Hi there


Well as promised here is some insight to some of the early benchmarks we've managed with the new ATI 7970's (Yes OcUK has 100+ in stock). The following benchmarks are just Heaven for now with the settings taken from the forum benchmarking thread. I shall do some more benchmarks tomorrow at maximum 2560x1600 resolution as this is where these cards excel.

For now though:-
7970 3GB
Core Clock - 1125MHz
Memory Clock - 6300MHz
Voltage - NO CHANGE (Stock)


SINGLE CARD

DUAL CARDS

TRIPLE CARDS

The scaling is very impressive and at these clock speeds there was zero signs are corruption or micro stuttering. Needless to say I am amazed and very happy.

Also another keypoint, even with three cards, maximum temperature recorded was 92c, with a single card it was 72c. They run cooler and quieter than previous generation 7970. :)

Well done ATI! :D

And why not against 580 3gb in same machine

92c is massive my 480s on air overclocked don't hit 92 and that's in an 800d

Placing a GTX 580 3GB in same machine tomorrow. :)

ATI Cards tend to run well into 100c, only 92c maximum with three cards and thats because they are all sandwiched next to each other.

We'd never recommend more than two, there is little point really as one is powerful enough, two will destroy anything you throw at them and well three or four is overkill.

What CPU is it? Something with no chance of bottlenecking three these monsters I'm sure.

Its NDA, but unfortunately it won't overclock as multiplier locked so its now a bad choice but as we don't have a free sample 3960X kicking about were going to stick with it, just can't mention what it is. But we believe a 3960X at 4GHz would be quicker.

in this bench my cards dont hit 60 id be intrested to hear what these cards hit in single crossfire running this bench


so your only in here to troll then?

72c was max under crossfire with fans at 20% which is silent and that was OC too under benchmarking, gaming will be slightly lower temp.

he will be using cascade dice or ln2 with massive volt mods

Yeah i don't want to mod the cards, I just want to see what they can actually do with stock cooler.

Three in Tri-Fire all sandwiched together managed 1125MHz core and 6300MHz memory with zero issue on stock volts. I could not go higher as overdrive sliders were as far to right as they go. I think a single card will probable hit 1200-1300MHz core with stock cooler so be good to try the AMD clocking tool he is to bypass the limits imposed by overdrive. :)
 
Andrew Moore did some testing last night in his home system with a pair of GTX 580 3GB in SLI with a CPU clocked at 5.3GHz, compared to my CPU here at 3.4GHz.

However even with that CPU advantage and him clocking his 3GB GTX 580's he could not break 3000 points in the Heaven benchmark. Wheras the ATI Cards break 3500 with absolute ease. :)
 
Hi there

Struggling for time today guys, but here is a couple of 3D Mark benchmarks with Tri-Crossfire in 3D Mark 11 & Vantage:-

Any good guys? :D
