Prefetching routines also help, and have also been improved since Kepler. Compression and optimizations in the pipe, like instruction-level interrupts, also mean faster and more intelligent processing and queuing of commands. By way of example, greater color compression in memory means power savings on every bit transacted across the bus, significantly reducing overall power consumption versus effective computational power. This key word, “efficient,” generally can be taken to mean greater performance per watt of energy expended. Modern datapath optimization, clock-gating, and compression tech (like advancements in color compression) mean modern architectures are vastly more efficient. The 780 Ti GPU hosts 2880 CUDA cores with a reference Boost 2.0 clock of 928MHz. The 780 Ti runs more cores, and while that may not be the biggest identifier of gaming performance (especially cross-generation), it is potentially a point of advantage in some production applications. This does not take production workloads into account, which may still be advantaged on the 780 Ti over some lower-end, equally-matched (in gaming) GPUs of the modern era. The point of mentioning this core architecture change is to reinforce that we’re focusing solely on gaming performance for today.

The 780 Ti and its GK110 GPU support FP64 on a 1:24 ratio (1x FP64 enabled core, effectively, for every 24x FP32 cores). Precision has also changed, with modern Pascal GPUs focusing primarily on FP32 ( short of going GP100). Depending on whether you’re looking at Maxwell or Pascal, core-to-core, there is as much as a 40% increase in performance per Watt versus the old Kepler architecture. Kepler had a vastly different core and SM architecture from today’s Pascal, and as such, the core count is not comparable to the 10-series on a strict numbers basis. The GTX 780 Ti operates on nVidia’s Kepler architecture, using the fully enabled GK110 die (including all 15 SMXs). This card came out just shortly before we really got heavy into GPU reviews, so we unfortunately have no original review to compare against – but it had about a 2-year period on our bench. In case anyone’s forgotten the specs (it’s been a while), we’ve got a recap table of the GTX 780 Ti specifications below. For today, we’re revisiting the GTX 780 Ti 3GB card for an analysis of its performance in 2016, as pitted against the modern GTX 1080, 1070, 1060, 1050 Ti, and RX 480, 470, and others. Our last revisit looked at the GTX 770 2GB card, and our next one plans to look at an AMD R9 200-series card.
GTX 780 FP64 SERIES
The 780 Ti was in competition with AMD’s R9 200 series and (a bit later) R9 300 series cards, and was accompanied by the expected 780, 770, and 760 video cards. This was the flagship of the Kepler architecture, followed later by Maxwell architecture on GTX 900 series GPUs, and then the modern Pascal. The second card in our “revisit” series – sort of semi-re-reviews – is the GTX 780 Ti from November of 2013, which originally shipped for $700.
