Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should be 67% quicker than the GeForce 9800 GT 1GB overall, due to its greater data rate. (explain)

Radeon R9 M385X 96000 MB/sec
GeForce 9800 GT 1GB 57600 MB/sec
Difference: 38400 (67%)

Texel Rate

The Radeon R9 M385X should be quite a bit (more or less 83%) faster with regards to texture filtering than the GeForce 9800 GT 1GB. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce 9800 GT 1GB 33600 Mtexels/sec
Difference: 28000 (83%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M385X is the winner, by a large margin. (explain)

Radeon R9 M385X 17600 Mpixels/sec
GeForce 9800 GT 1GB 9600 Mpixels/sec
Difference: 8000 (83%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the 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 number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
