GeForce GT 430 (OEM) vs GeForce GTS 150

Intro

Compare all of that to the GeForce GTS 150, which features a clock speed of 740 MHz and a GDDR3 memory frequency of 500 MHz. It also uses a 256-bit memory bus, and makes use of a 55 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 ROPs.

GeForce GT 430 (OEM)		60 Watts
GeForce GTS 150		141 Watts
	Difference: 81 Watts (135%)

Memory Bandwidth

Theoretically speaking, the GeForce GTS 150 will be 11% faster than the GeForce GT 430 (OEM) overall, due to its greater bandwidth. (explain)

GeForce GTS 150		32000 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 3200 (11%)

Texel Rate

The GeForce GTS 150 should be quite a bit (about 323%) better at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

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

Pixel Rate

If running with a high screen 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 (OEM)		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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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.
