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 |
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 |
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:
 |
| ASUS P5ND2-SLI |
 |
| EPoX EP-5NVA+SLI |
 |
| GIGABYTE GA-8NNXP-SLI |
 |
| MSI P4N Diamond |
All of the above use traditional switching brackets for switching between PCI-E modes.
