Radeon R7 250X 2GB		72000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 43200 (150%)

Texel Rate

The Radeon R7 250X 2GB should be a lot (about 257%) faster with regards to AF than the GeForce GT 430 1GB. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 28800 (257%)

Pixel Rate

The Radeon R7 250X 2GB will be a lot (more or less 471%) faster with regards to AA than the GeForce GT 430 1GB, and should be able to handle higher resolutions while still performing well. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 13200 (471%)

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 maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a 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 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number 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 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 chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
