Geforce GTX 760 vs Radeon HD 6950 2GB

Intro

Compare all of that to the Radeon HD 6950 2GB, which comes with clock speeds of 800 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 memory. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

Geforce GTX 760		170 Watts
Radeon HD 6950 2GB		200 Watts
	Difference: 30 Watts (18%)

Memory Bandwidth

Performance-wise, the Geforce GTX 760 should in theory be just a bit superior to the Radeon HD 6950 2GB overall. (explain)

Geforce GTX 760		192256 MB/sec
Radeon HD 6950 2GB		160000 MB/sec
	Difference: 32256 (20%)

Texel Rate

The Geforce GTX 760 should be quite a bit (about 34%) faster with regards to texture filtering than the Radeon HD 6950 2GB. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon HD 6950 2GB		70400 Mtexels/sec
	Difference: 23680 (34%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 760 is a better choice, by a large margin. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon HD 6950 2GB		25600 Mpixels/sec
	Difference: 5760 (23%)

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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's 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 higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
