Here's the story behind it
The PlayStation 5 is powered by a custom AMD RDNA 2-based GPU, which is roughly equivalent to the AMD Radeon RX 6700 XT in terms of performance. This custom GPU features 36 compute units running at a variable frequency up to 2.23 GHz, delivering approximately 10.28 teraflops of graphical processing power. This places it in a similar performance range as the RX 6700 XT, though direct comparisons can vary due to the custom optimizations and architecture of the console hardware.
In the PC realm, the Radeon RX 6700 XT is a close match to Nvidia's RTX 3060 Ti and slightly slower than the RTX 4060 Ti in raw rasterization performance.
In addition, the PS5 is equipped with a custom AMD Zen 2-based CPU. This CPU features 8 cores and 16 threads, running at a variable frequency up to 3.5 GHz. The Zen 2 architecture (used in the AMD Ryzen 3000 desktop PC CPU series, for example) was a significant leap in performance and efficiency compared to previous generations.
The PS5 is equipped with 16 GB of GDDR6 memory, shared between the CPU and GPU. This unified memory architecture provides high bandwidth and low latency, optimizing performance for gaming.
