Compare any two graphics cards:
Radeon HD 6670 (OEM) 1GB vs Radeon HD 6770 1GB
IntroThe Radeon HD 6670 (OEM) 1GB uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this model. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.Compare all that to the Radeon HD 6770 1GB, which features a core clock speed of 900 MHz and a GDDR5 memory speed of 1050 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 800 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6770 1GB should theoretically perform a bit faster than the Radeon HD 6670 (OEM) 1GB in general. (explain)
Texel RateThe Radeon HD 6770 1GB should be quite a bit (approximately 88%) better at anisotropic filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 6770 1GB will be quite a bit (approximately 125%) more effective at FSAA than the Radeon HD 6670 (OEM) 1GB, and also capable of handling higher screen 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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach 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!
