More PS5 Pro Details Leak

gamerant.com:

Additional details surrounding the upcoming PlayStation 5 Pro's graphical processing unit (GPU) have leaked. The technical specifications of the heavily-leaked mid-generation upgrade of the PS5 have been out there for a while, but a new report sheds light on the more intricate details of its GPU.

A stronger version of the PS5 has been widely speculated to be a reality since the back half of 2023, but leaked documents from Sony's official developer portal unofficially confirmed the PS5 Pro back in March 2024, codenamed Trinity. The leaked specs show a much beefier GPU than the current PS5, tipping the scales at an impressive 33.5 teraflops while utilizing AMD's newer RDNA 3 architecture. Although the CPU sees a milder 10% clock-speed upgrade on the same Zen 2 architecture, exciting details about Sony's brand-new image upscaling solution, PlayStation Spectral Super Resolution, also surfaced from the documents.

Thanks to some sleuthing from Digital Foundry, new details about the PS5 Pro's GPU have been procured. The earlier leak showed that PS5 Pro has 30 WGP (Work Group Processors) churning out 33.5 teraflops, which translates to a 227% jump over the standard PS5's 10.23 teraflops. However, Sony's estimations in the documents claimed a 45% improvement for the Pro, leading to a discrepancy. The latest information clears this up by taking the PS5 Pro's newer GPU architecture into consideration, which counts teraflops differently (dual-issue FP32 support).

The PS5 Pro's GPU will also have a base clock speed of 2.18 GHz, which can be boosted up to 2.35 GHz, an 8% improvement over the vanilla PS5. The GPU also features an improved cache structure, with the L1 cache doubled from 128KB to 256KB and the L0 cache doubled from 16KB to 32KB. These optimizations are apparently for maximizing ray tracing performance, reportedly a big push for PS5 Pro. Lastly, DirectX 12 Ultimate features like mesh shaders, hybrid MSAA, and hardware support for variable rate shading, which are all
