Intel X99 Express Chipset
Although LGA2011-V3 sockets are physically identical to the older LGA2011 sockets, they’re electrically different, and your Sandy Bridge Extreme or Ivy Bridge Extreme CPUs will not work (actually I’m not sure what would happen if you tried. If you do try, please let me know.) The new socket architecture is supported by Intel’s new X99 Express chipset. For comparison, here’s the architecture diagram of the X79 chipset:
…and here’s the diagram for the X99 Express chipset:
Looking at these diagrams, you can see that the major differences are:
- 40 PCI-E Gen 3 lanes from the CPU vs. 40 PCI-E Gen 2 lanes
- 2133MHz DDR4 memory instead of DDR3 memory
- Native USB 3.0 support. Finally.
- Increased communications speed between the chipset and its USB ports and PCI-E 2.0 lanes
- More SATA ports: 10 vs. 6
So, what can we expect from this new platform?
