GeForce GT 430 (OEM) vs GeForce GTS 150

Intro

Compare all that to the GeForce GTS 150, which uses a 55 nm design. nVidia has clocked the core frequency at 740 MHz. The GDDR3 memory runs at a speed of 500 MHz on this specific card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTS 150 is 11% faster than the GeForce GT 430 (OEM) overall, due to its greater data rate. (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 AF 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 lots of anti-aliasing is important to you, then the GeForce GTS 150 is the winner, by far. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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