Just curios other than something requiring quicksync is there any software optimized to run better on Intel than they would on Amd cpus? (virus, virtualization, web browsing etc etc) Minus all the synthetic benches other than gaming @1080p what benefits would someone get from choosing Comet lake over Amd?
Please no heated arguments. just want a list of Comet lake strong points.

Matlab or anything that uses Intel MKL.

all windows OS 's dont support nested virtualisation with AMD processors when they are the base hypervisor '( vm within vm).
KVM, esxi , AVH all support it fine.

Gaming and photoshop, as long as your intel CPU is sustainably clocked at least 200-300 MHz higher. Otherwise no, not really. Otherwise it's always a beating, and in productivity, a smacking.

I went through around the web in my country and found almost no CometLake Pentium on the shelve(G6400-G6600), will the Pentium coming later or just supply shortage in my country?

it was the same with coffee lake refresh pentium and celerons, who would buy a 2 core processor in 2020 when you can buy a 1600AF or even 1200AF for the same price? paper lauchs.

Another thing I like about my 10900K on the Z490 is the memory stability. I'm able to eek out an extra 50MHz (100MT/s) on the platform. DDR 4000 16-18-18-560-2T @ 1.45V totally stable with 24+ hours of stability testing. With only 1.2V VCCSA and 1.15V VCCIO

Intel has been prioritizing production of high dollar, high profit CPUs for the last couple of years:

Newsroom Home

Intel Newsroom home page
newsroom.intel.com newsroom.intel.com
"We’re prioritizing the production of Intel® Xeon® and Intel® Core™ processors so that collectively we can serve the high-performance segments of the market." - Sept 28, 2018

Intel: CPU Shortages Will Persist Throughout Q3 2019

www.anandtech.com www.anandtech.com
"Although Intel invested some additional $1.5 billion to boost its 14 nm fab output last year, it looks like its supply problems are not going to be solved until the second half of this year...Due to obvious financial reasons, Intel prioritized production of high-profile products like Xeon or Core i7/i9 over manufacturing of lower-end products, such as Atom, Celeron, or Pentium." - Apr 26, 2019

Intel Forecasts 'More Normalized' CPU Supply In 2nd Half Of 2020 | CRN

Intel's CPU supply for PCs and servers is expected to meet demand by the second half of 2020.
www.crn.com www.crn.com
"Due to greater-than-expected demand for PC chips, the company began seeing supply constraints for the CPUs in mid-2018--and the issue has persisted...But for "server CPUs, we really prioritize that and try to put ourselves in a position where we're not constrained. And we're in pretty good shape," Swan said." - Jan 23, 2020

Until Intel supply can meet booming demand, there will be a shortage of the Pentium processors all over the world.

Sure enough it looks like Intel might start to supply the 9700K and 9900K again. Usually it's effectively discontinued when the next K product is released. Guess the 8 core die that Comet Lake H uses can't be used as the 10700K. It's enough of a supply that the 9700K is skyrocketing up the charts at Amazon.

That's weird. They're using the 10c die for the 10700k?

If You are looking for a 10900k and have a MIcrocenter near you check it. The one near me in PA has over 10 in stock. Bad thing is they now have it priced at $599.

It is outright incredible platform for OC and memory OC. Of course components need to be top end, but I am getting some real nice results: 1.44V mem / 1.15V SA / 1.15V IO => 3866CL15 with 4X8GB DRAM is amazing, and secondaries/tertiaries are as tight as i want them to be:

Won't break world records, but for daily driver it is smoothest system I've ever had.
And OC was uneventful, unlike X570 or Z370 tuning, where corrupted BIOS / Windows are not out of question when working near the limits.

Hard to tell without measuring. But i feel that old systems will receive microcode updates either by BIOS or distributes by Windows updates / Linux. It takes extra effort to avoid those microcode updates that hurt perf.

I did a quick run in Speedometer2 web test and performance seemed to be in order ( 8700k 4.8 => 10900K 5.1, while perf went from 144 to 152 ).
So probably IPC is virtually the same, just more workloads fit the L3 cache now and therefore everything is smoother and "minimums" are higher now.

Subjectively 10900K is smoother, but it also got fresh Windows install.

In fact after toying with it I think I will disable HT completely, that should result in fastest desktop machine possible right now with zero dependence on Windows scheduler.

My understanding is that the hardware-level fixes usually hurt performance less than microcode patches and OS-level patches.

Oh yes, these updates come through in disguise like ninjas if you are not careful enough.

The L3 does benefit some apps that's very true. What about the WinRAR internal benchmark? Thanks.

Well, personally I can even notice 10% of extra snappiness in a browser, so I get what you are saying.

That would be a smart thing to do, imo. It should run cooler and be slightly more power-efficient, let alone yield potentially higher performance, I know that some games do benefit from that.

You are correct, still am I not surprised to have seen literally none of the same clock head-to-head tests done against the older Skylake architecture CPUs. Reviewers must have been really fed up :p
