GeForce GT 220 GDDR3 vs GeForce GTX 460 SE

Intro

Compare all that to the GeForce GTX 460 SE, which comes with a core clock speed of 650 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It is comprised of 288 SPUs, 48 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3		58 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 92 Watts (159%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should perform a lot faster than the GeForce GT 220 GDDR3 in general. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 76416 (236%)

Texel Rate

The GeForce GTX 460 SE should be much (more or less 212%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 21200 (212%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 SE is a better choice, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 15800 (316%)

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 largest amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 applied 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 better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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