Nvidia GeForce GTX 780 Ti Review: GK110, Fully Unlocked

An anonymous reader writes "Nvidia lifted the veil on its latest high-end graphics board, the GeForce GTX 780 Ti. With a total of 2,880 CUDA cores and 240 texture units, the GK110 GPU inside the GTX 780 Ti is fully unlocked. This means that the new card has an additional SMX block, 192 more shader cores, and 16 additional texture units than the $1,000 GTX Titan launched back in February! Offered at just $700, the GTX 780 Ti promises to improve gaming performance over the Titan, yet the card has been artificially limited in GPGPU performance — no doubt in order to make sure the pricier card remains relevant to those unable or unwilling to spring for a Quadro. The benchmark results simply illustrate the GTX 780 Ti's on-paper specs. The card was able to beat AMD's just-released flagship, the Radeon R9 290x by single-digit percentages, up to double-digits topping 30% — depending on the variability of AMD's press and retail samples."

Tomshardware is known to be biased as they take in ad money and partnerships with Nvidia and Intel. They put in x87 non IEEE FPU tests where Intels own chips win and declare anything AMD/ATI a loser as a result rather than real world performance. They do not test the later versions of Skyrim which have proper FPU support as an example in their benchmarks.

Re:TITAN has one advantage...possibly

[gman003]

The other advantage of the Titan is the double-precision performance. Almost all of Nvidia's cards, including the 780 Ti, run double-precision floating-point calculations at 1/24th the rate of single-precision, but for the Titan and the Tesla pure-GPGPU cards, it's 1/3rd the rate.

While I'm not sure if that's an actual hardware difference, or if it's some software limitation, or a mix of both or whatever, it's definitely real. That's the main reason a Titan is still $1000 - it's being sold as a low-end compute card, not a high-end gaming card.
