GeForce GT 230 vs GeForce GT 440 1.5GB

Intro

The GeForce GT 230 has a core clock frequency of 550 MHz and a DDR3 memory frequency of 800 MHz. It also makes use of a 192-bit memory bus, and uses a 40 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare all that to the GeForce GT 440 1.5GB, which has a core clock frequency of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 192-bit memory bus, and makes use of a 40 nm design. It is made up of 144 SPUs, 24 TAUs, and 24 ROPs.

The GeForce GT 440 1.5GB should be much (about 62%) more effective at texture filtering than the GeForce GT 230. (explain)

GeForce GT 440 1.5GB 14256 Mtexels/sec
GeForce GT 230 8800 Mtexels/sec
Difference: 5456 (62%)

Pixel Rate

The GeForce GT 440 1.5GB should be quite a bit (more or less 224%) faster with regards to anti-aliasing than the GeForce GT 230, and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GT 440 1.5GB 14256 Mpixels/sec
GeForce GT 230 4400 Mpixels/sec
Difference: 9856 (224%)

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 information (measured in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
