Every generation, the same OMG, this is unpossible!
All you have to do is follow Sony consoles since the PSX, and you will see a trend, where there is an approximate generational leap:
- 5-10 times the computational power (measured in single precision FLOPs)
- 16 times the total system and graphics memory (measured in MBs)
They are constrained by price and thermal envelope of the console enclosure each time, as long as Moore's law keeps chugging along, the next console cycle is unlikely to change.
For example:
PS3: 512 MB, 300 GFLOPs (X360 ~ 200 GFLOPs)
PS4: 8 GB, 2 TFLOPS (not as cutting edge)
PS5: 128 GB, 20 TFLOPs (ballpark)
You acknowledge the PS4 isn't cutting edge, but you apply Moore's Law to say that the PS5 will be?
Choose one.
