GeForce GT 230 vs GeForce GT 440 1.5GB

Intro

The GeForce GT 230 has clock speeds of 550 MHz on the GPU, and 800 MHz on the 1536 MB of DDR3 RAM. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare all of that to the GeForce GT 440 1.5GB, which uses a 40 nm design. nVidia has set the core frequency at 594 MHz. The GDDR3 memory runs at a speed of 900 MHz on this specific card. It features 144 SPUs as well as 24 TAUs and 24 ROPs.

GeForce GT 230 38400 MB/sec
Difference: 4800 (13%)

Texel Rate

The GeForce GT 440 1.5GB should be a lot (approximately 62%) more effective at anisotropic 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

If using lots of anti-aliasing is important to you, then the GeForce GT 440 1.5GB is superior to the GeForce GT 230, by a large margin. (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 data (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
