GeForce GT 430 (OEM) vs GeForce GTX 950

Intro

Compare all that to the GeForce GTX 950, which features GPU core speed of 1024 MHz, and 2048 MB of GDDR5 RAM set to run at 1652 MHz through a 128-bit bus. It also features 768 Stream Processors, 48 Texture Address Units, and 32 ROPs.

GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 37952 (339%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 950 is superior to the GeForce GT 430 (OEM), by a large margin. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GT 430 (OEM)		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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
