GeForce GT 430 1GB vs GeForce GTX 950

Intro

Compare those specs to the GeForce GTX 950, which has GPU core speed of 1024 MHz, and 2048 MB of GDDR5 memory set to run at 1652 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 48 TAUs, and 32 Raster Operation Units.

GeForce GT 430 1GB		28800 MB/sec
	Difference: 76928 (267%)

Texel Rate

The GeForce GTX 950 should be much (approximately 339%) more effective at texture filtering than the GeForce GT 430 1GB. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 37952 (339%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 950 is a better choice, and very much so. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 29968 (1070%)

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 max amount of information (counted in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
