PlayStation 5 Pro rumored to beef up GPU and ray tracing, bring AI acceleration
The PlayStation 5 launched in late 2020, though it feels like it arrived later due to supply issues. A Pro model will reportedly arrive four years later with a much improved GPU, AI acceleration and other enhancements.
The GPU will be the biggest upgrade on the PS5 Pro. Rumors claim up to 45% higher rasterization performance and 33.5 TFLOPs of compute power. Future SDK versions will support resolutions up to 8K and higher frame rates with 4K @ 120fps and 8K @ 60fps being possible.
Ray tracing performance is set to include 2-3 times, even 4 times on some occasions. This is thanks to a massive increase from 18 BVH4 work groups to 30 BVH8. The so-called “Bounding Volume Hierarchies” help speed up ray intersection calculations (i.e. does this ray of light hit this object or not?). We will skip the technical details, but the digit after BVH means that each individual work group will be able to do more work.
The Pro will also feature the PlayStation Spectral Super Resolution upscaling and antialiasing technology (PSSR for short). This will be especially helpful for ray tracing, which sees computation demands explode as resolution goes up.
The PlayStation 5 Pro will also bring a custom machine learning architecture. An AI Accelerator will offer up to 300 TOPS of 8-bit and 67 TFLOPS of 16-bit floating point computation. This might be the most interesting part as modern generative models can create realistic textures and speech, write out text based on a prompt and so on – what can developers do with this?
The console will also come with a modest boost to the CPU, which will have a “High CPU Frequency Mode” that goes up to 3.85GHz (from 3.5GHz), a 10% increase. By the sound of it, the PS5 Pro is very close to thermal limits, so this mode will drop GPU frequency by 1.5% (resulting in 1% performance loss).
The Pro model will have faster RAM that does 18 gigatransfers per second, a 28% increase from 448GB/s to 576GB/s. This is needed to feed the beefier GPU.
The audio subsystem will also get a boost with 35% more performance that can be spent on higher quality sound effects.
The PlayStation 5 Pro is expected to have 1TB onboard storage and a detachable Blu-ray drive similar to the slim models. Sony might release the Pro model in Fall 2024, but there has been no official acknowledgment of the console.
