Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 6670 (OEM)
IntroThe GeForce GT 340 1GB has core clock speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 6670 (OEM), which makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this particular card. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6670 (OEM) should in theory be just a bit better than the GeForce GT 340 1GB overall. (explain)
Texel RateThe Radeon HD 6670 (OEM) is a small bit (approximately 9%) better at texture filtering than the GeForce GT 340 1GB. (explain)
Pixel RateThe Radeon HD 6670 (OEM) will be much (about 45%) better at AA than the GeForce GT 340 1GB, and also should be capable of handling 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 (counted in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, 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 can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
