A reader just sent in this amazing “NVIDIA Human Head Demo” clip, which is basically a “real-time rendering of Doug Jones (Hellboy, Pan’s Labyrinth, Fantastic Four: Rise of the Silver Surfer), rendered on the new GeForce 8800 Ultra graphics card.” Video after the break.
To je husty, fakt nadhera. Jen by me zajimalo jak dlouho trva vytvoreni takovehodle obliceje, potazmo vyvoj her, ktere by obsahovaly takle detailni objekty. A kolik pak budou takovy hry stat...
Podle me lze tohle vyrobit na 1-2rok stary karte..akorat real time render in game,to by chtelo neco 5X rychlejsiho nez G90 s 5GB pameti :)
Jinak moc pekny..
Ale vzdyt je to real time render...
Jenže se to nehýbe, nemluví a nemrká... ;)Citace:

A navic je to jenom hlava. V hre toho obvykle byva vic:-)
Nicmene je to moc pekne:-)
O to se uz bude starat Ageia (fyzikalni adapter) :)Citace:

Good news for users of Vista, the 158.42 Driver will be on there website on May 14th
This driver adds support for:
- Improved single GPU and SLI performance
- NVIDIA SLI on DirectX 10
- Compatibility fixes on numerous applications
Human Head Demo Available

To evaluate the complex skin shader and HDR lighting, "Human Head" computes 17 offscreen textures every frame totaling over 40 Million pixels, each shaded with lengthy pixel shaders. That's more than 1.2 billion pixels every second! 4096 x 4096 color and normal textures provide photo-realistic detail even at extremely close ranges.
NVIDIA confirms Next-Gen close to 1TFlop in 4Q07
http://www.beyond3d.com/content/news/230Citace:
In recent analyst conferences that were publicly webcast on NVIDIA's website, Michael Hara (VP of Investor Relations) has claimed that their next-generation chip, also known as G92 in the rumour mill, will deliver close to one teraflop of performance. In a separate answer to an analyst's question, he also noted that they have no intention from diverging from the cycle they have adopted with the G80, which is to have the high-end part ready at the end of the year and release the lower-end derivatives in the spring.
Assuming that NVIDIA manages to hit these aggressive release schedules, it implies that the chip will compete with any potential R6xx refresh at the beginning of its lifetime, but also eventually with R700 as it seems unlikely NVIDIA will refresh again before the second half of 2008, unless they go for an optical shrink from 65nm to 55nm. It also remains to be seen how aggressive ATI will be on the process front this time around.
lol tak podobne som cital akurat tu neviem ako to chcu ati dobehnut :D ved vzime vydaju len r650

G92 rumour spec.
http://www.pcdvd.com.tw/showpost.php...7&postcount=29Citace:
65nm
approximately 1000M Transistor Count
Two times of Raw performance of G80
Die Size :3/4 of Die Size of G80
Shader Clock of G92 is much higher than that of G80.
3 or 2.5 times of Factual Performance of G80
Due Launch Date : End of Nov
Hmm pokud se nV zadari a vyda ji v planu ,tak asi ATI v high endu dobojovala ,protoze R650 stacit nejspis nebude. To neni ale vubec dobre.
Část z toho pravdivá je, ale celkově ty čísla nedávají zas až takový smysl. Přechodem z 90nm na 65nm se při zachování plochy může navýšit počet tranzistorů o 50%. Protože má být ale G92 jen 3/4 plochy G80, odpovídalo by to nárůstu o 25%. Odkud by pocházel ten o 2,5-3x vyšší výkon? Takový rozdíl nepřinesla ani G80 jako zcela nová architektura - popravdě, když u nějakých "specifikací" bývalo psáno výkon 2-3x vyšší, byl to zatím vždycky fake. Takže pokud by se nVidii povedlo vydat čip, který by v reálných aplikacích byl v průměru "jen" 2,5x výkonnější, tak smeknu a koupím si ho.
Spíš si ale myslím, že vzhledem ke zmenšení plochy jádra (=primární pro nVidii je spotřeba a odpadní teplo, nikoli výkon, jinak by nešetřili plochou) půjde o řešení a la 7950GX2, tedy dva čipy na jedné kartě. Pak by bylo možné 2,5-3x vyššího výkonu v některých situacích dosáhnout.
S 25% tranzistory navíc se moc kouzlit nedá. Vytahnout počet TMUs na 48(x2) a shader core jen nataktovat výše (třeba 2500MHz)? Nebo nechat počet TMUs a rozšířit shader core na 160 či 192 ALUs?
Podle mě by bylo nejmoudřejší vykašlat se na TMUs s duálním texture-filtrem - je sice hezký, že trilineární filtrace je díky tomu bez ztráty výkonu, ale při spoustě operací (a zvlášť pak v některých pro DX10) bude půlka filtering units ležet nevyužitá. Takže pokud by místo toho implementovali 48 klasických texturovacích jednotek, stálo by to možná stejné množství tranzistorů (o 16 filtering units méně a o 16 adressing units více) a výkon by to dalo - obzvlášť v DX10, vyšší (řekl bych, že i v DX9). Propad výkonu při AF by byl sice větší, ale zároveň by byl větší i výkon bez AF (je lepší mít 85FPS bez AF a 75FPS s AF, než mít AF bez ztráty výkonu a být tak či tak na 70FPS). Tím by se zvýšila efektivita texturing enginu bez nároku na tranzistory, další texture fillrate by se dohnal frekvencí a těch 25% tranzistorů navíc by mohlo padnout čistě na shader core (třeba 192SPs)...
už se těšíme :) :cool:Citace:

