Glad to have AMD Ryzen...MacOS should start using AMD Ryzen processors too in the near future to lower those dramatic prices.
Nope. No thunderbolt and Apple will charge the same for slower performance from Ryzen. Paying the same for worst performance is silly. Even sillier is the fanboys wanting ARM instead. Say goodbye to software library and 3rd party support like the awful PowerPC Macs. Apple’s MacOS doesn’t have the influential power as iOS in the mobile world where their OS eats first before the competition. In the desktop world, they’re the second fiddle like Android that relies on ports from the big dog.
 
Slowdowns you say? Maybe my MBP will see improved battery life. ;)

No, the CPU will need to spend this time keeping data safe. The CPU will simply be wasting this 5 to 30% of it's time doing that, leaving less for real tasks.
 
Wow it's absolutely hilarious to watch all the arm-chair computer experts on these forums jump to conclusions. Similarly poor form on MR to post this to front-page until more info is officially released. Based on the info floating around in the last few hours, there appears to be minimal impact (if none) to the majority of normal users, including gamers. Albeit on linux, gaming results pre/post are basically identical with no impact:

But go ahead everyone jump to conclusions and complain before you even know what you are dealing with.

Perhaps those in the big boy cloud server world will have an issue on their hands, but at initial glance the majority of users will see zero impact so let's just wait and see how this thing plays out.

If cloud servers are greatly affected then the end user will be too; with also the issue of their own computer.

However I do agree let’s see how this translates to real world performance hit.
 
I'm admittedly not well versed in ARM, but why can't Apple put lets say a bunch of these into a system working in unison? I'd expect the future isn't necessarily high clock rate ARM processors, but instead multiple processors, better algorithms, load balancing.

That's not how anything works. Synchronization can create a lot of overhead, and even then some problems just have long dependency structures. It's not just multithreading. You make the assumption that meaningful work can be assigned to a large number of cores just by making tweaks to the methods involved.
 
So, does this mean the 2010 MBP 17 inch has the design flaws ?
Good question. I hope we get some more information soon to see how far this goes back. Some of us who still have older computers might be happy we kept them...
 
After 5 yrs working for Apple, I can finally post again instead of lurking... Here's my contribution

1) arm CPUs are significantly simpler than x86-64, so less opportunity for bugs
2) Apple has better chip designers. I know many of them from my days at AMD and exponential and other companies. They’re very good.
3) if broken they can spin a fix faster

Do you want a lollipop?

Apple need someone to blame when things go wrong. They always have. They will never make the CPU's in house. They'll have no one to hide behind when it goes tit's up.
 
Wonder if Apple will sue Intel, and get better chips from the settlement, in proper time instead of the delayed manner it happens now?

Qualcomm must be very happy.

What was the point in the lollipop part????
 



A serious design flaw and security vulnerability has been discovered in Intel's CPUs that will require an update at the operating system level to fix, reports The Register. All modern computers with Intel chips from the last 10 years appear to be affected, including those running Windows, Linux, and macOS.

Full details on the vulnerability aren't yet known as the information is currently under embargo until later in the month. The Register has unearthed some data, however, and it seems the bug allows normal user programs to see some of the contents of the protected kernel memory.

This means malicious programs can potentially, in a worst case scenario, read the contents of the kernel memory, which can include information like passwords, login keys, and more. It's not yet clear how severe the bug is, but The Register speculates that it's significant given the rapid changes being made to Windows and Linux.To fix the bug, the kernel's memory needs to be isolated from user processes using Kernel Page Table Isolation, which could cause a performance hit on some machines. According to The Register, Linux and Windows machines will see a 5 to 30 percent slowdown once the fix is in place.

It's not yet clear how Macs will be impacted, as there is little information available at this time. Software updates are in the works for Linux and Windows, and though not mentioned, Apple is also likely working on a fix for the issue.

Full details on what's known about the vulnerability can be found at The Register, and additional information will be available later this month when complete details on the design flaw are shared.

Didn't Intel announce this back on November 20-21st?

This is just dumb, Apple already designs CPUs in house.

This take makes no sense as the vast majority of devices Apple ships feature a CPU designed in-house by Apple. This has been the case for half a decade. Clearly, "having no one to hide behind when it goes tit's up" isn't a major consideration here.

The only question is whether Apple can, and needs to, do better than Intel for the Mac.

The good news is that you also have to subtract 30% from the one from a few years ago since the intel bug has been there for a decade :)

Not really... maybe my 5-year old macbook (which I can’t update to new macOS but I manually upgraded with an SSD) will result faster than the new one.
 
So is there any major class action law suit set up in Canada yet?







Thanks !
