GeForce 8600 GT 1GB DDR2 vs Radeon R9 M270X

Intro

The GeForce 8600 GT 1GB DDR2 comes with a GPU clock speed of 540 MHz, and the 1024 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 ROPs.

Compare that to the Radeon R9 M270X, which has a clock speed of 725 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M270X should perform a lot faster than the GeForce 8600 GT 1GB DDR2 in general. (explain)

Radeon R9 M270X 72000 MB/sec
GeForce 8600 GT 1GB DDR2 12800 MB/sec
Difference: 59200 (463%)

Texel Rate

The Radeon R9 M270X should be much (more or less 236%) faster with regards to anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)

Radeon R9 M270X 29000 Mtexels/sec
GeForce 8600 GT 1GB DDR2 8640 Mtexels/sec
Difference: 20360 (236%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M270X is the winner, by far. (explain)

Radeon R9 M270X 11600 Mpixels/sec
GeForce 8600 GT 1GB DDR2 4320 Mpixels/sec
Difference: 7280 (169%)

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 (counted in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
