GeForce GT 430 vs GeForce GTX Titan

Intro

Compare those specifications to the GeForce GTX Titan, which has a GPU core clock speed of 837 MHz, and 6144 MB of GDDR5 RAM set to run at 1502 MHz through a 384-bit bus. It also is made up of 2688 Stream Processors, 224 Texture Address Units, and 48 ROPs.

GeForce GT 430		11200 Mtexels/sec
	Difference: 176288 (1574%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX Titan is superior to the GeForce GT 430, by a large margin. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 37376 (1335%)

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 MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels 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 number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
