ATi Radeon HD 2900XT ... #2. diel (premenovany)

[crux2005]

nj, variance shadow mapping

Note that this implementation is relatively unoptimized; it's more of a "proof of concept". In particular, the shadow split locations could be chosen a lot more sensibly, and even some basic frustum culling would greatly improve the performance of rendering the different shadow map splits.

Troska by ma zaujimalo, ako to ma ATI vyriesene ??
Prehlad od Nvidie sme tu uz mali, ale ako urobila ATI ten GPU, nemate niekto nieco ?? Okr toho si myslim ze ATI urcite nebude pozadu bude sa snazit byt stale lepsia, ale ked to chvilku trva. Hold na riadny vykon za menej penazi si musi pockat.

vela by si uz chcel ...

NDA este stale plati

- nVidia sa afaik nepodielala na ziadnom clanku vydanom na www.pretaktovanie.sk

To crux2005
Nemyslim to tak doslovne, na vela serveroch som si cital ako je rieseny cip Nvidie, skoda ze si to nemozem porovnat, dost by ma to zaujimalo.

Este budes musiet vydrzat par dni

Cize pokial by sme zili v idealnom svete a kazdy by pisal na komponenty REALNE udaje (seasonic k niektorym typom udava efektivitu okolo 90% .. kiez by to bola pravda) tak by tu masinu potiahol aj idealny 350W zdroj + 8800Gtx (okolo 200W dufam ze nedristam) = cca 550W (samozrejme pocitame s "trosku" pretaktovanym quad-core ,ktore moze mat o nejakych odhadujem 80W vyssiu spotrebu) .. co z toho vyplyva ?
Quad Core2Duo a 2x8800GTX ? Nehrozi .. odskusaj a posli pohladnicu z nemocnice

[dexterav]

hm...
tak preco netestuju na 400W?
a sli na 500W?
myslim ze 500W + SLI GTX alebo aj CF HD2900XT + nejake OC core2 je o hubu...

[MichiGen]

Chcel som len vyvratit famy o gigantickej zravosti 2x8800GTX

Even with SLI 8800 GTX graphics cards, there is really no need to purchase anything greater than a 600 watt power supply

The GeForce 8800 GTX appears to only suck down around 135 watts of power at full load based upon our testing. Which makes sense given our SLI GeForce 8800 GTX system never demanded more than 530 watts

fanik z PCT fora sam hovori ze u neho X2900XT bezala na 400W zdroji tak uvidime

[dexterav]

no ale tie karty su giganticky zrave...
ved sa da urobit slusne PC ktore bude mat spotrebu priblizne rovnu tej XT alo GTX

jo inak napr. ta moja GTS bezala docasne na 350W zdroji
a ten chill tiez isiel asi den nez to zacalo robit trable...
ja len hovorim ze to netreba podcenovat...


inak aj pri Enermaxe skoci vetva +12V relativne dolu pri fullloade...

[MichiGen]

ja len hovorim ze to netreba podcenovat...

Na tom sa urcite zhodneme i ked sa mi nechce verit zeby GTS neutiahol Chill 500W toby mohla byt skor nejaka zavada v tom zdroji, alebo slabe vetvy? ale myslim ze sme dost OT

[crux2005]

pri pohlade na vykon ROPs G80 pochybujem, ze R600 predbehne v tom deme - "Variance Shadow Maps" GeForce 8800GTX ...

priblizit sa priblizi ... ale nepredbehne
podobne by bolo potom aj vysvetlenie, preco je vykon R600 v 1. teste 3Dmarku06 taky slaby - nakolko pouziva vela shadow maps

Jo, uz davnejsie si v tomto threade pisal, ze vykon ROPs u R600 je nizsi ako u G80 a ze s nimi mala dokonca ATi problemy a tie sa mozu prejavovat aj vo finalnej verzii cipu... sice sa do procesu vykreslovania sceny natolko nerozumiem, ale tento testik by tomu len nasvadcoval...

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.

[crux2005]

to je test GS v D3D 10 ...
-------------------------

tak ci tak, zaujimalo by ma ako merali tie fps, nakolko FRAPS nefunguje pod Windows Vista a aplikacia sama (CubemapGS) nedokaze zobrazovat fps ...
