6970 vs. GTX570

post #1 of 96
Thread Starter 
What's the verdict? All the reviews seem to contradict each other, some with the 6970 leading, others with the GTX570 leading.

Anyways, I know all those reviews are irrelevant now anyways, as drivers have matured since then. Which is the better card now (with current drivers)? What is the expected OC one can get from a GTX570 and 6970?

The 6970 should be faster. In most reviews they are equal but with the recent drivers (11.4 preview), the 6900 cards got a good boost which should increase 6970 performance quite a lot, as it did with my 6950, and there is more to come. Check it out here.

A GTX 570 on stock volts can vary, but most should do around 800Mhz easily. The 6970 however may do 940, or 980.. it depends, but the memory on the 6970s in most cases does 1500+ which gives a nice improvement in performance. Both are good and scale equally depending on how you overclock them and such. Anybody who tells you the 570 is better because it goes higher on the core is an idiot, because while it is true, the memory doesn't give much of a performance improvement as it does for the 6970, so in the end the performance gained will be equal. Likewise, the 6970 wouldn't be superior because it gets to insane memory speeds. However they are about the same in the end.

It all comes down to price, and if the difference is $20 or less, then definately the 6970.

The 6970 shines because of its extra VRAM. With current drivers it surpasses the GTX 570 and is somewhat close to the GTX 580. Here's some benchmarks to show the difference.

For expected OC I really couldn't say since I haven't had either, but I would assume at least 20%.

Hmmm, with the ability to unlock a 6950 to 6970 (with a 96% chance of success http://www.techpowerup.com/articles/...ng/vidcard/159), 6950 is starting to seem really damn good...

The 6970 will overclock much better than an unlocked 6950 though. Take a look at the PCI-E pins. x2-6pins on the 6950 vs 1x6pin & 1x8pin on the 6970.
However, for the price difference, the 6950 is of course the best deal for the money atm.

I've had 3 different 6950s and they can all do 1450+ on memory and 1Ghz fine. Obviously for higher you'd want the 6970, and the memory on the 6970 is rated for 1500Mhz and most can do that or higher. It depends on how much he has to spend.

@OP: The ASUS 6970 DirectCU II should be about the same price and if it is, go for that one. Its by far the best 6970 and overclocks really well. It did 1100 in one review with 1.2v, which is slightly above stock.

Just fyi thd Gtx 570 runs very hot compared to my unlocked 6950. (I had both) Then we have the whole VRM debate with the 570s which makes me iffy about them. If I were you and I wanted nvidia, Id go either a gtx 480 or a 560ti(proven to oc ok). If you want Amd then go for the 6970 or try to find a rev1 6950 and unlock

The 6970 DC2 is the better part of $400, and the 6950 DC2 (which is probably binned lower than the 6970 DC2) is about the same as a regular 6970. When you figure that a 1gb 6970 (unlocked 1gb 6950) can be had for ~$250, it's pretty hard to justify for a few hundred mhz.

On your 6950's, was that OC with stock OEM cooling? Was the 1ghz core something you would run 24/7, or did you need to run the fan so hard that it sapped your sanity?

Can you link this VRM debate thing? The only thing I've heard re: its VRMs is that they need good cooling for good OC'ing

What's the difference between the rev 1 and rev 2 6950s? Is the rev 2 unable to unlock? Or does it have a shortened PCB for cheaper manufacture? How does one tell between the two? Are there rev 1 2gb versions of the card? I was sort of set on 2gb if I went ATI (suck it AMD, I'm oldschool).

The GTX is faster at 1080P/1200P in most cases, 1600P its about even.
That being said, its basically the same performance.

I chose superior drivers/tessellation and PhysX.
I am over stock 580 performance and will go SLi when I need to

Well, 2 of them needed 65% fan speed, one needed 75%. 24/7 yea, but I prefer less noise (and I always game stock) so I don't know how you would feel about that. Not sure about you. You can grab a 6970 for $300 after rebates and $10 off code over at newegg, so if you have the extra $50 to spend then i'd definately recommend it.

A 1GB 6950 is $225 after MIR, which is also pretty good (the sapphire one will have voltage tweak for sure and they are generally good overclockers). It depends how much you can spend but all they are all good choices. It's not 100% validated that 1GB cards will (or will not) unlock, but i did see somebody here unlock their non-reference 6950 (dont know if it was 1gb or 2gb). With the new drivers the 6950 should be about 10% faster on average and future drivers should improve performance. In the end that's the card I recommend though.

Definately faster, especially with these new drivers which really suck.
