GeForce 8600 GT 256MB DDR2 vs Radeon R5 M230

Intro

The GeForce 8600 GT 256MB DDR2 comes with a GPU core clock speed of 540 MHz, and the 256 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all of that to the Radeon R5 M230, which uses a 28 nm design. AMD has set the core speed at 780 MHz. The DDR3 memory works at a frequency of 1000 MHz on this specific card. It features 320 SPUs along with 20 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R5 M230, in theory, should perform quite a bit faster than the GeForce 8600 GT 256MB DDR2 overall. (explain)

Radeon R5 M230 16000 MB/sec
GeForce 8600 GT 256MB DDR2 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R5 M230 should be much (more or less 81%) more effective at texture filtering than the GeForce 8600 GT 256MB DDR2. (explain)

Radeon R5 M230 15600 Mtexels/sec
GeForce 8600 GT 256MB DDR2 8640 Mtexels/sec
Difference: 6960 (81%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 8600 GT 256MB DDR2 is superior to the Radeon R5 M230, and very much so. (explain)

GeForce 8600 GT 256MB 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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
