GeForce GT 430 1GB vs GeForce GTS 150

Intro

The GeForce GT 430 1GB has a clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Compare all of that to the GeForce GTS 150, which has a clock frequency of 740 MHz and a GDDR3 memory frequency of 500 MHz. It also makes use of a 256-bit memory bus, and makes use of a 55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

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

Performance-wise, the GeForce GTS 150 should in theory be just a bit better 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 is quite a bit (more or less 323%) more effective 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 running with lots of anti-aliasing is important to you, then the GeForce GTS 150 is the winner, 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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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