GeForce GT 240 GDDR5 vs GeForce GT 430

Intro

Compare those specs to the GeForce GT 430, which features core clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

GeForce GT 430		60 Watts
GeForce GT 240 GDDR5		70 Watts
	Difference: 10 Watts (17%)

Memory Bandwidth

In theory, the GeForce GT 240 GDDR5 should be quite a bit faster than the GeForce GT 430 overall. (explain)

GeForce GT 240 GDDR5		54400 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 25600 (89%)

Texel Rate

The GeForce GT 240 GDDR5 will be a lot (about 57%) better at texture filtering than the GeForce GT 430. (explain)

GeForce GT 240 GDDR5		17600 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 6400 (57%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 240 GDDR5 is superior to the GeForce GT 430, and very much so. (explain)

GeForce GT 240 GDDR5		4400 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 1600 (57%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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