Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon R7 M260X
IntroThe GeForce GTS 450 1GB has a clock frequency of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It features 192 SPUs, 32 TAUs, and 16 ROPs.Compare that to the Radeon R7 M260X, which features a GPU core clock speed of 825 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R7 M260X, in theory, should be just a bit faster than the GeForce GTS 450 1GB in general. (explain)
Texel RateThe GeForce GTS 450 1GB should be much (more or less 27%) faster with regards to anisotropic filtering than the Radeon R7 M260X. (explain)
Pixel RateThe GeForce GTS 450 1GB is much (about 90%) better at FSAA than the Radeon R7 M260X, and will be capable of handling 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 data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 can be processed in one second. This is calculated by multiplying the total number of texture units by the core clock 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 applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
