Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M370X should in theory be a little bit better than the GeForce 8800 GTS (G80) 320MB in general. (explain)

Radeon R9 M370X 72000 MB/sec
GeForce 8800 GTS (G80) 320MB 63360 MB/sec
Difference: 8640 (14%)

Texel Rate

The Radeon R9 M370X should be much (about 30%) better at anisotropic filtering than the GeForce 8800 GTS (G80) 320MB. (explain)

Radeon R9 M370X 32000 Mtexels/sec
GeForce 8800 GTS (G80) 320MB 24624 Mtexels/sec
Difference: 7376 (30%)

Pixel Rate

The Radeon R9 M370X is quite a bit (more or less 25%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTS (G80) 320MB, and also able to handle higher resolutions while still performing well. (explain)

Radeon R9 M370X 12800 Mpixels/sec
GeForce 8800 GTS (G80) 320MB 10260 Mpixels/sec
Difference: 2540 (25%)

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 max amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
