The Test
We are using the same Intel Core 2 Extreme X6800 setup for this article that we've been using over the past couple months. Driver revisions haven't changed since our 7950 GT article, and we will be looking at the same three resolutions: 1280x1024, 1600x1200 and 1920x1440. Here's the breakdown of the hardware used:
| CPU: | Intel Core 2 Extreme X6800 (2.93GHz/4MB) |
| Motherboard: |
Intel D975XBX (LGA-775) ASUS P5NSLI |
| Chipset: |
Intel 975X NVIDIA nForce 570 SLI |
| Chipset Drivers: |
Intel 7.2.2.1007 (Intel) NVIDIA nForce 8.22 |
| Hard Disk: | Seagate 7200.7 160GB SATA |
| Memory: | Corsair XMS2 DDR2-800 4-4-4-12 (1GB x 2) |
| Video Card: | Various |
| Video Drivers: |
ATI Catalyst 6.9 NVIDIA ForceWare 91.47 |
| Desktop Resolution: | 1920 x 1440 - 32-bit @ 60Hz |
| OS: | Windows XP Professional SP2 |
We will also be testing with the same seven games we've employed for the past few reviews. Next month will see an exciting change in our benchmarking lineup as we are preparing new games for the bench right now. Expect to see the latest Battlefield, Splinter Cell, and Company of Heroes make their way into our test suite in the near future. For now, sit back, relax, and enjoy the soothing experience that is benchmark analysis.
There is quite a bit of data in each of these tests, so we'll focus on the sweet-spot performance analysis and leave the rest of the data more for reference than anything else.

Is this a optical shrink to 80nm?Answering this question will put overclocking expectations in line. Generally, optically shrunk cores from TSMC overclock to the about the same as the original or perhaps slightly worse.

Well no as this piepline configuration doesn't exist natively before on the 90nm node. It's a 3 Quad Part, so it's basedon R580 but has 1 Quad Physical removed as well as being shrunk to 80nm. Not to mention Native Crossfire support was added onto the die.Spoelie - Friday, October 20, 2006 - link
Optical shrink, this is 80nm and the original was 90nm. You're normally correct because the first optical shrink usually does not have the same technologies as the proces higher up (low-k and SOI for example, this was the case with 130nm -> 110nm), but I don't think it's the case for this generation. Regardless, haven't seen any overclocking articles on it yet so I'm quite curious.Spoelie - Friday, October 20, 2006 - link
oie, maybe I should add that it's reworked as well, so both actually. Since this core didn't exist before (rv570 and that pipeline configuration), I don't think that they just sliced a part of the core...Zstream - Tuesday, October 17, 2006 - link
Beyond3D reported the spec change a month before anyone received the card. I think you need to do some FAQ checking on your opinions mate.All in all decent review but poor unknowledgeable opinions…

Just because ATI made the spec change public does not mean it is alright to change the specs of a product that has been shipping for 4 months.X1900 GT has been available since May 9 as a 575/1200 part.
The message we want to send isn't that ATI is trying to hide something, its that they shouldn't do the thing in the first place.
No matter how many times a company says it changed the specs of a product, when people search for reviews they're going to see plenty that have been written since May talking about the original X1900 GT.
Naming is already ambiguous enough. I stand by my opinion that having multiple versions of a product with the exact same name is a bad thing.
I'm sorry if I wasn't clear on this in the article. Please let me know if there's anything I can reword to help get my point across.

This is very common. Many vendors in the past have passed off 8500s that run at 250/250 instead of the stock 275/275, and don't label them as such.There are some Asus SKUs that have this same handicap, but I can't recall what models that were.

any word on what the new price for the x1900gt's will be now that the x1950pros are out?or are they being phased out and no price drop is being considered?

You guys are such cheerleaders..For a single card buy why would you get this?
Why would you buy the 1900GT even after the
1900XT 256MB came out?
I got my 1900XT 256MB for $240 shipped..
Except for power consumption it's a much better card.
You get to run Oblivion great with one card.
Two cards is such a scam. More expensive motherboard..power consumption etc.
This is progress? CPU's have evolved..
It's hard to even find a motherboard with 3 PCI slots..
What a scam! Where's my ultra-fast HDTV board for PCI Express?
Seriously..Why buy into SLI/Crossfire? Why not 2 GPU's on one card?
Too late..You all bought into it.
Sorry I am just so sick of the praise for this money-grab of SLI/Crossfire.

Are the power consumption numbers (98W idle, 181W load) for just the graphics card or are they total system power?Thanks in advance,
