> Your points don't explain why at 3Ghz this chip can outperform 5Ghz chips in single-threaded workloads.

It's a trade off. Making it wider is the reason the IPC is higher, but it's also the reason it is a 3GHz chip instead of a 5GHz chip.

The author's explanation of why x86 processors can't do this is also not especially compelling. The reason very wide processors are atypical is that common spaghetti code has poor instruction level parallelism -- the processor can't extract what isn't there, so there is a point at which higher clocks become the way to make bad code run faster. Interestingly, synthetic benchmarks are often less susceptible to this because the code is optimized to maximize ILP. It's a shame we still have so few real world benchmarks (mostly because the applications still haven't been ported).

> The DDR4 is faster than average, but you can get those kinds of speeds on enthusiast PCs and it doesn't make a big difference there.

It depends heavily on the task, but the difference in some cases is close to 40%:

Intel fabs their own chips. AMD outsources that. Intel is still on 14nm vs AMD's 7nm. It has been a really long time since AMD has even come close to Intel. The question is whether Intel can recover from their slump before AMD can get enough chips out.
Two other points about cheating relevant to non-expert players:

- Until expert level you most likely won't to be able to notice in real-time that you're playing a cheater. You'll be blundering and getting out-positioned regularly against legitimate players, so it's hard to notice that for one game a cheater played a perfect game against you, because most likely you made clear mistakes in that game. This is different for experts because they mostly stop making minor mistakes, so they have cause for suspicion when they know they played a strong and consistent game but still got destroyed. You also won't be strong enough to really recognize that some moves are "inhuman", especially because you'll be playing against folks who make weird/wrong moves all the time, whereas experts can sometimes tell if moves are computer-like (typically because there is a natural and obvious move to make and the cheating move is marginally stronger but hard to find).

- Cheaters don't stay in low ratings for long. If they aren't detected, they'll be out of your rating in no time, like in 2 or 3 wins. This reduces the chance you'll encounter cheaters, because if a cheater plays 100 games but only 2 of them are in your rating bracket, you're unlikely to ever match against them anyways.

Keeping those things in mind, and knowing that reaching expert level (~2000+ elo) takes many years and is unachievable for most adults, online cheating becomes a minor concern at best for anyone who's picking it up as a hobby in adulthood.
But in one x86 instruction you often have more complex operations. Isn't that part of the reason why Sunny Cove has only 4 wide decode but still the decoders can yield 6 micro-ops per cycle? That single stat makes it look worse than it is in reality, I think.
We should have a carbon tax. Cryptocurrency mining isn't so awful if it's funding the development of sustainable, low negative externality energy.
GDT_TS for AlphaFold is now comparable is at experimental levels; but that's based on the class of proteins for which we've been able to determine the 3D structure of the protein, for which there might be selection bias.

I wonder if we can determine if this extends to proteins that aren't as keen to determining their 3D structure?

For example, certain proteins are more crystallizable than others.. For these non-crystallizable proteins, I wonder if we can say that AlphaFold would generate accurate 3D models? And if possible, might there be a way to map out this uncertainty?
It's not that it was more economical, but that at least some of these AMD and Intel would not benefit from due to the ISA: x64 instructions can be up to 15 bytes, so just finding 8 instructions to decode would be costly, and I assume Intel and AMD think more so than the gains from more decoders (you couldn't keep them fed enough to be worth it, basically).
Note that javascript can access whether developer tools are open and change it's behaviour. Or so I've heard.
Yeah, Apple’s CPUs have been doing really well for a while now: https://www.cs.utexas.edu/~bornholt/post/z3-iphone.html

Apple did optimize for some common use cases, reference counting (as used by objc++), javascript tweaks, and for emulation for rosetta2. However they also made a great general purpose CPU that will run many standard codes impressively quickly for impressively little power.
Congratulations! I tried a similar approach based on the original attempt at this challenge (https://www.spinellis.gr/blog/20090805/), but gave up after running it for a few hours.

