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

Crysis: Warhead
As Crysis is the only game that particularly struggled under even a single 5870, this is the only game we’ve gone ahead and captured data for at resolutions other than 2560.
The 5970 gains the distinction of being the only single-card setup we have tested that can break 30fps on Crysis at 2560 – it’s enough to at least push Crysis in to playable territory here, even though we’ll gladly take more performance if we can get it. So Crysis hasn’t quite fallen yet, but it’s very close. It’s also something where the 5970CF results would be quite interesting if we had them.
Interestingly, the 5970 manages to lose not only to the 5870CF, but the 5850CF by a very slight amount. The 5970 is clocked exactly the same as the 5850CF and has 2 more SIMDs, so we certainly aren’t expecting it to lose here. This may be driver related or it may be PCIe bandwidth related (each half of the 5970 only gets 8x bandwidth) but we aren’t sure which.
Meanwhile the GTX 295 sees the first of many falls here. It falls behind the 5970 by 30%-40%. The 5870 gave it a run for its money, so this is no surprise.
Finally, overclocking the 5970 to 5870 speeds nets you another 14%-18% in performance, which is quite interesting since the theoretical difference is only supposed to be 15%. But these numbers are repeatable; the 5970 likes being overclocked here.

This looks like a sweet card. Certainly ATI is taking control of the market.One question though...
What happened to the Hydra by Lucid Logix? I haven't heard anything about it in a while. Theoretically, the Hydra should take 2 ATI cards and make them perform better than Crossfire can.
Any news?

there as been reviews of HYDRA already, what planet are you on?GeorgeH - Wednesday, November 18, 2009 - link
1) No need to be a douche.2) No Hydra 200 products have shipped, all current "reviews" have been done using Lucid's development hardware.
3) It appears that Hydra will not work well with dual GPU cards; it will see only one of the GPUs.
4) Early results show that Hydra offers roughly equal performance overall to Crossfire/SLI.
5) Link to one of the better articles I've read:

Wow - so we have a card now that plays the latest Crysis at 2560*1600, 4XAA with details at a smooth playable FPS. IMHO I believe we've entered a new GPU generation. Or new compared to the capabilities I'm used to.rcpratt - Wednesday, November 18, 2009 - link
Is there some way to set up a dual-monitor setup (2 x 1920x1080) to run in horizontal span mode (3840 x 1080), like you do with your three monitors, without an Eyefinity card? I'm currently running with a 4870 and haven't been able to find a way to do this.The0ne - Wednesday, November 18, 2009 - link
I haven't tried but you should be able to do this easily, using catalyst. There's an option there to flip your screens for horizontal/vertical views and duplicate/extend your screens. That should do it for you.I haven't use the flip feature but I use the extend all the time because I'm hooked up to my tv.

I've spent hours trying to find a way to do it with Catalyst, and I can't find one. Right now it's on extend, which just leaves the secondary monitor as the desktop, with no taskbar on the bottom, and leaves me unable to play games at 3840x1080.If anybody has an explanation or idea, I'd appreciate it.

To put it simple, no it's not supported. The only way you'll be able to use the second screen is with games that are explicitly coded to support dual screens (Supreme Commander?).Your only other option is to use a Matrox multimon device (forgot the name) or an EyeFinity card of course. No NVIDIA card will allow this either, it's not a driver issue.
Either way, 2 screens wouldn't be a nice experience anyway, with the big bezel right in the middle, I can't imagine any type of game where that would work (no FPS, RTS, RPG, racing game, ...)

That's what I was afraid of. Thanks. And yeah, I wasn't planning on playing with 2 monitors, but I was considering getting a third. Oh well, probably better that I can't blow the cash :)The0ne - Wednesday, November 18, 2009 - link
On the same topic, does anyone know why my dual screen setup resets after PC restarts/shutdowns? In addition, I HAVE to select duplicate first, set it and then switch to extend. Selecting extend first doesn't enable it. Using current driver but this was there with previous versions as well.I've Googled and read many forums but haven't encountered many users having this particular issue. This is consistent in XP, Vista and Win7 as far as I can remember.
4870 with Dell 30" and Samsumg 73" 1080P TV. Temperatures around 56C for video card. If you have any tips I appreciate them. Thanks in advance.
