GeForce GT 430 vs GeForce GTX 980

Intro

Compare that to the GeForce GTX 980, which has core clock speeds of 1126 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

GeForce GT 430		60 Watts
GeForce GTX 980		165 Watts
	Difference: 105 Watts (175%)

Memory Bandwidth

In theory, the GeForce GTX 980 should perform a lot faster than the GeForce GT 430 in general. (explain)

GeForce GTX 980		224000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 195200 (678%)

Texel Rate

The GeForce GTX 980 should be quite a bit (about 1187%) faster with regards to AF than the GeForce GT 430. (explain)

GeForce GTX 980		144128 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 132928 (1187%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 980 is superior to the GeForce GT 430, by far. (explain)

GeForce GTX 980		72064 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 69264 (2474%)

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 largest amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
