The core's codenamed the MCP61 and will appear as the P, S and V variants. The MCP61P supports a PCI Express x16 slot, two x1 slots, five PCU slots, four 3Gbps SATA ports, two parallel ATA drive links, Gigabit Ethernet, ten USB 2.0 ports, 7.1-channel HD audio, and digital video out.
The MCP61S and MCP61V lack digital video out, have just two SATA ports and support 10/100Mbps Ethernet. The S has PCI-E x8 for an optional external graphics card, but the V is integrated-only.
All of them will likely be made at 90nm and they will support Windows Vista. A release can be expected in August.
