A very good article from Corsair's blog that I thought would be worth sharing

AMD Ryzen 9 7950X,  Corsair Mp700 Pro M.2, 64GB Corsair Dominator Titanium DDR5  X670E Steel Legend, MSI RTX 4090 Associate Code: H5U80QBH6BH0AXF. I am NOT an employee of EVGA

    Unscientific studies bother me; for what purpose does simplifying complicated concepts do?  It won't make people realize they don't need to exaggerate PSU wattage and continue to ignorantly treat TDP as power consumption.  About the only useful information is the chart of what voltages were needed for which frequency, gives an indication of ranges and the climb.  But most people don't apply formulas and analyze results.
     
    BTW, I'm not about to jump up and down for not even a 1GHz increase from 4GHz, it is like everyone is easily pacified and forgot that we used to see 50-60% average increases before Sandy Bridge.  Why do so many apologize for Intel?

    For Intel processors, 0.122 x TDP = Continuous Amps at 12v [source].

    I feel ya Lehpron, I wish I could get an equivalent OC on my 4930K that I did on my 930.  2.8 to 4.2and went from 1.18somehting to 1.4175 I think and was rock solid and stone cold with a good loop and was on 24/7 for a couple years.  I really do miss that kind of overhead.
     
    I don't know the internals of a CPU well enough to make an educated statement here, but I wish there was some way to keep the improvements we have seen in processors and go back to the 50%+OC's for stable desktop systems, not just Vince type people freezing them solid.
