Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M270X should perform a bit faster than the GeForce GTS 250 512MB in general. (explain)

Radeon R9 M270X		72000 MB/sec
GeForce GTS 250 512MB		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce GTS 250 512MB should be a lot (more or less 63%) better at anisotropic filtering than the Radeon R9 M270X. (explain)

GeForce GTS 250 512MB		47232 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 18232 (63%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTS 250 512MB is superior to the Radeon R9 M270X, not by a very large margin though. (explain)

GeForce GTS 250 512MB		11808 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 208 (2%)

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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
