Sony may introduce new technology for PS5 Pro
Last year, reports emerged that the PlayStation 5 Pro had entered the final stages of development, internally codenamed “Trinity”, with its System on Chip (SoC) known as “Viola”, potentially manufactured using TSMC’s N4P process. Analysts speculate that Sony is poised to launch the PlayStation 5 Pro in the latter half of 2024, providing a suitable hardware platform for the anticipated 2025 release of “Grand Theft Auto VI”.
According to new intelligence obtained by Moore’s Law is Dead, the forthcoming model will feature support for PlayStation Spectral Super Resolution (PSSR), a technology powered by artificial intelligence (AI). Rumored to employ PlayStation Machine Learning (PSML) for super-resolution processing of input data, PSSR is capable of generating a color buffer with a current maximum resolution of 4K, with future iterations expected to reach up to 8K resolution.
The PlayStation 5 Pro’s GPU is reported to possess a machine learning capability of 300 TOPS (8-bit integer operations), along with 67 TFLOPS of 16-bit floating-point performance. Its peak single-precision (FP32) computational power is estimated at 33.5 TFLOPS, more than triple that of the current PlayStation 5. Leaks suggest that the GPU of the PlayStation 5 Pro, based on the RDNA 3 architecture, will feature 60 Compute Units (CUs), equating to 3840 stream processors, hinting at potentially higher frequencies between 2.18 to 2.45 GHz.
According to a leaked “Trinity Technology Overview” document from Sony, the PSSR supported by the PlayStation 5 Pro is an enhanced version of the Temporal Anti-Aliasing Upscaling (TAAU) technology, akin to DLSS or FSR, with complete HDR support and dynamic resolution, requiring no game-specific adaptation. Elevating resolutions from 1080p to 4K consumes 2ms of GPU cycle time, necessitating further optimization, yet such an upgrade library requires only 250MB of memory.
Previously, AMD has hinted at the possibility of incorporating machine learning algorithms into super-resolution technology, though no official announcement has been made.
