This equation gives good estimate of power. From voltage alone, a 20% increase in voltage causes a 44% increase in power.
Assuming similar Cdyn, going 2x freq and 20% higher voltage is 2.88x increase in power.
Thread Director sets a precedent that AMD can probably just copy or modify. The Intel Bridge tech for Android apps in W11 works for AMD as well. They could have locked it out. Overall I think all of these innovations are good for the ecosystem.
Senior positions usually make the big decisions and set direction. Setting the wrong direction can set any company back by years.
But agree that deep technical details probably not.
You mean this group which posted a job ad? https://www.themuse.com/jobs/intel/cpu-rtl-design-engineer
Seems like from LinkedIn it was formed in 2019. The question is who was their boss when it was created. (https://www.linkedin.com/in/debbie-marr-1326b34)
People here mentioned that the base frequency has increased by >500MHz? If I’m not wrong the base frequency must be sustained on all cores and still meet TDP. Voltage will probably have to be lower at the same freq, being such a big contributor.
Taking away his exaggeration, what’s the more reasonable performance estimate?
Also what’s the delta to Zen3....he seems to be comparing to Zen2 which is not the right comparison.
It’s not -R line, it’s KBL-U Refresh (short form KBL-R). Check on the link in the list you shared for i7-8550u, it’s a KBL-R part. Quad core released in Q3 2017. My company laptop is using KBL-R and I’ve been using it since 2018.
Will we be seeing Intel and AMD designs go with significant IPC increases (>20% a year) or have we hit diminishing returns?
Is single core performance going to just rely on frequency increases while the way forward will be to add more and more cores?
Maybe he’s using his time there because it is good? There was an Anandtech article on its innovations.
I find him highly knowledgeable in so many parts of ICs design. This presentation is a gem:
