Memory Performance Continued

Compared to other boards we see that the RD600 chipset has a large latency problem due to the fact that both buses are independent from each other. This means the data has to navigate from one to the other at a complete different clock speed and the chipset has to negotiate all of this in a manner that causes the right data to arrive at the right time.

Linked memory buses that run with set ratios allow this to be done easier, but unlinked / asymmetric buses require the core logic to work harder. The difference between NVIDIA's nForce 680i linked and unlinked modes are only about 150MB/s, but the unlinked mode doesn't make both buses truly independent like on the ATI RD600.

Disk Performance:

The USB 2.0 tests were done using an ATA133 160GB Maxtor DiamondMax 10 hard drive (model number: 6L160PO) using HDTach's 8MB zone test enclosed in an Icy Box USB 2.0 hard drive caddy. We recorded the average read speeds in all cases.

USB 2.0 Performance is among the best of the bunch, combining virtually the fastest performance with a reasonable CPU usage.
