PCI-express - is there a typo in the Intel 5500 overview
- by Martin
The overview for the 5500 and 5520 chipsets state that there is a total bandwidth of up to 48GB/s on each PCI Express x8 interface.
http://www.intel.com/products/server/chipsets/5500-5520/5500-5520-overview.htm
My understanding (admittedly from wikipedia) is that PCI-e Gen 2 runs at 500MB/s per lane. The 5520 has 36 lanes, and so would be limited to a total of 18GB/s.
Am I missing something here, or is Intel's claimed 48GB/s a typo that should say 18GB/s ?
