Compare any two graphics cards:
Radeon HD 6450 (OEM) vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 6450 (OEM) uses a 40 nm design. AMD has set the core speed at 625 MHz. The GDDR3 RAM works at a frequency of 800 MHz on this particular card. It features 160 SPUs along with 8 Texture Address Units and 4 ROPs.Compare those specs to the Radeon HD 6570 (OEM) 1GB, which features GPU clock speed of 650 MHz, and 1024 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6570 (OEM) 1GB, in theory, should be much faster than the Radeon HD 6450 (OEM) in general. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB should be quite a bit (more or less 212%) faster with regards to texture filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe Radeon HD 6570 (OEM) 1GB should be much (more or less 108%) faster with regards to full screen anti-aliasing than the Radeon HD 6450 (OEM), and also will be capable of handling higher screen resolutions without slowing down too much. (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 max amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 video card 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 amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
