GeForce GT 220 GDDR3 vs GeForce GTX 590

Intro

Compare those specs to the GeForce GTX 590, which uses a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 memory is set to run at a speed of 855 MHz on this specific card. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3		58 Watts
GeForce GTX 590		365 Watts
	Difference: 307 Watts (529%)

Memory Bandwidth

In theory, the GeForce GTX 590 should perform much faster than the GeForce GT 220 GDDR3 in general. (explain)

GeForce GTX 590		328320 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 295936 (914%)

Texel Rate

The GeForce GTX 590 should be a lot (approximately 677%) more effective at AF than the GeForce GT 220 GDDR3. (explain)

GeForce GTX 590		77696 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 67696 (677%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 590 is a better choice, by far. (explain)

GeForce GTX 590		58272 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 53272 (1065%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the 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 amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
