Compare any two graphics cards:
GeForce GTX 465 vs Radeon HD 3650
IntroThe GeForce GTX 465 has core speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 memory. It features 352 SPUs as well as 44 TAUs and 32 Rasterization Operator Units.Compare all that to the Radeon HD 3650, which makes use of a 55 nm design. AMD has set the core frequency at 725 MHz. The GDDR4 memory is set to run at a frequency of 800 MHz on this specific model. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 465 should be much faster than the Radeon HD 3650 overall. (explain)
Texel RateThe GeForce GTX 465 should be quite a bit (more or less 360%) more effective at AF than the Radeon HD 3650. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 465 is superior to the Radeon HD 3650, by far. (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 max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
