The AMD HD 2000 Series Lineup
The announcement today includes a top-to-bottom lineup of DX10 class hardware including four mobile parts (with one additional DX9 mobile part sharing the HD 2000 series naming) and five desktop parts. While all of this hardware is being made public, we've only got one piece of hardware to bring to the table today: the R600 based Radeon HD 2900 XT.
Performance on all other R6xx parts won't be available until "late June", but we can still talk about what these parts will be when they finally make it to market. On the desktop, in addition to the HD 2900 XT, we will see the Radeon HD 2400 Pro and XT in the "value" segment, with the HD 2600 Pro and XT providing good mainstream-to-midrange gaming performance.

There is currently no add-in retail hardware planned that tops the HD 2900 XT, but we are hearing rumors that faster parts may be available through OEMs only. This is unconfirmed at present, so take it with a grain of salt. Let's take a look at a break down of what we do know we'll be getting:
| AMD R6xx Hardware | ||||||||
| SPs | RBEs | Core Clock | TMUs | DDR Rate | Bus Width | Memory Size | Price | |
| HD 2900 XT | 320 | 16 | 740MHz | 16 | 825MHz | 512bit | 512MB | $399 |
| HD 2600 | 120 | 4 | 600 - 800MHz | 8 | 400 - 1100MHz | 128bit | 256MB | $99 - $199 |
| HD 2400 | 40 | 4 | 525 - 700MHz | 4 | 400 - 800MHz | 64bit | 128MB / 256MB | <$99 |
It's harder to pin down all the specs of the mobile parts, as all the clock speeds (and sometimes bus width) can change depending on the TDP envelope a notebook maker is working with. While we aren't certain, our best guess is that mobile parts named similarly to desktop parts will have the same internal configuration of SPs, texture units, and render back ends. The exception here is the Mobility Radeon HD 2300, which is a DX9 part based on R5xx hardware.
While 2400 and 2600 standard and XT versions will exist in the mobile space, there are currently no plans for a high end mobile part. This is very likely due to the high power draw and low performance per watt we see with AMD's 80nm R600. We don't expect to see a higher performance mobile part until AMD can get the power consumption of its higher end hardware down (likely with a process shrink).
Just for comparison, let's take a look at what NVIDIA is currently offering as well. Here's a table of all the G8x based parts on the market.
| NVIDIA G8x Hardware | ||||||||
| SPs | ROPs | Core Clock | Shader Clock | DDR Rate | Bus Width | Memory Size | Price | |
| 8800 Ultra | 128 | 24 | 612MHz | 1.5GHz | 2.16GHz | 384bit | 768MB | $830+ |
| 8800 GTX | 128 | 24 | 576MHz | 1.35GHz | 1.8GHz | 384bit | 768MB | $600 - $650 |
| 8800 GTS | 96 | 20 | 513MHz | 1.19GHz | 1.6GHz | 320bit | 640MB | $400 - $450 |
| 8800 GTS 320MB | 96 | 20 | 513MHz | 1.19GHz | 1.6GHz | 320bit | 320MB | $300 - $350 |
| 8600 GTS | 32 | 8 | 675MHz | 1.45GHz | 2GHz | 128bit | 256MB | $200 - $230 |
| 8600 GT | 32 | 8 | 540MHz | 1.19GHz | 1.4GHz | 128bit | 256MB | $150 - $160 |
| 8500 GT | 16 | 4 | 450MHz | 900MHz | 800MHz | 128bit | 256MB / 512MB | $89 - $129 |

That's obviously BS. This IS their high end part, it just doesn't perform as well as nVidia's high end part, so it is priced accordingly.poohbear - Monday, May 14, 2007 - link
sweet review though! thanks for including all the important and pertinent cards in your roundup (the 8800gts 320mb inparticular). also love how neutral Anand is in their reviews, unlike some other sites.:pCreig - Monday, May 14, 2007 - link
The R600 is finally here. I'm sure the overall performance is not what AMD was hoping for. Nobody ever shoots to have their newest product be the 2nd best. But pricing it at $399 and including a very nice game bundle will make the HD 2900 XT a VERY worthwhile purchase. I also have the feeling that there is a significant amount of performance increase to be realized through future driver releases ala X1800XT.shady28 - Tuesday, May 15, 2007 - link
Nvidia has gone over the cliff on pricing.
I know of no one personally who has an 88xx series card. I know one who recently picked up an 8600 of some kind, that's it. I have the best GPU of anyone I know.
It's a real shame that there is so much focus on graphics cards that virtually no one buys. These are niche products folks - yet 'who is best' seems to be totally dependent on these niche products. That's patently ridiculous.
It's like saying, since IBM makes the fastest computers in the world (they do), they're the best and you should be buying IBM (or now, lenovo) laptops and desktops.
No one ever said that sort of thing because it's patently ridiculous. Why do people say it now for graphics cards? The fact that they do says a lot about the mentality of sites like AT.

We don't say what you are implying, and we are also very upset with some of NVIDIA's pricing (specifically the 8800 ultra)the 8800 gts 320mb is one of the best values for your money anywhere and isn't crazy expensive -- it's actually the card I'd recommend to anyone who cares about graphics in games and wants good quality and performance at 1600x1200.
I would never tell anyone to buy an 8600 gts because nvidia has the fastest high end card. In fact, in this article, I hope I made it clear that AMD has the opportunity to capitalize on the huge performance gap nvidia left between the 8600 and 8800 series ... If AMD builds a part that performs in this range is priced competitively, they'll have our recommendation in a flash.
Recommending parts based on value at each price or performance segment is something we take pride in and will always do, no matter who has the absolute fastest hardware out there.
The reason our focus was on AMD's fastest part is because they haven't given us any other hardware to test. We will absolutely be talking a lot and in much depth about midrange and budget hardware when AMD makes these parts available to us.

$400 is a lot of money. Not terribly long ago the highest end GPU available didn't cost more than $400. Now they hit $750 so you start to think $400 sounds cheap. It's really not. It's a heck of a lot of money for one piece of hardware. You can put together a 650i SLI rig with 2GB of DDR2 6400 and an E4400 for that much money. I know because I just did that. I kept my 7900GT from my old rig because I wanted to see how R600 did before purchasing an 8800GTS 640MB. Now that we've seen initial results I will wait to see how R600 does with more mature drivers and also wait to see the 640MB GTS price come down even more in the meantime.vijay333 - Monday, May 14, 2007 - link

Yes, a spade was a shovel long before muslims enslaved europeans to do hard labor in north africa and europeans enslaved africans to do hard labor in the 'new world'.vijay333 - Monday, May 14, 2007 - link
whoops...replied to the wrong one.rADo2 - Monday, May 14, 2007 - link
It is not 2nd best (after 8800ULTRA), not 3rd best (after 8800GTX), not 4th best (after 8800GTX-640), but 5th best (after 8800GTS-320), or even worse ;)Bad performance with AA turned on (everybody turns on AA), huge power consumption, late to the market.
A definitive failure.
