GeForce GT 430 (OEM) vs GeForce GTS 150

Intro

Compare all that to the GeForce GTS 150, which has GPU clock speed of 740 MHz, and 1024 MB of GDDR3 RAM set to run at 500 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 TAUs, 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

The GeForce GTS 150 should in theory perform just a bit faster than the GeForce GT 430 (OEM) overall. (explain)

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

Texel Rate

The GeForce GTS 150 is quite a bit (approximately 323%) more effective 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 high levels of AA is important to you, then the GeForce GTS 150 is a better choice, 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 transferred over the external memory interface within a second. The number is worked out by multiplying the 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 ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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