Is 7970 harvested 2304 (36CU) GPU?
I wonder this too, i asked on b3d

lol, lets try this again. MOST of the reviews could hit 1125 which was the most allowed in the CCC. some reviews could not even hit 1100 though. that makes me wonder just how much voltage it would take to get to a whopping 1325.
Are the 6gb rumoured to be released on Jan 9th? Or will they come much later on?

Speaking of rumor, shouldn't the title be tagged as such?
Actually a 6gb video card could come in handy with 3d applications packages where you have huge models with shitloads of high resolution textures. This is one of the reasons why I am contemplating getting a 6gb card. Also the huge video memory might possibly be used to advantage with gpu rendering. Another reason would be that you it could host large data sets for data processing in math apps for gpu processing.
And for gaming as I have mentioned Doom 4 will more than likely be using a modified and updated megatexturing which will eat video memory like a geek would eat free pizza.
Th3y c4n'7 5p34k l337 l4ngu4g3Could have clocked it 2MHz higher and sold it as the 1337 edition. Seems Sapphire missed a golden marketing opportunity.

That is soo darn epic
The Saphire L33T edition, @ 1337mhz
Any chance this will come with a waterblock attached, and not have an air cooler?
Thats probably what the WC is on the second line, but what could RX be on the first one?
Edit - Should have read the second page, looks like it was already discussed...
And I think the 2304 was the original intent by AMD, but they had to settle for 2048 to get it to market. Hence why it is crossed out, and have lower BIOS numbers...
I was wondering if RX was for some type of phase change cooling.
Latest rumors indicate that some CUs on the tahiti pro chip are disabled, in order to get it to market faster. This also means that AMD will be ready for nvidias next offering, as AMD is very likely (99% chance) of releasing a tahiti pro refresh with higher clockspeeds and lower TDP. This is the same thing nvidia did with Fermi and GTX 480, part of the die was disabled until the 580 was released.
Its basically looking like AMD is ready to fight nvidia using nvidias strategy. Much like nvidia did with the Fermi 5xx refresh.
Late last week, we started hearing a rumor considering recently launched Radeon HD 7970. The rumor was based on leaked Sapphire documents that were mentioning insanely high clocks for their upcoming parts, but also specified parts featuring the Tahiti GPU with 2304 cores.
Given that AMD did not deliver die shots of Southern Islands GPU architecture, it wasn’t too hard to see the tech media and consumers spreading like wildfire. AMD did not help the matter by not returning the early calls but in all fairness, it was New Year weekend.
We contacted AMD's representatives such as Mr. Chris Hook and Eric Demers and received a straight answer from the company, represented by Mr. Hook, Senior PR exec:
"There are no hidden cores…"
There you go - unlike Intel that had serious issues with power consumption and heat dissipation on their Sandy Bridge-Extreme processors and had to disable two processing cores and 5MB of L3 cache, or NVIDIA that had 512-cores inside their GF100 (GeForce GTX 480) chip and had to disable 32 processing cores in order to get acceptable yields - AMD has 4.3 billion transistors which pack a 384-bit interface, 2048 processing cores in 32 Compute Units (CU0-CU31) and there is no room for couple of hundred million additional transistors "doing nothing."
I wonder how GCN's double precision performance will compare to Kepler and Fermi. Is AMD planning to artificially limit double precision performance to sell higher end cards? If not, nVIDIA is going to be seriously undercut by a 6GB 7970 with serious double precision performance.
