GeForce GT 130 vs Radeon HD 6950 2GB

Intro

Compare all of that to the Radeon HD 6950 2GB, which uses a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this particular model. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

GeForce GT 130		12000 MB/sec
	Difference: 148000 (1233%)

Texel Rate

The Radeon HD 6950 2GB will be a lot (more or less 487%) more effective at texture filtering than the GeForce GT 130. (explain)

Radeon HD 6950 2GB		70400 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 58400 (487%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 6950 2GB is superior to the GeForce GT 130, and very much so. (explain)

Radeon HD 6950 2GB		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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses 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 are applied per second. This figure is calculated by multiplying the total amount of 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many 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.
