CRS328-24P-4S+RM inter vlan routing performance

Hi all, would someone be able provide details whether CRS328-24P-4S+RM inter vlan routing is done via switch chip/HW or CPU and what is its performance please ?
Switch itself seems to be perfect fit for my needs however I need at least 2x 1Gbit data flow (from VlanA-> VlanB and from VlanC ->VlanD) simultaneously ideally with simple accesslist allowing just some IPs. Did not find anywhere whether this box will be able cope with that.

Routing between vlans is done by CPU and it won’t be able to handle 2Gbit, only around 1Gbit:

RB450Gx4, hAP ac2, hEX, hEX S should be able to route around 2Gbit according to official test results.
