AMD Cayman, Antilles Specifications Surface
At last, specifications of AMD's elusive Radeon HD 6970 and Radeon HD 6990 graphics accelerators made it to the internet, with slides exposing details such as stream processor count. The Radeon HD 6970 is based on a new 40 nm GPU by AMD, codenamed "Cayman". The dual-GPU accelerator being designed using two Cayman GPUs is codenamed "Antilles", and carries the product name Radeon HD 6990.
Cayman packs 1920 stream processors, spread across 30 SIMD engines, indicating the 4D stream processor architecture, generating single-precision computational power of 3 TFLOPs. It packs 96 TMUs, 128 Z/Stencil ROPs, and 32 color ROPs. Its memory bandwidth of 160 GB/s indicates that it uses a 256-bit wide GDDR5 memory interface. The memory amount, however, seems to have been doubled to 2 GB on the Radeon HD 6970. Antilles uses two of these Cayman GPUs, combined computational power of 6 TFLOPs, a total of 3840 stream processors, total memory bandwidth of 307.2 GB/s, a total of 4 GB of memory, load and idle board power ratings at 300W and 30W, respectively.

If this card is over 300GB/s (307GB/s) memory bandwidth, it will be beastly as the 5970 Dual GPU has 256GB/s
The 6970 single GPU specs below.

The HD 6970 will beat the GTX 580 from what i read out of the specs.
A more interessting thing about who hold the crown of speed with graphic cards is the battle between the dual GPU monsters. This time NVIDIA will not let AMD hold the crown, the GTX 590 is ready to come, it consumpts around 400 Watts

from what i heard it comes around same time as the Antilles 6990

I wish they would both hurry up and release these new cards, I want a GTX 590 now!
Seriously tho, there are a few cards out there capable of running any DX11 game pretty much maxed out.
I have a 30" screen with a 5970 (256GB/s) and run BC2 maxed out at 2650x1600 and with 4x AA i can see slight slow down while close to a lot of large explosions and with 2x i get over 60fps, which is a very sweet spot.
which is very impressive really. Saying that, these upper end cards and new cards are priced at over £400 each they blinkin well shud run anything and without any issues at all.
If you can afford them, you won't go wrong with either new dual GPU cards, 590 or the 6990 but make sure if you do, you're not wasting them running them on a screen less than 30"
If this is the case, then go for the 6970 or the 480 (or cards around 128 to 160GB/s bandwidth) and save your money for DX12 cards later ;)
IS that a betamax? Is that a VHS? Noooo its an ATI 6990 !
Soon be ready for release. 6990 pictured here... http://forums.techpowerup.com/showthread.php?t=139043
A few days earlier, AMD's Rick Bergman displayed the company's newest graphics card that seeks to extend the performance leadership currently held by Radeon HD 5970. The dual-GPU AMD Radeon HD 6990, codenamed "Antilles", makes use of two 40 nm "Cayman" GPU, which powers the single-GPU HD 6950 and HD 6970. The core configuration of Cayman in Antilles is not known. The card itself keeps up with the product styling that all Radeon HD 6000 series carry, it's about as long as the HD 5970.

I also thought, that he was holding an VHS in his hand.
Back to the future eh? :rofl:

Me want one. :butcher: please buy one for me. valentine`s coming soon :D
gunter- the 590 will probably beat the 6990
but do you know what the power draw is going to be?? I havnt seen any spec's
I know they have made (some) improvements with the 500 series but is a dual GPU card going to need an extra PSU lol
also any idea of the pricing stratagy... ie is it going to be cheaper (and more prowerful) to source 2 470's and SLi them... as 2 460's are edging on 580 performance..... (obviously without the extra goodies the 500 series come with)
Not sure this is an early estimate. 300gb/s for the 590?
Memory Bandwidth -
307.2 GB/s for the 6990 (dual)
300+ GB/s for the 590 (dual)
256 GB/s for the 5970 (dual)
192 GB/s for the 580 (single)
160 GB/s for the 6970 (single)
152 GB/s for the 570 (single)
The 590 is 2x 570's which will bring us to around 300 GB/s just like the 6990, I really want Nvidia to do well with this Fermi
These 2 cards will be very close in performance and will obviously outperform each other in different games, In any case, pretty much all above gfx cards will max out any DX11 game (like BC2) on a 24" monitor at 1920x1200
so its all according to how much £££'s you wanna waste and how big ur screen is. ;)
Yes dual 580's will be better, with extra cost and power consumption too :)

So, if I have An Ati 5850, it is better for me to buy another one and cross fire them ?
then buying A new 6*** series ?
also I have the Cooler master Silent pro 600W ( http://www.coolermaster.com/product.php?product_id=4199&category_id=2384 ) will this be sufficient for A crossfire configuration ?
or should I buy A better one?
Yes, as the 5970 is in fact 2x 5850's at 128gb/s you would in effect have the same as me.. a 5970 ;)
128x2 = 256gb/s
ahhhh but I said 480.... ( I actually meant 470 see edit above)
which I could pick up for £175-£200 each.... which means If the 590 is over £400 could essentially do better getting two 470's
(obviuously ignoring the fact I might have to buy a new PSU, even mine might be pushed with that set up..... mabye not lol)
EDIT---- I will redefine my question
Zotac 1Gb 460 SE, £125 from scan..... Memory bandwidth ~ 115.2Gb/sec
PNY 1536Mb 580, £383.50 from scan..Memory bandwidth ~ 192Gb/sec
so 2 x 460's would be 230Gb/sec..... ish.... and £133 cheaper.....
BTW, that Zotac 460 is PC Formats best buy (midrange card) last month..... mostly beacuse of price... but performance aint bad either

The Radeon HD 6990 uses two 40 nm Cayman GPUs, it packs a total of 3072 stream processors, and 4096 MB of memory between the two GPU systems.
It also features a new kind of display output that consists of one dual-link DVI and four mini-DP 1.2. Power is drawn in from one 6-pin and an 8-pin PCIe connector.
The card can pair with another of its kind for 4-GPU CrossFireX. It is expected to be released a little later in this quarter.
In terms of performance, if previous leaks are legitimate, the graphics card will integrate 3840 stream processors and have 4GB of GDDR5 memory clocked at 4.80GHz.
That’s a significant leap from the previous-generation Radeon HD 5970's 3,200 stream processors and 2GB of RAM. Pricing info is not yet known but it's likely
the Radeon HD 6990 will go over $500, which is the price tag of Nvidia's flagship card, the single-GPU GeForce GTX 580.
The 590 is 2x 570's which will bring us to around 300 GB/s just like the 6990, I really want Nvidia to do well with this Fermi
Yes dual 580's will be better, with extra cost and power consumption too :)
Correction :
The GeForce GTX 590 will pack two GF110 graphics processors offering a total of 1024 CUDA cores, 3027MB of GDDR5 memory, dual 384-bit memory buses, 128 texture units, and 96 ROPs. That effectively doubles the specifications of Nvidia's single-GF110 GeForce GTX 580.
The 590 is apparently due this month (february 2011) at a cost of around $700, this will likely be taking the GFX crown :)

You can pre-order the 6990 for a lil over 700 euro's lolz € 715 (about US $1,000).
I'll have 2 please. Or one if someone will be so kind :)

It does look like they have since removed the price today tho.
This 6990 was launched today and will set u back around 700 euro's lol
This is the fastest single card out there, at least until the 590 comes.
