Amd releases final r600(x2900) specs

Six weeks from now, the world will get the first retail Radeon X2900 XTX

Late yesterday DailyTech was briefed on the final details for the upcoming R600 retail specifications, just in time for everyone to go on vacation for Chinese New Year.

AMD's guidance claims R600 will feature 700 million transistors. By comparison, the Radeon X1900 series R580 GPU incorporated 384 million transistors into its design; the half-generation before that, R520, only featured 320 million.

As disclosed by DailyTech earlier this year, the GPU features a full 512-bit memory interface with support for GDDR3 and GDDR4. R580 was also similar in this regard as it supported GDDR3 and GDDR4.

On March 30, 2007, AMD will initially debut the R600 as the ATI Radeon X2900 XTX in two separate configurations: one for OEMs and another for retail. The OEM version is the full length 12" card that will appear in high-end systems.

ATI guidance claims the X2900 XTX retail card comes as a two-slot, 9.5" design with a vapor chamber cooler. Vapor chambers are already found on high-end CPU coolers, so it would be no surprise to see such cooling on a high-end GPU either. The OEM version of the card is a 12" layout and features a quiet fan cooler.

1GB of GDDR4 memory is the reference configuration for Radeon X2900 XTX. Memory on the reference X2900 XTX cards was supplied by Samsung.

Approximately one month later, the company will launch the GDDR3 version of the card. This card, dubbed the Radeon X2900 XT, features 512MB of GDDR3 and lower clock frequencies than the X2900 XTX. The X2900 XT is also one of the first Radeons to feature heatpipes on the reference design.

AMD anticipates the target driver for X2900 XT to be Catalyst 8.36. WHQL release of the X2900 XTX drive will appear around the Ides of March.

Radeon X2900 will feature native CrossFire support via an internal bridge interface -- there is no longer a need for the external cable found on the Radeon X1000 series CrossFire. There is no Master card, as was the case with other high-end CrossFire setups. Any Radeon X2900 can act as the Master card.

A much anticipated feature, native HDMI, will appear on all three versions of Radeon X2900.

One 6-pin and one 8-pin (2x4) VGA power connectors are featured on Radeon X2900, but both connectors are also backwards compatible with 6-pin power supply cables.

AMD claims the R600 target schedule will be a hard launch -- availability is expected to be immediate. Board partners will be able to demonstrate R600 at CeBIT 2007 (March 15 - 21), but the only available cards will be reference designs.

Why was there such discrepancy with the board layouts and designs up until now? An ATI insider, who wished to remain nameless, states "The original Quad-Stealth design is what we build the R600 on: GDDR4, full-length and dual-slot cooling. As the silicon further revised, [ATI] took up several alternative designs which eventually included GDDR3 and heatpipes into the specification. The release cards demonstrate the versatility of R600 in each of these unique setups."

Final clock frequencies will likely remain estimates until later this month.

My buddy who owns an 8800 aswell, was basically tripping out cause he just bought the card a month ago and it will be trumped by another card already.

I don't see it that way. My GTS will still play everything on max smoothly, so what if thiers a newer better card. The 8800's are still a beast. Its just getting crazy with these cards now. I don't think the actual technology in games can catch up to the graphic processing power on these card. 8O

All the rest (including Oblivion) are playable at full detail on highend systems.

flight sim x the newest one.

the older ones were more cpu bound but the new is everything bound

Mr. Heck's got a point. Up until the 8800 series, oblivion was a bitch. And I still haven't seen any benchies for fear with soft shadows enabled that show any good FPS (everything else maxed out of course).

and most of the games are miles ahead of the videocards.

"F S X" is the only thing an X6800 with SLI 8800GTX's is scared of.

@sir heck: Well, you more than doubled the number of pixels, so you shouldn't be that surprised.

Really? I always thought games are ahead of videocards. I mean they could make the best of graphics but they have to dim them down so that people would actually be able to play them or else nobody would buy.

I'm wondering. Why does everyone have a userbar? Is it because of me?

PS.
Wusy was probably first to have one here...
