Last month, specs for the rumored PS5 Pro specs were leaked. Reports suggest that Sony could release the PS5 Pro by the end of this year. Now, The Verge has obtained a full list of specs. Sources say that Sony is asking developers to ensure their games are compatible with this upcoming console, with a focus on improving ray tracing.
The PS5 Pro model, codenamed Trinity, will include a more powerful GPU and a slightly faster CPU mode. The GPU rendering will be “about 45 percent faster than standard PlayStation 5,” according to documents outlining the upcoming console. The PS5 Pro GPU will be larger and use faster system memory to help improve ray tracing in games. The speed will be up to three times better than the regular PS5. The CPU will be the same but a new mode will clock it higher. “Trinity has a mode that targets 3.85GHz CPU frequency,” says Sony in a document to developers. This is around 10 percent more than the regular PS5. Sony will offer developers the ability to pick between a “standard mode” at 3.5GHz or the “high CPU frequency mode” at 3.85GHz.
The standard mode operates like a regular PS5. In the new high CPU frequency, more power gets allocated to the CPU, which means slightly less power goes to the GPU. The GPU is downclocked by around 1.5 percent in this mode, which results in “roughly 1 percent lower performance,” according to Sony.
In addition to the changes to the GPU and CPU, the PS5 Pro will also have changes to system memory for developers. Sony is increasing the system memory by 28 percent to 576GB/s from the standard 44GB/s on the regular PS5. Sony says the bandwidth gain may exceed 28 percent” as the memory system is more efficient on the PS5 Pro.
The increase in the PS5 Pro’s system memory “may be useful” for Sony’s new PlayStation Spectral Super Resolution (PSSR) support. PSSR is Sony’s upscaling answer to NVIDA’s DLSS or AMD’s FSR to improve frame rates and image quality on PlayStation. Sony has built a “custom architecture for machine learning” on the PS5 Pro, which supports 300TOPS of 8-bit computation.
The new architecture supports Sony’s PSSR upscaling solution which is designed to replace a game’s existing temporal anti-aliasing or upsampling implementation. Sony notes that “inputs are quite similar to DLSS or FSR” and that full HDR support is included. The support requires around 250MB of memory which is why the PS5 Pro should help bring everything into fruition. Sony says there is around 2ms of latency involved in upscaling a 1080p image to 4K and that the company is working to support resolutions up to 8K and even improve the latency in the future.
The changes point to the PS5 Pro being far more capable of rendering games with ray tracing enabled or hitting higher resolutions and frame rates in certain titles. Sony is encouraging developers to use graphics features like ray tracing more with the PS5 Pro, with games able to use a “Trinity Enhanced” (PS5 Pro Enhanced) label if they “provide significant enhancements.”
The Verge reports that developers are able to order test kits right now and Sony is expecting every game submitted to certification in August to be compatible with the PS5 Pro.
