Compare any two graphics cards:
Radeon HD 6450 (OEM) 1GB vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 6450 (OEM) 1GB has a GPU clock speed of 750 MHz, and the 1024 MB of GDDR5 RAM is set to run at 900 MHz through a 64-bit bus. It also is made up of 160 Stream Processors, 8 TAUs, and 4 Raster Operation Units.Compare those specifications to the Radeon HD 6570 (OEM) 1GB, which uses a 40 nm design. AMD has set the core frequency at 650 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this card. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should have identical performance. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB should be quite a bit (more or less 160%) better at anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 6570 (OEM) 1GB should be a lot (approximately 73%) better at full screen anti-aliasing than the Radeon HD 6450 (OEM) 1GB, and also will be able to handle 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 max amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one 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 - also 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
