Compare any two graphics cards:
GeForce 8600 GTS vs Radeon R7 M265
IntroThe GeForce 8600 GTS uses a 80 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR3 memory works at a frequency of 1000 MHz on this model. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the Radeon R7 M265, which features a core clock frequency of 725 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe Radeon R7 M265 will be much (about 61%) better at texture filtering than the GeForce 8600 GTS. (explain)
Pixel RateThe Radeon R7 M265 should be a small bit (approximately 7%) faster with regards to FSAA than the GeForce 8600 GTS, and also able to handle higher resolutions without losing too much performance. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
