GeForce GT 430 vs GeForce GTX 650 Ti

Intro

Compare those specs to the GeForce GTX 650 Ti, which makes use of a 28 nm design. nVidia has set the core frequency at 928 MHz. The GDDR5 memory runs at a speed of 1350 MHz on this specific model. It features 768 SPUs as well as 64 TAUs and 16 ROPs.

GeForce GT 430		28800 MB/sec
	Difference: 57600 (200%)

Texel Rate

The GeForce GTX 650 Ti is a lot (about 430%) faster with regards to anisotropic filtering than the GeForce GT 430. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 48192 (430%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti is a better choice, by a large margin. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 12048 (430%)

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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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