We shouldn't celebrate a 37% increase in performance when there are 33% more cores. This is NOT a generational performance lift. This suggests almost ZERO ipc or architectural gain in Blackwell. Same tsmc node, apparently same IPC. What a joke.
The biggest joke is the 5080 though which is now half as powerful as the 5090. Remember when the 3080 was 83% as powerful as the 3090? Not a single one of us should buy a 5080 and send a strong message to Nvidia that we won't tolerate this shrinkflation marketing bs.
"The result appears to line up almost exactly with what we would have expected from the Blackwell flagship, thanks to its substantially higher core count."
If Nvidia had enlarged the 4090 die with 37% more cores and used the 5090 cooling design for ~575W instead of 450W, it would probably have achieved about the same. Therefore, we must not thank the core count but should first notice the huge increase in wattage. The more relevant other improvement may be the revised power connector so a card might last longer.
A recently uploaded listing on Blender Open Data has revealed how well the RTX 5090 performs in Blender, using the OptiX rendering engine. The result appears to line up almost exactly with what we would have expected from the Blackwell flagship, thanks to its substantially higher core count.
