Compare any two graphics cards:
Radeon HD 6450 (OEM) vs Radeon HD 7850
IntroThe Radeon HD 6450 (OEM) comes with clock speeds of 625 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 RAM. It features 160 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.Compare those specifications to the Radeon HD 7850, which has core clock speeds of 860 MHz on the GPU, and 1200 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7850 should be 1100% faster than the Radeon HD 6450 (OEM) in general, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 7850 is much (about 1001%) faster with regards to anisotropic filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe Radeon HD 7850 will be quite a bit (about 1001%) faster with regards to anti-aliasing than the Radeon HD 6450 (OEM), and will be able to handle higher 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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's 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 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.
