Radeon HD 3650 512MB vs Radeon HD 6450 (OEM) 1GB

Intro

The Radeon HD 3650 512MB features a GPU clock speed of 725 MHz, and the 512 MB of GDDR3 memory runs at 800 MHz through a 128-bit bus. It also features 120(24x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which has a GPU core clock speed of 750 MHz, and 1024 MB of GDDR5 memory set to run at 900 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 TAUs, and 4 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 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 potential to reach the max fill rate.
