GeForce GT 430 vs GeForce GTX 750

Intro

Compare all that to the GeForce GTX 750, which makes use of a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this specific card. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GT 430		60 Watts
	Difference: 5 Watts (9%)

Memory Bandwidth

Theoretically, the GeForce GTX 750 should perform much faster than the GeForce GT 430 overall. (explain)

GeForce GTX 750		80000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 51200 (178%)

Texel Rate

The GeForce GTX 750 should be a lot (more or less 191%) faster with regards to AF than the GeForce GT 430. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 21440 (191%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 750 is superior to the GeForce GT 430, by far. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 13520 (483%)

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 (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core 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 maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
