Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 4890 1GB
IntroThe GeForce GTX 560 Ti comes with a core clock speed of 822 MHz and a GDDR5 memory frequency of 1002 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It features 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.Compare those specifications to the Radeon HD 4890 1GB, which has core clock speeds of 1000 MHz on the GPU, and 975 MHz on the 1024 MB of GDDR5 RAM. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 560 Ti should in theory be a little bit faster than the Radeon HD 4890 1GB in general. (explain)
Texel RateThe GeForce GTX 560 Ti is a lot (about 32%) better at AF than the Radeon HD 4890 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 560 Ti is the winner, by far. (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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
