Radeon R9 270X		179200 MB/sec
GeForce GTS 250 1GB		70400 MB/sec
	Difference: 108800 (155%)

Texel Rate

The Radeon R9 270X will be a lot (more or less 69%) faster with regards to AF than the GeForce GTS 250 1GB. (explain)

Radeon R9 270X		80000 Mtexels/sec
GeForce GTS 250 1GB		47232 Mtexels/sec
	Difference: 32768 (69%)

Pixel Rate

The Radeon R9 270X should be much (approximately 171%) better at AA than the GeForce GTS 250 1GB, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R9 270X		32000 Mpixels/sec
GeForce GTS 250 1GB		11808 Mpixels/sec
	Difference: 20192 (171%)

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 (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
