Compare any two graphics cards:
GeForce GTX 960 vs Radeon HD 4830 512MB
IntroThe GeForce GTX 960 has a GPU core clock speed of 1127 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1750 MHz through a 128-bit bus. It also features 1024 Stream Processors, 64 TAUs, and 32 ROPs.Compare that to the Radeon HD 4830 512MB, which features a core clock speed of 575 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and uses a 55 nm design. It is made up of 640(128x5) SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 960, in theory, should perform quite a bit faster than the Radeon HD 4830 512MB in general. (explain)
Texel RateThe GeForce GTX 960 will be quite a bit (approximately 292%) faster with regards to texture filtering than the Radeon HD 4830 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 960 is superior to the Radeon HD 4830 512MB, 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 maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, 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 AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
