So yeah, performance in this game more than tripled with the same amount of CU. Most of this is due to clock speeds (7970 Ghz edition: 1000 Mhz, 7600XT: 2755 Mhz boost), but there must have been some IPC improvements also. What I'm surprised at is the gap between the 470 and 570, because it's functionally the same chip and the boost clock speeds differ only slightly (38 Mhz). Probably the higher TDP of 150W compared to 120W has allowed it to boost more and longer. Meanwhile one can clearly see the sharp increase in clock speeds with RDNA 2 resulting in doubling the FPS over the 570. Too bad the 5600 is MIA, it would have been a nice point of reference. And now we'll have to wait and see it the 9060XT will be added to the chart. |
Drivers, faster RAM and higher TDP.
That's where some big gains have been had... Especially during the Polaris era where AMD sought to overhaul their drivers so they weren't "second tier" to nVidia.
Now arguably better than nVidia in many aspects.
It wasn't unusual to see increases of 20% in some instances.
Interesting stuff that, despite the same number of functional units, we have had some decent gains, although... 26fps to 101fps or roughly 400% over a 13~ year period probably makes it seem less impressive.
Can confirm RDNA2 has double the performance over Polaris as the GPU I had before this was the RX580, which I sold for $600 AUD, which was the exact amount needed for the RX6600 during the Crypto craze. Haha But that was just slightly less than doubling.
Now if only we can get them clock normalized so we could analyze the IPC gains year on year, but that's probably a tall ask.
