Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 5670
IntroThe GeForce GTS 450 1GB uses a 40 nm design. nVidia has set the core speed at 783 MHz. The GDDR5 RAM works at a speed of 902 MHz on this specific model. It features 192 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 5670, which features GPU clock speed of 775 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 400(80x5) Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 5670 should in theory be a small bit superior to the GeForce GTS 450 1GB overall. (explain)
Texel RateThe GeForce GTS 450 1GB will be quite a bit (more or less 62%) faster with regards to AF than the Radeon HD 5670. (explain)
Pixel RateThe GeForce GTS 450 1GB will be quite a bit (approximately 102%) faster with regards to full screen anti-aliasing than the Radeon HD 5670, and also 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 largest amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 can be processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
