Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 4650 512MB
IntroThe GeForce GTX 550 Ti features a clock frequency of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also features a 192-bit bus, and uses a 40 nm design. It is comprised of 192 SPUs, 32 TAUs, and 24 ROPs.Compare those specs to the Radeon HD 4650 512MB, which has a core clock frequency of 600 MHz and a DDR2 memory frequency of 500 MHz. It also features a 128-bit memory bus, and uses a 55 nm design. It features 320(64x5) SPUs, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 550 Ti should be quite a bit faster than the Radeon HD 4650 512MB overall. (explain)
Texel RateThe GeForce GTX 550 Ti should be a lot (approximately 50%) better at anisotropic filtering than the Radeon HD 4650 512MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 550 Ti 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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
