From roaming threads, reading reviews, talking to users, and personal experience; I would say the majority of Tahiti adapters, both 7950s and 7970s, can reach clocks of 1150 to ~1250MHz on the core.
If your primary concern is 1920x1080, why are you on a 5760x1080 performance thread?
Get to know what binning is and how it's done before you continue your laughing, why don't you?
I can give you a starting point: chips are binned to run at their stock clocks, nothing more. Stock clocks here mean the clocks that the cards are sold to customers with. For 7950s, that would be 800-1000MHz AFAIK. For 7970s, the range is 925-1200MHz AFAIK. Now: if one batch of basically the same chip is binned for, let's say 1000MHz, there should be zero chips in that batch not capable of running at 1000MHz. Another batch is binned for 800MHz: that means that the good chips in that batch will most likely run at similar max clocks than those of the first batch, but it also means there could be chips that won't make it to 1000MHz. Base your statistical analysis on those two batches and you get similar max clocks but lower average clocks for the second batch. See my point? Here's
something for further reading.
I would say the most of those threads are from 7950 owners who go and buy a 7950 because everyone is saying to them: "get a 7950 and clock it to 1150MHz, they can all do it, go for it". They go and buy one and behold: they don't all make it to 1150MHz regardless of voltage. The most pissed of 7950 owners are the ones who end up with a 7950 with locked voltage. I guess you laugh at them, too?
I've read my fair share about these cards and my estimates would put the average 24/7 usable 7950 at around 1125MHz and the average 24/7 usable 7970 at around 1175MHz. Hwbot's benchmarking averages on air are 1155MHz
for 7950 and 1214MHz for 7970
I'm in this thread because I wanted to bring forth the fact that frame rates are not all there is to comparing SLI and CF (which is very much on topic). I then revived this thread because of Tom's review showing the great results of using RadeonPro with a Tahiti CF. And finally, I keep coming back here because there seems to be some sort of a feeding frenzy for certain people who can't be happy with Tahiti being stronger based on facts, but need to go further twisting the truth to only include pro-Tahiti points of view and exclude all others.Edited by specopsFI - 11/12/12 at 8:43am
