GeForce GT 430 vs GeForce GTX 780 Ti

Intro

Compare those specs to the GeForce GTX 780 Ti, which comes with a clock speed of 875 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 384-bit memory bus, and uses a 28 nm design. It is made up of 2880 SPUs, 240 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 190 Watts (317%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 780 Ti should in theory be much superior to the GeForce GT 430 overall. (explain)

GeForce GTX 780 Ti		336000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 307200 (1067%)

Texel Rate

The GeForce GTX 780 Ti should be much (more or less 1775%) faster with regards to anisotropic filtering than the GeForce GT 430. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 198800 (1775%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 780 Ti is a better choice, and very much so. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 39200 (1400%)

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 maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
