Compare any two graphics cards:
Radeon HD 4850 2GB vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 4850 2GB makes use of a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR4 RAM is set to run at a frequency 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 6570 (OEM) 2GB, which makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR5 RAM 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 BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6570 (OEM) 2GB should in theory be a bit faster than the Radeon HD 4850 2GB in general. (explain)
Texel RateThe Radeon HD 4850 2GB should be a lot (approximately 60%) better at AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe Radeon HD 4850 2GB is a lot (approximately 92%) more effective at AA than the Radeon HD 6570 (OEM) 2GB, and also should be capable of handling higher resolutions more effectively. (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 past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
