Recently, PlayStation chief architect Mark Cerny was interviewed by Digital Foundry. He said that the hardware performance of PS6 will not be greatly improved, and the changes will come more from the application of technologies such as AI and ray tracing.

Mark Cerny said that compared to pure "hardware performance" upgrades, the reason why PS6 can achieve a generational leap over PS5 is more due to the application of technologies such as AI (artificial intelligence) and ray tracing.This is also recognized by other hardware manufacturers: nowadays, whether it is the improvement of the computing power, processing power, memory and other core configurations of the host or computer, the experience improvement brought by it is far less obvious than that of previous generations of products.The industry has reached a bottleneck - to achieve minimal visual improvements, the hardware costs required are getting higher and higher.

The solution lies in processing data from the processor and graphics card in a new way, and allowing this data to be transferred more efficiently between hardware components.Image scaling technologies implemented through machine learning training, such as NVIDIA DLSS, Intel XeSS, and AMD FSR, have been applied a few years ago. This is the first step in this direction.

Cerny revealed that future hardware (hosts, graphics cards, PC processors, etc.) will make greater progress in these areas, and basic performance will also be improved.He said: "Of course hardware performance is also very important, and we will seek breakthroughs as much as possible, but I believe everyone agrees that radical changes will come from AI and ray tracing."

This also means that future PS6 games may have more realistic light and shadow, more complex physics simulation, and a smarter and more dynamic game world driven by AI.
