I am concerned here mostly with very high, probably water cooled overclocks. We know that the GTX 580 will throttle when using "too much power," not just to protect the card. The 480 therefore uses much more power during load.
But what about the negative repercussions of this? I would infer that when doing extreme OCing, the 480 could reach a higher level of performance than the 580 could, do to the 580's power throttling. Now, this would only be practical over 900 MHz core for the most part, which was techpowerup's max OC on a 580. Now, say we take a 480 up to 1000 MHz using water. I believe I have seen threads with these kind of overclocks; GF100 actually ocs quite well if heat is controlled.
Now, what would win? A 580 at 900 core, or a 480 at 1 GHz? A 580 at 870, or a 480 at 950? I believe this would be a worthwhile investigation, to see if there is a point in which the 580 simply cant keep up with the 480. Also, things are a bit more complicated due to GF110's revised shaders, but is this worth, say, 50, 100, or possibly more MHz?
Also, at what clocks do a 580 = 480 in performance? Obviously it would very in application, but my hypothesis is that beyond a certain point, the 480 will outperform the 580 as it is stuck at maximum OC due to throttling.
So, it seems to me, for the uber extreme enthusiast for maximum performance, the 480 would win over the 580, (or rather, 4 480's win over 4 580's, assuming similar scaling XD)
and thus the 580 would be a second choice, unless a non reference card was introduced that did not throttle at uber OCs.
Thoughts?
