Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X, in theory, should perform much faster than the GeForce 9500 GT 512MB GDDR3 in general. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 46400 (181%)

Texel Rate

The Radeon R9 M375X should be quite a bit (approximately 361%) better at anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 31800 (361%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375X is a better choice, by far. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 11840 (269%)

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 max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's 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 ANOTHER 2x. The better the 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 number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
