Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce GT 340 1GB features clock speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific card. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6670 (OEM) 1GB should be a little bit faster than the GeForce GT 340 1GB overall. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB should be a small bit (more or less 9%) more effective at AF than the GeForce GT 340 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6670 (OEM) 1GB is a better choice, by a large margin. (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 transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should 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, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 potential to get to the maximum fill rate.
