I recently ran a number of benchmarks on the GTX 780 and 780 Ti using my 4770K@4.4, and thought I'd share with you all a few observations about how these two cards compare, stock and overclocked, with a GTX 670 included for reference.
First, consider the following:
GTX 670: 1344 Stream Processors, 112 Texture Units, 32 ROPs, 256-bit Bus, 1084MHz Core Boost/6000MHz Memory Clock at stock
GTX 780: 2304 Stream Processors, 192 Texture Units, 48 ROPs, 384-bit Bus, 1006MHz Core Boost/6000MHz Memory Clock at stock
GTX 780 Ti: 2880 Stream Processors, 240 Texture Units, 48 ROPs, 384-bit Bus, 1006MHz Core Boost/7000MHz Memory Clock at stock
In terms of shaders, the 780 Ti has over twice what the 670 offers, and both the 780 and 780 Ti have at least 50% higher memory bandwidth. In theory, they should both be 40-60% faster than a 670. The 780 Ti adds an additional 17% of memory bandwidth and 25% more shader power over the 780 Ti - it should be about 20% faster than a 780.
Here are the benchmarks, with the stock boost and maximum overclocked boost attained on my sample cards:
Look at the peak power use, along with the overclocked results of the 780 - it actually outperforms a stock 780 Ti in almost every game, despite lower power use. This is despite having less memory bandwidth and lower peak shader power (the 21% overclock core overclock that I attained does not on its own compensate for the 25% shader deficit, unless not all shaders can be fully-utilized).
My view is that only in the newest non-CPU bound games, such as BF4 Single-Player (and to a certain extent Crysis 3), does the 780 Ti perform up to its potential. These are also the only two games where it comes close to doubling the performance of the GTX 670. My feeling is that in many games, it's simply too "muscle bound," held back either by its memory back-end, the game design, or the CPU platform. I believe, however, is that it will begin to pull away from the 780 as newer games are released, just as the 680 has pulled away from the 670, which it was once nearly tied with in performance.
Thoughts, impressions, projections?
