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 speed at 725 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific card. It features 1440(288x5) SPUs as well as 72 TAUs and 32 Rasterization Operator Units.
Compare all that to the Radeon HD 6670 (OEM), which makes use of a 40 nm design. ATi has clocked the core speed at 800 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific card. It features 480 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 5850 should theoretically be quite a bit faster than the Radeon HD 6670 (OEM) overall. (explain)
Texel RateThe Radeon HD 5850 should be quite a bit (approximately 172%) more effective at texture filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 5850 is superior to the Radeon HD 6670 (OEM), 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 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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units of the card 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 processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
