Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 6450 (OEM)
IntroThe GeForce GT 320 has a clock speed of 540 MHz and a GDDR3 memory speed of 790 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 72 SPUs, 24 TAUs, and 8 ROPs.Compare that to the Radeon HD 6450 (OEM), which makes use of a 40 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR3 memory is set to run at a frequency of 800 MHz on this specific model. It features 160 SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 320 should be a lot faster than the Radeon HD 6450 (OEM) in general. (explain)
Texel RateThe GeForce GT 320 should be a lot (about 159%) more effective at texture filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 320 is superior to the Radeon HD 6450 (OEM), 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 largest amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can 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 Render Output Units by the clock speed of the card. 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
