Earlier last week, TechTuber and prominent leakster provided information about the Sony PlayStation 5 (PS5) Pro and the console’s own upscaling technology, known also as Spectral Super Resolution or PSSR. Today, new information is shedding light on the alleged details of its internal specifications.
According to Insider Gaming, the PS5 Pro is expected to have a memory bandwidth of 576B/s or 18GT/s, which is a 28% performance increase compared to the current PS5. Additional details point to the new custom APU still being based on the Zen 2 architecture and having 8-cores but will either be based on a 5nm or 4nm process node.
The CPU portion of the PS5 Pro, however, will have faster clocks at 3.85GHz, compared to the 3.5GHz of the Zen 2 CPU in the current PS5. That boost in performance will apparently be done through a feature called “High CPU Frequency Mode”.
As for the GPU of the PS5 Pro’s custom APU, it is to be based on the RDNA3 architecture, which is a bump up from the RDNA2 template being used in the current PS5. This, in turn, is expected to offer as much as 45% faster rendering performance and up to three times faster ray-tracing performance. That, and the fact that it will be using a combined 60 Compute Units from the new GPUs, running at speeds of up to 2.18GHz.
BVH8 is interesting, not only confirms PS5 Pro is using RDNA4's RT engine but also confirms RDNA4 doubles RT throughput per cycle, something which hasn't been mentioned in any open source patch yet! 👀 https://t.co/dht9fDWF79

Still on the subject of the GPU, Insider Gaming also claims that the new GPU will take advantage of BVH8 traversal shaders. To summarise, BVH8 is an acronym for an 8-level bounding volume hierarchy for ray-tracing and is technically a feature of the yet unreleased RDNA4 ray-tracing architecture. Let us be clear: AMD has yet to announced or launch any future Radeon GPU using RDNA4. It sounds farfetched but it does lend an air of belief that the PS5 Pro and its GPU will be something of a hybrid of RDNA3 and RDNA4.
There’s still no word as to when exactly the PS5 Pro will be out but Sony is expecting it to be “as competitive as possible”. Like the Slim version of the console, the console is expected to ship out with a detachable disc drive and 1TB of storage by default, and not the paltry 825GB (667GB accessible) the current console comes with.
