GeForce 8600 GT 512MB GDDR3 vs Radeon R5 M230

Intro

The GeForce 8600 GT 512MB GDDR3 has a GPU core speed of 540 MHz, and the 512 MB of GDDR3 RAM is set to run at 700 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the Radeon R5 M230, which features a core clock speed of 780 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8600 GT 512MB GDDR3 should in theory perform much faster than the Radeon R5 M230 in general. (explain)

GeForce 8600 GT 512MB GDDR3 22400 MB/sec
Radeon R5 M230 16000 MB/sec
Difference: 6400 (40%)

Texel Rate

The Radeon R5 M230 should be much (approximately 81%) better at texture filtering 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 using a high screen resolution is important to you, then the GeForce 8600 GT 512MB GDDR3 is the winner, and very much so. (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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
