nVidia GeForce 8800GTX/GTS

- drajver tam mam 94.daco (cerstvo stiahnute z nvidia.com pre 8800seriu)
- skusal som to na tom starom Athlone 3200+ (tam co bol slabsi vykon aj na 7950GX2)
- 3DMark06 som nestihol urobit, prave si ponu prisiel zakaznik (som ju mal len 2 hodiny)
- ale ak by som mal supjektivne porovnat tie 2 karty tak na tom slabom CPU v NFS Carbon slapale lepsie ta GX2.... (ale naozaj len subjektivne porovnanie)

T. 8)

najnovsie pre G80 su 97.44

- jo pardon, mal som 97.44 (to 44 ma poplietlo)
- predpokladam ze na silnejsom svabe by to slo podstatne lepsie.
- celkom ma potesil ten chladic, tvaril sa velmi solidne a hlavne bol tichy!!!!

Nove ROPs:

V GeForce 8800GTX je sest ROP blokov, pat v GeForce 8800GTS. (odpovedajuce poctu jednotlivych 64 Bit pamatovych pripojeni) Na jeden blok pripadaju len styri Alphablending jednotky, ale az 32 Z-test units. Pokial je v hre aj farba daju sa vyuzit este 16 Z-test units.(tato "optimalizacia" so zdvojnasobenim Z/Stencil testrate pre bezfarebny Stencil a Z-rendering existuje uz od NV30)

G80 ROP su podla toho optimalizovane pre 4x Multisampling.Na prvy pohlad nerozumne vysoky pocet 192 Z-testov za takt – pokial nie je v hre ziadna farba – prinesie svoje vyuzite pri prednostnom Z-pass. Doteraz trval prednostny Z-pass v porovnani s renderingom este tak dlho, ze v konecnom farebnom renderingu usetrena fillrate ho nemohla kompenzovat – predovsetkym preto, ze Vertexshader musel byt pouzity dvakrat.

Vysvetlenie CSAA od nVidie

pokial mate problem s rozmazanym obrazom na 8800GTS pri napojeni cez DVI priamo...
tu je riesenie...

nvidia control panel, display, manage custom timings, create, advanced, Timing standard, CVT reduced blank, test, exit.

nvidia control panel, display, spravovat vlastne casovanie, vytvorit,
pokrocile, CVT znizene vymazavanie, test, exit...

tyka sa 97.72

niektore starsie idu normalne...
povodne som xcel reklamovat kartu, potom lcd...

Co myslite? Zvladne EN Eliberty 500W zostavu: 8800GTX, FX-57,2disky,jednu dvd mechaniku, ?

barco

Ano

Zober napr. ze tato zostava
Intel Core 2 X6800 - 2.83GHz, 2x 1GB RAM DDR2-800, 1x 8800GTX, 4x SATA HDD, 1x ATA HDD, 1x DVD-ROM, 1x PCI karta.
si zoberie v zatazi 393W...

m4x

kolko zere vlastne taka karticka v kompletnej beznejsej zostave bez zatazi ? (pytam sa na zaklade zaujmu predstavy spotreby pri beznom pouzivani pri prezerani filmov, stahovani a pod., predsa len v noci tahat 12 hodin s urcitou spotrebou a to pravidelne nemusi byt sranda, tak ma to zaujalo)

~ 215W

Rys napísal:Rather than wonder about a discrete CB cache, I changed it to read that there definitely is one since we've since confirmed that's the case.
Confirmation that scheduler clock runs at half the shader clock (675MHz for 8800 GTX f.e.).
Confirmation that the missing MUL is serial to interp/SF and not available for general shading just now.
Confirmation that SPs are arranged '8x2' in a G80 shader cluster.
Confirmation that each cluster has its own dedicated register space rather than wondering.
Those are the big changes in presented info, the rest was mostly just correcting layout issues, grammar and spelling, etc.

Muzes mi prelozit co se tam pise?Co sem prelouskal tak neco o 2MUL jednotce..

kazdy mesiac novy ovladac od nVidie - podobne ako ATi
Prvy zo serie ma prist uz vo february a ma nahradit FW 100.59 s Beta statusom - nahrada ma mat uz WHQL certifikat

NVIDIA told me that they planning to start releasing a new version of their Forceware driver for Vista at least once every month. I say at least because Diercks said that if they find several game fixes or bugs that are substantial they may have intermittent releases as well to help appease the gaming masses. This move is very similar to the driver development cycle that ATI’s Catalyst drivers have been in for a couple of years now, with updates about once a month. Having this type of regular schedule should help NVIDIA users feel more at ease about their purchases knowing that a fixed time length is ahead of them to await another software release that could address whatever issue that ails them.

potvrdene, ze schelduler bezi na polovicnej frekvencii shader coru - (675MHz u GeForce 8800GTX)
potvrdene, ze sa chybajuca MUL nemoze zatial vyuzit na shading
potvrdene, ze "SP" su zoskupene po 2x8 v G80 shader clustery
potvrdene, ze kazdy cluster ma vlastny register ktory je vacsi ako sa predpoklada
