Compare any two graphics cards:
GeForce GTX 460 2GB vs Radeon R9 M385X
IntroThe GeForce GTX 460 2GB comes with a GPU core speed of 675 MHz, and the 2048 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.Compare those specifications to the Radeon R9 M385X, which has GPU core speed of 1100 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the GeForce GTX 460 2GB should theoretically be a small bit superior to the Radeon R9 M385X overall. (explain)
Texel RateThe Radeon R9 M385X should be a lot (more or less 63%) more effective at anisotropic filtering than the GeForce GTX 460 2GB. (explain)
Pixel RateThe GeForce GTX 460 2GB will be quite a bit (more or less 23%) faster with regards to FSAA than the Radeon R9 M385X, and able to handle higher screen resolutions without slowing down too much. (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 information (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core 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 in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
