| SvennoJ said: It's not accurate and not a great measure, but as comparison sort of useful to understand that 24 terraflops gpu (4x the X) is out of the question. X was a big upgrade in 4 years going up in price, Scarlett 3 years later with many other upgraded components can't afford that kind of GPU power when currently 16 is the consumer max. |
You don't need 4x the Teraflops of the Xbox One X to have 4x the GPU performance.
Scarlett's Navi-based GPU is NOT the same as the PC variant, it's taking features/tricks from RDNA2/AMD's next gen GPU architecture.
Navi on the PC has 25% IPC uplift over Vega (GCN 5.0).
Vega (GCN 5.) had a 5-10% IPC uplift over Fury (GCN 3.0).
The Xbox One X's GPU is derived from GCN 1.0 as that is the base hardware that the Original Xbox One is derived from with some new tricks taken from Polaris (GCN 4.0) so there are significant gains to be had irrespective of the teraflop number.
GCN is extremely modular so AMD was able to take some forward features and backport it to older GCN designs for various markets.
