On the C7/C710 and Pavilion 14 as shipped, where are those microcode updates stored?
This [1] should help you extract a stock coreboot.rom that you can cbfstool with. The rest is left as an exercise to the reader. (Short answer: cpu_microcode_blob.bin in CBFS)
And how exactly is a CPU different if the microcode update is patched in the factory rather than uploaded at boot? It's the same microcode in the end.
First of all, if some microcode is in the CPU from the factory rather [yada, yada, yada]
I don't care for any Stallmanian lecturing on how microcode updates work. I've worked with them, I've written code to upload them, and I've seen firsthand how their absence bricks a system. With the risk of sounding arrogant, that gives me the credit to avoid your uninformed lecturing. You have the option in coreboot to not include them. Period.
What I gather from your description is that you want is the CPU that works best without microcode updates. Ask around, or test yourself. I don't think many people have tested without microcode updates.
