Compare any two graphics cards:
GeForce GTX 460 SE vs Radeon HD 3690/3830
IntroThe GeForce GTX 460 SE makes use of a 40 nm design. nVidia has set the core speed at 650 MHz. The GDDR5 memory runs at a speed of 850 MHz on this model. It features 288 SPUs as well as 48 Texture Address Units and 32 Rasterization Operator Units.Compare all that to the Radeon HD 3690/3830, which comes with GPU core speed of 668 MHz, and 256 MB of GDDR3 RAM running at 828 MHz through a 128-bit bus. It also is comprised of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 460 SE should in theory perform much faster than the Radeon HD 3690/3830 in general. (explain)
Texel RateThe GeForce GTX 460 SE is a lot (approximately 192%) faster with regards to anisotropic filtering than the Radeon HD 3690/3830. (explain)
Pixel RateThe GeForce GTX 460 SE will be a lot (approximately 95%) better at FSAA than the Radeon HD 3690/3830, and should be able to handle 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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
