I believe they also have a jump port for exactly that purpose. If that doesn't work you are stuffed though, as I believe has happened to some cyber truck owners.

When the car isn't driving I believe the main battery isn't connected for safety reasons. It's a high voltage battery, and having it connected all the time even when the car is being serviced is an unnecessary safety risk.

Yeah they could and probably should use a different battery technology than lead acid. Preferably something with a wide temperature range. Lithium Titanate Oxide anyone?

They do have a manual way of opening the car door if memory serves. It's just in a hard to find place where a toddler wouldn't think to look. Either way it's a bad design. Nothing wrong with manual door handles imo.

My bad

Wayland isn't actually a piece of software though. It's a protocol. This isn't like X11.

But generally speaking, ARM pushes for going wide, and X86 pushes for more IPC on fewer cores (pipelining, out of order execution, etc).

Going wide also means having more superscalar units and therefore getting better IPC. You also don't really understand what pipelining does. Using pipeling increases IPC versus not pipe-lining sure, but adding more stages actually can reduce IPC as with the Pentium 4. This is because it increases the penalty for misprediction and branching. Excessive pipeline stages in a time before modern branch predictors is what made the pentium 4 suck. The reason to add more stages is to increase clockspeed (pentium 4) or to bring in more complicated instructions. The way you talk about this stuff tells me you don't actually understand what's going on or why.

Also x86 has had memory controllers on CPUs for well over a decade now. Likewise PCIe, USB, and various other things have also been moved to the CPU - north-bridges don't even exist anymore. Some even integrate the southbridge too to make an SoC much like a smartphone. None of this is actually relevant to the architecture though, they are entirely down to form factor, engineering decisions, and changes in technology which are relevant to the specific chip or product. If x86 had succeeded more in smartphones and ARM had taken the desktop (as was there original intention) then you would be stood here talking about x86 chips including more functions and ARM chips having separate chipsets. So this isn't a fair thing to use to compare x86 and ARM.

It's also not really true that x86 has fewer cores. A modern Ryzen in even a laptop form factor can have up to 16. That's more than Apple put in their mobile chips. I get why people think this way. It's because phones had 8 cores long before PCs, and because it made sense at the time. When ARM cores were smaller and narrower and had much less per-core performance and IPC increasing their number made sense. Likewise more smaller cores is more energy efficient than fewer bigger cores, and this makes sense for something like a smartphone. However nowadays when big, wide, power hungry ARM cores exist and are used in higher power form factors than a smartphone there isn't really the need to have so many. At the same time x86 have efficient small cores these days that in some cases get better performance per watt than their ARM equivalents, and x86 core count has skyrocketed. Both of these platforms were originally focused on per core performance too, as multi-core consumer devices simply weren't a thing. All of this "ARM has more cores and x86 has more single core performance" malarkey was only true for a certain window of time. It wasn't where this all started and it's not where we are going now. Instead what we are seeing is convergent design where ARM and X86 are being used in the same use cases, using the same design concepts, and maybe eventually one will replace the other. Only time will tell.

If you were comparing x86 vs RISC-V you might not be far off. But with ARM vs x86 they have basically the same use cases. Namely desktops, laptops, servers, networking equipment, game consoles, set top boxes, and so on. x86 even used to be used in mobile phones or even as a microcontroller. It's not used in those applications as much now obviously, but it's very much possible. Originally ARM was developed for the desktop too, and was designed for high performance. Lookup the Acorn Archimedes. When people say ARM is coming to the desktop they really should be saying ARM is coming back to the desktop, since that's where it started from.

You're also not correct on the clock speed and IPC front. For a long time Apple's ARM implementation had better IPC than x86 chips. The whole point of RISC is that you can get better clock speeds and execute more instructions vs CISC having more complex instructions being executed more slowly. The only really correct part is that x86 chips are more pipelined. This is due to them being CISC essentially and needing more stages to hit the same clockspeed. Apple's ARM makes up for this by having more superscalar units than x86 chips, allowing for greater IPC.

Putting graphics and video compression stuff on x86 chips isn't new either. That's a question of system design, not of x86 vs ARM. In the server market you get ARM chips that are CPU only. Both also come paired with FPGAs. So it's not even fair to say ARM has more accelerators on chip. Also any ARM chip with PCIe (such as the server ones) can take advantage of the same co-processors that x86 can, the only limitations being drivers and software.

Since when did AMD make ARM chips? Also they aren't as different as a motorcycle and a car. It's more like compression ignition vs spark ignition. They are largely used in the same applications (or might be in the future), although some specific use cases work better with one or the other. Much like how cars can use either petrol or diesel, but say a large ship is better to use compression ignition and a motorcycle to use spark ignition.

areyouevenreal , 17 days ago to Technology in The Framework Laptop 13 is about to become one of the world’s first RISC-V laptops

Except modern ARM chips are actually CISC too. Also microcode isn't strictly RISC either. It's a lot more complex than you are thinking.

There are some RISC characteristics ARM has kept like load-store architecture and fixed width instructions. However it's actually more complex in terms of capabilities and instructions than pretty much all earlier CISC systems, as early CISC systems did not have vector units and instructions for example.

areyouevenreal , 17 days ago to Technology in The Framework Laptop 13 is about to become one of the world’s first RISC-V laptops

ARM is load-store and has a relaxed ordering. Whereas x86 has instructions that can read straight from memory, and has Total Store Ordering. ARM also is fixed instruction width, where x86/AMD64 is variable instruction width.
Outside of that the difference is mostly licensing.

areyouevenreal , 17 days ago to Technology in The Framework Laptop 13 is about to become one of the world’s first RISC-V laptops

The CISC vs RISC thing is dead. Also modern ARM ISAs aren't even RISC anymore even if that's what they started out as. People have no idea what's going on with modern technology.

X86 can actually be quite low power (see LPE cores and Intel Atom). The producers of x86 don't specialize in that though, unlike a lot of RISC-V and ARM producers. It's not that it's impossible, just that it isn't typically done that way.

areyouevenreal , 17 days ago to Technology in The Framework Laptop 13 is about to become one of the world’s first RISC-V laptops

It's not just a separate product line. It's a different architecture. Not made by the same companies either, so ARM aren't involved at all. It's actually a competitor to ARM64.

This sounds kinda rapey

No I haven't forgotten anything you have said. You were claiming that good cops weren't being pushed out of the USA police, and that they aren't all bad as a result. Yet you haven't actually given a single example.

Don't worry. Although you appear confused and defensive about these statements, nobody is saying otherwise.

You are the one being defensive and confused here. We weren't arguing that only some are bad. I am arguing that the majority are bad in the USA and Mexico because any good police would be pushed to leave because of institutional failings.

areyouevenreal , 18 days ago to Lefty Memes in ACAB.

Logically explaining the truth and repeating basic facts?

What facts? You keep making statements without baking them up at all, or even giving any reasoning.

I don't agree with leftists that all police throughout the world are evil or unnecessary. I think in some countries they are demonstrably better or worse than others. Places like Mexico and the USA they seem to be corrupt or straight up sadists, who are in the pockets of gangs and rich capitalists respectively.
