Compare any two graphics cards:
Radeon HD 4850 2GB vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 4850 2GB comes with a GPU core speed of 625 MHz, and the 2048 MB of GDDR4 RAM is set to run at 993 MHz through a 256-bit bus. It also is made up of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.Compare that to the Radeon HD 6570 (OEM) 1GB, which has a core clock speed of 650 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4850 2GB should perform quite a bit faster than the Radeon HD 6570 (OEM) 1GB in general. (explain)
Texel RateThe Radeon HD 4850 2GB will be quite a bit (more or less 60%) better at texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 4850 2GB should be a lot (approximately 92%) more effective at FSAA than the Radeon HD 6570 (OEM) 1GB, and also will be able to handle higher screen 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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
