Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 3650
IntroThe GeForce GTS 450 1GB comes with a clock speed of 783 MHz and a GDDR5 memory speed of 902 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare all of that to the Radeon HD 3650, which uses a 55 nm design. AMD has set the core frequency at 725 MHz. The GDDR4 memory works at a speed of 800 MHz on this model. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 450 1GB should be much faster than the Radeon HD 3650 overall. (explain)
Texel RateThe GeForce GTS 450 1GB is a lot (more or less 332%) better at texture filtering than the Radeon HD 3650. (explain)
Pixel RateThe GeForce GTS 450 1GB will be quite a bit (approximately 332%) more effective at anti-aliasing than the Radeon HD 3650, and will be capable of handling higher screen 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: Bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 that 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
