Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M230 should be 25% quicker than the GeForce 8600 GT 512MB DDR2 overall, because of its greater data rate. (explain)

Radeon R5 M230 16000 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R5 M230 is a lot (approximately 81%) better at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon R5 M230 15600 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 6960 (81%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 8600 GT 512MB DDR2 is the winner, by a large margin. (explain)

GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Radeon R5 M230 3120 Mpixels/sec
Difference: 1200 (38%)

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: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If 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 are processed in one second. This is worked out by multiplying the total amount of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels 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 amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
