Sony PlayStation 5 Pro: More GPU, ray tracing and AI power

The Sony PlayStation 5 Pro is scheduled to come onto the market in the fall with more GPU power, AI acceleration and new storage options.

The PlayStation 5 came onto the market at the end of 2020. Four years later, it finally seems to be time for the launch of the Sony PlayStation 5 Pro with a significantly more powerful GPU, AI acceleration and other improvements. According to rumors, the graphics will receive the biggest update with up to 45% more rasterization performance and a total computing power of 33.5 TFLOPs. Additionally, future SDK releases will support resolutions up to 8K and higher frame rates. Up to 4K at 120fps and 8K at 60fps are possible.

This is thanks to a massive increase from 18 BVH4 working groups to 30 BVH8 working groups. The so-called “bounding volume hierarchies” help to speed up the calculations of beam intersections. In plain language this means: Does this beam of light hit this object or not? The number behind the BVH value indicates how much work each individual work group can complete.

The Sony PlayStation 5 Pro will also include PlayStation Spectral Super Resolution Upscaling and Antialiasing technology (PSSR for short). This is particularly helpful for ray tracing, where the computational effort increases exponentially as resolution increases. The Pro console will also have its own machine learning architecture. Additionally, the AI accelerator can handle up to 300 TOPS of 8-bit and 67 TFLOPS of 16-bit floating point calculations. This might be the most interesting part, as modern generative models can generate realistic textures and language, write text in response to a prompt, and so on.

The console will also come with a modest increase in CPU performance. Sony calls the whole thing “High CPU Frequency Mode,” which increases the clock frequency from 3.5 GHz to 3.85 GHz. Apparently this 10% additional performance takes the PS5 Pro very close to its thermal limits. Therefore, this mode simultaneously lowers the GPU frequency by 1.5%, which in return leads to a performance loss of 1%.

The Sony console will also have very fast RAM. The transfer rate increases by 28% from 448 GB/s to 576 GB/s. The audio subsystem also gets 35% more power for higher quality sound effects. The Sony PlayStation 5 Pro is expected to feature 1TB of onboard storage and a removable Blu-ray drive, similar to the slim models. Sony could launch the Pro model in fall 2024, but there is no official confirmation yet.
