The fact that Titan Z consumes significantly less power than a pair of GTX 780 Ti cards in SLI, despite having 2x the RAM, also tends to favor this explanation. Pros: Amazing card and the design behind making this card is great. A mammoth eight gigabytes of memory and more than 11.5 teraflops of computing power help this card do what it was built to do: be the undisputed graphics champion. Nonetheless, this kind of corner case - multiple GPUs in a dev system designed to pack as much CUDA-crunching power into a single rig as possible - is the only use case I can plausibly construct for the GTX Titan Z. AMD Radeon R9 295X2 8GB and R9 290X 4GB Video Cards in CrossFireX We throw a HIS Radeon R9 290X 4GB in with the new R9 295X2 8GB and see what kind of magic we can make happen. The AMD Radeon R9 295X2 graphics card is the worlds fastest, period. Some of you disagreed, pointing out (correctly) that such customers would almost certainly adopt Tesla-based products instead of a GeForce GPU. That’s the Titan Z’s greatest strength - it packs more double-precision firepower than any other single card you can buy. From this perspective, Titan Z offers double the GPU power and full-speed double-precision. An eight-slot motherboard could conceivably deploy two Titan Zs with three slots for each card, while the same motherboard could only mount two Titan Blacks in the same configuration. When I first wrote up the announcement, I opined that the only way this card makes sense is if it’s meant for rack deployments. GTX 780 Ti These results are fairly expectable given the Titan Z’s clock rate, but it illustrates just how badly Nvidia miscalculated Titan’s positioning and price point. Average overclock on air, water, cascade or liquid nitrogen. 3D APIs: OpenGL 4.3, Direct3D 11.2, Mantle.Memory: 8GB (2 x 4GB) GDDR5 1250MHz real speed or 5000MHz effective, 2 x 512-bit.

GPU: two Hawaii XT (GCN 1.1) 1018MHz boost clock.

This liquid cooler is a required mean to dissipate the 500W produced by this dual-GPU card. The R9 295X2 reference board comes with a liquid cooling solution based on Asetek technology (check out this press release). AMD has launched (actually the card will be available in two weeks) its new behemoth: the Radeon R9 295X2, an ultra high-end graphics card that features two full Hawaii GPUs (the same GPU that powers the Radeon R9 290X).
