Whenever you think of mobile computing, Arm is likely the first company that comes to mind, or it should be. Billions of Arm chips are used on phones, TVs, embedded systems and tablets. But they're coming for more.

Nope. Not true. Because RISC instructions execute much faster, complex CISC instructions can actually be a lot slower, especially in case of wrong branch prediction, since numerous and irregular length instructions may take a lot more time to decode. And take up a lot more space on silicon. A RISC CPU has more internal super-fast registers, where the compiler can store local variables into, making tight loop execution a lot faster.
Not to mention that CISC CPUs have lots of unused legacy instructions that just occupy space on the silicon, prolong development and testing, and serve no purpose. RISC has no extra instructions, it's got just those that are needed.
So, the comparison is this: CISC can perform complex tasks by executing less instructions, which take more time, while RISC will do the same job by executing more instructions that take less time. The end result is approximately the same, but RISC is simpler to design, cheaper and can have lower energy consumption.
In other words, Greta would be happier with RISC CPUs.
Intel seems to have stood still while counting the benjamins for the last five years ...
What Nvidia owning ARM wil do for the adoption and continued use , who knows ..?
I suspect many Co's would like a more "open source" type solution ..maybe we will see some sort of adoption of RISC-V by some diehards.
AND WHAT WILL China and Russia cook up in their LABS ? Some major companys are still running Cobol programs on IBM mainframes .... they could run better on a Pi400 , but ....
Yeah ya ya, Blah bla blah
I've heard enough propaganda on what Arm can do
Exactly my thoughts for the past 60 years people have been trying to say RISC was going to take over everything, news flash it was only useful in smartphones and tablets where battery consumption is a thing, performance per watt sure but that's the only contest it will ever win. It's laughable people think it can take on high end x86, the M1 is 5nm right so it matches performance of a budget 22nm chip from over a decade ago.......big whoop. The fact it's locked down to Apples OS means it's worthless in testing, anyone can build a half-assed chip arch and run optimization like hell on it and get decent performance, the gaming consoles do it and get low end high teir visuals from budget hardware the only thing legendary here is peoples misconceptions.This. I'm getting really tired of all the pro-ARM propaganda in tech media, which seems to have been ramped up to 11 in 2020. Not only it's been annoying, it seems unnatural and fishy.
The USD$40 Billion spend by purchasing ARM by Huang will prove to be cheap. Indeed NVIDIA has now other (much bigger) plans and visions. Huang (CEO) earned his Master's degree from Stanford University. Sincere congratulations to a USA Immigrant. After Stanford he worked for AMD as a Microprocessor Designer and 'key executive' and getting even smarter. Now Huang at NVIDIA is drawing down an annual salary of USD$26 million along with stock options doubling this amount. He is a bilionare 12-times over. Certainly the entire "RTX 3000" effort and since the arrival of ARM is not anymore Huang's primary business objective. His company went public in 1999, shares priced at $19.69 each. An investment of $2000 and your initial capital with reinvested dividends would now have grown to $291,000. Both AMD and Intel will be in for ride of their lives coming soon to this theater thanks to Mr. Huang. His early impressionable work at AMD tought him well and how to move in a corporate American world. In a recent Taiwan Financial Times interview he remarked: "The ARM purchase was a major turning point for NVIDIA and a shift in our corporate culture. We are now standing at the threshold to growth heretofore unimagined and an opportunity to be one of the most technological and progessivily advanced companies in this world."Intel seems to have stood still while counting the benjamins for the last five years ...
