GeForce GT 240 GDDR5 1GB vs GeForce GT 320

Intro

The GeForce GT 240 GDDR5 1GB comes with a GPU core clock speed of 550 MHz, and the 1024 MB of GDDR5 memory runs at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 TAUs, and 8 ROPs.

Compare all of that to the GeForce GT 320, which features core speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 RAM. It features 72 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320 43 Watts
GeForce GT 240 GDDR5 1GB 70 Watts
Difference: 27 Watts (63%)

Memory Bandwidth

As far as performance goes, the GeForce GT 240 GDDR5 1GB should theoretically be a lot superior to the GeForce GT 320 in general. (explain)

GeForce GT 240 GDDR5 1GB 54400 MB/sec
GeForce GT 320 25280 MB/sec
Difference: 29120 (115%)

Texel Rate

The GeForce GT 240 GDDR5 1GB should be much (about 36%) better at anisotropic filtering than the GeForce GT 320. (explain)

GeForce GT 240 GDDR5 1GB 17600 Mtexels/sec
GeForce GT 320 12960 Mtexels/sec
Difference: 4640 (36%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GT 240 GDDR5 1GB is the winner, but it probably won't make a huge difference. (explain)

GeForce GT 240 GDDR5 1GB 4400 Mpixels/sec
GeForce GT 320 4320 Mpixels/sec
Difference: 80 (2%)

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 max amount of information (measured in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the 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 the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
