GeForce 9600 GSO 384MB vs GeForce GT 220 GDDR3

Intro

Compare those specifications to the GeForce GT 220 GDDR3, which comes with core clock speeds of 625 MHz on the GPU, and 1012 MHz on the 512 MB of GDDR3 memory. It features 48 SPUs along with 16 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3		58 Watts
GeForce 9600 GSO 384MB		84 Watts
	Difference: 26 Watts (45%)

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GSO 384MB should be 19% quicker than the GeForce GT 220 GDDR3 in general, because of its greater bandwidth. (explain)

GeForce 9600 GSO 384MB		38400 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 6016 (19%)

Texel Rate

The GeForce 9600 GSO 384MB should be a lot (about 164%) better at AF than the GeForce GT 220 GDDR3. (explain)

GeForce 9600 GSO 384MB		26400 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 16400 (164%)

Pixel Rate

The GeForce 9600 GSO 384MB is quite a bit (about 32%) better at AA than the GeForce GT 220 GDDR3, and also capable of handling higher screen resolutions better. (explain)

GeForce 9600 GSO 384MB		6600 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 1600 (32%)

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 transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
