GTX570 vs HD6970 - Equal? - Page 9

post #81 of 111
If I go with the 2.5 model I will do surely. I hope to decide today what I want to go with. No real rush, but it had been 3 years since I last upgraded. Haven't had this feeling of something new in a long while.


EDIT* I went for the EVGA 570 2.5Gb VRAM. Was close to getting the Gigabyte Windforce 580 but I decided against it at the very last second. Better for my wallet and for the new build in the new year.

Sweet setup leavesque...

but as arizon said , your results cant be used.


In my oppinion :

GTX 6970 has more ram than the 570gtx and is pretty much equal in everything except tesselation performance.

In my oppinion I would get a 6970 2gb card.....1.2gigs of ram aint enough...and thats the reason why I got my 6970's...i could have either gotten 2x GTX 580's or 2x 6970's.....and it was the price and amount of ram that was more attractive for me (2x 3 gigs was out of my budget)

Nice! Be sure to bench it for us. While I dislike the HD PCB 2.5GB Vram is pretty attractive.

TO OP:

Looks like Levesques benchmarks are invalid unless you play games where there is no tessellation. He admits to having tessellation turned off during those benches in this post.

Your planning on playing BF3? It's tessellation heavy. In fact one of the devs said it's tessellation (three times) heavy. Which brings us back to those previous benches that Scorpion showed. Again, we've just proved how on par these two cards are with tesselation turned on.

Whether anyone likes it or not, unlike Physx, tessellation is here to stay as long as any game with Microsoft DirectX is used. It may be minor visually to the naked eye but it's used . Below an video example.


AMD does provide support for tesselation in their cards as well. AMD video here demonstrates tessellation on the worlds first DirectX 11 graphics processor.


Here's what tessellation does and works. Please don't mind the Nvidia post but they work on their cards being able to render tessellation and have the best explanation here.

Tessellation is not proprietary to Nvidia like Physx, so both AMD and Nvidia cards have their duty to produce cards that work well with any DX games.

OpenGL games are the exception as tessellation is not used in those games.

Again, hope this helps you make your decision as I see you haven't updated us with which way you went and thought this was relevant in your decision making process. Equal to.

Tesselation is applied a lot like AA, 1x, 2x, 4x, 8x, 16x etc all the way up to 64x. As for the source, I don't know.

Sorry I just assumed everyone had seen this one. One of the producers of BF3 during an interview confirms that BF 3 is tessellation heavy using Frostbite 2 engine.

He also claims that to run BF3 maxed out safely (obviously) performance equal to 580's SLI. (I'm assuming Ultra with everything cranked up).

Naturally - two 6970's will do OR two overclocked 6950's and 570's to stock 6970/580 performance will suffice for maxed out settings. I'm betting he was exaggerating on that a bit.

I know.....what im asking is , what does 3x heavy mean?

I KNOW that ati is fine for tesselation of upto 32x.....thats the amd optomised setting atleast ........are they saying that its gonna be 3x 32x????? that would be worse than crysis!

what im saying is , is with tesselation of 32x amd will not be slowed down due to the tesselation(to explain this to avoid confusion...in a scene amd's tesselator will do say 100fps wile the rest of the gpu will do 60fps...giving you a frame rate of 60 fps...thus tesselation is NOT slowing down the gpu.)...when you go higher ammounts then the tesselation bottlenecks the rest of the gpu (so once again draw a scene , the tesselation engine will only beable to do 30fps wile the rest of the scene is drawen at 60fps.....giving you a frame rate of 30fps....so now tesselation is slowing down the gpu)

I just meant a lot of tesselation "3x heavy" was just wording (slang). As above video showed, just meaning a lot of tess. It's not a technical term. LOL. Sorry I used it and confused some.
