A lot of crap detect here boys to justify intel hot potato..
Intel isn't the one forcing the max turbo on all 8 cores. If you read the article he confirmed Asus sets the 9900k default to use the TDP limit while all the other manufacturers have it disabled. Second the 9900k uses less power and runs cooler than the 2700x at the same clock speed as a 2700x. So if a 2700x could reach 4.7Ghz it would use more power and run hotter than a 9900k.

It should be an option by the motherboard manufacturer. Just like how many video cards have a bios switch to use a low power profile or a high performance profile.

Quote from Linus' review

Quote:
Since our thermal and power consumption numbers are very different from other publications, here's some clarification on our board settings:

-Multi-core enhancement: Disabled
-SVID behavior: "Intel Fail-Safe" / Intel's default
-XMP: Enabled
-All power duration and limit settings default
-Core multiplier at defaults
-Core voltages at defaults

Cooler: Corsair H115i w/IC Graphite thermal pads

The performance numbers we got were double-checked against Intel's engineers, and they were in line; This suggests that our thermal tests are indicative of stock performance (with motherboard vendor optimizations disabled). We did not ask Intel about their thermal or power consumption results.

No mention of motherboard used for the other CPUs + chipset has more power use on Ryzen. If you wanted a proper comparison you'd need EPS12V power with a motherboard packing comparable VRM of >90% efficient powerstages (i.e. Crosshair VII Hero , Taichi using NexFETs, STRIX X470-F , Prime X470 Pro, or X470 Gaming 7) as the OC3D review uses Z390-E STRIX board. Most midrange Ryzen boards are using powerpaks ~85% efficient which only lower end Z390 boards use.

I don't bother with Linustechtips because I prefer reading and besides that he has no details on test methodology.

https://www.anandtech.com/show/13400...600k-review/21
~166W for i9-9900k , i7-9700K ~ 123W, R7 2700X ~ 119W

https://www.hardocp.com/article/2018...n_cpu_review/5
~158W for i9-9900K , R7 2700X ~121W


https://www.techpowerup.com/reviews/..._9900K/18.html
180W required for no throttle in AVX load : "Instead of 4.8 GHz all-core (180 W), it was running at around 4.1 GHz when left at stock TDP."

I'd be very wary of any result citing over 23% advantage in a non AVX2 multithreaded workload.

My R7 2700 @ 4025 and RAM @ 2400 gets 1826 in CH15. Something's off.

Will leave this to you, perhaps you learn something. You work for Intel ? Look´s like.

If you install a 9900K in any motherboard and disable the "manufacturer optimizations" it will run with the 95w target the way Intel intended it to run. It's an issue with motherboard manufacturers not the 9900k. I've been against MCE ever since it was released and now that Intel set the PL2 to go up to 210w doesn't mean that the manufacturers should set it by default to run that high. Hopefully they have warnings in the box of their motherboards they ship that say the 9900k won't run anywhere near Intel's target since we decided to run it at peak boost instead.

I'm sure you would be in an uproar if motherboard manufacturers started clocking AMD chips high just cause those chips could.

Well... He had to defend intel on every post cos he was probably paid to do so.

He is beyond even what a typical hardcore fan will do. More like he is someone from Intel.

jclafi , did you notice the Intel XTU shows 187W or so package power? His graphs show 150ish watts only

Pfft, Intel will NEVER do that. They're the KINGS of anti-competitive play. You've gotta be crazy to think Intel is innocent in this. They know full well what goes on here. Did you not see the fiasco with Principled Technologies?

Intel are just as dirty as any motherboard manufacturer.

Just butthurt AMD fanbois sounds like to me. Instead of constantly bashing Intel maybe you guys should jumping AMD for producing a slower product with literally no OC headroom. Personally i could care less that the mobo manufactures have better settings and higher TDP over Intel specs. Get over it, move on buy what you want.

You sound like a butthurt Intel fanboy.

If all Motherboard makers were enforcing by default the 95W TDP limit, you would have cried a river. Because the gaming performance of the 9700/9900K on stock would have been HORRIBLE due to throttling.
