Radeon HD7970 specs leaked. 3.5 Teraflops, 3GB vRAM

Update: 5:35, added a few points.

If the convincing-looking leaked slides are to be believed, the upcoming AMD Radeon HD 7970 card is now naked before us with all its measurements laid to bare. While there still is nothing official as the embargo is not up yet, rest assured that at some point the full story will flood to the surface. What can be said is that if this slide is true, the 7970 looks to be a real beast of a card.

The supposed reference specifications of the 7970… or are they?

As you can tell from the heavily watermarked slide, AMD claims 3.5 TFLOPs of computing power from their 2048 stream processing units clocked at 925 MHz. Contrast this against the AMD’s assertion of 2.7 TFLOPs from the Radeon 6970’s 1536 stream processors and a core clock of 880MHz; while it is not an apples-to-apples comparison, it is a healthy buff to AMD’s portfolio. Also relevant, is a more recent slide claiming much-increased performance during tesselation which NVIDIA typically has maintained a healthy lead over AMD with.

Possibly the most major point from the table is the power consumption: less than 3 Watts during idle. To give a bit of... pc perspective...: HardOCP measured the idle power consumption of the 6970 to be 24 Watts and the NVIDIA GTX 580 at 41 Watts. We are talking about an 88% decrease in idle power draw compared to AMD’s last generation’s single GPU powerhouse. It makes me wonder: how will this affect mobility graphics? According to OBR-Hardware, their slide is somewhat out-of-date; the expected peak is 200W give or take for the card on load, though I am sure that will vary depending on which brand of card you purchase.

don't trust anything from OBR-Hardware

and besides he doesn't know how to spell...

"embago" is just the Bostonian pronunciation of embargo... :)

AMD's HD6970 and HD6950 2GB reference card model is a huge
success and up to now its still AMD's one of the top
selling video cards due to its hi performance, overclock-
ability and price SPECIALLY the reference HD6950 2GB model
due to its highly beneficial unloackable features.

I hope in the up coming release of the HD7900 hi end
segment models particularly the HD7950 reference card AMD
would still offer highly beneficial unloackable features
that can be found in their HD6950 model.

I dont know how nVidia would react to that but it seems
they are getting a lot of bad karma with their hypocrisy
and bad publicity whenever they say something bad about the
success of their competitors. I just dont know if they learn
something from the bad karma they are getting...

If 3W idle is true it's pretty amazing.

Being a Nvidea apologist even I give my hats off to AMD on this.

I really doubt the new cards will only have 32 ROPS. Thats what the 5800 and 6900's had. It's probably 48 or 64.

I don't care one bit what AMD puts in their hardware until they show gamers that they take drivers seriously. My 6970 trifire is quite likely the last AMD graphics setup for quite a while.
