First Single-PCB GeForce GTX 295 Accelerator Spotted

So it is true! NVIDIA does have a single-PCB GeForce GTX 295 accelerator in the works, and partners already seem to have access to it. The card must have had some serious development put into it, given the sheer complexity of the PCB (to cram two G200b GPUs, their display processors, and the PCI-E bridge chip, along with 28 memory chips). The accelerator first surfaced in the form of CAD drawings, in March.

The PCB is pretty straight-forward: populate all the important logic on its business-side, and the memory on either sides. The card maintains its requirement for 8 + 6 pin PCI-E power input. Its VRM is spread across two main areas, to power a GPU system each. Internal SLI connects the two systems, while also providing support for Quad-SLI. Each GPU features 240 shader processors, along with 896 MB of GDDR3 memory across a 448-bit memory interface. Also pictured is the cooler: A fan nucleates the cooler, and blows in two opposite directions. The air is guided by the shroud onto two dense aluminum fin arrays that cool each GPU-system. The back of the card may use a heatspreader to cool the memory, like how the GeForce GTX 280 does it. While we don't expect this design to bring down the retail price of the card, we do believe that the design is mainly to provide partners, and retailers with decent margins that make selling the card a worthwhile venture. With the older design, it might not have been the case.

I bet the price will be out of this world and also universe. Why nvidia is doing this? Why producing expensive cards?

I think until Nvidia gets major economical hit they wont understand this strategy of making expensive cards is not the way to go.

I rather Nvidia to keep respawning G92 based cards with minor improvements than to make expensive cards like this.

same coolers as the ones on the palit 4870X2

if you notice the mounting holes on this card. no 3rd party current coolers on the market available will fit on this beast. coolers will have to be made for it :nutkick:

Yep, this thing has some seriously twisted, nonsymmetrical mounting hole patterns, even the two GPU chips have different patterns!

Wouldn't be surprised if there are a few solid capacitors exploding left and right. Only THREE phases per core... Nvidia is going to have to pull off some HDT, to cool this thing properly since it has such huge heatspreaders.

The original pictures said "Inno3d" on the card, why was that changed to just black plastic without a partners image on it?

tkpenalty,
It has just as many power phases as the original sandwiched GTX295 with each of the three spec'ed for 40A so there's enough juice to go around.

how so? there is no current card that looks like that so unless someone is really really good at making things that don't exist it looks pretty realistic
I was just being facetious lol

I was all gung-ho about this, thinking that it would be so much cheaper and easier to water-cool for those of us with a few universal blocks laying around, until I saw the mounting holes, that is. What the hell were they thinking?

They were thinking they could make a lot of money for someone by having to make everyone buy new blocks. Maybe they're going to offer custom "certified" Nvidia ones or something. :laugh:

All the next-gen junk is JUST around the corner....

Why bother advancing the old camp? - These current GPU's are a profit nightmare...

Although that's probably the whole point - reduce assembly cost by using 1 board, and try and flog GPUX2 to try and make some recovery on old stock...
Nvidia will rebadge it as a GTX375 and sell it for more, people will cry for it, will sleep with the box, will eat less for it, will sell their firstborn. All as they are Nvidiots.

Sorry for being such a noob, but the question i always ask is : Why do they have to SLI-it when they finally made it into a single PCB ?

Games stil have to run in SLI mode while the card isnt in seperate 2 PCB ...

This card will carry the name "GeForce GTX 295", no re-branding.

judging by that last pic, i'm expecting to see 775 coolers bolted on.
LOL, they do look like CPU coolers. I would not be surprised to see some one take of the plastic part and put 2 high powered fans on each block lol.

because they still need to communicate.

Uhm why ?

They need to re-brand it or somebody dont know if is it single or with 2 PCB...

Or you need always a pic for know what model is...

with nvidias last few naming schemes, you think they want to make it easy now?

How so? Can't you tell the difference between the boxy 2 PCB card, or this one? Besides they're the same accelerator by their specs anyway. Not that the 2-PCB card is faster or has a better VRM. Also we have seen proof that it retains the GTX 295 brand name, that we had to remove since an NVIDIA partner asked us to. The card's sticker read "GTX 295".

Ok understood...


Well the only advantage that people will buy this card is that it can mount a aftermarket heatsink, which are much more efficient as the original.

Rather than the old model (like mine) would be good if mounted on a waterblock.

This of course if you want silence and overclocking at same time.

The 2-PCB design's cooler is more efficient, since the central block gathers heat from the two GPUs evenly as the air flows. In this design however, the cooler will be pushing one of the GPU's hot air back into the case. Normally, cases would have air-intake fans that will blow in the opposite direction of this flow. So one of the GPUs is going to stay warmer than the other.

But mine too have one GPU warmer 2 3 degrees than the other.


I think it's the card that is on top, because the heat tends to rise and the top card holds more heat than the bottom.

That's why the EVGA backplate is a good investiment.

Some people say it is only for aesthetics but for me it helps a lot to cool the upper pcb.

That's actually a healthy difference. It's not like when I say "even" cooling that the two should have the same temperatures.

Here's an interesting graph showing the disparity of temperatures for the HD 4870 X2:

A single PCB is still better for water cooling tho. You can at least get it down to a single slot with a full-coverage block.
