GeForce GT 430 (OEM) vs Radeon HD 3650

Intro

The GeForce GT 430 (OEM) features a clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 16 TAUs, and 4 ROPs.

Compare all of that to the Radeon HD 3650, which features clock speeds of 725 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR4 RAM. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to 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 get to the max fill rate.
