You talked about the CUs. The PlayStation 5 now has 36 CUs, and the Xbox Series X has 52 CUs are available to the developer. What is the difference?
The main difference is that the working frequency of the PlayStation 5 is much higher and they work at a higher frequency. That's why, despite the differences in CU count, the two consoles’ performance is almost the same. An interesting analogy from an IGN reporter was that the Xbox Series X GPU is like an 8-cylinder engine, and the PlayStation 5 is like turbocharged 6- cylinder engine. Raising the clock speed on the PlayStation 5 seems to me to have a number of benefits, such as the memory management, rasterization, and other elements of the GPU whose performance is related to the frequency not CU count. So in some scenarios PlayStation 5's GPU works faster than the Series X. That's what makes the console GPU to work even more frequently on the announced peak 10.28 Teraflops. But for the Series X, because the rest of the elements are slower, it will not probably reach its 12 Teraflops most of the time, and only reach 12 Teraflops in highly ideal conditions.
Sony says the smaller the number of CUs, the more you can integrate the tasks. What does Sony's claim mean?
It costs resources to use all the CUs at the same time. Because CUs need resources that are allocated to the GPU when they want to run code. If the GPU fails to distribute all the resources on all the CUs to execute a code, it will be forced to drop a number of CUs in use. For example, instead of 52, use 20 of them because GPU doesn't have enough resources for all CUs at all times.
Aware of this, Sony has used a faster GPU instead of a larger GPU to reduce allocation costs. A more striking example of this was in the CPUs. AMD has had high-core CPUs for a long time. Intels on the other hand has used less core but faster ones. Intel CPUs with less cores but faster ones perform better in Gaming. Clearly, a 16- or 32-core CPU has a higher number of Teraflops, but a CPU with a faster core will definitely do a better job. Because it's hard for gamers and programmers to use all the cores all the time, they prefer to have fewer cores but faster.
Original find belongs to @M-V2, I did translation and some editing and @CJY had also made a translation post in Next Gen Thread. Someone sent me this and very interesting reading... If it's not tralsated them translate it on Google chrome https://vigiato.net/p/85342 Edit 1: @benjohn is a...
