Tench a little note about HOTRAIL Why? Because 2-way and 4-way systems are where the volumes are, at least for servers and high-end workstations. They are doing 4 way and 8 way so AMD should be fine with 4 way systems. hotrail.com "SMP Server Chip Sets HotRail's first SMP product implementation is targeted for the mainstream and high-end PC server market and is designed for the AMD-Athlon processor. HotRail has licensed the AMD-Athlon bus and is working closely with AMD to deliver the highest performance x86 SMP server solutions. Initially, HotRail will deliver reference system designs for OEM and motherboard manufacturers, for both 4- and 8-way AMD-Athlon servers. A New Generation SMP Architecture HotRail's revolutionary smart switched fabric architecture, developed for x86- and RISC-based SMP servers and workstations, eliminates the current performance bottlenecks associated with compute and data-flow intensive applications. Each CPU in a HotRail-based system is connected to either memory or I/O by a dedicated, high-speed channel via a cache-coherent switched fabric. This approach enables multiple simultaneous transactions and effectively manages CPUs as if they are in a network rather than on a traditional bus. This eliminates the diminishing returns of current shared-bus architectures. HotRail's SMP chip sets use standard high-volume components and deliver unmatched performance at an affordable price. The HotRail Channel? Essential to HotRail's SMP server chip set architecture is the HotRail Channel?, a high-speed chip-to-chip interconnect that is composed of a point-to-point signaling technology and a channel link-layer protocol. The HotRail Channel is the primary interconnect between CPUs, memory, and I/O. With multiple bi-directional connections each running full-duplex operation at 3.2GBytes/sec (for overall data throughput of up to 32GBytes/sec) and low-cycle latency, the HotRail Channel is designed to deliver very high system performance and bandwidth. Unmatched Scalability HotRail's point-to-point architecture provides unmatched scalability of memory and I/O throughput to meet ever-increasing application performance demands. Scalable to 8 CPUs and beyond, HotRail's modular architecture enables OEMs to significantly differentiate their product lines by building a broad range of CPU, memory, and I/O configurations from a single, highly scalable architecture. Modular Architecture The modular partitioning of HotRail's switched fabric architecture can be modified to work with different operating systems and CPU platforms--such as the AMD Athlon, Alpha, Pentium and MIPS--and can keep pace with future generations of CPUs while adapting to the server and workstation arena.
