GeForce GT 430 1GB vs GeForce GTX 960

Intro

Compare all of that to the GeForce GTX 960, which has a core clock speed of 1127 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

GeForce GT 430 1GB		60 Watts
GeForce GTX 960		120 Watts
	Difference: 60 Watts (100%)

Memory Bandwidth

In theory, the GeForce GTX 960 is 289% quicker than the GeForce GT 430 1GB overall, due to its higher data rate. (explain)

GeForce GTX 960		112000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 83200 (289%)

Texel Rate

The GeForce GTX 960 should be quite a bit (about 544%) faster with regards to AF than the GeForce GT 430 1GB. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 60928 (544%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 960 is the winner, and very much so. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 33264 (1188%)

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 information (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
