Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce GT 340 1GB comes with a GPU core speed of 550 MHz, and the 1024 MB of GDDR5 memory is set to run at 850 MHz through a 128-bit bus. It also features 96 SPUs, 32 Texture Address Units, and 8 ROPs.Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which features a clock speed of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6670 (OEM) 1GB, in theory, should be a small bit faster than the GeForce GT 340 1GB in general. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB is a bit (approximately 9%) faster with regards to anisotropic filtering than the GeForce GT 340 1GB. (explain)
Pixel RateThe Radeon HD 6670 (OEM) 1GB should be a lot (approximately 45%) better at AA than the GeForce GT 340 1GB, and will 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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one 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 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
