Compare any two graphics cards:
GeForce GTX 950 vs Radeon HD 4830 1GB
IntroThe GeForce GTX 950 features a core clock frequency of 1024 MHz and a GDDR5 memory frequency of 1652 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 768 SPUs, 48 Texture Address Units, and 32 ROPs.Compare those specs to the Radeon HD 4830 1GB, which features a GPU core clock speed of 575 MHz, and 1024 MB of GDDR4 memory running at 900 MHz through a 256-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 950 should in theory perform quite a bit faster than the Radeon HD 4830 1GB overall. (explain)
Texel RateThe GeForce GTX 950 is much (more or less 167%) more effective at AF than the Radeon HD 4830 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 950 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 max amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 applied in one second. This number is calculated by multiplying the total amount 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 amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's 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 rate also depends 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.
