Compare any two graphics cards:
GeForce GTX 465 vs Radeon R9 M380
IntroThe GeForce GTX 465 has core clock speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 memory. It features 352 SPUs along with 44 Texture Address Units and 32 Rasterization Operator Units.Compare all that to the Radeon R9 M380, which features GPU core speed of 1000 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce GTX 465, in theory, should be a bit faster than the Radeon R9 M380 in general. (explain)
Texel RateThe Radeon R9 M380 will be quite a bit (more or less 50%) better at anisotropic filtering than the GeForce GTX 465. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 465 is a better choice, by a large margin. (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 max amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, 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 maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
