EVGA GTX275 CO-OP Detailed Features

The EVGA GTX 275 CO-OP PhysX Edition is the first dual GPU video card to use different GPUs: there's a GTX 275 and a GTS 250. You cannot connect a monitor to the GTS 250; in fact, you can't use the GTS 250 for rendering at all. Both of the DVI connectors on the rear of the card are connected to the GTX 275. The GTS 250 is only available for CUDA work. But what is CUDA? We'll get to that in a later section.


The back of the card provides an exhaust for the heat sink cooling the GTX 275.


Removing the shroud covering the cooling mechanism reveals the twin heat sinks, one for the GTS 250 (towards the rear of the card) and one for the GTX 275 (towards the front of the card). The heat sinks are aluminum with two copper heat pipes each. They rest on thick aluminum base plates and are quite heavy. While these radiators look large, they're actually much smaller (individually) than you'd find on a single-GPU GTX 275 card.


Stripped of the radiators and plastic support plate, the EVGA 012-P3-1178-TR model finally reveals its twin GPUs:


As mentioned above, the two NVIDIA GPUs are completely separate and do not directly interact, unlike most dual-GPU cards where SLI or Crossfire technology is used. The GTS 250 has 384 megabytes of dedicated GDDR3 memory:


...while the GTX 275 has 896 megabytes of dedicated GDDR3 memory:


EVGA advertises the 012-P3-1178-TR model has having 1280 megabytes of memory, but it's important to remember that this is not any sort of unified buffer; the memory for the two GPUs is completely separate.

I'm sure that in the future ATI will eventually have cuda and physx and still outperform Nvidia with cheaper prices. So I would'nt waste my money on a Nvidia card right now, especially when their prices are much higher. Nvidia is behind and the only thing they have is its cuda and physix.
