Linux 5.5 Should Bring Another Power Management Improvement For Intel Ice Lake

More like expanding the term TDP into something more complex while marketing a lower number.
But yeah. Lies.

TDP is not complex, just measure full CPU power draw with a massively oversized heatsink so you get the max power draw in optimal conditions.

Main difference is that now they are blatantly lying about TDP, so they are not as easily perceived as such.

More like 'again'. I still shudder thinking about the dreadful Pentium 4 days, with 115 watt TDP 32 bit single core cpus. Meanwhile, AMD had full 64 bits, higher IPC, lower TDP, and lower price, with the Athlon64.

A welcome addition. Since,
"Intel Inside"
has become more of:
"Intel - Waste heat Inside" lately.

Ice Lake and heat - with that minimum of TDP - as being used in ultra thin laptops only?
I would like to see an Icelake desktop CPU in the range of 35-65 W TDP and 8 cores without HT ... but that will stay a dream.
At least it would be capable of 4k STK fluently - and not FullHD not so fluently ... cough ... as on a six year old Haswell ... cough ...
They are still selling those DP 1.2 and HDMI 1.4 (like Haswell being 4. Gen CPU and Gen. 7.5 GPU of more than 6 years of age)
with their current Gen 9 desktop CPUs with Gen. 10.5 GPUs and similar mitigations at place.
It remains to be seen if Icelake will ever be used in the desktop ... maybe its successor ... maybe ...
Intel won't tell ... till it is released ...
