The test results of the Nvidia GeForce GTX 780 Ti are colored light-green in the diagrams. The color of the Radeon R9 290X and MSI Radeon R9 290X Lightning is AMD's traditional red. The two original GTX 780 Ti cards from Gainward and ASUS are turquoise. The results of the ASUS with overclocked memory are a darker shade of turquoise.

Since we already analyzed the other data in our previous reviews, we will focus on the effect from overclocking the graphics memory on the ASUS GeForce GTX 780 Ti DirectCU II OC.

3DMark (2013)

In the first 3DMark 2013 test the 1000MHz increase in memory frequency only makes the ASUS GeForce GTX 780 Ti DirectCU II OC faster by 2.2%. In the second test the performance gain is only 100 points or less than 0.3%.

Unigine Valley Bench

We’ve got the same picture in Unigine Valley:

With MSAA enabled, the 1000MHz difference in memory frequency only translates into a 2.3% difference in speed. With MSAA turned off, we can hardly see any performance benefits from our overclocking at all.

Total War: SHOGUN 2 – Fall of the Samurai

Our memory overclocking isn’t rewarding in this game, either.

The ASUS GeForce GTX 780 Ti DirectCU II OC gets a mere 1.3-2.1% faster after a 1000MHz increase in its memory frequency with antialiasing turned on. It means just a single extra frame per second, which can hardly affect the gamer’s experience.

Sniper Elite V2 Benchmark

This test shows a bigger effect from our memory overclocking:

Our memory overclocking improves the frame rate by 3.5% at 2560x1440 with antialiasing. The bottom speed is also increased in each test mode.

Sleeping Dogs

Like most other games, Sleeping Dogs doesn’t speed up much when we overclock graphics memory.
