GeForce GT 430 vs GeForce GTS 150

Intro

The GeForce GT 430 comes with a core clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 16 TAUs, and 4 ROPs.

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

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 (approximately 323%) better at 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 is much (about 323%) more effective at FSAA than the GeForce GT 430, and also capable of handling higher screen resolutions without losing too much performance. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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