Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce GT 340 1GB makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this particular card. It features 96 SPUs as well as 32 Texture Address Units and 8 ROPs.Compare those specs to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this card. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6670 (OEM) 1GB should in theory be a little bit better than the GeForce GT 340 1GB in general. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB will be a bit (approximately 9%) more effective at anisotropic filtering than the GeForce GT 340 1GB. (explain)
Pixel RateThe Radeon HD 6670 (OEM) 1GB should be quite a bit (approximately 45%) better at anti-aliasing than the GeForce GT 340 1GB, and also will be capable of handling 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 largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