Very cool that you were able to achieve this. I'd thought it was impossible while using the original method given how many more tweets there are now then in 2009.
What complexity does Poetry have over pip? This is a serious question. Yes, you have to install it on top of your Python install, but other than that?
I think they old adage, “don’t buy first generation Apple products” applies here. Seems sensible to wait to see where this goes.
So in the (excellent) article, they have two advantages: System on a Chip and enhanced out of order execution. Wasn't out of order execution implicated in Spectre and Meltdown? How are they mitigating this issue? I imagine for a new chip they could design something in.
Yeah, Heroku is awesome. I'd stay with them (despite the price) if I could run distributed Elixir.

I used to work for a corporation that made photographic equipment. Expensive photographic equipment.

They would regularly "crush" out-of-date equipment (like stuff that had passed its market prime, so the sales and marketing folks no longer needed it). By "crush," it meant taking the equipment to an old quarry, and smashing it with a sledgehammer.

Apparently, this was necessary for a tax write-off.

It was painful as hell, as most of the equipment was perfectly fine. It included things like bodies and lenses, still worth thousands.
> instructions have different lengths

also allows extremely long instructions, the ISA will allow up to 15 bytes, and fault at 16 (without that artificial limit you can create arbitrarily long x86 instructions).

Tata Consulting Services founder F. C. Kohli passes, aged 96
Sigh... my wife and I haven’t gotten this stimulus check yet. Every month, the IRS website has no update on our status. We filed our taxes early and even got our tax refunds before the normal April 15th deadline. They clearly have our information and our accountant confirmed that we 100% qualify. It’s very frustrating to hear this when we (and many others) haven’t received anything. Especially since that extra money could have helped relieve a lot of stress when I was job hunting because of COVID layoffs.

> but it does do phone stuff and does it pretty well

It does, if you have Google Services. If you don't want Google Services, you're going to have a crippled device. Apple is the only company that has any financial incentive not to spy on you, so while I don't take them 100% at their word, I accept that they're the best I'm going to get in that regard.

Basically, pick two:

- A fully-functioning smartphone

- Reasonable privacy

- Customizability
You're right. The Register article says that. The Register article says that because they're parroting Apple's marketing. I don't fault The Register for copying Apple. I fault Apple for being misleading with their arguments. LPDDR4x is NOT HBM2. HBM2 is a completely different technology.

"High Bandwidth Memory", or HBM2 (since we're on version 2 of that tech now), HBM2 is on the order of 1024-bit lanes per chip-stack. It is extremely misleading for Apple to issue a press-release claiming they have "high bandwidth memory".

HBM2 is the stuff of supercomputers: the Fujitsu A64FX. Ampere A100 GPUs. Etc. etc. That's not the stuff you'd see in a phone or laptop.

> "In other words, this memory is shared between the three different compute engines and their cores. The three don't have their own individual memory resources, which would need data moved into them."

It would be colossally stupid for the iGPU, CPU, and Neural Engine to communicate over RAM. I don't even need to look at the design: they almost certainly share Last-Level Cache. LLC communications are faster than RAM communications.

From the perspective of the iGPU / CPU / Neural Engine, its all the same (because the "cache" pretends to be RAM anyway). But in actuality, the bandwidth and latency characteristics of that communication are almost certainly optimized to be cache-to-cache transfers, without ever leaving the chip.
Because battery life.

Unpopular opinion: Cathie Wood seems to buy into whatever hype is currently trending. She does not seem to have a deep understanding as to why some of her holdings will outperform.

However, she's invested in hundreds of companies, and it would be nearly impossible to do so at that point.
Exactly in the same spot but I also need windows virtualisation...
>I didn't claim anything to be bulletproof, just saying that your body tells you when it needs water and drinking in excess of that is probably unnecessary

Yes, and it's important to listen to it, and hear it. Some body signals are subtle, and you won't hear them unless you pay attention.

Headaches, migraines, and other unignorable signals are the body screaming for help after many other more subtle signals have been ignored.

I worked in the lab that helped develop folding@home, as well as the game where the crowd was the chaotically trained machine that folded and unfolded one amino acid at a time. This feels like a pretty significant new chapter in the humanity movie.

A few times, I get immense pangs of jealousy for younger people a generation or a half before me. And I'm only 30! This is one of those times.
There's no DRAM on the SoC die. The DRAM is separate dies that are packaged close to the SoC die, but they don't have to be that close. A typical graphics card has an array of 8+ DRAM packages surrounding the GPU, with a faster bus speed than Apple's using.

