There are literally manufacturers that had to pull gaming PC models with high end graphics cards from those markets because they couldn't meet the requirements. If you want hard numbers, manufacturers had to pull models from the market that idled at just 66w because it didn't meet the standards. In fact, the cap for idle power is, essentially, 60w for most desktop computers including gaming computers. They use a KwH/yr calculation, but it essentially amounts to if you plug 60w idle into the calculation, it gives you 60KwH/yr, which is the limit. This means the 12900K(and 12700k) test system without E-Cores and with HT turned off, still wouldn't meet the requirements. However, the 12900K system, overclocked, with E-cores still enabled actually does. The 12600 level is right on the edge, and anything lower doesn't really matter so Intel didn't care about stripping the E-cores from those.
