GeForce GT 430 1GB vs GeForce GTS 150

Intro

Compare that to the GeForce GTS 150, which has a GPU core clock speed of 740 MHz, and 1024 MB of GDDR3 RAM set to run at 500 MHz through a 256-bit bus. It also features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

	Difference: 3200 (11%)

Texel Rate

The GeForce GTS 150 will be quite a bit (approximately 323%) better at AF than the GeForce GT 430 1GB. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 36160 (323%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTS 150 is the winner, by a large margin. (explain)

GeForce GTS 150		11840 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 9040 (323%)

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 largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
