  They should use pbo it's fair to

  Is you using pbo some people are t using pbo which I think isn't fair because that i9 is oc to snot

  It's not just the gaming world -- it's the entire world except for long-running CPU intensive tasks. Handbrake and blender are valuable benchmarking tools for seeing what a CPU is capable of when pushed to the limit, but the vast majority of users -- even most power users -- don't do that.
  
  Sure, Intel has more work to do to improve power efficiency in long running CPU intensive workloads, but taking the worst case power usage scenarios distorts the picture as much as you're claiming the reviewers are doing.

  Can't calculate efficiency without scores. Also, well known that power scales much faster than performance. The proper way to compare efficiency is really at constant work rate or constant power.

  Sorry sir I can't. You haven't provided me the data for how much time each test took! Would you be so kind as to do that?

  Sorry, this is a direct link to Tom's bench:
  https://cdn.mos.cms.futurecdn.net/if3Lox9ZJBRxjbhr...
  this is for "blender bmw27" in which both 12900k and 5950x finish the job around 80 seconds BUT 12900k sucks power for about 70 percent more than 5950x.
  
  you can find other benches here:

  I'm wondering why Ian hasn't put 12900k nominal TDP in results just like all other CPU's! When 10900k was released with nominal TDP of 125, Ian put than number in every bench while in reality 10900k was consuming up to 254 (according to the Ian's review)! When I asked him to put real numbers of power consumption for every test he said I can't because of time and because I've too much to do and because I've no money to pay and delegate such works to an assistant!
  But now we have 12900k with nominal TDP of 241 which seems unpleasant to Ian to put it in front of it in results.

  Last gen game. How about glquake?
  
  1 billion computing devices and just a few million game units sold? What does it mean? Gamers are a tiny but vocal minority.
  If they bring this performance at 5W on low and 45W on high then its good for majority of people. This is just a space heater.

  so throwing more cores on a game that can´t make use of them is usless thanks for clarifing that.... genius!!
  
  when a 5600x is producing 144 FPS and a 5950x is producing 150 FPS the 5600x is the clear winner when it comes to efficency.
  
  now try to cool the 12900K in a work environment with an air cooler.
  i can cool my threadripper with a noctua aircooler and let it run under full load for ours.
  
  i am really curious to see how the 12900k will handle that.
  
  i am not an amd fanboy. i was using anti-consumer intel for a decade before switching to ryzen.
  i would us intel again when it makes sense for me (i need my pc for work not gaming).
  
  but with this power draw it does not make sense.

  The 12900k is fine with a Noctua D15 in a work environment. Doesn't matter if you're hammering it at 95C the whole time, the D15 doesn't get louder. But it's no megachip like a Threadripper. For that on the Intel side you'd wait for Sapphire Rapids or put up with an existing Xeon Gold with 8-32 Ice Lake cores at 10nm.

  How would it be justified to buy Xeon Gold in place of Threadripper and Epyc?!
