GeForce 8600 GT 512MB GDDR3 vs Radeon R5 M230

Intro

The GeForce 8600 GT 512MB GDDR3 has a core clock speed of 540 MHz and a GDDR3 memory speed of 700 MHz. It also features a 128-bit memory bus, and uses a 80 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare all that to the Radeon R5 M230, which uses a 28 nm design. AMD has clocked the core speed at 780 MHz. The DDR3 RAM runs at a speed of 1000 MHz on this particular card. It features 320 SPUs as well as 20 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 8600 GT 512MB GDDR3 should be a lot 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 will be much (about 81%) faster with regards to anisotropic 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 resolution is important to you, then the GeForce 8600 GT 512MB GDDR3 is superior to the Radeon R5 M230, 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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
