VS

GeForce 9500 GT 512MB GDDR3 vs GeForce GT 430 (OEM)

Intro

The GeForce 9500 GT 512MB GDDR3 comes with a core clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare all that to the GeForce GT 430 (OEM), which features a core clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 96 SPUs, 16 TAUs, and 4 ROPs.

Memory Bandwidth

The GeForce GT 430 (OEM) should in theory be a little bit faster than the GeForce 9500 GT 512MB GDDR3 overall. (explain)

GeForce GT 430 (OEM) 28800 MB/sec
GeForce 9500 GT 512MB GDDR3 25600 MB/sec
Difference: 3200 (13%)

Texel Rate

The GeForce GT 430 (OEM) should be quite a bit (about 27%) faster with regards to anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce GT 430 (OEM) 11200 Mtexels/sec
GeForce 9500 GT 512MB GDDR3 8800 Mtexels/sec
Difference: 2400 (27%)

Pixel Rate

The GeForce 9500 GT 512MB GDDR3 will be much (more or less 57%) faster with regards to FSAA than the GeForce GT 430 (OEM), and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 9500 GT 512MB GDDR3 4400 Mpixels/sec
GeForce GT 430 (OEM) 2800 Mpixels/sec
Difference: 1600 (57%)

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 within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
