The PlayStation 5 Pro GPU will deliver a maximum of 36 teraflops of power, and some of its changes will accommodate, among other things, faster ray tracing performance.
In a new video and post shared online today, Digital Foundry goes over some of the latest rumors on the mid-generation refresh from Sony, taking an in-depth look at some GPU details. According to information on Sony's developer portal, the upcoming console has 30 Work Group Processors delivering 33.5 teraflops of performance, as opposed to the 18 WGP of the base model, which delivers 10,23 teraflops. On the surface, this means that the PlayStation 5 Pro should deliver an extra 227 percent of performance, but this isn't going to be the case, as Sony itself suggests in its documents that the new console will only feature a 45% GPU performance increase over the base model.
By comparing the numbers of the base model and the Pro model, Digital Foundry surmised that the PlayStation 5 Pro's 33.5 teraflops figure likely suggests a 2.18GHz clock from its 60 compute units, lower than the base model. This, however, will not make much of a difference thanks to the ultra boost mode that will boost GPU clocks to 2.35 GHz that will deliver 36 teraflops of performance, although only a few games will boost that high due to the system's power ceiling.
Besides slightly different clock speeds, the PlayStation 5 Pro GPU will feature other changes over the base model. Its new cache structure, with doubled L1 cache and L0 size increase from 16KB to 32KB, will accommodate larger numbers of compute units per shader engine and faster ray tracing performance, respectively. In addition, the GPU of the new system will support DirectX12 Ultimate features not available on the base model, such as hardware support for variable rate shading, mesh shading support, and extra features for hybrid MSAA.
The PlayStation 5 Pro has yet to be officially revealed. According to rumors, it should be released before the end of the year.
