GeForce GT 220 GDDR3 vs GeForce GTX 465

Intro

Compare that to the GeForce GTX 465, which features clock speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 RAM. It features 352 SPUs along with 44 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 70208 (217%)

Texel Rate

The GeForce GTX 465 will be quite a bit (about 167%) more effective at texture filtering than the GeForce GT 220 GDDR3. (explain)

GeForce GTX 465		26708 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 16708 (167%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 465 is superior to the GeForce GT 220 GDDR3, by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 14424 (288%)

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 max amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
