Compare any two graphics cards:
GeForce GTX 650 vs Radeon R9 M385X
IntroThe GeForce GTX 650 comes with a GPU core speed of 1058 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1250 MHz through a 128-bit bus. It also features 384 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.Compare all that to the Radeon R9 M385X, which uses a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this model. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon R9 M385X should theoretically be a little bit better than the GeForce GTX 650 overall. (explain)
Texel RateThe Radeon R9 M385X is quite a bit (more or less 82%) more effective at AF than the GeForce GTX 650. (explain)
Pixel RateThe Radeon R9 M385X should be just a bit (more or less 4%) faster with regards to anti-aliasing than the GeForce GTX 650, and also capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, 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 texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling 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 the video card can possibly record to the local memory in one 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 filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
