Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 6770 1GB
IntroThe GeForce GTS 450 features a clock frequency of 783 MHz and a GDDR5 memory speed of 902 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 16 ROPs.Compare that to the Radeon HD 6770 1GB, which makes use of a 40 nm design. AMD has set the core speed at 900 MHz. The GDDR5 memory is set to run 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 BandwidthTheoretically speaking, the Radeon HD 6770 1GB should be 16% quicker than the GeForce GTS 450 overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 6770 1GB should be quite a bit (more or less 44%) faster with regards to texture filtering than the GeForce GTS 450. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 6770 1GB is the winner, though not 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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