To scale up DRAM capacity and performance, Apple will have to increase the number of DRAM controllers on the SoC and maybe increase the drive strength so that they can push the signals a few cm over PCB instead of less than 1cm over the current SoC package substrate. Neither of those is a particularly difficult scaling problem.

So what?

RISC-V is a specific (RISC-based) ISA.
ARM is a family of RISC-architectures, which does not include RISC-V.

Apple's M1 is an ARM SoC. It does not use RISC-V.
Teams is completely failing to replace Slack in my experience. I think it's must closer to replacing Zoom. I use all 3 daily.
Teams is strong in file storage, direct messages and video calling.
Slack is strong in channel messaging.
I would argue they barely compete, the Slack file storage and video are not great, and the Teams channel messaging is unusable and appears unfixable.
Thanks! I'll note the leading spaces bug!

No, extortion is when you threaten to hurt someone else for money. Threatening to hurt yourself for money is called, I think, livestreaming.
I'm not sure what you're talking about (pip's always done binaries for me), but I have 20.1 in any case, so...

Sometimes the stress is not obvious.
I did like having a notification LED, but I don't miss it as much as I thought I would. And anyway, those are becoming less common on Android devices too.

FWIW you can configure your iPhone to flash the camera LED when you get a notification. Not quite the same thing because it isn't passive, but it's something.
>Screenshot app has is much less easy to use compared to Mac.

It's just clicking the snip button in the action center by the clock or pressing "WinKey + Shift + S" then draw the rectangle for the area you want captured. How much simpler is screenshotting on the Mac?

You not liking some of the default apps that come with the OS(which is understandable) does not make an OS bad.

I also hate some of the apps that come with most linux distros but that doesn't make linux terrible.
Depends what they took the spectrum from I guess
Going there, I wonder whether there’s any nearby to earth rocks with large amounts of lithium. That could be a potential big thing for space industry.
Column-wide formulas are an example of Grist data being more structured than a traditional spreadsheet. In a spreadsheet, one might type over a cell because it's an exception. In Grist, you'd need to think what makes it special, and
change the formula to reflect that. E.g. `=$Price - $Discount if $Status != 'Comped' else 0`. But once that exception is turned into a rule, it applies to all records. Which is a good thing.
Hah, won't this perpetuate? Whenever M(N) is released M(N+1) will be on the horizon with even greater promise.
It's a chat app that integrates to most other services you use and ends up being the most extensive repository to all of the information shared inside your company.

As someone who pays for Slack, it would be VERY hard to make a switch. The impact of this in retention and opportunity to monetize the 'integrate workflows' increases the multiplier. Salesforce has probably calculated how this opens up revenue to their existing product line and Slack itself is growing.

I'm not saying this is science but is part of the rationale that goes into the price.
> They moved high bandwidth RAM to be shared between the CPU & GPU, but they[1] can't just keep expanding the SoC with ever larger amounts of RAM Perhaps they will have external RAM in addition to the on chip RAM, with perhaps 32GB of onboard memory and the external RAM being used as swap? This takes a bit away from the super-efficient design they have currently.

The RAM isn't on the SOC, it's soldered on the package, which is a very different proposition. Possibly so they don't have to bother routing on the board (meaning they can shrink the board further), and can cool the RAM at the same time as the SoC (without the need for a wider cooler base).

The PS5 also has unified memory and uses faster RAM, the RAM chips are soldered on the board around the SoC.
Yet apple is managing excellent performance with just a l1+l2.
The way I see it, you could have a Mac Pro with (let’s say) 32GB of super-fast on-package RAM and arbitrarily upgradable DIMM slots. The consequence would be that some RAM would be faster and some would be a bit slower.

They would be contiguous, not layered.
As with everything, it depends.

Buffers I believe were created for doing IO operations, wherein you need to move chunks of things around, wherein the underlying net stack needs to fill, flip, copy etc..

If you're building a video compression library with native components, then Buffers are probably going to help.

If you're living purely in Javaland memory managed space, then it's entirely another question, but know that in the vast majority of cases it won't matter.
Yes that's that main reason the article gives that a 2.3ghz laptop chip is almost as fast as a 5ghz zen3 chip with a lot more cooling.

