GeForce GT 430 1GB vs GeForce GTS 150

Intro

Compare those specifications 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 features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB		60 Watts
GeForce GTS 150		141 Watts
	Difference: 81 Watts (135%)

Memory Bandwidth

The GeForce GTS 150 should in theory be a bit faster than the GeForce GT 430 1GB overall. (explain)

GeForce GTS 150		32000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 3200 (11%)

Texel Rate

The GeForce GTS 150 should be a lot (about 323%) better at texture filtering 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 high levels of AA is important to you, then the GeForce GTS 150 is the winner, by far. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
