GeForce 8600 GT 256MB DDR2 vs Radeon R7 M260

Intro

The GeForce 8600 GT 256MB DDR2 comes with clock speeds of 540 MHz on the GPU, and 400 MHz on the 256 MB of DDR2 memory. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare those specifications to the Radeon R7 M260, which features a GPU core clock speed of 715 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260 is 25% faster than the GeForce 8600 GT 256MB DDR2 overall, due to its higher bandwidth. (explain)

Radeon R7 M260 16000 MB/sec
GeForce 8600 GT 256MB DDR2 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R7 M260 will be quite a bit (approximately 99%) faster with regards to anisotropic filtering than the GeForce 8600 GT 256MB DDR2. (explain)

Radeon R7 M260 17160 Mtexels/sec
GeForce 8600 GT 256MB DDR2 8640 Mtexels/sec
Difference: 8520 (99%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 M260 is the winner, and very much so. (explain)

Radeon R7 M260 5720 Mpixels/sec
GeForce 8600 GT 256MB DDR2 4320 Mpixels/sec
Difference: 1400 (32%)

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 (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
