GeForce GT 220 GDDR3 vs GeForce GT 420

Intro

The GeForce GT 220 GDDR3 uses a 40 nm design. nVidia has clocked the core frequency at 625 MHz. The GDDR3 memory works at a speed of 1012 MHz on this card. It features 48 SPUs as well as 16 Texture Address Units and 8 ROPs.

Compare those specs to the GeForce GT 420, which has a GPU core clock speed of 700 MHz, and 2048 MB of GDDR3 RAM running at 900 MHz through a 128-bit bus. It also is made up of 48 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

GeForce GT 420 50 Watts
GeForce GT 220 GDDR3 58 Watts
Difference: 8 Watts (16%)

Memory Bandwidth

In theory, the GeForce GT 220 GDDR3 will be 12% faster than the GeForce GT 420 overall, due to its greater data rate. (explain)

GeForce GT 220 GDDR3 32384 MB/sec
GeForce GT 420 28800 MB/sec
Difference: 3584 (12%)

Texel Rate

The GeForce GT 220 GDDR3 is quite a bit (more or less 79%) better at AF than the GeForce GT 420. (explain)

GeForce GT 220 GDDR3 10000 Mtexels/sec
GeForce GT 420 5600 Mtexels/sec
Difference: 4400 (79%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GT 220 GDDR3 is superior to the GeForce GT 420, by far. (explain)

GeForce GT 220 GDDR3 5000 Mpixels/sec
GeForce GT 420 2800 Mpixels/sec
Difference: 2200 (79%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
