GeForce GT 430 vs GeForce GTX 860M

Intro

The GeForce GT 430 makes use of a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Compare all of that to the GeForce GTX 860M, which features core speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1152 SPUs along with 96 TAUs and 16 ROPs.

GeForce GTX 860M 76512 Mtexels/sec
GeForce GT 430 11200 Mtexels/sec
Difference: 65312 (583%)

Pixel Rate

The GeForce GTX 860M should be much (about 355%) faster with regards to anti-aliasing than the GeForce GT 430, and will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 860M 12752 Mpixels/sec
GeForce GT 430 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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
