Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 6750 1GB
IntroThe GeForce GTS 450 uses a 40 nm design. nVidia has set the core frequency at 783 MHz. The GDDR5 memory runs at a speed of 902 MHz on this specific model. It features 192 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.Compare all that to the Radeon HD 6750 1GB, which makes use of a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this specific card. It features 720 SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6750 1GB should theoretically perform a little bit faster than the GeForce GTS 450 in general. (explain)
Texel RateThe Radeon HD 6750 1GB will be just a bit (about 4%) more effective at texture filtering than the GeForce GTS 450. (explain)
Pixel RateThe GeForce GTS 450 is a bit (about 8%) faster with regards to full screen anti-aliasing than the Radeon HD 6750 1GB, and should be able to handle higher resolutions better. (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 maximum amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should 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 higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock 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 fill 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 maximum fill rate.
