Compare any two graphics cards:
GeForce GTS 150 vs Radeon HD 3650 256MB
IntroThe GeForce GTS 150 comes with a clock frequency of 740 MHz and a GDDR3 memory frequency of 500 MHz. It also features a 256-bit memory bus, and uses a 55 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare all of that to the Radeon HD 3650 256MB, which makes use of a 55 nm design. AMD has clocked the core speed at 725 MHz. The DDR2 memory runs at a frequency of 800 MHz on this card. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 150 is 25% quicker than the Radeon HD 3650 256MB overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTS 150 will be quite a bit (more or less 717%) more effective at AF than the Radeon HD 3650 256MB. (explain)
Pixel RateThe GeForce GTS 150 should be much (more or less 308%) more effective at AA than the Radeon HD 3650 256MB, and able to handle higher screen resolutions without losing too much performance. (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 megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
