Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce 8800 GTS (G80) 320MB has a GPU core speed of 513 MHz, and the 320 MB of GDDR3 RAM runs at 792 MHz through a 320-bit bus. It also is comprised of 96 Stream Processors, 48 Texture Address Units, and 20 Raster Operation Units.Compare those specs to the Radeon HD 6670 (OEM) 1GB, which features GPU core speed of 800 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 480 SPUs, 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 theoretically be a little bit better than the GeForce 8800 GTS (G80) 320MB in general. (explain)
Texel RateThe GeForce 8800 GTS (G80) 320MB should be a lot (about 28%) better at texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 8800 GTS (G80) 320MB is superior to the Radeon HD 6670 (OEM) 1GB, 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 data (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better 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 most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
