I'll list three things I know:
A Phenom II can't typically be overclocked much past 4GHz without liquid cooling because the chip has a quirk where it must be chilled to extreme levels to get past that. You even require less voltage if you have liquid cooling, quite often, even if having a rather mild overclock.
If you double the ALUs on a GPU, but increase nothing else on the graphics card, including the peculiar thing of not increasing the memory bandwidth with it, you should still typically get a 20% graphics level performance increase.
Intel iGPU max speeds are typically marketing BS, typically it's limited by the thermal tolerances of the chip. You'd have to underclock the CPU portion to get that kind of real world speed. However if you did, the game performance will be typically the same, though sometimes better, because the iGPU will clock itself up higher automatically, but you'll lose CPU cycles by underclocking the CPU.
There's more, but this is what I typed.
Anyway, perhaps my statements were foggy. I'm sorry. I should have really said, "I'd like to work for a CPU or GPU company, but I still have a ways to go, including possible college. I haven't researched properly the business side of it."
