All the rumours on the big boi so far, mostly based on this week's leaks (Moore's Law Is Dead, InsiderGaming) from the Sony documents that went out to third party devs :
- Rendering 45% faster than PS5
- 2-3x Ray-tracing performance thanks to
- PlayStation Spectral Super Resolution (PSSR) upscaling and anti-aliasing tech, Playstation Machine Learning (PML) and an AI Accelerator that supports 300 TOPS of 8 bit computation / 67 TFLOPS of 16-bit floating point. 2ms computation time penalty from 1080p->4K (DLSS on PC is 1.7ms) but optimization is ongoing.
- 33.5 teraflops GPU (based on RDNA 3 GPU with RDNA4 raytracing features. Different architectures so tflops not directly comparable to base PS5, but estimated increase is around 45 percent)
- 576 GB/s Memory (18GT/s) (up 28% on paper but higher due to more efficient layout)
- 3.85GHz CPU (up 10%) in High CPU Frequency Mode, where more power is allocated to the CPU and the GPU downclocks by around 1-1.5%
- 1Tb storage
- Detachable disc drive like the current slim
- Audio processor (ACV) runs at a higher clock speed resulting in the ACM library having 35% more performance - More convolution reverbs can be processed and more FFT or IFFT can be processed
Also leaked, two Case Studies of the PSSR tech for two unnamed first-party games :
Game 1 :
Standard PlayStation 5 1080p/60FPS Performance mode and 1800p/30FPS Fidelity mode
PlayStation 5 Pro – additional 1440p/60FPS mode using PSSR
Game 2 : Target – Add Raytracing to gameplay
Standard PlayStation 5 achieved 60FPS without raytracing, and PlayStation 5 Pro achieved 60FPS with Raytracing.
