Compare any two graphics cards:
GeForce GTX 965M vs Radeon R9 M265X
IntroThe GeForce GTX 965M has a GPU clock speed of 944 MHz, and the 2048 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 32 ROPs.Compare all of that to the Radeon R9 M265X, which features clock speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon R9 M265X should theoretically be just a bit superior to the GeForce GTX 965M in general. (explain)
Texel RateThe GeForce GTX 965M is much (approximately 163%) better at AF than the Radeon R9 M265X. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 965M is superior to the Radeon R9 M265X, by a large margin. (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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result 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 AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant 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 get to the maximum fill rate.
