GeForce GT 340 vs GeForce GT 430

Intro

Compare those specifications to the GeForce GT 430, which comes with a core clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

The GeForce GT 340 is much (approximately 57%) faster with regards to AF than the GeForce GT 430. (explain)

GeForce GT 340		17600 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 6400 (57%)

Pixel Rate

The GeForce GT 340 is a lot (approximately 57%) better at FSAA than the GeForce GT 430, and capable of handling higher resolutions without losing too much performance. (explain)

GeForce GT 340		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 information (counted in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 is calculated by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
