GeForce GT 430 1GB vs GeForce GTS 150

Intro

Compare all of that to the GeForce GTS 150, which has 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 ROPs.

Memory Bandwidth

In theory, the GeForce GTS 150 should perform a bit faster than the GeForce GT 430 1GB in general. (explain)

GeForce GTS 150		32000 MB/sec
GeForce GT 430 1GB		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 1GB. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GT 430 1GB		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 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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
