GeForce GT 240 GDDR5 vs GeForce GT 430

Intro

Compare that to the GeForce GT 430, which has a clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce GT 240 GDDR5, in theory, should perform 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 should be much (approximately 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 running with high levels of AA is important to you, then the GeForce GT 240 GDDR5 is a better choice, 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 largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
