Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs Radeon HD 4890 2GB
IntroThe GeForce GTX 560 Ti 448 features a GPU core clock speed of 732 MHz, and the 1280 MB of GDDR5 RAM runs at 900 MHz through a 320-bit bus. It also is made up of 448 Stream Processors, 56 TAUs, and 40 Raster Operation Units.Compare all that to the Radeon HD 4890 2GB, which uses a 55 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM works at a speed of 975 MHz on this particular model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 560 Ti 448 should in theory be a small bit faster than the Radeon HD 4890 2GB in general. (explain)
Texel RateThe GeForce GTX 560 Ti 448 will be a small bit (approximately 2%) more effective at AF than the Radeon HD 4890 2GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 560 Ti 448 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 data (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
