Just got abit curious about this and i was wondering if someone had hard data to compare with.
Obviously running at 7970 at those speeds on anything other than LN2 isn't a possibility (you would need a nuclear powerplant to do so as well) and it seems to be a speed most 980s reach on air so no a very practical comparison but an interesting one. I also know a 290X (@ stock) would be left behind by a 7970 at those speeds but what about the current champ?
They both have around the same core count (~2000) and TMU's (128), but the 980 has 2X the amount of ROPs and 1GB more VRAM. Of course they also have completely different architectures but it seems GCN scales better with frequency than Kepler and Maxwell and is more comparable to Fermi so would a 1500Mhz 7970 challenge a 1500Mhz 980?
