Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 is 38% faster than the GeForce 9500 GT 512MB GDDR3 overall, because of its greater bandwidth. (explain)

Radeon R9 M375		35200 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 9600 (38%)

Texel Rate

The Radeon R9 M375 should be much (approximately 361%) better at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 31800 (361%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M375 is superior to the GeForce 9500 GT 512MB GDDR3, and very much so. (explain)

Radeon R9 M375		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 maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its 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 clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
