The big two measurements me and most technical people were waiting for were the watts consumption VS performance on screen (perf per watt or FPS per watt).
Being two products almost identical to each other (navi2/zen2/gddr6), both built on the same silicon process together with excellent cooling solutions, it is acceptable to assume by default that the higher power consuming product will generally have the better performance on screen (FPS).
The first metric we got was a few weeks ago: The wattage consumption. Both consoles pull 200watts from the wall. Bizarrely Identical.
This suggested 2 weeks ago performance on screen would be pretty close. But there were doubts, specifically: The on-paper specs suggesting XSX was always going to be faster. The implication being that the high clock speed of the PS5 pushing it away from the ideal voltage/Mhz curve
The story so far after the first game face-offs:
- It would appear that the wattage metric is accurately predicting the low discrepancy between consoles.
- The different designs are negating the on-paper difference of ~20%
- There will be different bottlenecks in different areas of the game caused by the different designs.
- Operating silicon temperatures and Power Supply efficiencies are still relevant factors, and may give or take a few % to each other. Unknown quantity.
Cheers
