GeForce GT 220 GDDR3 vs GeForce GTS 250 1GB

Intro

The GeForce GT 220 GDDR3 features core clock speeds of 625 MHz on the GPU, and 1012 MHz on the 512 MB of GDDR3 RAM. It features 48 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare those specs to the GeForce GTS 250 1GB, which features GPU clock speed of 738 MHz, and 1024 MB of GDDR3 memory set to run at 1100 MHz through a 256-bit bus. It also features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

GeForce GTS 250 1GB 70400 MB/sec
GeForce GT 220 GDDR3 32384 MB/sec
Difference: 38016 (117%)

Texel Rate

The GeForce GTS 250 1GB should be much (more or less 372%) faster with regards to anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
GeForce GT 220 GDDR3 10000 Mtexels/sec
Difference: 37232 (372%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTS 250 1GB is superior to the GeForce GT 220 GDDR3, by a large margin. (explain)

GeForce GTS 250 1GB 11808 Mpixels/sec
GeForce GT 220 GDDR3 5000 Mpixels/sec
Difference: 6808 (136%)

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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses 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 high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also 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 memory bandwidth is, the lower the ability to get to the max fill rate.
