It looks like AMD's claims of HD 7970's extreme overclocking capabilities weren't the usual PR hoopla. A confidential company document revealing the non-reference models Sapphire has in the works, got leaked to the web, and it is a bundle of surprises. To begin with, Sapphire plans no less than six non-reference Radeon HD 7970 models apart from the vanilla AMD reference design card. Among these, the top-of-the-line cards are codenamed "Atomic RX" and "Atomic WC". One can guess that the "RX" is an air-cooled card, and the "WC" a water-cooled one. It packs blistering clock speeds of 1335 MHz core, with 5735 MHz (1433 MHz actual) memory.

:eek: Holy crap that's fast, the 1335 MHZ core speed should put it well past the 6990 and 590 at least at high res going by the overclock results i have seen.

Only moments ago i was mentioning wanting 1.1 GHZ core on a 7970 but i will happily pay for a guaranteed 1335 MHz core.

I wonder how far these things can be pushed by advance over clockers ....
i expect to see 2 GHz+ otherwise i shall be unimpressed by them and their boiling gasses :laugh:

I think those of us with crazy high end air cooling or decent air cooling could for for a full 50% over clock lol

Meh just comes with a block, cheaper to buy a regular one and buy the block yourself :toast:


The air cooled one does 1335 mhz as well apparently :laugh:

If we look at the data Available

at 1920x1200

with 1335mhz core that is a 31% overclock taking W1zzards overclock results and extrapolating the data that would be a 29% performance boost

essentially 15% oc w1zz saw a 14% performance bump double those numbers = 31% 925 / 1335 = .69 x 100 = 31% so if 15% oc is 14% performance 30% would be 28 and 31 = 29%

this should result in around a 5-6% performance boost OVER the HD 6990 / GTX 590

It also results in the HD 7970 being a comfortable 40% faster then a GTX 580

rough estimation

I don't think the Atomic Ones are gonna be great overclockers as we saw with the 4890s which were factory clocked to 1 GHz. It was impossible to get their core to above 1050 MHz even with extra voltage.

http://www.guru3d.com/article/msi-radeon-4890-cyclone-soc-review-1ghz/19

Btw they overvolted their card.
When pantherx12 said "advance over clockers" my mind went straight to in general any 7970 hard volt modded and cooled by liquid nitrogen thus why i will not be impressed by anything but a crazy speed and the comment about the boiling gasses.

At the very least someone finally put a real overclock on their "overclock edition" cards.
After all those whooping 10Mhz OC editions. :laugh:

The really high clock speed totally distracted me from that fact, these are some impressive overclocks, has any product ever came with such an increase between reference and card vendor clocks? or does it just seam much higher due to starting near 1ghz?

Either way has any GPU ever came with a 1.3ghz core?

Maybe, maybe not. 6*27 2560x1440 monitors, BF3, everything maxed out and I think we're gonna go over 3GB easily.
