AMD ATI Radeon HD 2000 Series.
Featuring AMD ATi Radeon HD 2900 XT - A closer look into the cat's eye.
Hey everybody, and welcome to the Radeon HD 2000 Series article. Oh my gosh ... Have we all been waiting for this release a long time, or what? I mean initially we (the press) expected this release late last year already. And due to a complexity of issues (AMD and ATI merger), likely fabrication issues and a shift in fabrication process things got delayed; massively. So right now it's April 25th and today 175 press-members are returning from a long technical briefing in Tunisia and I can happily report to you that AMD has now released the ATI Radeon HD 2000 series of product... well, sort of.
What we'll be doing today is take a look at their new high-end product. As we speak, AMD is launching no less than five desktop graphics cards, but it is however not a hard launch. Worldwide you'll only see the one product released and available based on a 80nm fabrication process; the Radeon HD 2900 XT, a product that is going to be discussed and has been discussed a lot for sure.
So there are four other products as well. ATI is also launching an all new Radeon 2400 and 2600 series (low- and mid-range). These products will be based on the newer 65nm fabrication production process.
Let's have a brief overview of the five new graphics cards and on the next page we'll go a little deeper into the silicon that is Radeon HD 2000.
* Radeon HD 2900 XT
* Radeon HD 2600 XT
* Radeon HD 2600 Pro
* Radeon HD 2400 XT
* Radeon HD 2400 Pro
Obviously for all products, we are talking about the next-gen product series here and that means 100% DirectX 10 compatible products, so you'll understand that we'll also talk a little about DX10, the Unified Shader Architecture with these lovely stream processors; a new function on the 2000 Series called Tessellation and last but not least; Avivo HD.
So we'll go rather in-depth today, yet bear in mind that we'll only test and thus benchmark the new Radeon HD 2900 XT graphics card. Now earlier on in the introduction I already told you guys that this is going to be a much discussed product. Why? As everybody expected it to be the new high-end product that would annihilate NVIDIA's excellent GeForce 8800 GTX series. That's not the case. You guys clearly have seen rumours, leaked benchmarks and what not. The HD 2900 XT as we'll show is a really fine piece of hardware but performance wise it sits among the GeForce 8800 GTS cards; if that gives you a better idea. The more interesting thing is it'll be a high-end product at a very interesting price-level. 399 USD. I've talked to a couple of board partners already, and here in Europe this red goblin is selling for 350 EUR !
That really doesn't sound bad, eh? AMD-ATI will take it a step further as all HD X2900 XT boards will be HDMI/HDCP ready, have Avivo HD and will be shipped with three full free games: Half-life2: Episode 2; Team Fortress 2 and Portal. These games are included as coupon (code) and you must download it yourself through Valve's steam. But yeah... great stuff.
Well; let's not get ahead of things ... We have a review to show you. Next page please !

Okay then, let's get started. We are starting off today with a quick overview of the actual cards announced. Although this day is all about the Radeon HD 2900 XT, there are four other cards announced as well. You will not see results of these cards before the 1st of July though. So that makes the 2400 and 2600 series a paper launch for now. Let's have a quick peek at them, shall we?
So basically we see three new product series:
* ATI Radeon HD 2400; a value series
* ATI Radeon HD 2600; mainstream performance segment
* ATI Radeon HD 2900; enthusiast segment
We'll focus on the 2400 and 2600 series in this page. Some keywords here: All the products are DX10 compatible, the 2400/2600 series is made on the all new 65nm fabrication process.
Under codename (ASIC) RV630, ATI developed the Radeon HD 2600 and it'll come in two (Pro and XT) models. The value-targeted RV610-based products will carry the ATI Radeon HD 2400 name with two models; Pro and XT again.
RV610 and RV630 support PCIe 2.0 for increased bandwidth. Native support for CrossFire remains, as with current ATI Radeon X1650 XT and X1950 Pro products. Compared to the R600 (HD 2900 XT), AMD is manufacturing RV610 and RV630 on a 65nm manufacturing process as it's on a quest for low-power consumption. Expect RV610 products to consume around 25 to 35-watts. RV630 requires more power at around 75 to 128-watts.
Radeon HD 2400 Pro & XT
HD 2400 will be the cheap DirectX 10 compatible product. It'll also include ATI Avivo HD technology for HD video playback, and get this: It has built in audio which it can transmit toward your HDMI connector. Basically this is a new function on the entire HD 2000 series.
The graphics core itself has 180 transistors which lead towards 40 Stream (unified shader) processors inside that core. There will be a Pro and XT version of these cards and clock speeds will respectively be clocked at 525 / 700 MHz on the core. For all cards we can tell you that the shader domain runs at the same speed as the core. We tried to unlock this but it's a no-go.
Memory wise it can't get any cheaper. It's 64-bit memory and these cards will come in 128/256MB GDDR 2 configurations, and some board partners can opt for 256MB GDDR3. The Pro will have its memory clocked at 400 MHz where the XT will have a 800 MHz (x2) memory clock. Prices of these two product will remain below 99 USD.

The HD2600 is probably what you guys will buy the most. It's again a fully DX 10 ready product and can do everything the 2400 series can, yet a tad better and faster. 1080P HD decoding? Not an issue. We see the Avivo HD technology for hardware HD video processing with 5.1 audio over HDMI. We'll explain this a bit better in the coming pages. Here's also where the Crossfire fun starts. Have a look at some photos and you'll see the new recently introduced Crossfire connectors (bridged just like NVIDIA's SLI connector). You insert two of these cards in a compatible mainboard, apply the two Crossfire bridges, enable it in the Catalyst driver and you are home-free.
The Radeon HD 2600 series will again be released in two fold, a Pro and an XT version. The GPU core has 390 million transistors; which is a friggin lot for a mid-range product. We see a good number of shader processors; 120 Stream Processing Units. And despite not one member of the press physically had his hands on one, I think the XT can be very interesting. Clock speeds will be high, very high. Expect the Pro to be clocked at 600 MHz and that XT at an amazing 800 MHz. Now among board-partners and models this will vary a little. But again ... 800 MHz for a mainstream graphics card with such a large number of transistors is an all new record by itself.

Radeon HD 2600 Pro
The memory then. I was really hoping to see AMD be the first to go for a 256-bit wide memory bus, but unfortunately just like the competition they are sticking to 128-bit. Configurations will differ, but you'll see 256Mb models based on DDR2, GDDR3 and even GDDR4 memory. That memory will be clocked at roughly 400 MHz for the Pro up-to 1100 MHz for the XT models. Talk about a difference. I tell you, that XT is going to rock. Prices for the Pro will likely be set at a 99-129 USD pricetag with the XT somewhere at 179-199 USD.
