GeForce 8600 GT 256MB DDR2 vs Radeon R7 M260

Intro

The GeForce 8600 GT 256MB DDR2 has 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 comprised of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Compare those specs 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 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260 should be 25% quicker than the GeForce 8600 GT 256MB DDR2 overall, because of 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 is a lot (about 99%) better at AF 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 screen resolution is important to you, then the Radeon R7 M260 is superior to the GeForce 8600 GT 256MB DDR2, 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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip 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 amount of Raster Operations Pipelines by the the core 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
