STARsIE INFORMaCIE:

Postupne sa siri internetom viac a viac chyrov o HD 2900 Pro, preto je cas zalozit thread

schema jadra HD 2900 Pro ?



Zdroj

256 Bit zbernica, 2x ROP quad, 4x Sampler jednotka, 160 SPs

- teda pomerne "slabe" specifikacie na performance kartu :roll:

32 * 10 Flops * 1GHz = 320 GFlops/s

8 * 1GHz = 8 GPixels/s

16 * 1GHz = 16 GPixels/s

a to musi mat jadro prac. frekvenciu 1GHz, co je viac ako optimisticke ...

v porovnani G92 so specifikaciami, ktore sa zdaju byt realne:

96 * 3 Flops * 1.5GHz = 432 Gflops/s

16 * 675MHz = 10.8 GPixels

24 * 675MHz = 16.2 GPixels/s, teda 32.4 GPixels/s (bi-AF)

je to urcite malo, keD priratame este prepady s vykonom pri AA, pokial sa bude vyuzivat shader resolve
----------------------------------

Radeon HD 2900 Pro ma byt zalozena na jadre R600 s vypnutymi jednotkami @ 80nm

RV670, Radeon HD 2900 Pro update (they're not the same)

AMD HD 2900 Pro with 256 bits memory width to arrive in Q4 2007

Better than 8600GTS: Radeon HD 2900Pro comes at the end of 2007

[MichiGen]

S takymito specifikaciami karta prinesie vykon lahko vyssi nez X1950Pro :roll: som zvedavy na tu cenu.Vyzera ze to zatial bude nieco ako 7600GT vs 8600GT

[fobos]

Je to defacto HD2900XT/2 vratane pamatoveho subsystemu. Toto pre G92 konkurencia asi nebude. Bude sa to radit niekde pred 8600GTS a pod 8800GTS 320. Ak sa tieto technicke specifikacie potvrdia, tak ATi stale nebude mat slusnu mainstreamovu kartu ..

Co zatial nema ani nVidia.. ale ATI ma narozdiel od nV dobre miesto na trhu s X1950Pro/GT

[fobos]

Ano, RV570 je stale vyhodne riesenie, ale nebude tu donekonecna . Ziaden refresh architektury R600 sa uz nechysta (az na RV670), ATi teda nebude mat do prichodu R700 kartu, ktora zasdne po boku high-endu v podobe 8800GTX a maistreamu GeForce "G92" . A ako je zname navecsi tok penazi ide prave zo strednej (teda 2900Pro) a low-end triedy

samozrejme, ze sa chysta
to nemusim byt ani jasnovidec ...

A ako je zname navecsi tok penazi ide prave zo strednej (teda 2900Pro) a low-end triedy

najvacsi tok penazi ide z high endu, lenze nieco musi vykompenzovat aj vydavky za vyvoj, cip atD

[fobos]

To je blbost

A mainstream je to, co nejvice vydìlava a to co musi vydìlat aby bylo na High end: TOP karty se podily na celkovem zisku nìjakymi 10%

Vravel som tok penazi nie cisty zisk, to ze nieco musi vykompenzovat naklady na vyvoj tej ktorej architektury je snad jasne a te je prave mainstream a low-end

[crux2005]

nie je blbost

zalezi to od toho ako definujes "najvacsi tok penazi"

AMD/ATi zverejnila informacie o Radeon HD 2900 Pro ?!

este spotreba:



R600 @ 256Bit zbernica, 600MHz takt jadra, 800MHz pamat, spotreba <150W
za 200 USD

[fobos]

Hm, vizera to ze jedina zmena bude v pamatovom radici a taktoch, lebo tam vidim 320 SPs...

Co je vsak stale problem, je desiva spotreba jadra R600 :bored:

AMD preps Radeon HD 2900 Pro and GT for fall

The 'see no deadline' conglomerate company (AMD) seems to prepare not one but two new cards powered by more or less modified R600 cores, one being the already old Radon HD 2900 Pro and one the 2900 GT.

The first, and more powerful card, the Radeon HD 2900 Pro is said to have 320 SPs (or should we say shader units?) working at a yet to be determined clock and it will be brought in September to take some fame and fortune from Nvidia's GeForce 8800 GTS 320MB. The 2900 Pro will have 512 MB of GDDR3 memory and will draw a pretty hefty 150W. Performance should be just under the 320 MB 8800 GTS, but the card will also have a lower price tag.

The second card should be the sweetest offer of the 2000 series as the GT will have 240 SPs (still no clocks) and 256 MB of memory. Although its power draw is also supposed to be close to the 150W mark, the upcoming GT will still be very appealing due to its price that should not go over $220. Production of the Radeon HD 2900 GT is set to start in September with mass availability planned for October. And all this, only if AMD won't miss any new deadlines.

[MichiGen]

256MB? To sa mi nezda dnes moc rozumne, a potom ze ATI "narozdiel od nVidie mysli do buducna" ked na DX10 performance cip da dnes 256MB

[crux2005]

HD 2900GT ma mat len 256MB Vram

urcite, je to menej, ale niekde sa muselo setrit ...

[MichiGen]

To sa muselo, ale nebolo by lepsie namiesto takto zraveho a zrejme nie moc vykonneho riesenia zo zmetkovych R600 cipov spravit nejaky normalny a poriadny mainstream? :roll:

[crux2005]

nuz take je rozhodnutie AMD/ATi

a HD 2900Pro moze byt zaujimava performance karta
