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?
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…
> ... none of these Consumer CPU upgrades interest me anymore What about the Ryzen 3000 line up? The benchmark leaks make it seem like it is going to be a huge improvement and AMD isn't susceptible to Zombieload.
Looking forward to a less complex architecture even if it means cutting me off at the knees with execution speed (for a few years):
RISC-V
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.

Sure, but we all take risks every day. If you're worring about turning-complete CSS files exploiting Spectre and Meltdown then you probably don't leave the house much.
We know that attackers have reason to exploit literally all compute resources they can find a way to access. This is more like worrying about leaving the house during an epidemic of exploding ebola-infected pigeons — if you can do something about it, you should.

It's not just Anandtech. I feel like the entire "PC enthusiast" review space has dropped the ball on hardware vulnerabilities. Reevaluating performance between microcode and OS patches is an afterthought, and when a new CPU hits the market the numbers are presented without the obvious disclaimer that these performance gains may evaporate within months. Some even perpetuate the "only relevant to datacenter" myth despi…

Why would you need 1GHz for writing, e.g. in vi/Emacs? 1kHz I'm not sure, but 1MHz should be enough.
vi? Probably. But not Emacs, although I guess you could run something like Linus's Micro-emacs. https://git.kernel.org/pub/scm/editors/uemacs/uemacs.git/
In all cases, anyway, a 10 MHz 68030 should be enough for full Emacs, it's commonly seen as the lowest hardware requirement for a useful workstation Unix.

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…
Since it's turbo, I thought it means "as long as the CPU likes it", rather than indefinitely. Or did they change how turbo works and now it's "it will run on turbo frequencies as long as there is enough load and the CPU is not temperature throttled"?
> Base frequency is when the Tau moving window time has expired. How most modern high end motherboards set it to an effective unlimited time.

> To simplify, there are three main numbers to be aware of. Intel calls these numbers PL1 (power level 1), PL2 (power level 2), and T (or tau).
> PL1 is the effective long-term expected steady state power consumption of a processor. [...] PL2 is the short-term maximum power draw for a processor. [...] Tau is a timing variable. It dictates how long a processor should stay in PL2 mode before hitting a PL1 mode.
> This is where it gets really stupid: the motherboard vendors got involved, because PL1, PL2 and Tau are configurable in firmware. [...] This lets them set PL2 to 4096W and Tau to something very large, such as 65535, or -1 (infinity, depending on the BIOS setup). This means the CPU will run in its turbo modes all day and all week, just as long as it doesn’t hit thermal limits.

pc enthusiasts aren’t really into running javascript either.

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