Multiple Radeon HD 7950 Cards Listed in Europe

Quote:

Not to be outdone by their US-based brethren, several European stores have jumped the gun and put up for pre-order the (still not officially announced) Radeon HD 7950 aka AMD's second 28 nm-powered graphics card. The listings in Europe reveal three HD 7950s, two that seem to be based on AMD's reference design (one from XFX, one only carrying the AMD brand) and a custom model coming from Gigabyte.

All three cards feature DirectX 11.1 and OpenGL 4.2 support, 1792 Stream Processors, a 384-bit memory interface, 3 GB of GDDR5 VRAM clocked at 5000 MHz, CrossFireX support, and include four display outputs - DVI x 1, HDMI x 1, mini DisplayPort x 2. The 'stock' models have a GPU clock of 800 MHz while Gigabyte's card (GV-R795W3-3GD) is listed with a core clock of 900 MHz (although it may be a typo). The GV-R795W3-3GD also has a blue PCB and a dual-slot, triple-fan (WindForce style) cooler.

The Gigabyte Radeon HD 7950 is priced at 2053 PLN (Polish Zloty) which equals to about 635.6 USD / 483.6 Euro, XFX's model costs 419 Euro, while the AMD-branded card is £435 (519 Euro).

Report: NVIDIA shipping Kepler to notebook OEMs

Kepler is likely to power select performance and high-end GeForce 600M series products. AMD's GCN based HD 7000M GPUs are also due in notebooks around the same time. One such April-bound range is Dell's Alienware line-up, which is based on the Chief River platform powered by Ivy Bridge CPUs, with GPU options such as Radeon HD 7970M (GCN) and GeForce GTX 660M (Kepler).

Singurul lucru care poate sa-i distruga pe AMD e ca acel 660 chiar sa fie aproape/la fel de performant ca 7970 pentru ca astfel, placile GK100 nu o sa aibe rival, de aia cred ca strategia de a anunta 660 ca prima intrare din serie + zvonurile ca va fi peste 580 ( indirect >/= cu ce a lansat AMD ) e foarte buna, dar foarte posibil sa nu fie deloc aproape de adevar, chiar si asa, cam riscant sa dai 2500 -> 2200 cand lucrurile is neclare.

Small Review for Radeon HD 7950 Surfaced - Expreview

Probleme cu procesul de 28 nm

AMD a lansat deja GPU-uri realizate in procesul tehnologic de 28 nm. Insa Tahiti, primul lor reprezentant, este in cantitati extrem de limitate, si nu a putut fi introdus pana in acest moment decat sub forma performanta Radeon HD 7970. Si asta pentru ca trecerea la noul proces tehnologic se dovedeste problematica.

Si nu pentru ca ar fi erori de proiectare sau de design. Ci pentru ca trecerea se face prea repede, iar producatorii de chip-uri nu au timp sa testeze si sa verifice suficient noul proces. TSMC are pe lista de asteptare zece arhitecturi diferite la 28 mn (GCN de la AMD inclusa), de la sapte companii. Deci are ceva treaba in viitorul apropiat.

Nici GlobalFoundries nu are o viata mai usoara, atat la 28 nm cat si la 32 nm. Insa aici problemele survin din alte motive, timpul alocat fiind ceva mai lung. In primul rand ei folosesc doua design-uri diferite, unul de la AMD si altul de la IBM, deci au de doua ori mai multe batai de cap. In al doilea rand, fabricile din Germania si cele din SUA nu comunica, din cauza unei neintelegeri de conducere. Deci de multe ori aceeasi problema trebuie rezolvata de mai multe ori.

Pana la urma insa randamentul la 28 nm si 32 nm se va imbunatati, si costurile de productie vor scadea. TSMC se asteapta ca in 2012 chip-urile pe 28 nm sa reprezinte 10% din total.

Totusi, pentru cei care nu au sau nu vor sa dea 2400RON pe un Radeon HD 7970 AMD le ofera incepand de azi varianta mai accesibila denumita HD 7950.

