It more than likely will not run faster than 2:1.
The L2 backside cache on both chips is physically on the chip die. It is the same piece of silicon and runs at the same speed as the CPU core. This is different from the backside caches we're used to, so I understand the confusion, but the later G3 and G4 chips are *different*. They put 256K or 512K of backside L2 cache on the chip right in there with the CPU and being on the same silicon and made with the same process, it runs the same speed as the CPU.
