Compare any two graphics cards:
GeForce GTX 560 vs Radeon HD 4650 1GB
IntroThe GeForce GTX 560 comes with a GPU core speed of 810 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1001 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.Compare all of that to the Radeon HD 4650 1GB, which has a clock frequency of 600 MHz and a GDDR3 memory frequency of 700 MHz. It also makes use of a 128-bit bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 560 should theoretically be a lot superior to the Radeon HD 4650 1GB in general. (explain)
Texel RateThe GeForce GTX 560 will be a lot (more or less 136%) better at anisotropic filtering than the Radeon HD 4650 1GB. (explain)
Pixel RateThe GeForce GTX 560 should be quite a bit (approximately 440%) more effective at anti-aliasing than the Radeon HD 4650 1GB, and capable of handling higher screen resolutions while still performing well. (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 maximum amount of data (measured in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 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, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount 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 speed of the chip. The higher the texel rate, the better the video card will be at handling 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 the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
