Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GT 220 GDDR3 uses a 40 nm design. nVidia has clocked the core speed at 625 MHz. The GDDR3 RAM works at a frequency of 1012 MHz on this card. It features 48 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 6450 (OEM) 1GB, which has core clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 RAM. It features 160 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GT 220 GDDR3 should perform a bit faster than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GT 220 GDDR3 is a lot (more or less 67%) more effective at AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GT 220 GDDR3 is a better choice, and very much so. (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 data (measured in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 processed per 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 the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
