GeForce GT 220 GDDR3 vs GeForce GTX 460 SE

Intro

Compare that to the GeForce GTX 460 SE, which features core speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 288 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.

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

Performance-wise, the GeForce GTX 460 SE should in theory be much superior to the GeForce GT 220 GDDR3 overall. (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 is quite a bit (more or less 212%) better at texture 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

The GeForce GTX 460 SE is a lot (approximately 316%) better at FSAA than the GeForce GT 220 GDDR3, and also should be able to handle higher screen resolutions without losing too much performance. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, 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 number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
