last gen was an outlier as they moved from Samsung to TSMC. the 3000 series benefited from the 2000 being meh (intentionally or not). Not sure it's realistic to expect insane gains anymore.
A 20 or 30% performance gain is double by moving to TSMC 3nm process. But there is the problem of the power draw which keeps going higher from generation to the next.
Yeah if they couldn't give them more performance for reasons at least give them more vram its looking like if you don't factor in 3x compromised frames the 9070 is going to look much better than the 5070 in 2025..
AMD has an even bigger window than ever before but they'll probably still F it up....
RDNA3 seemed to have bottleneck somewhere, the specs on paper look better than the performance.
AMD has a better chance now to release good product, if we take the RX 7600XT for example, it's a monolithic chip built on 6nm. The RX 9070XT reportedly doubles the resources and built on a 4nm process (much more dense/efficient). If we account for the IPC/RT improvements for RDNA4 and the higher clocks, raster performance should be around that of RX 7900XT and probably more efficient with better RT.
If priced right the 90x0 cards can be great.
