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.

Here is an interesting part of VR-Zone conclusion:

quote:
As said before, I had results from both the Catalyst 8.36 and Catalyst 8.37 Drivers. How did performance improve between this small driver jump of 0.01 version?


quote:
Taking a setting at 1600x1200 with 16xAF, I saw a major increase in performance, particularly Company Of Heroes and Quake 4. Performance went up by 11% on COH and 42% on Quake 4! This shows that the drivers is still very raw on this card , with just a minor driver revision boosting up performance that much, it gives us quite a lot of hope for a fair bit of improvement to come. Let's hope for that!


quote:
In many non Anti-Aliasing, High Definition game settings, you have seen the X2900XT push ahead of the performance of it's closest competitor, the GeForce 8800GTS 640MB, sometimes by quite a large margin, sometimes falling behind or ahead by a small percentage. In a select few games, the GTS is slightly faster, and vice versa. When Anti-Aliasing is turned on, the X2900XT showed that it carries it off with great efficiency in games that the drivers are optimized for, performing significantly better than the GTS; while the AA efficiency is piss-poor in some games due to the raw driver which has not fully blossomed to take advantage of ATi's new GPU technology. Just take a look at how performance has boosted from Drivers 8.36 to 8.37, that shows the potential in performance growth... a whole lot of it to reap.


I don't know about Quake4 but the performance boost for Company of heroes in X1000 class cards exist since catalyst 7.1 or maybe 7.2. Even though the new generation are complicated products with DX10, Audio and maybe physics handling, but immature drivers after 6-7 months delay is not acceptable.

8.39 got released to reviewers yesterday.

Is there any indication on how it performs compared to the previous releases?

That's a hell of a conclusion to pull. What I suspect happened (this happened with us until we figured it out) was that you had to put two cards into Crossfire first, then back down to single-card. Doing so would increase single card operation by like 20%. I'm guessing the 8.37 addressed this.

Sorry but I am a bit confused here. Are you implying that prior to 8.37, in a two cards setup, even if you choose to test a single card, still the second card will influence the test? or you are saying that the single card test was 20% lower than what it should have been and adding another card corrected the mistake.

Correct, you had to go to two cards, then back down to one card. This same problem used to happen a lot in the original Crossfire days.

nvidia never had nor seems to have updated drivers for year+ hold products. ....
