Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X should in theory be a small bit faster than the GeForce 9800 GTX overall. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 9800 GTX		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX will be a small bit (more or less 6%) more effective at AF than the Radeon R9 M375X. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 2600 (6%)

Pixel Rate

The Radeon R9 M375X will be much (more or less 50%) faster with regards to FSAA than the GeForce 9800 GTX, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 5440 (50%)

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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant 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.
