What you’re searching for is especially hard to find in this comparison since a 460 768MB also has reduced pixel throughput and memory bandwidth. It’ll always be slower, and even if the separation seems to grow larger can you really say it’s from VRAM and not those other two differences? Can you explain why our comparisons are invalid?
But even with equal otherwise cards that only have different VRAM, good luck find benchmarks cross mixing settings. You’re liable to find an all Ultra test in which both cards are unplayable and this can draw a false conclusion that “the card is too slow to use more than xGB of VRAM”.
In reality, cross mixing settings is the best approach, and less VRAM often means a lower mixing average, mostly through textures. With my 2GB 675M Fermi that’s comparable to 460 256-bit (it’s actually a very under clocked 560 Ti to the point where it performs similar) I often turned down shadows and lighting but kept textures up which still resulted in relatively high VRAM usage (although less than all max of course).
It's unclear what the smoking gun to convince you is. The (nearly) equal card finding playable settings exceeding 768MB should be evidence enough for you, unless you feel that passing the VRAM barrier doesn't result in penalties (stutter!).
Sure the specs of the 460 768MB differed slightly from the 460 1GB in areas other than VRAM, but the 1060 3GB differs vastly more than this compared to the RX 470/480 4GB. So if it's difficult to draw conclusions about the 460 768MB vs. the 460 1GB, then by comparison it must be impossible to draw conclusions about the 1060 3GB vs. the RX 470/480 4GB. Obviously that isn't the case
As far as a valid comparison goes the spec difference between the 460 768MB and the 460 1GB could quite easily be compensated for. Simply take the difference in performance between the two at launch as the baseline and compare from there. At launch the 768MB was roughly 8% slower than the 1GB on average, so any significant deviation from this would likely be due to VRAM.
Point is though if evidence is as hard to locate as you guys claim, then why do you keep using the 460 768MB as an example of a VRAM limited card?
Remember that you were the one who brought up the 460 768MB as a VRAM limited card relative to it's 1GB competition, so the onus is on you to prove that it actually was limited, if you want people to take you seriously.
And no, showing that the 460 1GB suffers from VRAM issues shouldn't convince anyone, since it doesn't have anything to do with the issue being discussed. The issue isn't whether or not the 460 768MB can suffer from VRAM issues, of course it can, every card in existence can if you crank the settings high enough. The question is if the 460 768MB suffers from VRAM issues relative to its higher VRAM alternatives (the 460 1GB, or the 1GB 6850/6870 on the AMD side), and obviously if both cards are equally VRAM limited in a given game/settings, then it doesn't suffer relative to the 1GB versions.
All of the tests from this thread?
All of the tests illustrates that the 1060 3GB can suffer from VRAM limitations, they don't show that memory is the bottleneck in most cases however.
We just went through this, and it's fairly obvious that the 1060 3GB does not (currently) suffer from VRAM issues in the majority of games.
Remember the plural of anecdote is not data.
