NVIDIA sheds light on its nForce4 SLI chipset

At IDF Spring 2005 Californian NVIDIA finally shed some light on its first Intel chipset.

"NVIDIA nForce4 SLI Intel edition" — this is how the new generation of SLI core logic designed for Intel processors will be called. The solution traditionally has South and North bridges:


Crush19 Northbridge:

  • Supports Pentium 4 (800/1066 MHz)
  • Dual-channel DDR2-533/667 memory controller
  • 16 PCI-E channels: 2 x PCI Express x8 or 1 x PCI Express x16
  • 800MHz HyperTransport link


MCP04 Southbridge:

  • 3 x PCI Express x1
  • 10 x USB 2.0
  • 7.1ch sound
  • Gigabit Ethernet
  • ActiveArmor hardware firewall
  • 2 x Ultra ATA-133
  • 4 x Serial ATA-II, RAID 0, 1, 0+1, 5, JBOD for two interfaces
  • 800 MHz HyperTransport link

Crush19 and MCP04 are interconnected via the 800MHz HyperTransport, which is also new for Intel-based systems. NVIDIA nForce4 SLI Intel edition will also be capable of working with dual-core Smithfield processors made using 90nm process (Pentium D 8x0).

At IDF they showcased the presale motherboard samples:
