GeForce GT 320 vs GeForce GT 430 (OEM)

Intro

Compare all of that to the GeForce GT 430 (OEM), which uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM works at a speed of 900 MHz on this particular model. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce GT 430 (OEM)		60 Watts
	Difference: 17 Watts (40%)

Memory Bandwidth

In theory, the GeForce GT 430 (OEM) is 14% quicker than the GeForce GT 320 overall, due to its higher data rate. (explain)

GeForce GT 430 (OEM)		28800 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 3520 (14%)

Texel Rate

The GeForce GT 320 will be just a bit (more or less 16%) better at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

GeForce GT 320		12960 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 1760 (16%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 320 is a better choice, and very much so. (explain)

GeForce GT 320		4320 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 1520 (54%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the 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 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
