Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X should theoretically perform a little bit faster than the GeForce 9800 GTX in general. (explain)

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

Texel Rate

The GeForce 9800 GTX should be just a bit (more or less 6%) faster with regards to AF than the Radeon R9 M375X. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M375X is superior to the GeForce 9800 GTX, by far. (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 largest amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling 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 the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
