Rdna2 takes the lead in Sony ps5's GPU and 2.2GHz AMD's rx6000 is stable

Sony announced the detailed specifications of the ps5 host early this morning. The main processor, like Microsoft's xsx, is customized by AMD. The CPU is 8-core zen2, and the GPU is rdna2.

The main differences between the two sides are the frequency and the number of GPU cores, the CPU frequency of Microsoft xsx can reach 3.8ghz, 300MHz higher than the 3.5GHz of ps5.

On GPU, xsx is 52 groups of Cu units and 1.825ghz frequency, while ps5 is 36 groups of Cu units and 2.23ghz frequency.

It can be seen that Microsoft's GPU is strong in the number of cores and low frequency (relatively speaking), while Sony takes another path, with fewer Cu units but high frequency, which will reduce costs.

Microsoft lost the hardware performance in the battle between Xbox X and PS4. This time it was radical, but Sony was conservative. However, this matter is not our focus. The key is the 2.23ghz of Sony ps5.

The 36 groups of Cu units of ps5 are equivalent to 2304 stream processors, which is actually equivalent to the scale of rx5700 graphics card,But the 2.23ghz frequency is at least 200MHz higher than the current RX 5700 frequency, which means that the frequency is increased by at least 10%

the two are actually not comparable because PS5 are RDNA2 architectures ,7 processes, RX 5700 or RDNA architectures ,7 processes.


So much, what's the point? That is to say, through the GPU frequency of ps5, the frequency of AMD's next generation RX 6000 Series graphics card will easily exceed 2GHz, after all, the acceleration frequency now is close to 2GHz.

According to AMD's statement at the financial analyst conference at the beginning of this month, AMD will focus on optimization at the micro architecture level. With reference to the changes from Zen to Zen 2, rDNA 2 will be improved in terms of IPC, circuit design and clock frequency.

This is a 50% increase in energy efficiency compared to RDNA,RDNA2, which is significantly higher than TSMC 7 nm Process comparison 7 nm process performance, energy efficiency improvement.


If we consider that the host processor is more conservative in frequency than the graphics card due to space constraints, the desktop graphics card of rdna2 architecture will have greater potential.

In a word, after Sony announced the GPU frequency of ps5, a fan was absolutely shocked,The frequency of the next generation amd video card can easily start from 1.8GHz. The acceleration frequency of 2.2GHz is very normal. A bit more fierce speculation is still waiting for the acceleration frequency of 2.4-2.5ghz, it should be able to be done technically. It depends on how amd weighs Cu unit, frequency and power consumption.
