GeForce GT 430 vs Geforce GTX 760

Intro

Compare all that to the Geforce GTX 760, which comes with a core clock speed of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1152 SPUs, 96 TAUs, and 32 ROPs.

GeForce GT 430		60 Watts
Geforce GTX 760		170 Watts
	Difference: 110 Watts (183%)

Memory Bandwidth

In theory, the Geforce GTX 760 should be 568% faster than the GeForce GT 430 in general, due to its higher bandwidth. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 163456 (568%)

Texel Rate

The Geforce GTX 760 will be a lot (approximately 740%) better at anisotropic filtering than the GeForce GT 430. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 82880 (740%)

Pixel Rate

The Geforce GTX 760 will be much (approximately 1020%) faster with regards to anti-aliasing than the GeForce GT 430, and should be able to handle higher resolutions while still performing well. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 28560 (1020%)

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 data (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per 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. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
