nVidia G9x - informacie (povodne aj spekulacie)

[fobos]

zeby nVidia 8800GT vykonom nebola to prave co nVidia ocakavala ?

- nVidia vydava 8800GTS s 112SPs z neznameho dovodu, keDze 8800GT je tu zachvilu link
- takty 8800GT nie su prave najvyssie, kartu trapia vyssie teploty link
- dokonca to vyzera, ze 8800GT nema podporu SM4.1 link
- zda sa , ze nVidiu trocha zaskocil skory prichod a vykon HD2950Pro tak vydava 8800GTS s 112SPs + 28ROPs
- su to samozrejme len spekulacie, no vyzera to zaujimavo, hlavne ta 8800GTS ...

[Tomax]

- a tych 16 SPs tam urobi aj nejaky vykonovy skok? nechapem
- 8800GT bude teda slabsia ako 8800GTS nie?

- a tych 16 SPs tam urobi aj nejaky vykonovy skok? nechapem

tazko povedat, ako som pisal , uvedenie tejto verzie je zaujimavy krok od nVidie, ale budiz

- 8800GT bude teda slabsia ako 8800GTS nie?

Vykon by mal byt praveze dost podobny, ale na HD2950Pro stacit zrejme nebude (ver. Gladiator, len tak na okraj ta ma az neuveritelne takty 825/2400MHz !), teda ak ATi robila aj nejake zmeny v navrhu jadra, lebo vykon zas bude podobny sinusoide ako u HD2900 podla danej hry

[crux2005]

nie su to "len" ALUs a ROPs ale aj TMUs - nakolko sa prida jeden cely cluter - teda nova GeForce 8800GTS ich bude mat 7. (stara ich ma 6) -> + 15% (a viac) vykonu

-------------------------------

trochu zhrniem moje domnienky, napady atD:

- GeForce 8800GT je vykonom niekde tam kde je teraz GeForce 8800GTS s 96 SPs -> teda karta s "nizsim" oznacenim by bola ~ vykonna ako druha karta s vyssim oznacenim. (Tato vykonnostna uroven bola jasna uz urcitu dobu) Preto sa zvysil vykon GTS.

- GeForce 8800GT by mala byt takisto podobne vykonna ako "slabsia" verzia RV670 Revival.

- voci silnejsej verzii Gladiator sa postavi asi zatial "nova" GeForce 8800GTS so 112 SPs, pokial nepride nahrada, ktora sa bude dat vyrobit lacnejsie - rozne naznaky tu uz mame. Mozny je dokonca aj ultra high end verzia karty. K tomu ale neskor.

zeby nVidia 8800GT vykonom nebola to prave co nVidia ocakavala ?

pochybujem

- nVidia vydava 8800GTS s 112SPs z neznameho dovodu, keDze 8800GT je tu zachvilu link

ano, Link

- takty 8800GT nie su prave najvyssie, kartu trapia vyssie teploty link

nie su najvyssie - ale to ani nie je potrebne - nakolko ma karta dostatok texelfillrate a z/stencil vykon atD v porovnani s predpokladanymi specifikaciami RV670
nedostatocny ale moze byt aritmeticky vykon, ale takt SC zatial nepozname.

teplotne problemy by finalna karta nemala mat:



nova verzia GeForce 8800 GT s mierne vacsim chladicom

- prave s "teplotnymi problemami" vznikli zaujimave spekulacie. Vcera informoval The Inquerer v clanku:
G92 has heat problems
Panicked, last minute 'Thermal Analysis' suggests, ze high end cip G92 ma teplotne problemy (podobnu spravu vydal potom aj Vr-Zone) - die size ma byt ale az 289 mm^2 - co je velmi vela pre "performance" G92. KeD to spojime s obrazkom DIE G92, ktory ma HS atD tak nam moze vyplynut, ze nVidia chysta este 65nm shrink G80 + nejake vypoctove jednotky atD a teplotne problemy ma tato karta a nie G92. Vacsi chladic bol planovany uz od zaciatku - nakolko sa prve verzie kariet, ktore sa dostanu k AIBs nemusia zhodovat s finalnymi a taketo upravy su pomerne bezne.

- dokonca to vyzera, ze 8800GT nema podporu SM4.1 link

nuz nieco take som uz davnejsie napisal aj ja ...
medzicasom sa ale objavila fólia - Link, ktora pise o tom, ze uz aj GeForce G8x hardware plne podporuje D3D 10.1 ...

More 8800 GT Card Pics Surfaced; Black PCB

It seems like more GeForce 8800 GT card photos have surfaced online as seen in our forums and apparently another website in China got the inside scoop. This time round the PCB is black in color, which looks better than the reference green PCB. The GPU heat-spreader looks the any other G80 series and the rumored die size of G92 is 289mm2 as opposed to ~480mm2 of the G80.

[socket]

gpu vyzera presne ako G80, dokonca ma aj taku velkost s porovnanim karty :roll:

[crux2005]

to je len HS, velkost jadra podla toho tazko urcis ...

GeForce 8800 GT Cooler Has 3 Heat-Pipes

CHW has a slide on the the GeForce 8800 GT which confirmed the specs we told you earlier. Also we heard that the single slot cooler on the 8800 GT card has 3 heat-pipes and Nvidia told its partners that it won't be hot.

Updated Specs of GF8800GT based on NVIDIA G92

The 8800GT graphics card is PCIe 2.0 compliant and come with a core clk of 600MHz and memory will be at 1800MHz. Shader clk is expected to be running at 1.2GHZ (to be finalised).

