Are they DX10 certified?

[sulky_uk]

couldnt find that on the site, i think that theyll wait untill nearer dx10's release date to tell us its not a dx10 card

Sounds somewhat strange to me, especially the amount of memory and the bitrate of it. Sounds like they're talking about 2 processors on the card, with one using 512MB mem at 265 bit and one using 256MB at 128 bit. Mebbe GPU and PPU on the same card? Either that or it's a fake.

That being said, if it is real it'd almost certainly be a DX10 part. With games like Crysis already in development requiring DX10 do you think they'd release another generation of graphics cards that aren't native DX10?

Tho... if DX10 is (as I seem to recall hearing) not going to be backwards compatible with DX9 and previous (requiring devs to write 2 complete versions of the engine, one for DX9 and previous cards and one for DX10), and with DX10 not coming out for XP, only Vista (once again, or so I have heard), would a DX10 native card only be compatible with Vista?

You raise an interesting point to which I don't have the answer. I wonder how much bloat ware Vista is going to be?

PS those of you that have tried the beta's, how well does Vista handle 32 bit progs if at all?

got the offical vista rc1 and everything i throw at it works atm<_<

From what ive found out by now its a single chip card...
ANd for the momery interface, sounds like they are using a new tech they developed called SBL which apperently should increase the throughput a lot, dunno how exactly its works but ill have a look around on the web...
But as for them being fake, some is prolly fake and some of it not
Im 95% sure that the card is WFG (DX10) ready imo...

[kregoron]

ive been looking around about the amount of memory... and another thing the weird memory amount might be cause by is... that a DX10 card wont run DX9 api applications... so it seems bliz made so its actually two cards in one... therefore the memory... 512mb for DX10 256 for DX9 applications... about the core and the DirectX 10/9 issues i will try to investigate a bit more...

[Carr0t]

so it seems bliz made so its actually two cards in one...

I think too much WoW has addled your brain dude. Blizz don't make gfx cards :bleh:

[Gorion]

got 2 pics of this card, one with watercool and the other fan. forgot the hosting site ppl use tho

Errrmmmm you are prolly right about that

*update*
Dailytech now reveals, that G80 will support 128-Bit High dynamic range (HDR) and Antialising with 16x sampling. Current cards use 64bit HDR.
THe new High Dynamic Range is originally developed by Industrial light and magic.
So we will have 128bit floating point HDR, as soon as the programmers gets it implemented. As some might already know, nVIDIA sli setups already AA at 16x sampling, but with the new G80 this will be possible with a single card.
These two new features will be a part of a new engine comparable with "Purevideo" and the brand new "Quantum Effects engines" which has something to do with Physics calculation.
 
 
 
Ill try to get some more correct info about how the new ram system works... lots of rumors are in the air atm..

[kregoron]

I just found yet another rumour about the new ram system..

ill try keep looking till i find some place where they got some validated info of some kind

Geforce 8800 Series Preview

On 8th November nVIDIA will present the next generation graphics card to the multimedia community, the Geforce 8 (notice how I didn't use gaming community).
nVIDIA just delivered the first DirectX 10 Graphics card, the Geforce 8800GTX as well as its sibling, the Geforce 8800GTS to its partners & review sites. Sadly we only have two days to tinker/probe with this special card.

I know many of you are expecting graphs and benchies (something which is annulled by the NDA), so let’s get out the obvious out of the way. The 8800GTX is approcimately 30-40 per cent faster than ATIs current Radeon x1950XTX. This percetile increases dramatically as the resolution increases. The performance of the Geforce 8800GTS is on par with ATI’s highend cards, if not faster. As usual these percentiles WILL increase as nVIDIA optimizes and releases a new version of its Forceware drivers.


SPECS
Geforce 8800 GTX | Geforce 8800GTS
Price: 650 euros | 500 euros
Transistor Count: 700 million | 700million
Manufacturing: 90nm | 90nm
GPU Clock: 575mhz | 500mhz
Shaders: 128 | 96
Shader Frequency: 1350mhz | 1200mhz
Theoretical fill rate: 36800 mpix/s | 24000mpix/s
Memory Size: 768mb GDDR3 | 640mb GDDR3
Memory Clock: 1800mhz | 1600mhz
Memory Interface: 384bit | 320bit
Memory Bandwidth: 86.4gb/s | 64gb/s


The Card: 800grams, 260mm long & PSU hungry

The highend GTX model is quite an oversized card, having a full sized PCB of over 260mm. Its huge 2 headpiped heatsink (which works quite well and silently) increases the weight by over 800grams. Power wise, the 8800GTX needs 2 (yes two) 6pin PCI-E connectors. PCI-E lots can give upto 75W, whereas the 8800GTX needs 200W in total, hence the extra connectors. nVIDIA recommends a minimum of a 450W PSU with 30A on its 12V rail. This is only a recommendation since we can’t think of a PSU which has 30A on one 12V rail. Most new PSUs have multiple 12V rails with 15 to 22A rails each and these should run the 8800 quite well.


700,000,000 (700mil!) transistors, Unified Shader Architecture, Quantum Physics Processor & More

The new Geforce 8 cards literally DOUBLED the transistors count that any previous graphics card has. The weight champion before was the x1950STS, having ‘’only’’ 384mil. This dramatic transistor count increase was put to use well by nVIDIA since it gave them the chance to enable a unified architecture. Older cards had specific number of pixel and vertex shaders, whereas a unified architecture (128 in the GTX, 96 in the GTS) gives a much better sense of complex coding for game programmers, giving the gamers a better looking game.

Onboard the geforce 8 cards, a PPU is in place, called the Quantum Effects Physics Processor, which takes care of the physics in games, specifically those coded on the new HavokFX Physics engine.

HDR + FSAA was only available for ATI x19x00 cards, but not anymore. The 8800 series adds this feature, together with 128bit HDR and 16X FSAA, which is drop dead gorgeous. Such features will be used considerably in games such as Alan Wake (DX10 game, Q3 07)

The clockrate on the 8800GTX is 575mhz, 75mhz lower than the previous nVIDIA 7900 flagship card. Memory is clocked at 1800mhz (1600mhz for the GTS). The working frequency for the shaders is 1350mhz for the GTX and 1200mhz for the GTS, giving us a 36800mpix/s and 2400mpix/s theoretical filling rates respectively. Fear not, nVIDIA has Gigapixel Technology which is feasible thanks to the new unified shader architecture. Even though the memory clockrate is low, it is based on a 384bit memory interface (past cards had 256bit memory interfaces), giving the 8800GTX a healthy 86gb/s memory bandwidth. The GTS has a 320bit memory interface with a memory bandwidth of 64gb/s

As anyone can notice, nVIDIA is making sure the GTS can never surpass the GTX, even if overclocked. This is achieved by having a different shader memory clockratem which the standard memory clock is the same 1.6ghz. Also, let’s remember the missing 32 shaders.

Both cards support DirectX 10, OpenGl 2.0 and support SLI. The dual link DVIs are HDCP hence digitally protected movies (in 2010/2 lol) can be seen without any problem from HD-DVD and Blu-Ray sources.


Counclusion

Both the Geforce 8800GTX and 8800GTS will be available in leading stores on November 8th (perhaps 11th for Europe) with a price of 650euros and 500euros respectively.

While not exactly cheap, the GTX is currently the only way to get 10k in 3dmark06 using just a single card, even though ATI’s forthcoming R600 card might (and will imho) end up slightly faster..unless nVIDIA wips up a special foreware (wink wink). And no, we're not breaking any NDAs…not yet anyways
