Re: G80 - G90 a dalsi novinky
první slajd:
- odkdy se v oficiálních materiálech píše něco o OC?
- proč je schéma čipu stejné jako u G80 a s ještě zdeformovaným poměrem stran?
- proč schéma čipu přesahuje rámeček dole a ty "bloky" vpravo do něj přesahují rámeček nahoře?
- odkdy se leaklé slajdy objevují prvně na východních webech?
druhý slajd: kdyby byla podpora DX10.1 závislá na výpočetních jednotkách, tak proč ne, ale největší změny DX10 vs. DX10.1 se právě vůbec netýkají shaderů - je vyžadována podpora pro per process virtual memmory + full fledged page faulting with immediate context switching, což jsou věci WDDM, ale ty samozřejmě vyžadují i podporu ze strany hardwaru. A co je nejrozporuplnější, DX10.1 dle vyjádření Microsoftu vyžaduje "...ability to select the MSAA sample pattern for a resource from a palette of patterns, and retrieve the corresponding sample positions". Tzn. že čip musí být schopen podporovat taková rozložení MSAA vzorků, která po něm budou vyžadována. V tomhle ohledu nVidia od vydání neposkytla jednoznačnou informaci - nejdříve uvedli, že rozložení vzorků programovatelné je (v rámci 4-bit tabulky), následně, že programovatelné není a současná rozložení jsou neměnná a fixní... takže bude lepší počkat na oficiální info - tyto slajdy alespoň pro mě znamenají více otázek než odpovědí.

Nvidia Display port card pictured
Citace:
Nvidia's first Display Port card has been pixelized. The one we've seen has a single VGA and dual Display Ports on a bracket and the card looked like it is in really good shape.
The card was rendering 3Dmark06 just fine and we didn't notice a single glitch. The second fun part about the card is that it doesn't have an external power connector which means that this 65 nanometre chip won't need and external plug.

D8E aka G92 is dual PCB card
Citace:
Nvidia's next generation high end part will have two PCB cards. The card codenamed D8E or the one that we called G90 – G92 for months will be GX2 like.
We wrote about such a card back in March when our Cuda sources confirmed that Nvidia has such a design in plans.
Desktop 8 series Enthusiast is scheduled for first months of 2008 and will need a lot of power. It is a 65 part, or lets say it will have two chips each 65 nanometre with its own memory. This will bring back the Quad SLI concept in the game.

Kdyby nekdo nevedel, co znamena D8E, tak nV nedavno predstavila nova kodova oznaceni pro GPU. Prvni pismeno oznacuje pro jakou cast trhu je to GPU urcene, D znamena v tomhle pripade desktop, 8 znamena, ze patri do osmickove rady GeForce a E v tomhle pripade znamena enthusiasist.

Nvidia G92 is GeForce 8800 GT
9 palcov dlhá (nemá toľko náhodou aj RV670?), nejak sa to v mainstreame predlžuje. Cena za 256MB 199USD (nie je za toľko aj 8600GTS?). Škoda, že neuviedli viac, hlavne počet vypočetných jednotiek.

It seems to me it'll be 800MHz G92 versus 850MHz RV670.
G92:
core 800
16 TMUs = 12.8 G bilinear/s, 12.8 G trilinear/s
16 ROPs = 12.8 G pixels/s, 102.4 G Z/s
RV670:
core 850
16 TMUs = 13.6 G bilinear/s, 6.8 G trilinear/s
16 ROPs = 13.6 G pixels/s, 27.2 G Z/s
G80-GTS:
core 500
24 TMUs = 12 G bilinear/s, 12 G trilinear/s
20 ROPs = 10 G pixels/s, 80 G Z/s
64 SP G92 needs to run its SPs at about 1.9GHz to retain the ALU:TEX ratio of 8800GTS (500v1200 upgraded to 800v1920).

NVIDIA 8800GT based on G92 core Early Specs
Citace:
For those who are interested in G92 core, the first card will be the NV 8800GT card. This card will come with a core clk of 600MHz and memory will be at 1800MHz. The memory width is at 256 bits. There will be two models, one with 256M and another at 512M. It will replace the 8800GTS-320.
This model is to fit the gap in between the 8600GTS and 8800GTS. Thus the performance levels should be around there. It is said that it targets the RV670 and the performance of it should be slightly better than the RV670..
It is slated to launch on 12 November 2007.

G92/ D8M launches on the 29th
Citace:
Nvidia nailed the decision to launch G92 aka D8M on the 29th of October, a whole two weeks before it was previously reported. The chips are ready, the boxes are in production and it will all be ready for the launch on one of the last days of October.
At this time there are no implications when will Nvidia launch D8V, aka G98, but it shouldn't be be that far away from this day. The high end comes next year as a dual card.

