HD 7970 Overclocked to 1.26 GHz: 28 nm Tech Really Stretches Its Legs

It looks like the new AMD Radeon HD 7970 could be a bit of a dark horse and a lot more potent than its stock specifications would suggest – excellent for creating a competitive graphics card market. The reviews at stock speeds show the flagship HD 7970 to be around 10-15% faster than NVIDIA's flagship GTX 580, which doesn't seem all that impressive since the GTX 580 has been on the market for over a year now. However, what the reviews haven't really shown, is what kind of an overclocking monster the HD 7970 is. It definitely looks like AMD could have easily beaten the GTX 580 by a much bigger margin than they did, had they wanted to and it makes one wonder why they didn't.

VR-Zone have spent the New Year weekend overclocking this beast, having reached a whopping 1.26 GHz core clock speed with their HD 7970 - and decent benchmark improvements to go with it. Also, with the fan at 100%, the card never got above a very comfortable 68 degrees centigrade while running Furmark, which is amazing considering how this test is specifically designed to heat a graphics card to the max - but please see the update at the bottom of the article. The stock cooler may be noisy, but it's certainly very effective: an excellent result which will prolong the working life of the card.

100% fan speed? ne hvala

 

[Lukija]

100% fan i max 68*C je super. Odreci se % u korist temperature + neko custom hladjenje kao TwinFrozr ili slicno = win. Ja na GTX570 samo mogu da strepim da ne pufne VRM ako Furmark i OCCT rade punom parom. A nisam ni blizu ni taktu ni performansama.

ma briga me za temp, 100% je usisivac. To je samo za neki bench ili tako nesto. Nije za visesatno igranje, osim ako nisi mazohista (ili sadista ukoliko ne zivis sam).

edit: nema uopste veze sa ovom kartom, vec uopste.

...to je uobicajena procedura kod testa za OC da se vent stavlja na 100%. Secam se da su tako testirali i OC za gtx480 kad je izasao, sa ventom na 100% samo sto je temp. isla preko 100C za nekoliko minuta.

ne vidi se slika koju si okacio.

^jel u tom tekstu pise da ce i kapler biti predstavljen krajem januara ili pocetkom februara, ili sam ja nesto krivo preveo?

Ne racuna se, i ovo je na 100% fan

Lepi taktovi, ostaje da vidimo softverski deo i skaliranje u igrama, pa i u sintetici.

 

[gx-x]

ajd sad ozbiljno, koji je max OC te karte (u proseku) za 24/7 a da pri tom ostane tiha? Recimo, 5850 je bila tiha i ispod 80C sa fan speed do nekih 65%, na 100% je bila na 65C ali je buka nesnosna. Na 65% fan speed max OC je bio oko 945mhz, na 100% ~980mhz.

Meni je za referentni 5850 slusni limit bio do nekih 38/40% , pa sam joj ubrzo stavio accelero ... a da 7970 ostane tih i oc, pa tesko uz ovako dobar overkloking ...

Yup .

P.S. memorija na 1900 ...

Kakvo skaliranje u konzoloskim portovima mozes da ocekujes ?

 

[monteboy]

impresivne su temperature chipa pa i pri overclocku. 1700MHz pod ln2 na referentnom dizajnu je takodje fin podatak nego da sacekamo bolje layout varijante ima ovdje jos prostora ....

Ne vidim gde je neko spominjao konzolaske portove...

Upali Gothic 4, opanji sve na max, pa vidi rezove i prosecan FPS, a igra izasla pre mnogooo meseci...

Konzolaski portovi ce da rade i na slabijim kartama

 

[hsv.stoned]

Izgleda malo ljudi zna da je najzahtevnija igra danas- Serious Sam 3
Na 1680x1050 kada bas sve odvrnem na max i 4x Super Sampling AA imam 6-7 fps prosek a igra je dx9 A sa samo 2 podesavanja na off [ssaa naravno] i jos 2 na low imam 50 fps prosek.
Neoptimizacija ili manje potrebne graficke opcije, svejedno. Inace je Croteam uvek ostavljao najdetaljnija podesavanja grafike. E sad zamislite kada bi Battlefield 3 ili Crysis 2 imali ovako detaljna dx11 podesavanja, 4 7970 ne bi pokrenule igru sa 30 fps

Bas bih voleo da vidim rezultate jedne 7970 u tom dx9 Serious Sam 3, tipujem na max 35 fps u 1080p kada se sve to odvrne

HD 7950 se izgleda odlaze do februara

Last week we posted an in-depth review of the Radeon HD 7970, the first in a series of upcoming graphics cards from AMD to utilize a 28nm fabrication process. Although we concluded that the card is extremely fast, it won’t be available to gamers worldwide until January 9.

This paper launch is uncharacteristic of AMD and led many media outlets to question the move. As a result, AMD has reportedly decided to delay the launch of the Radeon HD 7950 until early February. According to Guru of 3D, AMD made the decision to avoid similar concerns and have the card available on the market when it actually launches.

The Radeon HD 7950 is based on the same Tahiti core used in the higher-end 7970 except that four of the card's GCN (Graphics Core Next) compute units have been disabled. This will result in what AMD calls the Tahiti Pro core, where as the GPU on the 7970 is known as the Tahiti XT. According to NeoSeeker, the 7950 will feature 1792 Streaming processors and a 3GB GDDR5 frame buffer running on a 384-bit interface. The card will use the same video output configuration as the 7970, meaning it can support up to six screens.

The only unknowns at this point are the total TDP, clock speeds and price point that the 7950 will launch at. It looks like we might have to wait at least another month to get these answers unless AMD has something to share with us at CES 2012.

pa gotik 4 je upravo konzolaski port I igra je krshina nakon druge mape...

 

[Uruk]

Ta arkadija se meni smucila odma posle demoa, ali je fino reagovala na OC... Ja sam probijanjem ccc limita i klokom za jos ~150MHz dobijao 5+FPS, u demou.... Mislim da se na to mislilo kada je rec o skaliranju.

 

[gx-x]

pa svaka reaguje na oc osim ako nije zakljucana na 30fps, a vec daje 30fps zar ne? PS. Demo gotik 4 je bio optimizovaniji u odnosu na finalni proizovd kome je trebalo 3 patcha da proradi, a dotle me je igra vec opasno smorila...Kad krene kisa i wet surfaces, vidi se limit engine-a ako je rezolucija preko 720p, u tome je problem.

 

[Uruk]

...trebalo bi ako je dobro optimizovana.
U toj igri, tj. demou sam primetio jer je bila zahtevnija od ostalih, malo mi je seckala ispod 40FPS na nekim za oko prihvatljivim podesavanjima, pa sam klokovao iz rive preko ccc limita i dobio igrivih 45+FPS.
