I'm not asking to bench every 580 out there since that would be quite redundant, but the fact is that the 7970 is AMD's new arch, new single GPU flagship and if you are going to include the aspect of showing the overclocking performance of the 7970, then at the very least include an oc'ed 580 since it's the only card that is really in the same class. Not just show 2 580s with the only differentiating factor of vmem size vs a stock and oced 7970 even though there are alot of people with regular 580s that can achieve 100-200mhz over stock.
The people who seriously oc their cards know what their cards can do... also if anyone wants to look up the oc results for previous reviews they are more than able to..

What the review does is compare the 7970 with a stable of current cards available and then show what it OC's like.

I think your asking for way too much to get them to put other cards in that are oc'd as well..

As for an idea of they could take old oc results and then compare, well thats not going to happen as games get patched etc so the results would be skewed.

The most I think you can hope for is that they mention another cards abilities in the summaries of each section as an opinion or observation.


Great work as always guys, keeps the masses well informed with all (well more than anywhere else I look at reviews) the in's and outs as always.

I really wish in the Overclocking section they oced the 580 3gb since the MSI Lightning XE reviewed on this site got 1009mhz from its stock 775mhz. That's 237mhz over stock on 40nm.

The 7970 was only able to achieve 1078mhz from stock 925mhz which is 153mhz.

The stock 580 and 590 on both charts show virtually the same performance even though 1 setting was off.. High vs Very High.

Notice how the 580 Lightning XE oced rivals the 7970 oced.

I'd rather have 1 chart with all the same settings, but this is as close as I can find.
It's probably more useful to people if the reference cards are compared as they are a more accurate reflection of the true capability of the cards components and what you would reasonably expect to purchase in the majority of cards available. Aftermarket cards such as the Lightning distort performance perceptions considering they're higher quality components and realistically aren't representative of the sample population of cards.

Also, any comparison between the Lightning 580 OC'd and 7970 OC'd are inherently flawed considering at the time of review, none of the reviewers (SKY included) had the potential to overvolt the 7970, meaning whilst the Lightning is at its maximal potential, the 7970 is only reflecting what could be only a fraction of its true OC'd potential.

And I'm here still with a GTX 550 Ti, can't get over what a big improvement it is over my previous 8800GT. I'll just be hitting the 560 Ti when everyone else is fighting over these monsters.

OpenCL Host2Device and Device2Host and Asynchronous

Have you tested them with PCI express 2.0 and PCI express 3.0? The reason you don't see any differences is that games load their data heavily to the GPUs so as not to have the Device <-> Host bottleneck...
Do a test on this and then you will be complete otherwise you lack technical completeness...

2.0 vs 3.0 tests were done as seen in the article itself.

finally, do we know now what is the folding potential of the card? maybe the owners of the card could pitch in with some numbers. Or should we still stick with team green for the moment?

I still can't get any of the 7000 series cards to actually fold....

Maybe someone can help out?

I'm using folding client V7.1.48. Latest beta drivers (12.2?!?), client configured to fold 0x16 where possible (I'm not at home right now, so can't check to see if it's actually getting any 0x16 WUs). Getting about 6500ppd on my 7950 with a minor OC at 905MHZ.

Funny thing is that my 5830 gets the same or slightly better PPD.
