GeForce GT 430 (OEM) vs Radeon HD 3650 256MB

Intro

The GeForce GT 430 (OEM) makes use of a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

Compare those specs to the Radeon HD 3650 256MB, which features a GPU core clock speed of 725 MHz, and 256 MB of DDR2 RAM set to run at 800 MHz through a 128-bit bus. It also is comprised of 120(24x5) Stream Processors, 8 TAUs, and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
