The Comeback Kid - NVIDIA GeForce GTX 295 Full Review

First previewed less than a month ago, the new twin-GPU GeForce GTX 295 is NVIDIA's latest flagship card. Its conception follows closely that of NVIDIA's earlier dual-GPU offering, the GeForce 9800 GX2, and that can be seen from the GeForce GTX 295 two PCB design. Rather than follow ATI's lead and squeeze two GPUs on a single PCB, what NVIDIA is doing here, instead, is to squeeze two PCBs, one GPU each, into a single card. It would therefore not be wrong to call the new GeForce GTX 295 a sandwich.

As mentioned in our preview, the GeForce GTX 295 employs two GPUs that boast specifications that are in between the current single GPU flagship, the Geforce GTX 280, and the less powerful GeForce GTX 260 Core 216 (GTX 260+). To be more precise, it has 240 processing cores, the same number as the GeForce GTX 280; whereas the memory bus width and clock speeds follow that of the GTX 260+, which means it has a 448-bit wide memory bus, and clock speeds of 576MHz for the core, 1998MHz DDR for the memory and 1242MHz for the shaders.

NVIDIA was very fussy about what we could and could not test with their new flagship, and so the preview was limited to only a number of tests. However, now that the GeForce GTX 295 has been officially announced, we have free rein to do what we want. Plus now we've newer drivers to showcase the latest results.

To refresh your memory, and for the benefit of those who haven't read our preview, the GPU-Z readings tell you exactly what's underneath the GeForce GTX 295. The table, on the other hand, shows you how the GeForce GTX 295 stands up to the competition.
