Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 3650
IntroThe GeForce GT 320 comes with a core clock frequency of 540 MHz and a GDDR3 memory speed of 790 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 72 SPUs, 24 TAUs, and 8 Raster Operation Units.Compare all of that to the Radeon HD 3650, which features core speeds of 725 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR4 memory. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 3650 should in theory be just a bit better than the GeForce GT 320 overall. (explain)
Texel RateThe GeForce GT 320 should be a lot (approximately 123%) better at texture filtering than the Radeon HD 3650. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GT 320 is superior to the Radeon HD 3650, and very much so. (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 (measured in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
