Compare any two graphics cards:
Radeon HD 3850 512MB vs Radeon HD 6450 (OEM) 1GB
IntroThe Radeon HD 3850 512MB has core speeds of 668 MHz on the GPU, and 828 MHz on the 512 MB of GDDR3 memory. It features 320(64x5) SPUs along with 16 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which uses a 40 nm design. AMD has set the core speed at 750 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this particular model. It features 160 SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 3850 512MB should perform quite a bit faster than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe Radeon HD 3850 512MB will be quite a bit (more or less 78%) more effective at AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 3850 512MB will be much (about 256%) better at AA than the Radeon HD 6450 (OEM) 1GB, and also should be capable of handling 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 information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, 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 most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
