Most of the loss in MT is from the loss in ST. The 4 module design should roughly equal 7 cores (assuming the MT app scales 100%). With each core of each module not being as fast as a Deneb/Thuban core, there is a shared performance drop on all the modules.

What they basicaly did is revert back to a quad core and give it a form of hardware level HT that scales better, but lost ST performance by doing so.
