Compare any two graphics cards:
Radeon HD 3850 1GB vs Radeon HD 6670 (OEM) 1GB
IntroThe Radeon HD 3850 1GB has core speeds of 668 MHz on the GPU, and 828 MHz on the 1024 MB of GDDR3 RAM. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.
Compare that to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. ATi has clocked the core speed at 800 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this card. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 6670 (OEM) 1GB should perform much faster than the Radeon HD 3850 1GB in general. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB should be quite a bit (approximately 80%) more effective at AF than the Radeon HD 3850 1GB. (explain)
Pixel RateThe Radeon HD 3850 1GB should be a lot (about 67%) better at anti-aliasing than the Radeon HD 6670 (OEM) 1GB, and also should be able to handle higher resolutions better. (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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could 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 - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
