GeForce 8300 GS (OEM) vs GeForce GT 430

Intro

The GeForce 8300 GS (OEM) comes with a clock frequency of 450 MHz and a DDR2 memory speed of 400 MHz. It also makes use of a 64-bit bus, and uses a 80 nm design. It is made up of 8 SPUs, 4 TAUs, and 2 ROPs.

Compare those specs to the GeForce GT 430, which features GPU core speed of 700 MHz, and 512 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 16 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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