AGP Fast Writes
A feature of the AGP 2.0 specification. When not using Fast Writes, the CPU sends all the video data to the system RAM and then notifies the Northbridge chip and graphics adapter that it is available for use. The graphics adapter then instructs the Northbridge chip that it is ready for this data and copies across the relevant material into the local memory. If Fast Write transactions are enabled, the CPU simply writes data directly into the local memory without caching it in the system RAM.
The advantage behind this is that if the bandwidth of the system RAM is particularly weak, then potential additional speed can be gained by not having to constantly write-read data to and from the system RAM. The disadvantage is that very tight signalling tolerances are required by all the components for fast write transactions to run successfully. At the moment, only a handful of graphics chips support the use of AGP Fast Writes and many manufacturers choose to disable the function in the video BIOS to prevent any potential problems occurring.
