VS

GeForce GT 430 (OEM) vs Radeon HD 3650 512MB

Intro

The GeForce GT 430 (OEM) has a GPU clock speed of 700 MHz, and the 2048 MB of GDDR3 RAM runs at 900 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 16 TAUs, and 4 Raster Operation Units.

Compare all that to the Radeon HD 3650 512MB, which uses a 55 nm design. AMD has set the core frequency at 725 MHz. The GDDR3 RAM works at a speed of 800 MHz on this particular card. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum 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 clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
