Compare any two graphics cards:
GeForce 8800 Ultra vs Radeon R9 M385X
IntroThe GeForce 8800 Ultra has core clock speeds of 612 MHz on the GPU, and 1080 MHz on the 768 MB of GDDR3 RAM. It features 128 SPUs along with 64 Texture Address Units and 24 Rasterization Operator Units.Compare all that to the Radeon R9 M385X, which comes with a core clock speed of 1100 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce 8800 Ultra should perform a bit faster than the Radeon R9 M385X overall. (explain)
Texel RateThe Radeon R9 M385X should be quite a bit (approximately 57%) better at texture filtering than the GeForce 8800 Ultra. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R9 M385X is a better choice, not by a very large margin though. (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 max amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
