Compare any two graphics cards:
GeForce GTS 150 vs Radeon HD 3650 512MB
IntroThe GeForce GTS 150 comes with a clock speed of 740 MHz and a GDDR3 memory speed of 500 MHz. It also features a 256-bit memory bus, and makes use of a 55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 3650 512MB, which uses a 55 nm design. AMD has set the core speed at 725 MHz. The GDDR3 memory runs at a frequency of 800 MHz on this model. 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 BandwidthTheoretically speaking, the GeForce GTS 150 should be a lot faster than the Radeon HD 3650 512MB in general. (explain)
Texel RateThe GeForce GTS 150 should be quite a bit (about 717%) better at AF than the Radeon HD 3650 512MB. (explain)
Pixel RateThe GeForce GTS 150 should be much (approximately 308%) more effective at full screen anti-aliasing than the Radeon HD 3650 512MB, and also should be capable of handling higher screen resolutions more effectively. (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 maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
