Compare any two graphics cards:
Radeon HD 6670 (OEM) 1GB vs Radeon HD 6770 1GB
IntroThe Radeon HD 6670 (OEM) 1GB has a core clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.Compare that to the Radeon HD 6770 1GB, which features a clock frequency of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 800 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6770 1GB should perform a little bit faster than the Radeon HD 6670 (OEM) 1GB overall. (explain)
Texel RateThe Radeon HD 6770 1GB is quite a bit (more or less 88%) faster with regards to texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6770 1GB is the winner, and very much so. (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 (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should 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, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many 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.

Thank you for showing the comparison. I thought I'd found a great deal on a Radeon 6770 1GB...until I noticed that the item listing was for a Radeon *6670*. Oh well, that's the way it goes!
