Compare any two graphics cards:
Radeon HD 5870 vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 5870 uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory runs at a frequency of 1200 MHz on this particular model. It features 1600(320x5) SPUs as well as 80 TAUs and 32 ROPs.Compare those specs to the Radeon HD 6570 (OEM) 1GB, which comes with clock speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5870 should be much faster than the Radeon HD 6570 (OEM) 1GB overall. (explain)
Texel RateThe Radeon HD 5870 should be much (more or less 336%) better at anisotropic filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 5870 will be much (more or less 423%) more effective at AA than the Radeon HD 6570 (OEM) 1GB, and capable of handling higher screen resolutions without losing too much performance. (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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core 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 rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
