The Radeon HD 5970: Completing AMD's Takeover of the High End GPU Market

The Test
For the 5970 launch, AMD is launching the card with a special set of drivers based on the Catalyst 9.10 branch, version 8.663.1. These drivers have had a lot of work put in to their Crossfire abilities, both to enable Crossfire Eyefinity support on the 5970, and to improve overall Crossfire performance. The Crossfire performance improvement also cascades down to the 5800 series, where we’ve seen CF performance improve in Crysis and Dawn of War II, while we’ve seen Resident Evil 5 performance dip some. So we’ve rerun our 5850CF and 5870CF numbers with the new drivers an updated them accordingly; single card performance remains unaffected.
Also, for most of these games we’ve gone ahead and dropped all resolutions besides 2560. Crysis is the only game that even remotely struggles with the 5970 (and less so thanks to these drivers). Everything else gets 60fps or more at 2560.
Finally, we’ve gone ahead and benchmarked the 5970 at both stock at overclocked 5870 (850MHz/1200Mhz) speeds. Bear in mind that we did encounter VRM throttling at 5870 speeds however.

So yes. The answer is that the gpu is doing less work with vsync than without it.(dam still no edit button)Yojimbo - Wednesday, November 18, 2009 - link
The plural for a casting/shaping instrument "die" is "dies" not "dice."Lennie - Wednesday, November 18, 2009 - link
I am going to post this again here. Thought it may not get noticed since I posted it first as a reply in previous pages. Hope I wont hurt anyones feelings :)I thought everyone knew about Furmark and ATi by now. It used to be like this on 4870 series too.
It went like this, at first there were few reports of 4870(X2) cards dying when running Furmak. Further investigation showed that it was indeed Furmark causing VRM's to heat up to insane levels and eventually killing them. Word reached ATi from that point on ATi intentionally throttles their card when detecting Furmark to prevent the damage.
Yeah in fact the amount of heat load Furmak puts on VRMs is unrealistic and no game is able to heat up the VRMs to the level Furmark does. OCCT used the same method (or maybe even integrated Furmark) to test for stability (in their own opinion ofc)
So beware about Furmark and OCCT if you have HD4K or 5K.
The term "Hardware Virus" is rightfully applicable to Furmark when it comes to HD4K (and 5K perhaps)

I want to add that VRM overheating is quite tricky, since normally people only check on GPU temps.When you run Furmark you would notice that GPU temps are in acceptable range while at the same time your VRM's are cooking without you knowing about it.
So remember to always check your VRM temps when running graphics stability tests like Furmark or OCCT's graphics test specially when you're overclocking the card.
I use Riva or Everest to check on VRM temps.

The temp reading that is displayed by Everest is an averaged figure. The junction temp of the slaves is the critical issue. Even though the average temp may appear to be within bounds, there is the possibility that one of the slaves may be running abnormally. Volterra keep their specifications under NDA. What I do know is that the general configuration if one slave shuts down is that the remaining slaves take the load. The result is not usually pretty. I think ATI may have implemented throttling to prevent the kind of burnouts users experienced running OCCT GPU tests on the last gen.Personally, I think the 3 phase Volterra solution used on the 5970's is right on the hilt for current draw (circa 135 amps per GPU). I'd wait for non reference solutions with enhanced power delivery if you plan on overclocking this card long term or plan to stress it heavily when OC'd).

I should add that I'm assuming ATI used the biggest Volterra slaves rated at 45 amps each and not the 35/40 amp varieties.thebeastie - Wednesday, November 18, 2009 - link
Any one that has a clue is buying a proper case like the Storm Sniper Black Edition and fitting this with heaps of space to spare.Also I recommend a case with positive or at least neutral are flow.
The storm sniper has a dust filter on its 20cm side fan to push more air in and aid in the GPU fans air flow that will go out the back of the cards vent holes at the DVI ports.

Plan on getting one of these in another 7-8 months - The way I see it, despite being bleeding edge - ATI has a deadlock winner in this card and will produce only limited quantities so I'm kind of 'worried' about the availability & price down the lineSilverforce11 - Wednesday, November 18, 2009 - link
Wait til the end of December. Apparently the yeilds of cyrpress are going to be improved a lot then, so the prices will either remain the same or be lower a bit.However, since nV has nothing real for a long time, i dont foresee a drop in prices on ATI parts. Given the estimates, NV will have fermi out in april 2010, but not in significant quantities for a while after that. Im gonna grab a 5970 around xmas. :)

Dude I hate you already :p I just bought a 5750 - I dont have the necessary components that would not bottleneck the 5970, so I'm going to have to wait a while. plus the whole 3 new monitors thing for the Eyefinity
