Compare any two graphics cards:
Radeon HD 6670 (OEM) 1GB vs Radeon HD 6770 1GB
IntroThe Radeon HD 6670 (OEM) 1GB comes with a clock frequency of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.Compare all that to the Radeon HD 6770 1GB, which makes use of a 40 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 RAM works at a speed of 1050 MHz on this particular model. It features 800 SPUs along with 40 TAUs and 16 Rasterization Operator 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 in general. (explain)
Texel RateThe Radeon HD 6770 1GB should be quite a bit (more or less 88%) more effective at AF than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 6770 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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum 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!
