GPU: Scorpio is said to be 6 tflop and PS4 Pro is 4.2 tflop. That's a 42% improvement in flops, and we could be potentially looking at an even bigger real world advantage if Scorpio is using Vega, due to architectural enhancements. CPU: I got those from the various wikipedia pages for AMD's CPU architectures. AMD claims Zen is a 40% IPC improvement over Excavator. Excavator can process up to 15% more instructions per clock than Bulldozer. Bulldozer is a 9% single thread and an 18% multi-thread IPC improvement over Piledriver. As far as I know, Piledriver formed the basis for the mobile Jaguar chip (both released around the same time). So in theory at least, the upcoming mobile variant of Zen, which Scorpio would most likely be using if it is using Zen, should offer at least a 60% IPC improvement over Jaguar, maybe more. RAM: Scorpio is said to be 320 GB/s while PS4 is 218 GB/s, which comes out to 46% improvement. The possible 12 GB of memory comes from Digital Foundry's analysis of the Scorpio reveal video, where they noticed 12 memory modules on the CGI mock-up of Scorpio's motherboard. |
The question here would be how much would all this cost? Could it be a 450$ machine? I feel that would be the "sweet spot" for the Scorpio, anything above that and I think they will struggle.
It will be interesting to see how MS handle the Scorpio and their take on hardware going forward. I'm not too fond of these mid gen upgrades, but new hardware always interests me.
