It will be recalled that the CEO of Sony Interactive Entertainment has confirmed the impossibility of launching games from PS3, PS2 and PS1 on PS5. It’s a shame, but it’s not the worst news. Many rumors say about problems with production, although official sources deny them. However, fans will not be fooled, many users say that if earlier Sony claimed that most of the new games will be released exclusively for the PS5, now the situation has changed, the company plans to release most of the new games for the PS4. This may indicate that the company is facing some problems in one way or another, in any case, this is how the news in the community of console fans is interpreted.
It’s no secret that the PlayStation 5 lags behind its competitor in terms of computing power. This mainly applies to the graphics subsystem. This is also not pleasing, but the higher frequency of the graphics chip, efficient data compression technologies, fast solid state drive and other features left hope that in general the existing shortcomings will be offset by a number of significant advantages. But even here not everything is so simple.
PS5 Var thing 🤦
to match XSX/XSS CPU at >= 3.5 Ghz
GPU has to lowered the clock=5.5TF
1.High CPU=AI/character on screen
added blur etc, drop the res (dynamic)
as GPU dropped to 5.5TF
2. Sony style cinematic scripted
3. mostly at the game
PS5 = 8.3TF pic.twitter.com/C6g35SFwPL

One technician, known on twitter under the pseudonym blue nugroho (@blueisviolet), notes that the actual performance of the PlayStation 5 will be lower than stated. Once again, the old information that the graphics chip (probably Navi10 Lite) will be based on a modified first-generation RDNA architecture is emphasized. And now it has become known how SmartShift technology will control the dynamic frequency of the processor and PS5 graphics chip.
At the maximum load on the processor, its frequency will be 3.5 GHz, and the graphics chip will work only at 1.2 GHz. Under conditions of uniform loading, the frequency formula takes the form of 3.2 + 1.8 GHz. The maximum frequency of 2.2 GHz graphics chip can reach only when the processor is running at 2 GHz. This reduces the actual performance of the PS5 from the stated 10 Tflops to 8.3 Tflops. According to blue nugroho, the console will have to use various optimizations: reduce image quality, use blur, apply a dynamic change of resolution to maintain a stable frame rate.