:hmm:

4 C @ 600/1200/900MHz a TDP: 110W -> v 65nm, tu nieco nesedi ...

mne osobne by sedelo, keby 8800GT bol die shrink na 65nm -> teda 6 C @ 600/1200/900MHz alebo 4C, ale nie G8x clustre ...

And ofcourse you always play the popular game 3DM06. The HD2900XT was also a good performer in 3DM06, but I don't need to remind you how it did in most games compared to the GF8800GTX (especially with AA).

Hm, zeby sa nVidia za rok od uvedenia G80 zmohla len na Die-Shrink jadra G80 ...

Ak su Crux tie tvoje info pravdive tak nam nVidia akosi zaspala :roll: . Mno, Shader Core malo podla prvotnych info bezat dokonca az na 1800Mhz ....

AMD sa pri tomto "pokulhavani" nVidie moze len radovat

[dexterav]

zatial vyzera 8800GT ako orezana 88GTS :roll:
alebo 2x86GTS (nemyslym tym sli alebo dual)

GeForce 8800 GT Has 112 SPs Clocked @ 1.5GHz

Several sources are suggesting that the upcoming GeForce 8800 GT has 112 stream processors like the new GeForce 8800 GTS 640MB SKU. We also heard that its shader clock is running at 1.5GHz. CJ did some nice analysis on the Nvidia's strategy here on why is there a new 8800 GTS SKU. He revealed that there is a shortage of GTX cores but plenty of GTS cores going around that didn't quite make it as a GTX

Aky zmysel ma potom uvedenie 8800GTS 112SPs

[crux2005]

Ak su Crux tie tvoje info pravdive tak nam nVidia akosi zaspala :roll: .

nuz, tie informacie co su tu postnute nie su odomna - ja len zozbieram tie, ktore su na internete a potom postnem - nove informacie, ktore este nie su verejne dostupne, nezverejnujem.

AMD sa pri tomto "pokulhavani" nVidie moze len radovat

to este len uvidime
nVidia uz dlhsie zhmlieva pravdive informacie a dava do obehu nepravdive.
-------------------------

ok, povedzme, ze G92 ma naozaj len 4 clustre, nie G8x, ale nejake nove - teda G9x clustre.

hmmm, to by znamenalo, ze jeden cluter - pokial ma mat GeForce 8800GT dokopy 112 ALUs, obsahuje 28 ALUs. Voci 16 ALUs je to dost velke zvysenie, ktore by sa dost negativne prejavilo, v latencii, granularite atD - teda tieto spekulacie sa mi nezdaju byt pravdive.

Hm, zeby sa nVidia za rok od uvedenia G80 zmohla len na Die-Shrink jadra G80 ...

pokial by to stacilo, preco nie ? AMD/ATi nevyvija taky tlak, ze by bolo potrebne zvysovat "vykonnostnu latku". Avsak G92 v performance verzii urcite nebude G80 @ GTX len v 65nm - taky cip by nVidia nepredavala za $250.

btw:

mozno sa niekto "hral" a spravil na fotke z "novej" GeForce 8800GTS - GeForce 8800GT, alebo "nova" 8800GTS je 8800GT

NV 8800GT scores 11760 in 3Dmark06

We have got the initial scores of GeForce 8800GT runnning on a ASUS P5K-D board with Core 2 Quad Q6600 processor. It scored 11760 in 3dmark06. The Core runs at 600MHz while memory is at 1800MHz.

tak to 3Dmakr06 scóre stale rastie

UMC receives Nvidia G92 orders

G92 sa bude vyrabat u UMC, nakolko nema TSMC dostatocne kapacity pre nV - co by mohol byt dovod "nizkych" taktov



G80 ma 42.5 mm ^ 2

96 Stream processors G92 rumoured after 29 OCT

On 29 OCT, NVIDIA will launch the 8800GT (G92). The model scheduled is a 512M card with 256bits memory interface, it has 112 stream processors.

What we heard is that there seems to be plans to launch another lower end model of G92. It will come with 96 shader processors and 256M / 512M GDDR3. This model may or may not launch. It all depends on sales of the first 8800GT and AMD's RV670.

Geforce 8800GT dissipates 110W

G92/D8P dissipates about 110W and this is what Nvidia is telling to its loyal and less loyal chaps.

In order to cool such a card you only need a single slot solution and it doesn’t look that this Nvidia’s 9 inch board will be a noisy one. The card has 512MB or 256MB of frame buffer and by default it will come as the DDR3 version and you won’t need more than a single 2x3 connector to make it work.

It is better than HD 2950XT, as this card dissipates some 135W, but the slower PRO version dissipates 105 only.

8800GT comes with HDMI dongle

Nvidia realized Multimedia

Nvidia D8P/G92 or simply called Geforce 8800GT will come with HDMI dongle and Nvidia is following ATI RV630 / RV615 footsteps here.

It was upsetting how this little thing boosted ATI’s sales as many people have HDMI LCD and Plasma screens and they certainly want to connect their PCs on these big screens.

The great thing about HDMI is that it works really easy and it even comes on notebooks and this is really the first plug and play display technology. The big problem of HDMI is the royalty you need to pay and the HDCP license but if you want to enjoy HD-DVD or Blu-Ray you have to live with this evil protection thing.

D8M / G98 is a $17 chip, entry level

Replaces 8400GS, G86

Nvidia’s G98 is also known as D8M and it's a $17 chip that is set to replace the current G86, 80 nanometre chip.

Nvidia’s new D8M, G98 is a $17 chip that will replace 8400GS cards in the OEM and channel market, but it will be a tough fight as Nvidia has very cheap Radeon HD2400 card to fight in this segment.

The card will cost just above $50 and it will be ready by middle of November. Traditionally Nvidia was losing to ATI in this market segment and ATI is very close with its 55 nanometre chips as well.
