USB 4 has a direct PCI-E bus support, but it’s optional in USB 4. It’s mandatory in TB 4.
You will find Apple's goal is to gain a lot more than 20% new Mac customers.
The corporate world is running Wintel apps using Citrix. Which runs better on a Mac than on a PC. Which will run even better on an ARM Mac.
I think just like today, there will be different chips. If you ignore MacPro and iMac Pro for the moment, you can buy Macs today with 2, 4, 6 and 8 cores. I'd expect three fast cores like the iPad to replace all dual core and some quad core Macs, six fast cores replacing everything up to 8 cores, and eight fast cores to exceed the fastest non-pro specs today. (Plus four tiny cores on every chip; having more than four doesn't make much sense).
Imagine I built a VM for Linux ARM. And then I ran MacOS ARM in that VM. That MacOS ARM would have Rosetta built in, and therefore would be able to run all MacOS Intel applications. On a non-Apple ARM computer running Linux. Now instead of this build a Linux ARM computer with Rosetta built in. That could just run Linux Intel code. And you can take this and put it into an ARM VM running on MacOS ARM. And it can run Linux Intel apps on an ARM Mac.

So , am i understanding well or not , can you help me ?
Separately, Federighi acknowledged that users were concerned about the future of running Windows on Macs that are based on Apple Silicon. "We're not direct-booting an alternate operating system," he said, confirming that Boot Camp will be run on the new Macs. However, he implied that Windows will be able to run under virtualization. "The fact that we mentioned virtualization in the keynote was partly a nod to people's interest in the topic."
Apple's Federighi and Joswiak discuss Apple silicon, iOS 14, Big Sur and more | AppleInsider
In what has become an annual event, Apple SVP of software engineering Craig Federighi and VP of product marketing Greg Joswiak sat down with John Gruber to discuss the new products, innovations and services announced at WWDC.
Right, but ARM Windows like this [edit not an ARM]:So , am i understanding well or not , can you help me ?

That is a very long-winded way of saying that it is possible to build an x86 emulation layer for ARM.
Sure it's possible. But the performance will likely suck, and it will not support all x86 instructions (e.g. Rosetta does not support AVX vector instructions), and it will very likely have a number of incompatibilities. Rosetta will also likely not just emulate the CPU, but also translate certain system calls to the native ARM MacOS to get at least reasonable performance, which would have to be redone for Linux. Now put yourself into the shoes of a developer targeting Intel platforms, for whom time is money. Would they really want to deal with these issues and add additional testing to make sure the code runs on the actual target platform instead of just switching to an Intel-based machine for development? Or go through the effort of building multi-architecture containers for the miniscule number of Mac users that use containers?Strongly agree - what I really don't undersand is why people seem to think that a stagnant Intel CPU roadmap only affects Apple. After all, it's not like anyone else is coughing up faster Intel laptops... At least the products are mature and relatively stable - Apple CPUs will likely continue thier annual release cycle, resulting in people just having to buy new laptops every 2~3 years. Which I guess was the point.
Is it? Personally I develop NFV software for a Linux-based cloud environment that runs on x86 CPUs (like 95%+ of cloud servers out there). Data plane performance optimization using things like AVX is a big part of it. Macs today are very popular among developers in my field in part because it's easy to run x86 VMs and use tools like Vagrant.
I doubt that very much. With its current generation ARM CPU, Apple has closed the gap, but is still slower (sometimes dramatically) than Intel in most single-core tests (see e.g. here). They will be able to benefit from very tight software/hardware customization for specific tasks, and maybe keep an advantage in the performance/watt ratio thanks to TSMC's better process, but that is less important for computers than it is for phones and tablets, and may be short-lived anyway as Intel's "Tiger Lake" with their new process comes out later this year (which supposedly also has a much improved iGPU).
