In May, Sony announced that their next generation PlayStation console will utilize AMD’s NAVI GPU. NAVI is based on a new RDNA architecture which offers 50% better power efficiency and 25% IPC [Instructions Per Clock] gains over previous GCN based VEGA chips. This means that 10 teraflops [Tflops] NAVI GPU offers the same performance as 12.5 TFlops VEGA card. So how does it translate to console performance?
PS4 PRO and Xbox One X custom made chips offer more of a POLARIS based GPUs with few VEGA features. So both consoles offer lower IPC than VEGA GPUs. This suggests that the difference between next-generation console’s and NAVI based GPUs should be even greater that we thought. But how big of a difference we are talking about here most will ask.
German-based website – ComputerBase conducted an interesting test. They compared NAVI based RX 5700 to a similarly spec’d RX 590. Both cards were run at 1.5GHz and come with 2304 shading units. They created benchmarks with a few games such as Metro Exodus, Battlefield 5, Hitman 2 and others.
The results were staggering. On average NAVI based GPU performed 40% better than POLARIS based GPU. This suggests that the PlayStation 5 and the next Xbox should offer at least 40% more IPC that current-gen consoles.
Suggesting the power leap
Speculating a bit here now, imagine a 10.5 TFlops NAVI based PS5 that is around 350% more powerful than PS4 PRO and around 800% more than regular PS4 (Slim).
The way it work is this. It’s safe to assume that next-gen consoles should offer around 10 TFlops of GPU raw power. This NAVI 10.5 Tflops machine should perform like 14.7 TFlops Polaris GPU. Just for clarification, there are currently no 14.7 TFlops POLARIS cards as AMD jumped to VEGA for more powerful cards. This would mean that the PlayStation 5 should perform like a 14.7 TFlops PS4 PRO if one were ever produced.
This just shows how powerful next generation of consoles should be. These numbers may be off by 10%-20% as we do not know final specs of these new consoles but I hope I provided a clear hint of what to expect next year.
If you add 4x more powerful CPUs to the bracket we are looking at a real next generation leap over current consoles especially the base models.
