580 GTX DCU II to 7950 Boost

[SS-89]

Just bought this:

http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1157&pid=1713&psn=&lid=1&leg=0

Was just wondering whether I'll notice a sizeable boost in performance especially after ocing given my clock speeds in sig.

The reviews seem to suggest I will (compared to stock 580's) but I was wondering if anyone has made a similar move and whether the gains are decent? For reference I game at 1920x1080.

That link shows the difference between the 580 and 7950. The drivers used in that bench are also old and the newer 12.11 drivers give a sizeable boost to most games. I am sure games will feel smoother with the extra performance

 

[humbug]

Edit, it was done on 12.7 Drivers http://www.anandtech.com/show/6152/amd-announces-new-radeon-hd-7950-with-boost as usual that anand drop down thing is completely and utterly useless.
I don't even know why people keep going back to it.

Ignore it, its way way faster on 12.11 drivers.


Don't know if there is anyone around who did a similar thing, i went from a 6950 (which is about a GTX 570) to a 7870, the performance increase from stock is pretty sizable, overclocked to 1200 / 1500 it just smashes it.

Your going to see a pretty good performance increase.

Yh it's pretty hard to judge how much exactly as the 580 comparisons are at stock clocks. Anyway I'll know tomorrow when it arrives, I hope I have a reasonable clocker.

The 7950 beat the 580 (marginally) upon its release at stock clocks. Add in an overclock and the new 12.11 drivers and you'll be looking at a nice boost.

Enjoy .

But still you could have waited for 8xxx series.

But still you could have waited for 8xxx series.

But if you always waited for the next gen, you would never buy a card.

Life's too short to wait

I could have but I always tend to upgrade around this time of the year, (got my 580 last Nov). By the time I next upgrade the 8xxx series and 7xx gpu's would have least been out a while with stable drivers and better pricing.

Was you refering to my post?

No, i would have quoted you, its generalized.

Ok.

I still see it as a usefull comparison chart and knowing that AMD's new drivers gives a boost to most of those games, makes AMD look better IMO. I will continue to use it, as I couldn't find anything relative to a 7950 Vs 580.

I just wish Anand would update it as its miles out, to many people (not here) use it and claim it to be accurate today, even the 7850 matches the GTX 580 today.

I do agree it requires updating but so long as people are made aware of the older drivers, that should be fine. When comparing some of the older models, it is hard and sometimes impossible to find anything to show the difference.

So after a day of playing around overclocking and stress testing I've clearly got a decent clocker!

1230/1500 @1.22v (reported in GPU z, 1.287 in Trixx) diminishing returns after that point as it required nearly 1.26v just to get 1250 to bench without artifacts.

Temps max out at 70 degrees on the gpu (70 on vrm 1 and 72 on vrm 2) on my custom fan profile.

As a comparison to my old 580 in the hitman absolution benchmark @ 1920x1080 Ultra quality settings 4xmsaa

580 DCU ii @ 920/2300 = 34.2
7950 @ 1230/1500 = 51.6

So about a 50% improvement which is brilliant

That is a good clocker. nice
