Compare any two graphics cards:
GeForce GT 340 vs Radeon HD 5450
IntroThe GeForce GT 340 makes use of a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 memory runs at a speed of 850 MHz on this model. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 5450, which has a core clock frequency of 650 MHz and a DDR3 memory speed of 800 MHz. It also uses a 64-bit memory bus, and makes use of a 40 nm design. It is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 340 should theoretically perform quite a bit faster than the Radeon HD 5450 overall. (explain)
Texel RateThe GeForce GT 340 will be quite a bit (approximately 238%) more effective at texture filtering than the Radeon HD 5450. (explain)
Pixel RateThe GeForce GT 340 is quite a bit (about 69%) more effective at FSAA than the Radeon HD 5450, and able to handle higher screen resolutions while still performing well. (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 max amount of information (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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 calculated by multiplying the amount of Render Output Units by the the core clock speed. 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
