NVIDIA novinky

[Haste]

Asi jsem byl ohledně data vydání G80 až příliš optimistický... zdá se, že vyjde později. Navíc prý výrobci tvrdí, že je možné, že G80 bude používat vlastní externí zdroj pro napájení...

No k tomu zdroji to je jenom na:
A k tomu datu vydani, ja to rikal

Kazdopadne mi to(a asi ne jenom me) delaji obe firmy cim dal tezsi udrzet s nima krok v chlazeni kompu, aby se z nej nestala kvicici bestie u ktere se neda pracovat

MSI jumps the gun with 7900 GTO

WE HEARD about a new Nvidia card that is supposed to be launched shortly. It is called the 7900 GTO and will be based on the G71 chip.

It looks like Nvidia has good yields on that semiconductor. The 7900 GTO won't be an OEM/ODM card only - it will be sold through retail as well.

MSI already lists this card on preorders for €231

http://www.theinquirer.net/default.aspx?article=34400

Tak to vypada, ze nakonec tahle karta bude dostupna uplne normalne a nejen pro OEM trh a par kousku pro Oc.uk.
Jadro bude taktovano na 650MHz a 512MB pameti pobezi na 1220MHz

NVIDIA's PureVideo HD Interview and Experiences

9. Why are there different codecs being used for Blu-ray and HD DVD movies? Will PureVideo HD play all of them?

HD DVDs and Blu-ray both support three different codecs – H.264, VC-1 and MPEG2 HD. The movie studios make their choice of codec based on economic and time to market factors. The studios have been producing DVDs based on the MPEG2 format for years, so there is an entire authoring and duplication infrastructure in place that can turn out MPEG2 encoded high definition movies very quickly. MPEG2 HD movies take up a lot of space though and don’t leave much room on the disc for special features. VC-1 has a higher compression ratio than MPEG2 and has been an early favorite for U.S. movie releases. H.264 has an incredibly high signal to noise ratio (meaning great images) and provides excellent compression, but since it is a fairly new standard, the infrastructure to support it is still maturing. PureVideo HD provides hardware accelerated decoding for H.264, VC-1, MPEG-2 HD, MPEG2 SD and WMV.

NVIDIA unveils world's first 80 nanometre graphics chip

The GeForce Go 7700 features 12 pixel processors and operates at 450MHz, 128-bit memory controller, up to 512MB of memory at 1000MHz clock-speed. Given that Nvidia’s web-site has one page for the GeForce Go 7600 and Go 7700 models, it is highly likely that there is no difference between the GeForce Go 7600 and GeForce Go 7700 apart from manufacturing process – 80nm for the Go 7700 and 90nm for the Go 7600 – and some performance differences.

According to Nvidia’s web-site, the Go 7700 is faster compared to the Go 7600, but is not as fast as the Go 7600 GT model. There are no approximate thermal design power differences or power consumption differences noted by Nvidia, even though thinner fabrication process usually means a bit lower energy consumption. Additionally, thinner manufacturing processes allow developers to manufacture the chips in a more cost-efficient way, which may benefit end-users in terms of lower pricing.

Zvlastni, clovek by rekl, ze prvni s kartou na 80nm prijde ATI

[Masster]

From someone I trust:

- 40% dedicated to D3D10 (a little unclear if this means of the entire die).

- NDA expires beginning of november.

- Hard launch.

- Aims for good availability for 3 SKU's for chrismas sales.

Nevim jak presne si vylozit prvni informaci, ale zbytek je dost jasny. V listopadu se mame na co tesit.

[Masster]

Dalsi rumours:

- zprava o spotrebe 175W na kartu je mylna - bohuzel nebylo receno v jakem smeru, ale podle drivejsich zprav Ing je klidne mozne, ze je to i malo

- v prvni varce bude dostupnych asi 40k kusu

- G80 ma v 3DMarku dosahovat vykonu 2x7950GX2 a neni myslen vysledek v QuadSLI

No pokud bude mit R600 zpozdeni a vyjde o par mesicu pozdeji, tak bude mit ATI mozna slusny problem. Koluji totiz dalsi zvesti o G80 na 80nm, ktera by se mohla objevit kolem unora/brezna.

[Haste]

No predevsim podle rumours co sem cetl me G80 pomalu prestava zajimat, ale snad se myli. Ten navrh 20x20mm chip, ktery by mel byt rozdeleny na 48pipelines na DX9 a 48pipelines na DX10 s 384bit memory controlerem me celkem desi Snad je to jenom vymysl Inquireru...tentokrat v to opravdu doufam...

A řekl by správně. Většina výrobců na X1650PRO dává 80nm RV535, který jsou dostupný už od začátku září. Jen kolem toho ATi nedělala takovej povyk

Jenze kupujes zajice v pytli, kdezto u nV mas jistotu.
To je myslim trosku rozdil.

[no-X]

Tys mluvil o prvním 80nm GPU... me o podobě, v jaký je dostupný. Krom toho to jako zajíce v pytli nevidím - někteří výrobci používají jedno jádro, někteří druhé (např. všechny PC X1650PRO mají RV535)

Two models at launch : GeForce 8800GTX and GeForce 8800GT
GeForce 8800GTX : 7 TCPs chip, 384-bit memory interface, hybrid water/fan cooler, water cooling for overclocking. US$649
GeForce 8800GT : 6 TCPs chip, 320-bit memory interface, fan cooler. US$449-499


Our friends have gotten some information of the upcoming NVIDIA G80 and it appears that G80 gonna be unified shader after all. It should be pretty close to the truth and it explained the mystery of the strange DRAM capacities that INQ reported previously. Expect G80 to be out somewhere in mid November along with Kentsfield.
