In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX Titan are significantly better than the Nvidia Tesla K20.

The GeForce GTX Titan was released less than a year after the Tesla K20, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GTX Titan has 1024 MB more video memory than the Tesla K20, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX Titan also has superior memory performance overall.

The GeForce GTX Titan has 120.4 GB/sec greater memory bandwidth than the Tesla K20, which means that the memory performance of the GeForce GTX Titan is massively better than the Tesla K20.

The GeForce GTX Titan has 2688 Shader Processing Units and the Tesla K20 has 2496. However, the actual shader performance of the GeForce GTX Titan is 2355 and the actual shader performance of the Tesla K20 is 1760. The GeForce GTX Titan having 595 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX Titan delivers a massively smoother and more efficient experience when processing graphical data than the Tesla K20.

The GeForce GTX Titan requires 250 Watts to run and the Tesla K20 requires 225 Watts. We would recommend a PSU with at least 600 Watts for the GeForce GTX Titan and a PSU with at least 650 Watts for the Tesla K20. The GeForce GTX Titan requires 25 Watts more than the Tesla K20 to run. The difference is not significant enough for the GeForce GTX Titan to have a noticeably larger impact on your yearly electricity bills than the Tesla K20.

GPU Mini Review

Mini ReviewGeForce GTX Titan (can also be addressed as GeForce GTX 685) is a high end GFX based on the 28nm Kepler architecture.
It's based on the Kepler GK110 Core used on the Tesla K20 Workstation, but with only 14 SMX activated and so it features 2688 Shader Processing Units, 48 ROPs and 224 TMUs on a 384-bit interface of fast GDDR5. The central clock runs at 837MHz and goes up to 876MHz in Turbo Mode, while the memory clock operates at 1502MHz. GeForce GTX Titan will draw no more than 250 Watts.
GeForce GTX Titan's biggest feature is the Kepler GPU Boost 2.0 which raises the GPU's central unit and Shaders speeds to a frequency even higher to the one the Turbo Boost allows, if the GPU's temperature and Voltage allows it.
Benchmarks indicate its performance is up to 30% better than GeForce GTX 680 and up to 10% worse than GeForce GTX 690. Therefore, even the most demanding games will run at the highest settings, using a 2560x1600 resolution.
Tesla K20 is a professional GPU for server and workstation purposes.
It's designed to solve the most complex high performance computing problems out there and based on the Kepler GK110, with a CUDA Count of 2496 but the drivers aren't certified for games. Therefore, even if Tesla K20 is powerful enough for even the most demanding games, it might not be compatible.
Tesla K20 is NVIDIA'S second most powerful server solution as of November 2012 and still more efficient compared to the Fermi based Professional GPUs since the Kepler's Shaders are thrice as efficient as Fermi Shaders.
