Compare any two graphics cards:
Radeon HD 4850 2GB vs Radeon HD 6670 (OEM)
IntroThe Radeon HD 4850 2GB makes use of a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR4 memory is set to run at a speed of 993 MHz on this specific card. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 6670 (OEM), which features core clock speeds of 800 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6670 (OEM) should perform a little bit faster than the Radeon HD 4850 2GB in general. (explain)
Texel RateThe Radeon HD 4850 2GB should be much (approximately 30%) more effective at texture filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe Radeon HD 4850 2GB will be much (more or less 56%) more effective at full screen anti-aliasing than the Radeon HD 6670 (OEM), and will be capable of handling higher resolutions without slowing down too much. (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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
