No.

Here is the scenario. You have one group formed with 2 branch and 6 non-branch instructions and ready to be dispatched to issue queues. The 6 non-branch instructions are all of a type that go to unified issue queues.

Now describe how grouping plays a part in deciding which UQ each of those uops are dispatched to. Contrast this with a non grouping architecture that had similar instruction mix ready to send to issue queues.

Well we established early that it maybe can't *sustain* that through the whole pipe because of branch unit execution throughput limit. But decode -> rename -> dispatch should achieve that for some cycles until the branch issue queue fills up, yes.

And that is with 6-wide rename of the replicated register files of the two unified issue queues that we are talking about.

We don't know if POWER9 can rename 6 arbitrary instructions. We don't know what dispatch restrictions it has IIRC, but it seems unlikely.

Also I suspect POWER9 effective decode throughput is at least as high as POWER8 due to removal of group limitations and reduced cracking and microcode. Possibly higher.

You have not offered any explanation. Let's get right back to the start.

How does grouping make ST mode rename easier in the context of the replicated register files / dual unified issue queues? Just outline the basic set of steps that rename is made simpler with groups, and contrast to a similar microarchitecture but without groups.

Take the example of the 6 non-branch instructions to be renamed/mapped and sent to the UQs. Consider them all 3-op integer GPR instructions of otherwise arbitary inputs and outputs.
