AMD announces its long-awaited ATI Radeon HD 2900 XT, seven months after its initial launch date

AMD is prepared to launch its ATI Radeon HD 2000 family tomorrow. The new ATI Radeon HD 2000 family consists of the HD 2400, HD 2600 and HD 2900 graphics processors, formerly known as RV610, RV630 and R600, respectively. Although AMD will announce its ATI Radeon HD 2000 series, only the ATI Radeon HD 2900 XT will have immediate availability. The accompanying ATI Radeon HD 2400 and HD 2600-based products are paper launches.

After months of delays, AMD’s R600 GPU is finally ready for consumer purchase. Only one ATI Radeon HD 2900 model will launch today in XT guise. DailyTech previously pitted the ATI Radeon HD 2900 XT up against NVIDIA’s GeForce 8800 GTS. The ATI Radeon HD 2900 XTX previously benchmarked by DailyTech will not hit retail channels, for now.

AMD’s ATI Radeon HD 2900 XT packs 320 unified stream processors with an estimated 47.5 Gigapixels/sec pixel processing rate. The 320 stream processors are joined by 16 texture units and render backends. AMD claims the 740 MHz ATI Radeon HD 2900 XT delivers 475 GigaFLOPS of processing power in multiply-add, or MADD, calculations.

AMD pairs the 700 million transistors GPU with 512MB of GDDR3 video memory. The 1.65 GHz GDDR3 memory communicates with the GPU via a 512-bit memory interface, delivering 106 GB/sec of bandwidth. The new ATI Radeon HD 2900 XT continues to make do with an 80nm fabrication process to consume approximately 215 watts of power altogether.

Although images have shown the ATI Radeon HD 2900 XT with dual dual-link DVI ports, the card does in fact support HDMI output. An included adapter allows users to experience high-definition video and 5.1 surround sound audio via HDMI output. Also bundled with the ATI Radeon HD 2900 XT are keys for Valve’s upcoming Half Life 2: Episode Two and Team Fortress 2. The keys allow owners to download the games, when released, over STEAM.

Taking on NVIDIA’s recently launched GeForce 8600 family is the new ATI Radeon HD 2600 series. AMD plans to paper launch the ATI Radeon HD 2600 in PRO and XT guises. The ATI Radeon HD 2600 series features 120 stream processors. The GPU is clocked anywhere between 600 to 800 MHz depending on flavor. AMD backs the 120 stream processors with eight texture units and four render backends.

The amount of processing power brings the ATI Radeon HD 2600 GPU transistor count to 390 million. Nevertheless, the ATI Radeon HD 2600 is manufactured on a 65nm process. AMD rates power consumption at approximately 45 watts.

AMD pairs the ATI Radeon HD 2600 GPU with GDDR4, GDDR3 or DDR2 memory. Manufacturers can equip cards with 256MB of video memory clocked anywhere between 800 MHz to 2.2 GHz, on a 128-bit memory interface. ATI Radeon HD 2600-based cards will also support HDMI audio and video output via adapter.

At the bottom of the new ATI Radeon 2000-series lineup is the ATI Radeon HD 2400 series with PRO and XT models. The new ATI Radeon HD 2400 features 40 stream processors with four texture units and render backends.  GPU clocks vary between 525 MHz to 700 MHz.

The ATI Radeon HD 2400 series features less than half the transistors as the HD 2600 – 180 million. AMD has the ATI Radeon HD 2400 series manufactured on the same 65nm process as the HD 2600. Power consumption of the ATI Radeon HD 2400 hovers around 25 watts.

Add-in board manufacturers are free to equip ATI Radeon HD 2400 series graphics cards with GDDR3 or DDR2 memory. The GPU supports 128MB or 256MB memory configurations on a 64-bit memory interface. Memory clock can vary from 800 MHz to 1.6 GHz depending on model. Expect ATI Radeon HD 2400 series graphics cards to support HDMI audio and video output via a DVI to HDMI adapter.

Despite an announcement for the complete ATI Radeon HD 2000 series, the ATI Radeon HD 2900 XT will be the only card available for purchase tomorrow. The ATI Radeon HD 2600 and HD 2400 series will hit retail in late June 2007 with an accompanying benchmark NDA lift.

Expect to pay $399 for an ATI Radeon HD 2900 XT tomorrow from the usual add-in board partners including Diamond Multimedia, HIS, PowerColor and Sapphire Technology. AMD expects to target the ATI Radeon HD 2600 series towards the $99 to $199 market segment and ATI Radeon HD 2400 series towards the less than $99 segment.

The Bottom Line

“A day late and a dollar short.” Cliché but accurate. The Radeon HD 2900 XT is late to the party and unfortunately is bringing with it performance that cannot compete. The GeForce 8800 GTS 640 MB is $50 cheaper, performs better, and draws a lot less power than the 2900 XT.

This is as good as it is going to get for a while from ATI. The GeForce 8800 GTX will still dominate at the high end of the video card market. Of course we do not know about DX10 games yet, and there is no way to make any predictions how that comparison will turn out. As it stands right now the Radeon HD 2900 XT, in our opinion, is a flop . ATI needs to get its act together quickly. It needs to push out the mainstream cards soon and it needs to deliver a high end card that can actually compete at the high end of the market.

hardocp has been a little too nvidia minded lately, both in their wordings and their tests. I remember a lot of negative backlash on the 8600gt/s test that they did not adress or explain.

HardOCP has been extremely nvidia-biased ever since the delay of the X1800, and the delay of the HD 2900 hasn't helped anything at all.

You've gotta be kidding me... Do you think that ATI deserves any praise whatsoever since the X1800? The X1800 was a failure, X1900 series performed better, yet nVidia still had a better solution and multi GPU implementation (dongle anyone?). ATI's chipsets have not been as competitive as Nvidia & Intel offerings and now ATI is 7 months late with a power hungry lame duck?

I'm sorry, but maybe that bias is the reality of the high-end GPU landscape. ATI is a non-player at his point in time in the high-end market.

We're already hearing "just wait for R700!", and I for one am finished waiting for ATI to execute. It appears that my 9700Pro will be the last ATI card that I will own for some time to come...