Nvidia's D8M taped out
http://www.fudzilla.com/index.php?op...=1420&Itemid=1Citace:
Nvidia has already taped out its next generation mainstream chip. It calls it D8M where D stands for Desktop and M stands for Mainstream and number 8 indicates that we are talking about an 8th generation product.
We can confirm that we are talking about 65 nanometre chip and that it supports PCIe 2.0 interface. Intel is already coming with X38 chipset in Q3 that will support PCIe 2.0 and AMD has already showcased its Rx7x0 generation of chipsets that can support PCIe 2.0.
We are sure Nvidia has a chipset with PCIe 2.0. The chip also supports HD DVD and Blue-Ray hardware acceleration as it features 3rd generation Video processor.
Nvidia's new card will feature internal S/PDIF on board the graphics card on a reference design and Zotac has that even with G86. We wrote about it here and even tested the card here.
G92 is 65nm and 256-bit memory bus?
http://www.vr-zone.com/?i=5092Citace:
We heard about an upcoming GPU from NVIDIA on 256-bit memory interface earlier this month and we thought it is the rumored 256-bit version of G84. Now we learned that it is actually the next generation G92, a 65nm performance part supporting PCI Express 2.0 and 256-bit memory interface. G92 performance lies between GeForce 8800 GTS and 8600 GTS so it is not the highest end GPU from the G9x series yet.

Jejda.. to asi bude dělo.. :D
RED: G92 třeba bude dělo, ale tyhle specifikace jsou fake :-)
Vypada to spis jako soupis veci, ktere jsou zname na 100% + veci, ktere uz ma R600, nez jako neco realneho ;)
btw. si stejne myslim, ze by meli pro jednu generaci vynechat GTX/GTS a dat tam Pro :mweheh:
G92 to be launched in November
http://www.fudzilla.com/index.php?op...=2161&Itemid=1Citace:
Nvidia is about to launch a new high end card and as far as we know Nvidia will launch G92, a 65 nanometre version of G80 with support for PCIe 2.0 interface and some other face lift changes.
The editor’s days are scheduled for October time while the real hardware launch is scheduled for sometimes in November.
We know that G92 will end up significantly cooler and faster from very successful G80 but we don’t have much more details. AMD won’t have any other high end card to fight this product until Q1 2008.
taky fake?Citace:

NVIDIA took graphics share from AMD last quarter
http://www.techreport.com/onearticle.x/12955Citace:
Market research firm Jon Peddie Research has published PC graphics market numbers for the second quarter of this year, and the firm says AMD's slice of the overall market has dropped to 19.5%—down from 21.9% in the first quarter. By contrast, Nvidia's overall PC graphics market share went up just over four points from 28.5% to 32.6%, while Intel's lost about a point, slipping from 38.7% to 37.6%. According to JPR, AMD's and Intel's results were more or less typical for that time of the year, but Nvidia's gains were significant.

You made so many spelling mistakes in your version Erik. Im thinking a real Nvidia source would be less sloppy.
