That graph is for the more powerful 655.

The XSPC Pump is actually a bit stronger than the 655-B:
MCP655 + EK Top: 4.95 PSI
MCP655 Stock: 4.72 PSI
XSPC 750: 3.59 PSI
655-B + EK Top: 3.38 PSI
655-B Stock: 3.23 PSI
At extremely high flow rates the 655-B performs better than the XSPC 750 but those conditions do not represent a real loop.
The 655-B also uses almost double the amount of electrical power. It's only advantage is that it's dead silent.
