NVIDIA GTX 780 Review: GK110 on a Diet
Three months ago, Nvidia added the GTX Titan to its lineup. For $1,000, you could buy the first gaming-focused video card to use a GK110 chip. 6 GB of GDDR5 RAM, 2,688 CUDA cores, and a TDP of 250W make the Titan a very attractive card, but the allure is quickly overshadowed by the four figure asking price.
That GK110 chip is now available in a less expensive card, however, as Nvidia is releasing its new flagship, the GTX 780. With an MSRP of $649.99, the GTX 780 brings the price down on the GK110, bringing the oft-referenced chip closer to the mainstream. I say “closer” only because $649.99 is still a tough pill to swallow.
3 GB of GDDR5 memory, a 384-bit memory interface (as opposed to Nvidia’s usual 256-bit), 7.1 billion transistors (which makes the five billion total transistors in the Xbox One seem a bit paltry, no?), and, perhaps most importantly, 2,304 CUDA cores. On paper, the GTX 780 sits right between the GTX Titan and the GTX 680, borrowing heavily from the former while approaching the price of the latter.
Nvidia was kind enough to send me a GTX 780 for evaluation. The two most important questions I’ll answer here are, 1) Is the GTX 780 worth its $649.99 price tag?, and 2) Who should (and should not) invest in a GTX 780?
We’ll get to the benchmarks in a moment, after we talk about the design of the 780, as well as what other new tricks Nvidia has up its sleeve.
