VS

GeForce GT 430 vs GeForce GTS 250 1GB

Intro

The GeForce GT 430 comes with a GPU clock 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 Stream Processors, 16 Texture Address Units, and 4 Raster Operation Units.

Compare all of that to the GeForce GTS 250 1GB, which has GPU core speed of 738 MHz, and 1024 MB of GDDR3 RAM set to run at 1100 MHz through a 256-bit bus. It also features 128 SPUs, 64 Texture Address Units, and 16 ROPs.

GeForce GT 430 28800 MB/sec
Difference: 41600 (144%)

Texel Rate

The GeForce GTS 250 1GB is much (about 322%) more effective at texture filtering than the GeForce GT 430. (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
GeForce GT 430 11200 Mtexels/sec
Difference: 36032 (322%)

Pixel Rate

The GeForce GTS 250 1GB should be quite a bit (about 322%) faster with regards to AA than the GeForce GT 430, and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTS 250 1GB 11808 Mpixels/sec
GeForce GT 430 2800 Mpixels/sec
Difference: 9008 (322%)

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 max amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