More three-way SLI info
Citace:
We've got our hands on a page of a presentation about three-way SLI and it looks like it won't have as much to bring to the table as normal SLI does in terms of performance increase.
As we don't know which benchmark or how it's represented in the graph below, it's hard to draw any real conclusions apart from the fact that it'll be faster, which is a good thing.
It doesn't seem to add a full cards performance, but if you compare the size of the graphs you'll notice that the third card adds a bigger bit to the graph than a second card seem to do.

Geforce 8800GT is now G92/ D8P (Performance)
Citace:
What a mess. IN the same document Nvidia uses D8P (Performance) codename as well as G92 for the Geforce 8800GT. It turns out that D8M is G98 a entry level chip.
The new card is indeed a single slot and will need a single 2x3 connector. It has two Dual DVI-I ports as well as HDMI and HDTV-out support. One of the other important things is that this new chip is 65nm and that the board will eat up to 110W which is more than twice better than what R600 needs.
It is a 9 inch single slot board and it looks like it will be introduced on the October 29th but this date can change easily

GeForce 8800GT (G92) Scored 10769 in 3DMark06
Citace:
More details have popped up and we learned that GeForce 8800 GT (G92) will be clocked at 600MHz core and 1.8GHz memory. However Nvidia might still further increase the core clock depending on how Radeon 2950PRO performs. The reference score provided by Nvidia to the partners is 10.8K in 3DMark06 or to be exact 10769.

GeForce 8800 GT Overclocking Is Good
Citace:
We heard the overclocking headroom for GeForce 8800 GT is pretty impressive mainly due to the finer 65nm process technology. However, Nvidia has purposely limits the core clock at 600MHz so its performance won't get too close to the GeForce 8800 GTS thereby hurt its sales. However, users can still choose to overclock the core and we should be seeing more than 700MHz easily.

Re: G80 - G90 a dalsi novinky
Nemyslim, ze zrovna za tohle muze nejak RV670, tyhle cipy jsou podle vseho porad 90nm G80, takze kdo vi, jak dlouho ta karta bude opravdu na trhu. Prirovnal bych to k soucasne 2900Pro s 512-bit sbernici, jen kvantita bude asi vetsi.

Geforce 8800 GT doesn't do DirectX 10.1
Citace:
Documents seen by Fudzilla indicates that G92/D8P aka the Geforce 8800 GT is not Shader model 4.1 compatible. It can mean one of two things, one, that Nvidia doesn't want release the information or two, simply that this chip doesn't have support for Shader model 4.1 and DirectX 10.1.
This comes as an interesting surprise as we know that the RV670 aka the Radeon HD 2950 series will support Shader model 4.1 and DirectX 10.1.

Nvidia can't keep up with demand
Citace:
Nvidia could not keep up with the quantity of orders that they've had in the last two quarters. AMD has failed to offer a high end killer card and as such Nvidia had more orders that they expected.
This lead to a chip shortage and this upset a lot of Nvidia partners. Upset is a light understatement as the Nvidia only partners are furious as Jeff the Fish, the boss of the sales team and Fiona, the boss of the European sales department couldn't fill many of their orders.
This is actually a good thing for Nvidia's stock, as Nvidia claims that it has never sold more chips, but it's still not good in the long term. as the company has managed to upset most of its supporters.

Skóre G92 (a teda aj RV670) sa mi nezdá, lebo CJ na Beyond3D spomínal skóre G92 okolo 9000.
BTW: Tento príspevok som tu už raz mal, ale niekto mi ho asi zmazal. Taktiež som to dal do vlákna o RV670 (pre istotu, niektorí užívatelia nemusia čítať vlákna o nVidii a naopak).

No jestli RV670 opravdu da pres 11k, opravi par bugu co byly v R600 a nasadi cenu nekde kolem 8k za 512MB verzi, potom to bude asi trhak jako kdysi byvala 6800GT/6600GT nebo dnes X1950Pro.

No jinak:
Citace:
RV670 is expected with a retail price between 229 and 279 dollars, but we would not be surprised if a low-clocked part would retail for 199 Dollars/Euro.
U RV670 se bude cena podle typu pohybovat od 279/229 az k 199USD. Coz vzhledem k vykonu(nekde pry i lepsim nez R600) bude celkem neuveritelne.
Re: G80 - G90 a dalsi novinky

A zbavovat se skladových GTS úpravou 96SPs->112SPs půjde asi dost těžko, protože nic takového není realizovatelné. Pokud se čistí skaldy, tak vždy vydáním pomalejšího produktu. Nikoli rychlejšího.

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. So if you launch a new product that is faster than a 8800GTS, no one will buy the more expensive GTS unless you up its stream processor count for higher performance.

Osobne si ale myslim, ze RV670 bude lepsi kauf. ATi si muze dovolit nizsi cenu (55nm a 256bit, PCB podobne X1900) a vykon bude prinejmensim srovnatelny.