Un numar de 1792 unitati de stream (fata de 2048 in cazul HD 7970) si frecvente micsorate pana la 800 MHz pentru GPU si 1250MHz ar trebui sa faca din Radeon HD 7950 o placa semnificativ mai slaba decat HD 7970 dar totusi suficient de puternica sa depaseasca batranul Geforce GTX 580. AMD are astfel posibilitatea sa scape si de GPU-urile Tahiti ce au unitati de procesare defecte sau nu pot functiona la frecvente ridicate.

Desi s-a vorbit mult de o presupusa deblocare trebuie sa va spun ca acest lucru nu este posibil, AMD dezactivand fizic unitatile defecte. Cayman era un GPU mult mai putin complex decat Tahiti, acesta fiind si motivul pentru care AMD a lasat posibilitatea de deblocare in cazul seriei HD 6900 (procentul placilor HD 6950 ce nu puteau functiona la specificatii de HD 6970 fiind redus).

In afara celor testate mai sus (Sapphire HD 7950 Dual Fan OC Edition, PowerColor HD 7950 PCS+, XFX HD 7950 Black Edition) alte variante custom au fost lansate de MSI si Asus:

ASUS Launches Trio of Radeon HD 7950 Graphics Cards

ASUS kicked off its Radeon HD 7950 graphics card lineup with three models, the HD7950-3GD5 which sticks to the cost-effective AMD reference design; the HD7950-DC2-3GD5, which is a DirectCu II model that sticks to AMD reference clock-speeds; and the HD7950-DC2T-3GD5, which is a DirectCu II TOP model, which features factory-overclocked speeds of 900 MHz core with 1250 MHz memory, while the other two models feature 800 MHz core with 1250 MHz memory.

The HD7950-3GD5, which likely sells for US $449, is based on AMD's cost-effective central-fan reference design. The HD7950-DC2-3GD5 uses the company's triple-slot DirectCu II cooler, which is also featured on the Radeon HD 7970 DirectCu II, and is known to provide excellent cooling with low noise, though at the expense of its size. This card will likely be $15-20 costlier. Lastly there's the HD7950-DC2T-3GD5, which likely charges a further $20 premium for its factory overclocked speeds, taking its price close to $490.

Din cate am vazut exceleaza doar in Battlefield 3 mult peste 580gtx.In rest cu 5-10% mai buna ca 580GTX. Ce mi-a placut este ca ajunge cu OC un 7970.Cam scumpa, daca mai taiau din memoria vram era pe la un 17mil, dar asta dupa ce apare o versiune cu 1.5vram, aia cred ca v-a fi best buy.Prea putine ROP's, inca driverele nu sunt mature sa isi arate adevarata fata seria 7 AMD.Sta bine la consum in LOAD.

Retro Vizion · 31.01.2012, 13:10

Niciodata n-au facut driver-ele minuni (cel putin, nu pentru AMD). Cum spuneai si tu, cam scumpa. Pe varianta disponibila la garaj n-as da in veci 2000 de lei...

...pe de alta parte, face 7970-ul sa para o investitie proasta. Clock/Clock nu pare a fi mai mare de 3-5% diferenta. Partea proasta-i ca nu e cu mult mai ieftin ca 7970-ul si calitatea "siliciului" nu se compara cu cea a fratelui mai mare. Astept varianta cu 1.5 GB....

CalinTM · 31.01.2012, 14:00

Pai daca au pastrat la 7950 acelasi numar de ROP's acelasi numar de VRAM, aceeasi magistrala, au scazut doar unitatile de procesare cu 256 daca nu ma insel, nu ma mira pretul mare.Si daca nu ma insel a doua oara ambele placi au acelasi controller care poate controla maxim 8 faze.

Dupa ce au testat 57 sample-uri, astia de la PassMark au plasat 7970 pe locul 2, dupa 580 (cam la egalitate, de fapt). vezi aici
Totusi, cam ciudata aplasarea 6990 (locul 7) si 6970 (locul 8).
