Compare any two graphics cards:
GeForce GTS 150 vs Radeon HD 3470 512MB
IntroThe GeForce GTS 150 features a GPU clock speed of 740 MHz, and the 1024 MB of GDDR3 memory is set to run at 500 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.Compare all of that to the Radeon HD 3470 512MB, which has core speeds of 800 MHz on the GPU, and 950 MHz on the 512 MB of GDDR3 memory. It features 40(8x5) SPUs as well as 4 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce GTS 150 should be 5% quicker than the Radeon HD 3470 512MB in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTS 150 is much (about 1380%) more effective at texture filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateThe GeForce GTS 150 will be a lot (approximately 270%) better at AA than the Radeon HD 3470 512MB, and also should be able to handle higher 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 largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, 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 number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
