Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375X is 32% faster than the GeForce GT 240 GDDR5 in general, because of its greater data rate. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 17600 (32%)

Texel Rate

The Radeon R9 M375X will be a lot (more or less 131%) faster with regards to anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 23000 (131%)

Pixel Rate

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

Radeon R9 M375X		16240 Mpixels/sec
GeForce GT 240 GDDR5		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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
