GeForce GT 430 1GB vs GeForce GTX 860M

Intro

Compare all of that to the GeForce GTX 860M, which features GPU clock speed of 797 MHz, and 4096 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is comprised of 1152 SPUs, 96 Texture Address Units, and 16 Raster Operation Units.

GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 65312 (583%)

Pixel Rate

The GeForce GTX 860M will be much (approximately 355%) better at FSAA than the GeForce GT 430 1GB, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 860M		12752 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 9952 (355%)

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 max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, 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 figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
