G80 pictures reveal a second RAMDAC processor

zekrahminator · Oct 29, 2006

Pictures of the NVIDIA GeForce 8800GTS and 8800GTX show what looks like two graphics processors. However, the smaller second chip is dedicated to "NV I/O".

It turns out that the small chip on the Geforce 8800 cards is an Nvidia NVIO chip. It provides dual 400MHz RAMDAC and Dual - Dual Link DVI output, TV Out and HDCP. Our informative friends call the chip External Video I/O Chip or simply External RAMDAC. We don't have any idea why Nvidia needed that, as RAMDAC has been normally part of the chip for generations.

There are also specifications showing the power requirements for the NVIDIA GeForce 8800GTS and GTX. The 8800GTS will require 26 amps on the 12 volt rail, and the 8800GTX will require a whopping 30 amps on the 12 volt rail. The 8800GTX also has a second SLI bridge, which may link to a future physics solution from NVIDIA.

30 amps?^^ what will quad sli then be?
4x30 amps?
a bit much or what? and what cpu can feed 4 of this cards

Chewy · Oct 29, 2006

will the OCZ GameXstream 600watt sli/cf be good enuff to run one of theses? it has quad 18 amp rails, I'm guessing its just enough.

Edit: Thought I had posted this already, the 4 rails would have like 56 max amps so 18 +18 = 36 leaves 20amps for the system and maybe some room for an overclock.

I'll prob get one of theses suckers in a years time, hoping my 1900gt will be enough for now.

thats some power requirements

NamesDontMatter · Oct 29, 2006

that cards pretty damn big too.

lol yeah, they'll have to start GeForce 8 series certifying cases to let you know they can accommodate them :laugh:

I don't see the point in DX10 hardware atm though, dx9 will still be supported for a long time and first generation hardware is always a bit iffy. I'll stick with my X1900XT until lots of games start coming out that would make having dx10 a real advantage

The second SLi bridge is for SLi... Just like ATi, nVidia are moving to two-way transfer of information... Less stress on the PCI-E channels means better performance system-wide...

wtf8269 · Oct 29, 2006

Looks like I'll either be needing to take my hard drive cage out again or get a new case, and definitely get a new PSU. Yay for black PCB though!

i_am_mustang_man · Oct 29, 2006

quick ? - 30amps on the 12v rail, but is that 15amp per plug? cuz it's a two plugger.... idk much about the whole rail thing, just want to know enough that it won't explode when i plug it in

Tory · Oct 29, 2006

You guys are misunderstanding the amps requirements. That's 30A for the whole computer, not the video card. And remember they have to leave lots of room for tolerance so you could probably get away with a nice 380watt PSU for the whole system.

cdawall · Oct 29, 2006

can you say boom on a cheap psu the cards sound like each will need its own psu

i_am_mustang_man · Oct 29, 2006

you'll need one of those thermaltake pure power express front drive bay thingies for each card! that'd be pretty sick actually...

pt · Oct 29, 2006

i have few words to say:
BAH, to dx10, vista, and dx10 cards :shadedshu
:slap:

RickyG512 · Oct 29, 2006

have u forgoten that the X1900XT is 30 AMP and crossfire is 36 AMP

dj_dn · Oct 29, 2006

I am not switching until they fix this stupid high power consummation. Come on, that card will suck 360 watts of power, that’s bull. They need to work on that. House breakers can take 15 amps, so that’s 1800 watts at 120 volts. So if they keep this up we’re going to need a breaker for the computer.

roll on 2kw pc's.2x8800gtx,oc'd 6800extreme.2kw power supply please lol.

nah
3kw

2x8800gtx+phisycs
quad core
4gb of ddr2
Nvidia 680i
4hdd's
xfi sound card
case with lots of fans

:toast:

Canuto · Oct 29, 2006

I'd say Prescott instead of Quad core...

Tory · Oct 29, 2006

I'm not going to bother trying to convince you guys anymore. When it comes out you can run it on your 1KW PSU and I'll run it just fine on my 430watt PSU.

nah, a intel extreme edition :nutkick:

(overclocked)

Prescott extreme edition OC'ed...

strick94u · Oct 30, 2006

Just when we get past cpu bottle necks bam a gpu that will need more and more it has 2 psu connectors weeeeeeeeeeeeeeeeeeeee.........................so all you will need is a new case(size) psu (volts/amps) and a faster more powerful cpu. sure we can get by on what we have but.Ok sell your car and your present pc and build a new pc makes me wonder how much longer we can build our own what with vistas new rules and all :ohwell:

SkylinGTR26 · Oct 30, 2006

...meh, i dont think the man will ever be able to stop us from building our own PCs.
They might take away the OS that we have to use, but theyll never take our freedom in building our own custom cheap PCs.

Never EVER!!!!
some please second me!

Pay attention class:

The 30a power requirement is for the whole computer, not just the video card. The current high end cards on the market have very similar requirements, so shut up if you don't know what you are talking about.

I sure hope so, only reason I'm not sure is because of DX10 being known for hot parts and the second power dongle on the 8800GTX
