GeForce GT 430 vs GeForce GTS 150

Intro

The GeForce GT 430 has a GPU core speed of 700 MHz, and the 512 MB of GDDR3 memory runs at 900 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 16 TAUs, and 4 ROPs.

Compare all that to the GeForce GTS 150, which uses a 55 nm design. nVidia has set the core speed at 740 MHz. The GDDR3 memory works at a speed of 500 MHz on this model. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTS 150 will be 11% quicker than the GeForce GT 430 in general, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTS 150 will be quite a bit (about 323%) more effective at texture filtering than the GeForce GT 430. (explain)

GeForce GTS 150 47360 Mtexels/sec
GeForce GT 430 11200 Mtexels/sec
Difference: 36160 (323%)

Pixel Rate

The GeForce GTS 150 should be a lot (more or less 323%) better at anti-aliasing than the GeForce GT 430, and also should be able to handle higher screen resolutions better. (explain)

GeForce GTS 150 11840 Mpixels/sec
GeForce GT 430 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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
