** SINGLE GTX 580 3GB VS SINGLE 7970 3GB REVIEW BY OcUK **

Except that they are more expensive?

Anyway, my point is looking at the direction of how the pricing and performance headed, it is looking really bad for the customers.

3870->4870= wow!
4870->5850= oh my!
5850->6950= meh...
6950->7850/7870= yay, I can save a few quid on my energy bill a year. Extra performance? What extra performance?

This I agree with. The current pricing speculation shows an ill-minded approach by AMD to gain the performance crown back. Not for long though.

left is 6850 and such territory and up.
but saving a few energy bills does matter in the long run.
Not individually but as a group.

Bullcrap.

The graphics cards are segmented by their price range, not performance.

AMD is moving back to their old naming scheme, creating a new enthusiast segment, all that by upping the prices on their entire range which makes the cards no better value than the 6900 cards are today.

Hi there

For those interested, with Tri-Fire with this Xeon rig, maximum power draw at the socket has been 800W whilst the cards have been running Heaven and it typically sits around 700W under load, dropping to circa 150-200W at idle. :)

GTX 580 3GB OC vs ATI 7970 3GB OC


Right we've now pushed the ATI card to what I believe is its safe maximum of 1225MHz and 7800MHz core. There is still a tad more voltage to put through the card but this seems the sweet spot clock speed wise.

So with these new results, the ATI card is:-

43% Faster than an OC GTX 580 3GB at 1920x1080 in Heaven

50% Faster than an PC GTX 580 3GB at 2560x1600 in Heaven


So with the card overclocked to where it can go were seeing in this particular benchmark upto nearly 50% performance improvement over a GTX 580 3GB. :eek: :eek: :eek:

is that a stock clocked 580 ?
 
Gibbo, I can't remember how OC handle new GPU launches. Will they go straight up for sale on release date, or will you offer pre-orders at an earlier date?

Thanks

Wooo the GTX580 gets absolutely mashed in this test and the 500 series are good overclockers in their own right. Looking at these results does lend credibility to the story that's going around that AMD has 2300 shader core card on standby just in case Kepler is faster then what AMD expects.

BTW is a "PC GTX 580 3GB" better then a MAC GTX580 3GB?

what was the 580 clocked to?

902 / 4355

Any higher visual anomalies were present and they were rather hot.

In synthetic benchmarks such as heaven and 3D Mark ATI are now flying now can see what the cards can really clock too. I mean 7800MHz memory is mental and I think 8000+ is even possible, just too scared to dare go that high.

But 50% faster in Heaven at 2560x1600 is impressive, shows the cards have truly impressive raw power and crossfire now works a treat. :)
