Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 6770
IntroThe GeForce GTS 250 1GB features a GPU core clock speed of 738 MHz, and the 1024 MB of GDDR3 memory is set to run at 1100 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.Compare those specs to the Radeon HD 6770, which uses a 40 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 memory works at a frequency of 1050 MHz on this specific model. It features 800 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTS 250 1GB should be a little bit faster than the Radeon HD 6770 overall. (explain)
Texel RateThe GeForce GTS 250 1GB will be a lot (approximately 31%) faster with regards to anisotropic filtering than the Radeon HD 6770. (explain)
Pixel RateThe Radeon HD 6770 should be a lot (approximately 22%) more effective at full screen anti-aliasing than the GeForce GTS 250 1GB, and also should 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 data (in units of MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the 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 most 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
