AMD Radeon HD 7990 Review: Dual GPU Comeback

[GhostRyder]

When you install the new version of catalyst it does uninstall the old...

I just updated a few days ago to 13.4 and it was just download and install and the other version was gone. I guess though back at 12 series you did have to uninstall first, though I cant remember if I had to or not.

 

[Jad Chaar]

The new version overrides the old... you should uninstall before installing the new driver to prevent old issues from transferring.

Amstech, your one to talk since your the one who started this war. Posting your "Opinion" saying NVidia cards are just better than AMD's on the HD 7990 review was the most immature thing to do. Your just a mad fan boy who cant take it when a card is better than one of your precious NVidia cards..

I am just a consumer riding the wave baby, and Nvidia has been #1 for about 5 years now in my book. Radeons are bang for your buck GPU's that are offer less then a GTX so they are priced less then a GTX. Nvidia is the current GPU king, AMD is what they have always been... a bargain. And a damn good one at that.

AMD cards are better for OpenCL and OpenGL, but nVidia is king in Directx. Full stop!

 

[GhostRyder]

Yea Amstech, that's why The HD 7970Ghz edition is at the top of the charts on FPS in games. From what I see, seems to be Nvidia is below AMD on almost all FPS charts nowadays? Whose the king again?

 

[amstech]

Whose the king again?

Titan.

 

[GhostRyder]

HD 7990 is above the titan from what ive seen

 

[Jad Chaar]

It matters what the title is actually. Some franchises are partnered with either AMD or nVidia. Usually the game is optimized more toward the sponsored manufacturer. Look at a benchmark of Batman Arkham City, which is favored toward nVidia because they are sponsored by them, and therefore implement PhysX, something AMD doesnt have.

 

[GhostRyder]

Well technically when games use PhysX, if you have an AMD card, it just defaults the PhysX to your processor. But yea there are games that favor either company, but on the note, it seems more games that are huge are at the moment, higher on AMD cards.

But the Titan is single GPU, it uses a ton less power. The 690 uses 75W less than the 7990 while still being on par with it. The 6GB of GDDR5 (3x2) is the only thing that will be favored by enthusiasts running multi monitor setups vs. the 690s 4GB (2x2).

Lol thats a dual GPU.
SLi Titans would wreck that thing.

 

[Jad Chaar]

I am neutral in terms of AMD vs nVidia, but I think nVidia wins this battle.

 

[GhostRyder]

Yes but the titan also costs 1000 dollars and is pretty far below it I believe around 20-30 percent in most cases. Plus the fact is you could buy 2 GTX 690s of HD 7990s for 1000 bucks and get around equal performance of 3 Titans with current drivers according to the benchmarks which will probably be improved. But you have to spend 3000 to do that vs 2000 with the other 2 Dual GPU cards.

 

[GhostRyder]

Meant to say 1000 bucks each

 

[Jad Chaar]

Lol thats a dual GPU.

Not many people have $4000 for just GPUs lol.

 

[GhostRyder]

Exactly my point, your paying a higher premium to gain a little more performance and more ram when you can (If your looking at spending lots of money and trying to figure in terms of each card) lots less buying 2 Dual GPU cards over having to buy 3 of the titans to get a bit over the 2 Dual GPU cards which is too much.

At an 800 price point, the card would still be pricey, but I could see it matching better at price to performance and being a good buy, as it is now, it overpriced.

And in terms of Multi-Monitor, there are 4gb 680s and the 6gb HD 7970 GHZ edition which cost a whole lot less than the titan (minus the upped power of the titan of course, but a better price to performance ratio)

 

[Jad Chaar]

Also werent we arguing before about how SLI and Xfire is bad?

 

[GhostRyder]

HD 7990 is above the titan from what ive seen

Lol thats a dual GPU.
SLi Titans would wreck that thing.

And that would cost 2000 Dollars to "Wreck it" and even then, the margin is like 2 of those is 1.5 HD 7990. Meaning at 3 Titans which is 3000 Dollars VS 2 HD 7990s (Or even 690's) at 2000, that's basically a tie with a slight edge to the titans for 1000 Dollars more. A slight edge, is not worth 1000 More dollars.

 

[GhostRyder]

SLI and Xfire have their issues no doubt, but still its not enough to validate the price of a titan.

Physx can also be calculated on cpu or hybrid amd+nv gpus,

but physx is itself buggy and gives you unplayable fps and that's why only a handful of games uses it...simply put 95% of devs don't want to use physx,it's that buggy and marketing thing as "we give you physx on nvidia".
for one ex,-
in arkham city at 1080p in gtx 680,arkham city hovers around 2-12 fps minimum...

physx has been an abomination of nvi marketing since 2003 to notoriously trick customers...

and CUDA is been good for some software specific application as da-vinci code color correction,adobe effects and name a few..
But even in CUDA department,nvi is looking more or less irrelevant now as their one biggest plus finally dropped the balls on CUDA support,

"AMD & Adobe Collaborate: Next Version of Premiere Pro Supports Hardware-Acceleration on AMD Graphics",they claims opencl will be 20% or more faster than CUDA as nv proprietary-

tomshardware.com/news/Adobe-AMD-Premiere-FirePro-OpenCL,21872

and even amd hd3d is way more flexible and user-friendly than nvi 3d surround proprietary and also requires extra 150$ kit...Also Linus said that HD3D is better than 3d surround in present scenario...

 

[Jad Chaar]

Average FPS is really all that matters. Adobe After Effects is optimized for CUDA, Photoshop uses OpenGL I think.

 

[Burty117]

I respect others opinions

No you don't, end of story... If you read back through the comments, your the only troll in this thread, and a disgustingly ignorant ATI fan boy at that...

No mean feat since Nvidia didn't acquire PhysX from Ageia until 2008

But even in CUDA department,nvi is looking more or less irrelevant now

Not really, Nvidia is a signatory of Khronos Group (OpenCL), so Nvidia leverage pro (Quadro/Tesla) CUDA based software such as CompleX/OptiX/SceniX in a market where they have graphics 85% market share largely based upon that software ecosystem. As OpenCL achieves wider integration Nvidia then has that ecosystem in place to take advantage on a case by case basis, since porting CUDA to OCL is a relatively trivial matter...

If you have an application already written in C for CUDA, it is simple and relatively straightforward to convert the program to OpenCL™.

[ AMD OpenCL Developer ]
Like anything Nvidia do, it's about maximizing profit.
/OT
Anyhow, the topic is the HD 7990 I believe...

 

[Jad Chaar]

I feel like a noob fighting for both sides lol.

Another NVidia fanboy jumping in on the bandwagon I see. Yeah ignore the fact that your team starts fights like this just to cause trouble and then defend him when someone responds. Typical fan boy is typical. Ive probably owned more NVidia cards than you burty and built probably more computers than you since I started learning in the middle of the 90's. And im not an "ATI Fanboy" since I believe the company ATI of which you speak of no longer exists (Sheesh get your facts straight) and my last 4 cards have been NVidia. Ive only actually owned 1 ATI card in the past and the rest have been NVidia and now I own 2 AMD cards.

Try and get over yourself, and go back to the 7990 please, your fanboyish responses are getting old and we all know your just mad that an AMD card has trumped you. If you don't want to know about the card or AMD cards in general, get off the threads about those cards.
