NVIDIA's GeForce GTX 580: Fermi Refined
by Ryan Smith on November 9, 2010 9:00 AM ESTDIRT 2
Codemasters’ 2009 off-road racing game continues its reign as the token racer in our benchmark suite. As the first DX11 racer, DIRT 2 makes pretty thorough use of the DX11’s tessellation abilities, not to mention still being the best looking racer we have ever seen.
NVIDIA has in the past and continues to do rather well in DIRT 2, an amusing outcome given that this was an AMD promoted game. The GTX 580 is not only over 20% faster over the GTX 480, but enjoys a small lead over even the 5970, falling to only the 6870 CF. Not that it’s hard to do well here; even the GTX 480 can almost hit 60fps at 2560.

I would have called them the 6750/6770 personally... Or at the very least the 6830/6850.There were also some architectural changes in the GTX 580 as well.

Whats real and whats not real for you?6850 and 6870 are essentially more shaders, rops and higher clocks with few architectural improvements.
It will be same for the 6900 series.
GTX 580 again is same as the above, few architectural improvements, higher shaders, textures and clocks.
Credit must be given where its due and even though this was supposed to be the 480, its still a great product by its own, its faster, cooler, quieter and less power hungry.

Umm, 6850 and 6870 are DECREASES on all but ROPs and Clocks. The architecture is only similar and very much evolutionary:numbers are: Universal Shader : Texture Mapping Unit : Render Output unit.
5850: 1440:72:32
6850: 960:48:32
5870: 1600:80:32
6870: 1120:56:32
So, 5-10% slower and 33% component shrink, which is to say ~1.4x perf increase per shader. So a full blown (6970) NI at an assumed 1600 shaders like the previous gen would be the rough equivalent of a 2400 shader evergreen when it comes to raw performance, so 1.4 to 1.5 times faster. It can be safely assumed that the shader performance will be higher than 2 5830s in CFX. 2 5830s are about 30% faster than a GTX 580.
That is theoretical performance based on a lot of assumptions and Ideal drivers. My point is NI is not a ground up redesign but it is a vastly superior and vastly different architecture to Evergreen.

I can't wait to see a comparison with the 6970. I don't know which will win but it will help me decide which to get - I'm still using a 4870 so I'm ready for something new!The other thing that will help me decide is card options. The 4870 had some very nice "pre-silenced" modified cards right after release. The 6870 already has some "pre-silenced" cards on the market. The factory standard 580 is pretty loud although it is quieter than the 480 by far. I'm hoping there will be some modified 580's on the market with much quieter but at least as effective cooling solutions.

This is a much better effort than GTX480.Cooler,quieter and faster.
AMD will have a tough fight on their hands with Cayman XT versus this new part.

Can't wait for a price war, something that seemed to be missing with Fermi and the 5xxx series.Sihastru - Tuesday, November 9, 2010 - link
Let's hope so. This way both fanbois camps will win when it comes to how much lighter their wallets will be after their purchase (in some cases their parents wallets - only children act like fanbois).B3an - Wednesday, November 10, 2010 - link
I -wish- only children acted like fanboys. The fact is that a lot of these guys are well into there 20's and 30's.They really are pathetic people.

Well not that it was hard to beat 480 ... that part was not ready for prime time in the first place.dragonsqrrl - Wednesday, March 18, 2015 - link
...lol, facepalm.
