GeForce GT 130 vs Radeon HD 6950

Intro

Compare that to the Radeon HD 6950, which makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this model. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 130		75 Watts
Radeon HD 6950		200 Watts
	Difference: 125 Watts (167%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6950 will be 1233% quicker than the GeForce GT 130 in general, due to its higher bandwidth. (explain)

Radeon HD 6950		160000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 148000 (1233%)

Texel Rate

The Radeon HD 6950 is much (more or less 487%) faster with regards to AF than the GeForce GT 130. (explain)

Radeon HD 6950		70400 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 58400 (487%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 6950 is the winner, by far. (explain)

Radeon HD 6950		25600 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 17600 (220%)

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 (measured in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can 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 Render Output Units by the clock 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
