GeForce GTX 465 vs Radeon HD 6950

Intro

Compare all of that to the Radeon HD 6950, which has core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon HD 6950 should perform quite a bit faster than the GeForce GTX 465 in general. (explain)

Radeon HD 6950		160000 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 57408 (56%)

Texel Rate

The Radeon HD 6950 should be a lot (more or less 164%) faster with regards to texture filtering than the GeForce GTX 465. (explain)

Radeon HD 6950		70400 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 43692 (164%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 6950 is a better choice, by far. (explain)

Radeon HD 6950		25600 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 6176 (32%)

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 largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, 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 write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
