AMD HD6990 Preview – Photos and Screenshots!

GEEKGASM

I was wondering what are the parts surrounded? Is the black squares the memory module (AKA ram?)

I only see 8 memory modules (4 per GPU I bet). My 5870 has also 8 but for only one GPU and it just has 1Gb :confused:

This beast shoulda have at least 4Gb to compete with the 5970 6 eyefinity version.

As you can see, there's also 8 memory modules per GPU in the 5970!

I would assume (very uneducated here), but they [Amd] probably changed to a more dense ram, or put some on the back side... Like SDRAM, it's possible to have more or less dense memory banks. The more dense all fit on one side vs. the less dense have to go on both sides to give the same total space.

Is there any advantage having it dense beside space save? In my mind, dense = expensive. Also, I checked the 6970 PCB and it looks like it is build as the 5870 in term of memory module. Quite intrigued with that stuff.

"March 8 Launch Date for Radeon HD 6990
The the consumer graphics industry is about to see yet another round of competition between top market players AMD and NVIDIA in March, with reports suggesting that the red team (AMD) has chosen March 8 as the launch date of its Radeon HD 6990 graphics card. NVIDIA's response, the GeForce GTX 590 is slated for sometime later in March, as well. AMD is said to be finalizing the SKU, and it should be launched by partners on the 8th of next month. The Radeon HD 6990 is a dual-GPU "CrossFire on a stick" solution, in which two AMD Cayman GPUs with 2 GB of memory each, work in tandem."

I am no expert but this is what I think each thing you circled is:

Yellow box: There looks like they'd be the power circuitry for the memory modules.

Purple box: The purple box and the yellow box below it are probably the power circuitry for the GPU cores.

Red box: I think that controls communications between each 'GPU section', I guess you could call it a crossfire chip, except it is likely higher bandwidth and lower latency.

Green box: No clue, other than it looks like it might belong to the memory power circuitry above it.

These are all just what I think, I don't actually know. I could possibly have the memory and GPU core power circuits mixed up too. There is likely RAM modules on the back, with AMD pushing 5x1 eyefinity as a major feature of this card it would be hard to believe them having anything less than 2GB per GPU section.
