GeForce GT 430 (OEM) vs GeForce GTX 750

Intro

Compare those specifications to the GeForce GTX 750, which has clock speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 750 is the winner, by a large margin. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GT 430 (OEM)		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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends 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.
