In the competition between Microsoft’s Xbox Series X (XSX) and Sony’s PS5 console, the PS5’s paper size was completely lost in addition to the 5.5GB/s SSD hard drive, especially since the GPU was a big gap compared to the PS5. However, the PS5 has a GPU frequency of up to 2.33GHz, and Sony says it has AMD technical support and will not have any problems running.
In the PS5, in addition to the 8-core 3.5GHz Zen2 CPU, the main processor also uses the RNDA2 architecture GPU of 36 CU units, which is completely out of the xSX’s 52 CU unit, but Sony relies on a frequency of 2.23GHz far beyond XSX 1.825GHz, making the PS5 GPU floating point performance reach 10.28TFTF, and the 12PC2PC.
The question now is how long will the PS5’s 2.23GHz GPU frequency last? After the specification was announced, the world was skeptical of Sony’s hype, because AMD’s GPU, like desktop graphics, had just reached 2GHz, which was still a dynamic acceleration frequency, which was actually much lower than that.
In response to these questions, Sony PS5 system architect Mark Cerny also responded in a recent interview, he stressed that the PS5 will not have a problem, 2.23GHz GPU frequency is also achievable, PS5 thermal system design breakthrough is for this, they found a set of frequency combinations, CPU and GPU hot spots the same, so it is easier to dissipate heat.
In the past, developers used to fixed frequencies, this time the PS5 used dynamic frequencies, Mark Cerny said this will not be a problem, PS5 frequency is automatic processing, do not require developer participation.
From Sony’s introduction, ps5 dynamic frequency technology is mainly based on AMD SmartShift, which is one of the technologies used by the Ryzen 4000 processor, simply speaking, this is a dynamic frequency/power management technology, can be in the CPU, the nuclear display GPU and the stand-alone GPU intelligently adjust performance and power consumption, which demand is high to ensure that there are more resources, run higher frequency, to give higher cooling space.
