KingP1n napísal:Uz som o tom niekde aj cital, a teraz sa to prejavilo v praxi - HD2900XT je optimalizovana pre D3D10 a v DX9 nieje az tak dobra.
Kazdopadne pokial bude cena na urovni 8800GTS tak je to lepsia kupa.
jj...ale predpokladam ze NV znizi cenu GTS640 aj GTS320 a to by zase trochu zmenilo situaciu
hlavne GTS320 by mohla mat zaujimavu cenu potom...
inak stale je to tak ze niekde drti GTX a niekedy horko tazko staci na GTS640

Ak su tie testy v Oblivione pravdive, tak by ATI mala riadne zamakat a vyriesit problem s poklesom FPS pri zapnutom AA... mozno sa to tyka konkretne len Oblivionu, ale v porovnani s G80 v tomto teste R600 prepada na plnej ciare...
Inak podla cerstvych neoficialnych testov je HD 2900 XT v high-ende IMHO s best pomerom cena/vykon...
A napadla ma ma este jedna vec, vykon R600 je vo Viste, resp. v DX10 velmi slusny (aj ked mozno v testoch, ktore o vykone moc nepovedia)... ze by sa ATI viac orientovala na optimalizaciu ovladacov pre DX10...? Mohol by to byt celkom dobry obchodny tah... chcete NAJ vykon vo Windows Vista...? kupujte novu ATI...!
AndyTX napísal:[...] Granted G80 still has a lot of space to improve in that area: a recent test that I did indicated that even having *any* geometry shader present (I used an "identity" geometry shader that just passed through the triangles) cut the performance of the shader in *half*.[...]
Rys napísal:Currently it seems to be that if any GS shader is scheduled, the hardware will decrease the number of threads running for the other types indiscriminately. That's the driver doing that, though (as far as I can tell), rather than something at the hardware level.
G80's GS is worse than it should be (half-performance for a null shader ), theoretically, and you think that NVidia building a unified architecture is somehow surprising to ATI? Apparently the surprise is that it's not working at all well.
nAo napísal:Well, I wouldn't be suprised if drivers can tweak or even modifying load balancing policies, it was possible on more primitive architectures so I don't see why things should change now.
Regarding DX10 performance I'd like to see tested MUCH MORE features than geometry shaders, it's not going to be the end of the world if GS implementation is not uber fast now, there's time for that, as long as devs can start to use it.
Tak medzi X2600XT a X2900XT je brutalny skok v spotrebe, mainstream bude mat zrejme dobry pomer vykon/spotreba.
Inak nieje zatial ziadny slovensky velkosklad kde uz je X2900XT v cennikoch?? Zatial som ziadny nenasiel alza.sk nepocitam

Takze take kratke zhrnutie nemeckeho testiku, ale vacsina z toho uz je davnejsie jasna:
- slusny vykon za vyhodnu cenu (+ bundle hry...), vykonovo je vsak len nieco malo nad 8800GTS, na GTX a Ultra dnes vykonovo zaostava...
- slabsi texturovy vykon v porovnani s 8800, co sa prejavi hlavne pri starsich hrach narocnych na vykreslovanie textur...
- vysoka spotreba, v porovnani s 8800GTS dvojnasobna...
Celkovo ale velmi dobra karticka...
