Compare any two graphics cards:
Radeon HD 4870 1GB vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 4870 1GB uses a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.Compare all that to the Radeon HD 6570 (OEM) 1GB, which comes with a core clock speed of 650 MHz and a GDDR3 memory speed of 900 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 4870 1GB should theoretically be quite a bit superior to the Radeon HD 6570 (OEM) 1GB in general. (explain)
Texel RateThe Radeon HD 4870 1GB will be quite a bit (more or less 92%) better at texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 4870 1GB is superior to the Radeon HD 6570 (OEM) 1GB, by a large margin. (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 (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must 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 AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
