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.

Base frequency isn't the same as lowest frequency (ya... it's weird). Base frequency is vaguely related to the idea that if you had all cores running at the base frequency, you would run just about at the system's TDP (it's really a complete mess, this is a simplification). Your system can still drop CPU cores down to 400-800MHz in low energy states. What this announcement is basically saying is that Intel now has a…

Not indefinitely just at the same time because thermal throttling will happen after sometime. It just means all cores will be able to go to 5Ghz at the same time nothing about all being able to stay at 5Ghz

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 .

That happens too. Prime 95 and other stability tests are used and can check when wrong results are returned. There's often a sliver of frequencies where a system under load begins performing floating point calculations incorrectly while other, simpler systems in the CPU are still functioning correctly.

The BSOD, oops, or panic is a symptom of widespread errors.

From how Apple and AMD are doing with their own processors though, it seems like Intel is just fundamentally doing worse even as things become more difficult with smaller transistor sizes. Apple is going to replace Intel with their own processors because Intel has failed to meet requirements. AMD, with a shoestring budget basically on the verge of bankruptcy the entire time they were doing their R&D, managed to build…

Intel was ahead, and hit the wall first. Apple & AMD are not ahead, they're just catching up. I don't want to understate how big a problem that could be for Intel, of course. But they're also doing it on low margin parts, and Intel continues to make bank with their data center parts. I don't think any of this represents a short-term problem for Intel, other than the general downturn in processor sales because fewer p…

If the speculation about AMD's Rome / EPYC 2 performance is true, they have now surpassed Intel.

pc enthusiasts aren’t really into running javascript either.

I've seen a number of comments like this over the last few days and I don't really get it, gamers use the internet right? Vast overwhelming majority of them are going to be running javascript programs hundreds of times per day

sure, and maybe browsers or os need some way to say “running untrusted code please turn off performance for a sec” for that use case. until then ill just use one tab at a time or disable js before i opt in for slow.

Intel quickly walked back that crap

Apple sold millions of iPhones with 7nm chips while Intel struggles to build comparable 10nm chips and keeps releasing 14+++ nm. AMD will release 7nm chips very soon. It does not seem like they are catching up. Quite the opposite.

You can’t compare nm between vendors - it’s just marketing numbers.

Not directly no, but the actual feature size and density of TSMC 7nm and Intel 10nm are comparable.

From an interesting historical perspective, I mark the end of Moore's Law in 2001 with Intel's prediction of a 5GHz "Netburst" in 2005, which could not keep itself from melting. Somewhere I have a marketing road map of 5GHz in 2005, 10GHz in 2010. It was aspirational of course, but seeing what had to happen between then and now in order to get a chip that runs at 5GHz all the time based on their architecture is illum…

That's an overexaggeration, IMO. Moore's law didn't really start losing steam until 2014-2015.

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?

in-SVG javascript only gets executed when viewing a SVG document (and maybe an svg docuemnt), not when viewing an SVG in a img tag.
