Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 6450 (OEM)
IntroThe GeForce GT 220 GDDR3 comes with a clock speed of 625 MHz and a GDDR3 memory speed of 1012 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is made up of 48 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specs to the Radeon HD 6450 (OEM), which has GPU clock speed of 625 MHz, and 512 MB of GDDR3 memory running at 800 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 220 GDDR3 will be 153% faster than the Radeon HD 6450 (OEM) in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GT 220 GDDR3 will be quite a bit (about 100%) more effective at AF than the Radeon HD 6450 (OEM). (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 220 GDDR3 is a better choice, by a large margin. (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 data (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
