Compare any two graphics cards:
Radeon HD 5850 vs Radeon HD 6670 (OEM)
IntroThe Radeon HD 5850 uses a 40 nm design. ATi has set the core frequency at 725 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this card. It features 1440(288x5) SPUs as well as 72 Texture Address Units and 32 ROPs.
Compare those specifications to the Radeon HD 6670 (OEM), which comes with a GPU core clock speed of 800 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 480 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon HD 5850 should theoretically be a lot better than the Radeon HD 6670 (OEM) overall. (explain)
Texel RateThe Radeon HD 5850 should be much (approximately 172%) more effective at AF than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe Radeon HD 5850 will be much (more or less 263%) more effective at anti-aliasing than the Radeon HD 6670 (OEM), and also 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 maximum amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 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 reach the max fill rate.
