GeForce GT 430 vs GeForce GTS 150

Intro

The GeForce GT 430 comes with core clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

Compare those specifications to the GeForce GTS 150, which comes with GPU clock speed of 740 MHz, and 1024 MB of GDDR3 RAM running at 500 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 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

The GeForce GTS 150, in theory, should be just a bit faster than the GeForce GT 430 in general. (explain)

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

Texel Rate

The GeForce GTS 150 is a lot (about 323%) faster with regards to anisotropic 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 quite a bit (more or less 323%) more effective at anti-aliasing than the GeForce GT 430, and will be able to handle higher resolutions without slowing down too much. (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 maximum amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 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 can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a 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. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends 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.