Also, one important thing to realize is that AlphaFold was trained largely on proteins that we were able to crystallize. I'd be very curious to see how its performance fares as a function of 'ease of crystallization'.
Don't you think "M" is just for "Mac"?
No the trinity study (and its follow-ups) only run simulations for 30 years, but they did not say that the funds would run out in 30 years. To be precise: the success criteria was that the portfolio survived for 30 years, but the actual outcome was that most portfolios had more than the original principal at the 30-year mark. Which would imply indefinite survival.
That report is very enlightening, and makes clear that the IRS is not doing their job WRT high-income non-filers. However, I don't see from its numbers how you arrived at

since it only ever addresses non-filers and doesn't mention, from what I could see, percentile brackets for the filers it does discuss.
Stuff like this is a feature, not a bug. It's job creation for administrators and drug test labs, and a disincentive to apply for food stamps.
I agree with you, having a rational conversation about NN and the FCC is sometimes difficult here. It seems like people just downvote anything they simply don't agree with. Your comment is a perfectly valid observation, yet people actively try to downvote it away and silence your point of view. My gut tells me that NN is probably a mostly beneficial regulation to have in place, but I have heard some very well reasoned arguments against it that seem more substantial and less reductive than "incompetency" or "corruption".
I am still upset after all this time, at what AMD recklessly did --- out of what might be the same misguided notion as the GP comment, they made instructions like LAHF invalid and removed much of segmentation, only to be forced to put much of it back later because people were actually using them. I suspect Intel was actually working on a more consistent extension to 64 bits too, but AMD beat them to it.
"Very likely" because of what? What is your reasoning?
Apple is using high-bandwidth memory, but not High Bandwidth Memory (HBM).
Well we have well enforced laws against that which should doubtless remain unchanged. I’m saying the expectation going into a marriage should be that one partner is dominant so there are no power struggles much like a hierarchy in a company.
LPDDR4x can have multiple dies per chip.

Based on your discussion point, then I'm thinking x16 per channel, 4-dies per chip, 2-chips for a total of 8-dies for the 8-memory controllers.
You may have captured these as part of some bullet points already -
16/ Network connectivity. Make sure that the resource is accessible. It could be api server, a controller, or an application pod.

19/ Is your DNS working correctly?
20/ Does the pod have right permissions (RBAC)
Yeah overall some theme diversity. Would also be interested to know the median Elo rating by tag - since that'd serve a good sort of table-of-contents of order for people to learn chess tactics.

What is also pretty interesting would be a (fuzzed) per-tag Elo rating on the user - so they can see which themes you are good/bad at relatively (for example, if you constantly get problems on Trapped Pieces wrong your rating on those problems would be lower than your average Puzzle Rating).

Nice back of the envelope calculation. I think I'd add yield to it though.

TSMC had a 90% yield in 2019 for a 18mm2 chip[1]. Assuming a 120mm2 chip would have more defects, and assuming process improvements since 2019, maybe 80% would be an accurate-ish estimate.

Found an even better number, [2] list the defect rate as 0.11 / 100m2 => 87%.

$38/87% = $43.7

Clever, though it's worth noting that ping times circa 1812 tended to be measured in weeks or months. Mail was likely already three weeks old when delivered, urgency generally low.

That said, reading two-week-old (or older!) news often has a similar effect --- much of the urgency or uncertainty has been resolved.

Each of the languages you called out have changed dramatically to respond to the needs of users, which Bitcoin cannot, has not and will not do. You’re basically advocating for K&R C forever.

Re inflation again, has no impact on poor workers. The amount of value transferred to them in exchange for work is purely social policy and fiscal policy not monetary policy. You can improve workers mobility by supporting unions and minimum wage, not by changing the inflation characteristics of their medium of exchange they don’t get to hold on to anyways. None of your criticisms matter if you’ve invested your fiat.
The reference by Rathmanner & Hutter presents a useful analogy. It argues that Kolmogorov complexity (and Solomonoff induction) are best viewed as a conceptual gold standard, like a perfect chess computer that does an exhaustive tree search. Practical methods are approximations.

There are a few results where researchers were able to automatically infer evolutionary trees and such, by using a standard compression algorithm in place of K(x).
