Better Off Alone Edition
- Intel's Core i9-9990XE can hit 5.0GHz on all 14 cores. (AnandTech)
It runs at 255W and costs around $2000 if you're lucky enough to find one. They're sold to partners only by special auction and in limited quantities.
Or you could buy a 32 core Threadripper.
- Intel's Core i9-9900KS can hit 5.0GHz on all 8 cores. (Tom's Hardware)
It runs at 127W and costs $513, will be on sale for only two months, and carries a one-year warranty.
Or you could buy a 12 core Ryzen.
- The US Senate has put a hold on a terrible horrible no good very bad House copyright act. (TechDirt)
The House bill legislated a streamlined copyright infringement process that could slap people with up to $30,000 in penalties without messy technicalities like due process.
Ron Wyden and Rand Paul, thanks.
- Begun, the 10nm era has. (AnandTech)
Only four years late.
- Ryzen 3000 had a bug in a specific random number function. AMD pushed out a BIOS patch. Motherboard manufactureres released updated BIOS files. Only some of them forgot to actually apply the patch. (Ars Technica)
So even if you are completely up to date you might still have the bug.
The bug can do nasty things to Linux security tools, which check that the random number they get from the CPU is sufficiently random, and keep asking for more random bits until they're satisfied. If the bug is present and unpatched the number never gets random enough, so the system completely locks up.
- On the other hand, if you have the patch, the problem is solved. That's a lot less true for Intel's speculative execution bugs. (ZDNet)
If you're running untrusted code on an Intel server (shared hosting, virtual servers) just disable hyperthreading already. It's the interesection between speculative execution and hardware threading that produces most of the bugs, and you can't turn off speculative execution.
Video of the Day
The article mentions the price being $2800. I pointed out in the comments that there's been a price cut (to the $2000 you mention) but they haven't updated the article.

That makes a sidegrade from my 3600X to a 9900KS really tempting, but it probably wouldn't really be worth the money.

The same for the 9990XE if it were a regular product with guaranteed availability, although costing twice as much as the new 18 core Cascade Lake X part makes it very niche.

I'd need some way of verifying GW2 would get better frame rates before I'd replace my existing system--for example, someone running that CPU with an RTX 2070, and checking their frame rates during a particular world boss, to see how it matched my system.

Here's an Amazon link that probably has an affiliate link in it. It's 540USD.
