Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 6750 1GB
IntroThe GeForce GTS 450 features a core clock frequency of 783 MHz and a GDDR5 memory speed of 902 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 192 SPUs, 32 TAUs, and 16 ROPs.Compare all that to the Radeon HD 6750 1GB, which features GPU clock speed of 725 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 720 Stream Processors, 36 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6750 1GB, in theory, should be a small bit faster than the GeForce GTS 450 overall. (explain)
Texel RateThe Radeon HD 6750 1GB is a bit (more or less 4%) more effective at texture filtering than the GeForce GTS 450. (explain)
Pixel RateThe GeForce GTS 450 will be a little bit (about 8%) more effective at full screen anti-aliasing than the Radeon HD 6750 1GB, and should be able to handle higher screen resolutions without slowing down too much. (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 information (measured in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
