Intel has fallen so far. It's honestly a shame to watch at this point. I remember back when Sandy Bridge was first released, and I was extremely pleased by the performance improvements my new chip was able to provide. Did they really manage to mess everything up within such a limited timespan? Or was there just always a hidden incompetence that never showed itself until now?

Their design for 10nm and the implementation didn't line up. Whatever their (still undisclosed) problems were, the entire node was fundamentally flawed. It might have been hubris at having been at the cutting edge of fab tech for so long. It could have just been the fruits of pushing the envelope - sometimes what you predict will happen when you put theory to application proves false. It has warped their business hea…

I more and more tend to believe the rumors (started by Semiaccurate) we will not see 10nm in mass quantities and 7nm is the next. We will see very, very soon: Intel said 10nm CPUs in client systems will be on shelves for the 2019 holiday season.

I used to be Pro Anandtech and consider them one of the best Sources online for Hardware News. But the fact they have yet write a single post, big or small about Intel's Zombieload and its implication on performance worries me a bit. Then there is the "Intel" benchmarks as usual [1] on GPU. Trying to suggest the 2 CPU were both running at 25W TDP to give a "fair" comparison, without mentioning the Ice-Lake U CPU were…

Benchmarking cpu firmwares is forbidden by the license (same thing for databases)

And yet they still have the lion's share of the market. And the money to eventually recover from this as if nothing happened. Tell me when they have really fallen. Still very far from it.

That means very little. As the saying goes, “How did you go bankrupt?” “Two ways: gradually, then all at once.”

In technology, downward swings of fate tend to come fast and hard. The camera world went from 100% film to 100% digital in the space of about five years, which extinguished Kodak. Or consider Palm/Nokia/ Blackberry, who went from collectively owning the entire mobile market to dead as doorknobs in even less time.

It’s easy to see how it happens to Intel too: AMD’s big-core-count chips start eating up server business, while ARM takes over PCs (at this point people consider it all but certain Apple is switching to ARM in the next few years, and Microsoft is building Windows on ARM as a hedge), and without another business for Intel to fall back on (they’ve shut down modems, mobile chips, and anything else that could’ve been a new source of revenue), that’s the end.

I’m not saying it’s certain, but I’m saying it’s totally possible and their current market share means nothing.

I would setup a scenario where safety is a concern (V2V) so you could get court order to benchmark firmware.

What does stability mean, a bit more exactly? Just curious

The switching speed of silicon has also some upper limit. When you drive silicon faster, it starts to make mistakes. i.e. not all electrons go the where you want them to go. This causes soft-faults and CPU re-executes the part at best, or gives you a BSOD, oops or panic at worst. This upper limit depends on process, layout, power design and power limits of the CPU. Last but, not the least, not all CPUs are created eq…

>gives you a BSOD, oops or panic at worst.

That's not too bad. I'd be much more worried about code silently doing the wrong thing .

IMO this is only a repeat of the AMD Athlon days and Intel will go back to their anticompetitive antics sooner than later.

Why 5 Hz all the time? I'd love to have such an extremely powerful CPU but I'd actually appreciate if it could downclock itself automatically and stay as cold as possible whenever I don't need it's full power. Some times I run heavy computations and having 8 5Hz cores sounds great but most of the time I just read or write something so even 1000 Hz sounds an overkill.

> 5 Hz

> 1000 Hz

You must have meant to say 5 GHz and 1000 MHz...

Should they be describing it as 8 cores 16 threads when there have been multiple security vulnerabilities that have to turn off hyperthreading to be mitigated?

Besides cloud providers running VMs /containers on the cloud, is Spectre/Meltdown really such an issue for day-to-day consumers ?

Given that most consumers run JavaScript unconditionally, yes. Browser vendors have basically declared Spectre/Meltdown/MDS unmitigatable at the browser level.

Yes. I think this is a common misconception. These attacks work fine in the browser, as researchers continue to show. They allow complete bypass of any native app sandboxing layers. Surely you don't run everything on your box as root all the time.

I'll keep HT on because I use NoScript and I encourage others to do the same.

Meh. It doesn't require Javascript for your computer to run logic described by others. Browsers are such complex machines that it wouldn't surprise me if you could for example craft a malicious SVG that would bypass that, or a turing-complete CSS file that triggers a vulnerability...

By the way, does NoScript actually block in-SVG javascript?
