GeForce GT 430 (OEM) vs Geforce GTX 780

Intro

Compare those specifications to the Geforce GTX 780, which makes use of a 28 nm design. nVidia has clocked the core speed at 863 MHz. The GDDR5 memory works at a speed of 1502 MHz on this specific model. It features 2304 SPUs as well as 192 Texture Address Units and 48 Rasterization Operator Units.

	Difference: 190 Watts (317%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 780 is 901% faster than the GeForce GT 430 (OEM) in general, because of its higher bandwidth. (explain)

Geforce GTX 780		288384 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 259584 (901%)

Texel Rate

The Geforce GTX 780 will be quite a bit (about 1379%) better at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 154496 (1379%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 780 is the winner, and very much so. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 38624 (1379%)

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 megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
