,” the analysis continues.
However, the slight reduction in the general clock speed will probably not make a difference given the “abundance of computing power”.
Other points Digital Foundry highlights about the PS5 Pro's GPU:
- The PS5 Pro's GPU has been further developed to incorporate DirectX12 Ultimate features that were left out of the original console.
- The 4MB L2 cache per WGP remains the same, while L1 doubles from 128KB to 256KB to accommodate the larger number of compute units per shader engine.
With the additional power, buyers of the PS5 Pro do not get a next-gen console, which is not what it is intended to represent. However, games where the current hardware reaches its limits will also benefit. Higher resolutions and frame rates are the result and take the graphical experience to a new level. Another goal is clear Improved ray tracing effects.

It is not clear when the PS5 Pro will be launched. Insiders expect a launch in autumn 2024, so Sony may start with the new hardware in November.
