Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X should be quite a bit faster than the GeForce 9800 GT 1GB in general. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M375X will be much (more or less 21%) faster with regards to anisotropic filtering than the GeForce 9800 GT 1GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 7000 (21%)

Pixel Rate

The Radeon R9 M375X is much (more or less 69%) better at AA than the GeForce 9800 GT 1GB, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 6640 (69%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip 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 Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the ability to get to the maximum fill rate.
