ATI Radeon HD 5970 Dual-GPU Powerhouse Review

Article Index:   
AMD's "Sweet Spot" GPU strategy over the last few years has been fairly predictable. Instead of producing the biggest, most powerful GPU possible--yields be damned--the company sets out to produce a relatively high-end GPU, using a cutting edge fabrication process, that hits a proverbial sweet spot between cost and performance. Then derivatives, and even multiples, of that GPU are used to flesh out a top-to-bottom line-up of graphics cards, that hit a broad range of price points.

It began with the RV670, which powered the single-GPU based Radeon HD 3870 and dual-GPU Radeon HD 3870 X2--hence the X2. Then came the RV770, which powered the Radeon HD 4870 and eventually the Radeon HD 4870 X2. The strategy has obviously paid off, as AMD is once again a price/performance leader in the GPU space, after some not-so-great performances like the R600, better known as the Radeon HD 2900 XT.  Knowing their strategy, it should almost come as no surprise that the graphics card we'll be showing you today, the Radeon HD 5970, has come to fruition. Although it doesn't follow the same naming convention as AMD's previous dual-GPU powered cards, the Radeon HD 5970 is nonetheless powered by a pair of ATI "Cypress" Radeon HD 5800 series GPUs, linked together on a single PCB by a PCI Express bridge, very much like previous X2 iterations.

Considering the fact that the Radeon HD 5870 is undeniably the fastest single-GPU powered graphics card currently on the market, this dual-GPU powered Radeon HD 5970 should offer performance that completely outclasses any other single graphics card on the market currently. In addition to killer performance, the Radeon HD 5970 also boasts all of the same features of the Radeon HD 5800 series, like full DirectX 11 support, ATI Eyefinity support, top-notch image quality and power efficiency.

We've got a Radeon HD 5970 in house, in full retail trim, courtesy of HIS that we've run through and array of benchmark tests. Read on to see how AMD's new flagship fares in light of competing single and dual-GPU powered solutions...

AMD's "Sweet Spot" GPU Strategy

AMD's release schedule with their latest barrage of DirectX 11 capable GPUs is outlined on the slide above. Of course, a lot of groundwork had to be laid over the years before the company could produce this line-up of products. As the above list of specifications and features show, the new Radeon HD 5970 is quite advanced in comparison to other current GPU products. But the chip does leverage technologies already implemented in previously released GPUs, so it's not all new.  As such, we'd recommend perusing some recent HotHardware articles to brush up on a few of the technologies and features employed by the new Radeon HD 5970...

The articles listed above cover many of the features available with the Radeon HD 5970, like CrossFire, the UVD 2 video engine, Catalyst Control Center, PowerPlay, GDDR5 memory, and more. There are, however, a lot of brand new things that were introduced with the Radeon 5800 series that we that we detailed in our Radeon HD 5870 coverage, so that article at the very least is a must-read companion to this piece.

OMG, I wasn't expecting a dual GPU solution so soon!

Reading review instead of going to sleep! Smile

 

Okay, just finished reading the terrific review. I would want to add that getting two 5850's (Oringal MSRP = $259) in crossfire might be a better option than this one. For one, it'll save you ~$80, while reducing power consumption. Secondly...there is a slight performance boost with the dual 5850's. Unless the price is reduced by....say $100, I see no reason to purchase this.

And so the battle for the fastest video card continues. This release is truly remarkable for ATI. Thinking that Nvidia has been
2 steps ahead with them last year. The 5970 sounds really beastly, doesn't it?

Crysis 2 here we come!

I'm surprised this came out as quickly as it did! When is the mobile 5000 series set for release?!

 

[quote user="ClemSnide"]

But if the $600 price tag is accurate, it's a good alternative to a 5870 for people who want the performance. I'm encouraged. I'll stick with the sweet-spot 5850 for now, but perhaps WoW: Cataclysm will support more than one GPU and by then the prices (and availability) will have settled!

And it's eligible for free shipping! Big Smile

The Sapphire card is $624.00 at Newegg, and just as conveniently out of stock.

 

I want this card. Dave, you could send me yours for further testing,..... really,......

Dave_HH 5 years ago

I want one too!  Ask Marco.  He's the only one that has them at this point on our team.  Two of em in fact! :P

realneil 5 years ago

Two? In crossfire? drool,......

realneil 5 years ago

Since my AMD board has only one PCIE connection, I can see buying it. I can't afford it, but I can 'see' buying it!

Ha!

Need my Coffee to continue,.................

Realneil speaks to my condition*. Since my favorite game doesn't take advantage of an SLI or Crossfire setup, I went with a single GPU slot motherboard, and chose the Sapphire 5850; at $265 it was a good deal from Amazon, assuming it ever ships.

Couple comments though:

  1. Why no 6-monitor capability? Since this is essentially two 58xx cards in one, shouldn't we be able to run six Eyefinity-controlled displays?
  2. >[HIS's card includes] a cool multi-purpose tool with screwdrivers and a level.
    A level?

But if the $600 price tag is accurate, it's a good alternative to a 5870 for people who want the performance. I'm encouraged. I'll stick with the sweet-spot 5850 for now, but perhaps WoW: Cataclysm will support more than one GPU and by then the prices (and availability) will have settled!

Ah, finally ATi has a decisive claim as to owning the #1 single slot solution.  Many people preferred 5870 to GTX 295, but the latter was a bit faster most of the time.  Now the king has arrived.  But with availability already lacking in the 5870/5850, good luck finding one before Christmas.

I believe that drivers still do not allow 6 monitors with Crossfire 5xxx series yet.  But when they do you might want it, but even then 6 monitors is a hell of a lot of pixels even for this beast.

marco c 5 years ago

It's also a question of board real-estate. If you want 6-monitors, you need six display outputs. There is a 6-output 5870 coming soon. No word on a 6-output 5970 yet though.

I'm kinda like a spammer here but different, though just as shameless.  Big Smile

I don't like this new naming scheme... it's more confusing. I don't want to have to decipher all these numbers lol the x2 was simple.. times 2... got it! They just over complicated it.
