GeForce 8600 GT 512MB GDDR3 vs Radeon R5 M230

Intro

The GeForce 8600 GT 512MB GDDR3 makes use of a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 RAM runs at a frequency of 700 MHz on this specific model. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare all of that to the Radeon R5 M230, which features a GPU core clock speed of 780 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 4 Raster Operation Units.

Radeon R5 M230 16000 MB/sec
Difference: 6400 (40%)

Texel Rate

The Radeon R5 M230 should be quite a bit (about 81%) faster with regards to AF than the GeForce 8600 GT 512MB GDDR3. (explain)

Radeon R5 M230 15600 Mtexels/sec
GeForce 8600 GT 512MB GDDR3 8640 Mtexels/sec
Difference: 6960 (81%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 8600 GT 512MB GDDR3 is the winner, by far. (explain)

GeForce 8600 GT 512MB GDDR3 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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. 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 memory bandwidth is, the lower the ability to reach the max fill rate.
