780 or 7950cf - Page 5

post #41 of 61
Okay since you clearly have absolutely no idea what you're talking about and refuse to see that, let's try this:

If the 7990 does not use crossfire, what other technology does AMD have that enables using two GPUs at the same time in 3d applications?

The answer is they have none. All AMD solutions with more than one GPU use crossfire. Crossfire works exactly the same in different devices. Only difference is the interface through which the GPUs communicate. It can be a PLX chip/crossfire bridge, CPU socket, pci-e slot etc.

The technology is exactly the same.

Don't take my word for it, listen to [H]:
Quote:
Today marks the launch of AMD's Radeon HD 7990. The Radeon HD 7990 is a dual-GPU video card that has its two GPUs down on a single PCB that uses CrossFire to operate the two Radeon HD 7970 GPUs.

http://www.hardocp.com/article/2013/04/24/amd_radeon_hd_7990_video_card_review/

which is obvious. Almost everyone knows this. If you've ever used an AMD card with two GPUs on a single PCB you'll know that in order for it to work you will need to enable crossfire.

First, how can it be out of context? Is the very first sentence in that paragraph you quote from AMD.
Quote:
AMD CrossFire™
AMD CrossFire™ technology is the ultimate multi-GPU performance gaming platform. Unlocking game-dominating power, AMD CrossFire™ harnesses the power of two or more discrete graphics cards working in parallel to dramatically improve gaming performance.1 With AMD CrossFire™-certified AMD Radeon™ HD graphics cards ready for practically every budget and the flexibility to combine two, three or four GPUs, AMD CrossFire™ is the perfect multi-GPU solution for those who demand the best.
Obviously, you are so focused in the "DISCRETE" word that you just can see the big picture. So, I am going to enhance the discrete word for you: Discrete graphics are made with GPUs. Some are discrete single-GPU cards that can be Crossfire with another discrete single-GPU card by using a bridge. Other discrete cards are dual-GPU where each GPU is Crossfired by a Chipset. And a discrete dual-GPU card can by its part, be Crossfired with another discrete dual-GPU card by using a bridge and resulting in what is commonly known as "Quad CrossfireX": 4 GPUs in Crossfire*. That's this simple.

Secondly, I do have the right to change my mind when I realize I was being misinformed. I was a fool trusting in your words, when I knew how my card worked and the problems I experienced in the first place. I even said you where giving a bad advice saying HD7990 solves the Crossfire issues! It can't solve because it is a Crossfire itself.
Unlike you. I realize there's no difference between the systems. You were only playing with words, and you still persist in doing it and quoting dictionaries. Please. Stop.


*If what you claim is right, it would then be possible to do a 4-way HD7990 Crossfire (8 GPUs). But, we all know that's impossible...

Fortunately, I could see it in time but, other members of this forum, specially the "newbies" can take this misinformation as true.

I don't want to quote ALL of Alatar's posts but he is right.

I'll give you another example to strengthen the formality of "single Dual GPU" set ups and "Dual GPU set-ups"
1. There have in no way shape or form "added" memory to it....It is shared NOT combine AT ALL.
2. "Single Dual GPU" set-ups be it AMD or Nvida IS IN FACT SLI and CROSSFIRE!!.

Alatar and everyone else has explained these things over and over, I think it's just the user that misunderstands what is going on.

I find all this funny...

As far as the term "Crossfire," AMD defines it as a two or more discrete video cards working together. Whomever has a problem with that, needs to take it to AMD, not me.

Perhaps you should take the time to read through the thread next time before impulse replying thumb.gif

This guy, WOW.

Jesus H. Christ man, I've never seen so much misinformed statements spewed around this badly as if it were really true. It's like believing your own lie is real you believe it so much. (That's just an example man not saying your lying, just extremely confused. and misinformed.)

I know you trust [H], so here you are...

Gameplay Summary
What really is remarkable is how much better the GeForce GTX TITAN did at this resolution than we initially thought it would. In two games Tomb Raider and Sleeping Dogs the GeForce GTX TITAN matched the same gameplay experience as the AMD Radeon HD 7990. In one game, Hitman: Absolution GeForce GTX TITAN exceeded the gameplay experience provided by GeForce GTX 680 SLI.

In only two out of five games did we have to lower the in-game settings with GeForce GTX TITAN one notch below the AMD Radeon HD 7990. It was only one notch to boot, not low settings, never did we have to set low settings, GTX TITAN was at least at medium settings or higher at 5760x1200.

We were also surprised by the relatively low percentage differences between GTX TITAN and HD 7990 or GTX 680 SLI. We saw as low as 20-30% differences. The reason why we say this is low is because some of these differences could be made up by simply overclocking the GeForce GTX TITAN. In our recent overclocking GeForce GTX TITAN evaluation, we found that performances from overclocking yielded 15-20% better performance in games. Therefore, overclocking TITAN would bring those performance differences way down between AMD Radeon HD 7990 and GTX 680 SLI. That is mighty impressive for a single-GPU video card.

In all cases, Radeon HD 7970 GHz Edition CrossFire from two separate video cards was still the fastest, and best gameplay experience, for a lesser price.

I have nothing nice to say about you so I'm not going to say anything aside from the fact that you're just spreading misinformation.

As much as I like AMD at this point I'd glady take a GTX 780 over two 7950's as having one card just keeps all the problems I'd get with a SLI/Crossfire setup.

You could hold out and wait for the new Crossfire drivers to come out in June/July then sell off the GTX 780. thumb.gif

Don't get mad bro, Im only quoting HardOCP. Its was their finding that 7970 in CF was, overall, the fastest and provided the BEST gaming experience. You dont have to like it, but if you have a problem with it, you need to take it out with Brent.
