Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 5670
IntroThe GeForce GT 340 1GB makes use of a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 memory works at a speed of 850 MHz on this particular model. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 5670, which comes with a GPU core clock speed of 775 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also features 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 5670 should theoretically be a small bit superior to the GeForce GT 340 1GB overall. (explain)
Texel RateThe GeForce GT 340 1GB will be a little bit (approximately 14%) better at AF than the Radeon HD 5670. (explain)
Pixel RateThe Radeon HD 5670 should be quite a bit (approximately 41%) more effective at AA than the GeForce GT 340 1GB, and also will be capable of handling 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 largest amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
