Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon R9 M395X
IntroThe GeForce GTS 250 1GB features a core clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also features a 256-bit memory bus, and uses a 65/55 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare that to the Radeon R9 M395X, which comes with clock speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 M395X should be 127% faster than the GeForce GTS 250 1GB overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon R9 M395X is quite a bit (about 96%) faster with regards to texture filtering than the GeForce GTS 250 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R9 M395X is the winner, and very much so. (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 moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video 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 maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
