PlayStation 5 Pro GPU To Feature Max GPU Clock Of 2.35 GHz; Will Deliver A Maximum Of 36 Teraflops Of Performance

The PlayStation 5 Pro GPU is set to deliver 36 teraflops of power, which is meant to boost ray tracing speeds. In a recent video and post from Digital Foundry, the latest rumors about Sony's mid-generation refresh are explored, focusing specifically on GPU specifications. Sony's developer portal indicates that the upcoming console will boast 30 workgroup processors, resulting in 33.5 teraflops of performance compared to the base model's 18 WGP and 10.23 teraflops. While this appears to give a 227% performance boost, Sony suggests a more conservative 45% increase in GPU performance according to its documentation.

After analyzing the specifications of both the base model and the Pro model, DigitalFoundry concluded that the PlayStation 5 Pro's estimated 33.5 teraflops likely corresponds to a clock speed of 2.18GHz from its 60 compute units. That's less than the base model. However, this discrepancy is expected to be minimal thanks to the Ultra Boost mode, which will boost the GPU clocks to 2.35 GHz, resulting in 36 teraflops of performance. It's worth noting that only a few games will reach this high performance due to the system's power ceiling.

Aside from minor clock speed variations, the PlayStation 5 Pro GPU will introduce several changes compared to the base model. Its updated cache configuration, including doubling the L1 cache and increasing the L0 size from 16KB to 32KB, will enable higher compute unit density per shader engine and enhance ray tracing capabilities. Additionally, the new system's GPU will include DirectX12 Ultimate features not present in the base model, such as hardware support for variable rate shading, mesh shading support, and additional features for hybrid MSAA. The PlayStation 5 Pro remains officially unannounced, but speculation points to a possible release before the end of the year.
