Sapphire Readies Radeon HD 7970 Cards with 1335 MHz Core Clock, 6 GB Memory

btarunr · Dec 31, 2011, 09:37 AM

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.

The other card that caught our eyes is codenamed "FLEX 6G". The Flex variant typically features a flexible display output configuration. This card is said to have six mini-DP connectors. While this card sticks to AMD reference clock speeds, it packs a whopping 6144 MB of video memory, all wired to a single GPU. While 4 Gbit GDDR5 chips don't exist, we expect Sapphire to be using 24 * 2 Gbit chips on this card, with twelve sets of two chips sharing 32 bit paths. Then there are other milder factory overclocked cards apart from the Atomic; there's Toxic 3G, and VaporX 3G, both packing impressive out of the box clock speeds.

Two of these in crossfire... Over kill for my needs? Yes, but very much do want.

pantherx12 · Dec 31, 2011, 09:41 AM

That's a phenomenal over clock for a retail card!

uuuaaaaaa · Dec 31, 2011, 09:42 AM

im wondering how these will perform

Pandora's Box · Dec 31, 2011, 09:45 AM

6GB of memory on one card, wow...

pantherx12 · Dec 31, 2011, 09:46 AM

I wonder how far these things can be pushed by advance over clockers ....

bear jesus · Dec 31, 2011, 09:46 AM

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 expect to see 2 GHz+ otherwise i shall be unimpressed by them and their boiling gasses

Dj-ElectriC · Dec 31, 2011, 09:48 AM

1335Mhz core clock?
how... what? wh... wh... how?! jesus fu**ing christ, seriously?

pantherx12 · Dec 31, 2011, 09:49 AM

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

the54thvoid · Dec 31, 2011, 09:52 AM

Hmm, water cooled they say.... Tell me more....

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

The air cooled one does 1335 mhz as well apparently

LAN_deRf_HA · Dec 31, 2011, 09:56 AM

That would blow past just pretty much everything by a good margin.

Zubasa · Dec 31, 2011, 10:32 AM

2Mhz more on the core and it will make a leet card.

You know someone will do it.

7970 l33t edition! for all your H4X0R needs!

crazyeyesreaper · Dec 31, 2011, 10:34 AM

i was about to say 2mhz as well for 1337 awesome but ill just do it myself haha

crazyeyesreaper · Dec 31, 2011, 10:50 AM

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

blanarahul · Dec 31, 2011, 11:24 AM

This is what the 7970 was supposed to be

wolf · Dec 31, 2011, 11:28 AM

holy schmidt 1335mhz is a whopping core clock and I like their particular choice too

this is going to be, one hell of a card. I'll have two please tooth fairy.

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.

Zubasa · Dec 31, 2011, 11:41 AM

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

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?

Sorry mate! Didn't see that!

6GB...may take years for a game to finally be able to fill all that.

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