You’re assuming it has increased IPC. Based off the demo, if THAT is their GOD card, IPC is less than 10%, and all gains are done by clock speed increases and some extra cache.A little follow up.
If RDNA2 achieved 10% IPC increase - 80 RDNA2 CUs at 1.8 GHz will perform just like 88 RDNA1 CUs clocked at 1.8 GHz.
2.2 GHz clock speeds are 16% above RX 5700 XT clock speeds(1887 MHz).
In essence, if AMD has found a way, that 256 bit memory bus is enough for 80 RDNA2 CUs that GPU should be, with full config, with 2.2 GHz around 135% above RX 5700 XT.
Around 10-15% above RTX 3090. In 4K.
And this is only with 10% IPC increase.
This is all theoretical calculation.
So we better pray, that 256 bit bus is enough to feed those CUs, and that AMD was able to find a way, that those CUs scale in performance, similarly to RDNA1 architecture.
We better pray they are sandbagging for the end of month, otherwise...
