VS

GeForce 9500 GT DDR2 vs GeForce GT 220 GDDR3

Intro

The GeForce 9500 GT DDR2 makes use of a 65 nm design. nVidia has set the core speed at 550 MHz. The DDR2 RAM runs at a frequency of 500 MHz on this card. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare that to the GeForce GT 220 GDDR3, which uses a 40 nm design. nVidia has set the core frequency at 625 MHz. The GDDR3 RAM is set to run at a frequency of 1012 MHz on this model. It features 48 SPUs along with 16 TAUs and 8 ROPs.

GeForce 9500 GT DDR2 16000 MB/sec
Difference: 16384 (102%)

Texel Rate

The GeForce GT 220 GDDR3 is just a bit (more or less 14%) better at texture filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GT 220 GDDR3 10000 Mtexels/sec
GeForce 9500 GT DDR2 8800 Mtexels/sec
Difference: 1200 (14%)

Pixel Rate

The GeForce GT 220 GDDR3 is a little bit (more or less 14%) more effective at anti-aliasing than the GeForce 9500 GT DDR2, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GT 220 GDDR3 5000 Mpixels/sec
GeForce 9500 GT DDR2 4400 Mpixels/sec
Difference: 600 (14%)

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 (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 are processed in one second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
