GeForce GT 220 GDDR3 vs Radeon HD 6450 (OEM)

Intro

Compare all that to the Radeon HD 6450 (OEM), which comes with core speeds of 625 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 160 SPUs along with 8 TAUs and 4 ROPs.

The GeForce GT 220 GDDR3 should be much (more or less 100%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM). (explain)

GeForce GT 220 GDDR3		10000 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 5000 (100%)

Pixel Rate

The GeForce GT 220 GDDR3 should be a lot (more or less 100%) faster with regards to AA than the Radeon HD 6450 (OEM), and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GT 220 GDDR3		5000 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 2500 (100%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
