Compare any two graphics cards:
GeForce GTX 965M vs Radeon R9 280
IntroThe GeForce GTX 965M uses a 28 nm design. nVidia has set the core frequency at 944 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.Compare that to the Radeon R9 280, which features a GPU core clock speed of 933 MHz, and 3072 MB of GDDR5 memory running at 1250 MHz through a 384-bit bus. It also features 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 280, in theory, should perform a lot faster than the GeForce GTX 965M overall. (explain)
Texel RateThe Radeon R9 280 should be quite a bit (approximately 73%) more effective at AF than the GeForce GTX 965M. (explain)
Pixel RateThe GeForce GTX 965M will be a small bit (approximately 1%) faster with regards to anti-aliasing than the Radeon R9 280, and will be able to handle higher screen resolutions better. (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 (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core 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 video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
