Compare any two graphics cards:
Radeon HD 4850 512MB vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 4850 512MB comes with a GPU core clock speed of 625 MHz, and the 512 MB of GDDR3 RAM runs at 993 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.Compare all that to the Radeon HD 6570 (OEM) 2GB, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR5 memory works at a speed of 1000 MHz on this model. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6570 (OEM) 2GB should perform a bit faster than the Radeon HD 4850 512MB in general. (explain)
Texel RateThe Radeon HD 4850 512MB is quite a bit (about 60%) more effective at texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 4850 512MB is superior to the Radeon HD 6570 (OEM) 2GB, by far. (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 transferred over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
