NVidia GTX 780 Ti faster than GTX Titan

Question

Today the GTX 780 Ti GPU is available starting at $699 and it is faster than the $1000 GTX Titan.  We do not have any test results but all specifications point to it being faster.  It has faster memory and more CUDA cores.  The only difference is that the GTX Titan has 6 GB of video RAM while the GTX 780 Ti has 3 GB.  Unless the media you are editing is higher than 4K, 3 GB of video RAM should be enough (see Harms data).
Will someone please move this to the hardware forum, I must have been dozing off  Bill

Answer 1

The 3770k will be a great match for a single 780ti.
Maybe on an absolute scale. But in my previous post in this thread I compared to the PPBM6 results Harm's Monster achieved. (And granted, Harm's Monster was equipped with a GTX 680 when he tested it.) Thus, if my i7-3770K was 2.5x slower than Harm's Monster in the H.264 Blu-ray portion of the PPBM6 test suite (259 seconds versus 115 seconds), then the MPEG-2 DVD result should also be about 2.5x slower than Harm's Monster (in other words, a result of about 52 seconds compared to the 23-second result of Harm's Monster). However, since Harm's Monster used a GTX 680 to achieve those results at the time he tested it, it follows that the recommended GPU for my system to achieve that particular balance would have been a plain, non-Boost GTX 650 Ti.
That said, I tested a 2GB GTX 660 from eVGA (a GTX 660 SC) in both my auxiliary i5-2400 system and my main i7-3770K system, and while I do agree that the GTX 660 was a bit overkill with an i5 with only 16GB of RAM {its MPEG-2 DVD result of 40 seconds was 2 seconds slower than the same card did in my main rig although I cannot confirm whether the slower result was CPU-limited or RAM-limited (UPDATE: I investigated further, and the 2-second slower result was due to the auxiliary system's PCI-e x16 slot running at only PCI-e 2.0 instead of PCI-e 3.0 bandwidth)}, the GTX 660 would be a good match for an i7-3770K with a moderately overclocked CPU, 32GB of RAM and a two-disk RAID 0 with the latest-generation 7200 RPM disks (such as the 1TB to 3TB models in the Seagate 7200.14 line). In fact, the GTX 660 scored the same (38 seconds) as my old GTX 560 Ti 448 (which should really have been named a GTX 570 LE instead of its released name) in the MPEG-2 DVD portion of the PPBM6 test suite.
