GeForce GT 430 vs Geforce GTX 670

Intro

Compare that to the Geforce GTX 670, which has a clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 32 ROPs.

GeForce GT 430		11200 Mtexels/sec
	Difference: 91280 (815%)

Pixel Rate

The Geforce GTX 670 is a lot (more or less 946%) better at FSAA than the GeForce GT 430, and able to handle higher screen resolutions better. (explain)

Geforce GTX 670		29280 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 26480 (946%)

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 data (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
