GeForce GT 340 1GB vs GeForce GT 430

Intro

Compare that to the GeForce GT 430, which comes with GPU core speed of 700 MHz, and 512 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also features 96 Stream Processors, 16 Texture Address Units, and 4 ROPs.

The GeForce GT 340 1GB is a lot (about 57%) more effective at texture filtering than the GeForce GT 430. (explain)

GeForce GT 340 1GB		17600 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 6400 (57%)

Pixel Rate

The GeForce GT 340 1GB will be quite a bit (about 57%) faster with regards to FSAA than the GeForce GT 430, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GT 340 1GB		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 transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen 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 amount of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
