Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 5750 512MB
IntroThe GeForce GTS 450 1GB comes with core speeds of 783 MHz on the GPU, and 902 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs as well as 32 Texture Address Units and 16 ROPs.Compare that to the Radeon HD 5750 512MB, which features a core clock speed of 700 MHz and a GDDR5 memory speed of 1150 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 5750 512MB should perform a lot faster than the GeForce GTS 450 1GB overall. (explain)
Texel RateThe Radeon HD 5750 512MB will be a bit (about 1%) faster with regards to anisotropic filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateThe GeForce GTS 450 1GB will be a bit (approximately 12%) more effective at AA than the Radeon HD 5750 512MB, and also should be able to handle higher resolutions without losing too much performance. (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 maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
