Galaxy shows off dual GeForce GTX 470

Nvidia's GeForce GTX 470 and 480 cards have already picked up a reputation for being hot and power-hungry, but it turns out that some graphics card makers are already working on marrying up two Fermi chips on a single PCB.

Hot Hardware has snapped several shots of a card called the Galaxy GeForce GTX 470 Dual at Computex, with a label that describes the card as a "2x GTX 470 prototype."

The site says the card has a length of approximately 12 inches, and the pictures show that it is indeed wearing two massive Nvidia GF100 chips, each of which is surrounded by eight DRAM chips. Meanwhile, a bridge chip sits in between the two chip in the middle, and three DVI ports can be found on the back.

What caught our eye, however, was the codename on the chips. Galaxy might describe the card as a "2x GTX 470 prototype," but the GF100-030-A3 code on these chips is the same as the code on Nvidia's recently launched GeForce GTX 465 chip. Comparatively, GTX 470 chips feature the GF100-275-A3 codename.

What's more the 1280MB of RAM found on GeForce GTX 470 cards is spread out over ten 128MB GDDR5 chips, rather than eight. Comparatively, the GeForce GTX 465 has 1GB of RAM spread out over eight 128MB chips, which suggests that this dual-GPU card is really a 2GB dual GeForce GTX 465.

Of course, this is just a prototype, and we have no idea if it even works. It may be that Galaxy built a dual GeForce GTX 465 card for testing, but that the finished article will feature two full-spec GeForce GTX 470s. In fact, maybe Galaxy has plans for both a dual GeForce GTX 465 card and a dual GTX 470 card in the future.

Either way, it looks as though this is going to be a power-hungry beast. The card in the photos features two eight-pin PCI-E power connectors, and two Fermi chips are going to generate a lot of heat when they're working together.
