Compare any two graphics cards:
GeForce GTX 650 Ti 2GB vs Radeon HD 4890 2GB
IntroThe GeForce GTX 650 Ti 2GB makes use of a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 RAM is set to run at a frequency of 1350 MHz on this card. It features 768 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 4890 2GB, which comes with GPU clock speed of 1000 MHz, and 2048 MB of GDDR5 RAM set to run at 975 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4890 2GB should in theory perform quite a bit faster than the GeForce GTX 650 Ti 2GB in general. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB is a lot (about 48%) faster with regards to texture filtering than the Radeon HD 4890 2GB. (explain)
Pixel RateThe Radeon HD 4890 2GB should be a small bit (approximately 8%) faster with regards to full screen anti-aliasing than the GeForce GTX 650 Ti 2GB, and will be able to handle higher screen resolutions more effectively. (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 max amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must 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 high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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 ability to reach the maximum fill rate.
