In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX Titan are significantly better than the AMD Radeon HD 7870 PCS+ Vortex II Edition.

The HD 7870 has a 313 MHz higher core clock speed than the GeForce GTX Titan, but the GeForce GTX Titan has 144 more Texture Mapping Units than the HD 7870. As a result, the GeForce GTX Titan exhibits a 95.5 GTexel/s better Texture Fill Rate than the HD 7870. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7870 has a 313 MHz higher core clock speed than the GeForce GTX Titan, but the GeForce GTX Titan has 16 more Render Output Units than the HD 7870. As a result, the GeForce GTX Titan exhibits a 3.4 GPixel/s better Pixel Fill Rate than the HD 7870. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GTX Titan was released less than a year after the HD 7870, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GeForce GTX Titan has 4096 MB more video memory than the HD 7870, 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 128.4 GB/sec greater memory bandwidth than the HD 7870, which means that the memory performance of the GeForce GTX Titan is massively better than the HD 7870.

The GeForce GTX Titan has 2688 Shader Processing Units and the Radeon HD 7870 PCS+ Vortex II Edition has 1280. However, the actual shader performance of the GeForce GTX Titan is 2355 and the actual shader performance of the HD 7870 is 1251. The GeForce GTX Titan having 1104 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 HD 7870.

The GeForce GTX Titan requires 250 Watts to run but there is no entry for the Radeon HD 7870 PCS+ Vortex II Edition. We would recommend a PSU with at least 600 Watts for the GeForce GTX Titan and a PSU with at least 500 Watts for the HD 7870. The GeForce GTX Titan has been recommended a PSU with 100 Watts more than the HD 7870. The difference is significant enough that the GeForce GTX Titan may have an adverse affect on your yearly electricity bills in comparison to the HD 7870.

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.
Radeon HD 7870 PCS+ Vortex II Edition is a special edition of Radeon HD 7870.
This is one of today's most powerful editions of the reference as it features increases in both the core and memory clocks that went from 1000MHz to 1150MHz and from 1200MHz to 1250MHz.
Benchmarks indicate the performance boost is quite extreme and around 8% when compared to the reference Radeon HD 7870.
