Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon HD 6770
IntroThe GeForce GT 450 (OEM) has core speeds of 790 MHz on the GPU, and 1000 MHz on the 1536 MB of GDDR5 memory. It features 144 SPUs along with 24 TAUs and 24 Rasterization Operator Units.Compare those specs to the Radeon HD 6770, which comes with clock speeds of 900 MHz on the GPU, and 1050 MHz on the 512 MB of GDDR5 memory. It features 800 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 450 (OEM), in theory, should be quite a bit faster than the Radeon HD 6770 in general. (explain)
Texel RateThe Radeon HD 6770 will be much (approximately 90%) faster with regards to anisotropic filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateThe GeForce GT 450 (OEM) is a lot (more or less 32%) better at full screen anti-aliasing than the Radeon HD 6770, 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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
