Meltdown = Variant 3:

Variant 3:
Cortex-A75:

Variant 3a:
Cortex-A15
Cortex-A57
Cortex-A72
I think A75 was not shipping at disclosure time, but it has been since then.

ARM believes no software mitigations are needed for 3a.

I understand Apple does not license designs anymore, so what is vulnerable would be secret.

You can see why Apple wants to move to ARM - x86 is at the end of the road.

Both intel and Microsoft still seem to be a little lost in this this new world. Intel seems to be mired in x86 and Microsoft are making bets all over the place to see what sticks.

For all of their faults, I hope they recover.
 
Laptop is not suitable for that. Many desktops won’t have liquid cooling, or the price could be high. Maybe also server racks.
I could see laptops not having it, but for desktops and some server configurations, liquid cooling would work. It's not that expensive any more. A kit to convert my existing desktop to liquid cooling is only $100 or so.

So liquid cooling on not only CPU? Cause all other chips need cooling off as well. I did not remember there were a lot of liquid cooling GPU 3-5 years ago. Not sure now.

Oh, I was speaking specifically of CPU, as I wasn't sure we were at a speed limit on the GPU side (yet). There are liquid coolers for GPUs but I have not priced them out.
 
Why haven't chip manufacturers moved away from clocks? As they get smaller they can go much faster than clocked chips.

Self-timed logic has been kicking around for a couple of decades but it’s very hard to make it work right and more importantly it is inherently insecure - think about spectre and other recent attacks. In asynchronous designs the time it takes operations to complete depends on the data. So you can easily figure out what the data is by timing how long it takes to complete operations.

I prefer a top-down air cooler. Too much overclocking consumes a lot of power anyway.
 
While the technology advantage seems to be slipping for Intel, they have made some recent high-profile hires
Jim isn’t going to help their fab troubles. Also, people seem to be giving him credit for things he didn’t do. I see press reports giving him credit for things he didn’t do for Opteron at AMD, for example. (I was there, and Jim seems to get credit for stuff done by the cto, for example.)

He’s a very bright guy. Really knows buses better than anyone else. In the years since I worked with him I’m sure he’s gained additional expertise. But I don’t think he’s going to save intel.

Hmmm thank you for sharing your experience. That's similar to the impression I got reading the bio/wiki about work he was involved in/around.

From my own fab experience, I know some executive hires in product design will not catch them up. But you never really know what could come of it. I'm expecting we will see more diversification away from CPUs as IoT and the current trends are really all about smartening things up, getting sensors and WiFi in them, than it is about local processing power.

OK. But liquid cooling system could break the wind flow and lower the efficiency of the thermal system when cooling other components. It is not the best solution.
 
Apple just disclosed one of the problems. It was secretly fixed with the last update.

https://support.apple.com/en-us/HT208742

Kernel

Available for: macOS High Sierra 10.13.4

Impact: A malicious application may be able to execute arbitrary code with kernel privileges

Description: In some circumstances, some operating systems may not expect or properly handle an Intel architecture debug exception after certain instructions. The issue appears to be from an undocumented side effect of the instructions. An attacker might utilize this exception handling to gain access to Ring 0 and access sensitive memory or control operating system processes.

CVE-2018-8897: Andy Lutomirski, Nick Peterson (linkedin.com/in/everdox) of Everdox Tech LLC

I am beyond excited that you have absolutely NO say so when it comes to this situation. No one benefits from a lack of completion. Especially as Intel is not the only one affected. ARM and AMD are affected as well.

Did they cover it up though? Act as if it was just a normal day? They didn’t.

Intel acted like a babe in the woods about it. Keep defending them but the court of public opinion will rip them to shreds should that happen again.
 
Maybe humanity is hitting the climax of CPU advancement... I just don't see how a faster processor will make the lives of everyday consumers any better. We currently can do everything we want just fine from browsing to office work. It seems like more emphasis are put on effeciency as they want products to draw less power and smaller in size.

So let me guess, with that logic, were you not mad at Apple for hiding the throttling and several other hidden "gems" they have kept from the public? Kinda odd to slam one company but embrace the next one with worst practices.

Let’s not bring whataboutism into this. The subject is intel and I feel how I feel and no one is going to change that.

And I replied to that. It is beyond stupid to want Intel to fail. Statements like that are ridiculous to say the least. There is no logic behind it.

Unless you believe in the "what is a computer", you would be directly affected as Apple deals with Intel mostly, over AMD. Don't believe me? Look into the majority of their hardware after powerPC.

That’s your opinion and this is a free country and I can think whatever I want thank you very much.

Once Apple makes their own desktop and laptop chips they won’t need intel which is going to happen sooner than you think.

Intel is garbage.

Intel is better than any garbage, throttled chips that Apple could ever make.
