ULi has just released a low-cost single-chip solution for AMD Athlon 64. With HD Audio, SATA2 RAID, and Dual x8 PCIe.
The M1697 is ULi's answer to "What would you do to improve nForce4?" nForce4 is the other single chip AMD chipset, and the ULi M1697 can be considered very similar to NVIDIA nForce4-SLI - with the significant addition of 7.1 High Definition (HD Azalia) audio. The advantage of a single-chip chipset is there is no need to worry about the communication speed of the North Bridge to South Bridge. ULi also communicates with the AMD processor (64 or 64x2) by means of the 16 x 16 HyperTransport bus, which delivers continuous throughput of up to 8GB/sec. This ensures that the processor/ chipset link provides sufficient speed so that it does not become a bottleneck in system performance.
