GeForce GT 430 (OEM) vs GeForce GTS 150

Intro

Compare all that to the GeForce GTS 150, which comes with core clock speeds of 740 MHz on the GPU, and 500 MHz on the 1024 MB of GDDR3 memory. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

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

Texel Rate

The GeForce GTS 150 is much (approximately 323%) more effective 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 high levels of AA is important to you, then the GeForce GTS 150 is a better choice, 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 data (measured in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
