GeForce GTX Titan Black vs Radeon HD 7950 3GB

Intro

Compare all that to the Radeon HD 7950 3GB, which has core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 3072 MB of GDDR5 RAM. It features 1792 SPUs as well as 112 Texture Address Units and 32 ROPs.

Radeon HD 7950 3GB		240000 MB/sec
	Difference: 96000 (40%)

Texel Rate

The GeForce GTX Titan Black should be a lot (more or less 138%) more effective at anisotropic filtering than the Radeon HD 7950 3GB. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon HD 7950 3GB		89600 Mtexels/sec
	Difference: 123760 (138%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is the winner, and very much so. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon HD 7950 3GB		25600 Mpixels/sec
	Difference: 17072 (67%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
