GeForce GT 130 vs Radeon HD 6950

Intro

Compare all that to the Radeon HD 6950, which features GPU core speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1250 MHz through a 256-bit bus. It also is comprised of 1408 SPUs, 88 TAUs, and 32 ROPs.

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

Texel Rate

The Radeon HD 6950 is much (approximately 487%) better at 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 using high levels of AA is important to you, then the Radeon HD 6950 is a better choice, by a large margin. (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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
