The newly leaked details of the PlayStation 5 Pro have left tech enthusiasts confused about its GPU. According to early shipments and teardown analysis, the console boasts a larger internal SSD, extra RAM for the operating system, but a GPU that doesn’t quite match expectations.
Sony’s latest console upgrade includes a more substantial SSD, with a raw capacity of 2 TB, although some storage is reserved for console administration. The new console also features an additional 2 GB of DDR5 RAM on its motherboard to improve performance. However, the most intriguing aspect of the PS5 Pro’s GPU is the use of what was initially expected to be an RDNA 3-based chip.
In contrast, the original PlayStation 5 graphics processor utilizes an RDNA 2-based design with 36 compute units and a peak FP32 throughput of 10.3 TFLOPs. The new console’s manual confirms that it has 60 compute units, but clocked at around 2,175 MHz – significantly lower than initially reported.
While some speculate that this could be an RDNA 3-based design, others believe that the unique driver compiler might make it harder to identify. A closer examination of GPU traces in games with RX 7000-series cards suggests that dual-issue instruction rarely appears, but this doesn’t entirely rule out the possibility of an RDNA 3-based design.
The exact nature of the PS5 Pro’s GPU remains a mystery until further technical analysis or die-shot images become available.
