I went into this video hoping to learn more about how CPU architecture looks at a microscopic level and what an ALU looks like and how it functions.

Intel chips or x86 moves the complexity to the chip itself(more instructions). so it consumes more energy M1 or ARM-based architectures is based on reduced instructions (RISC). It moves the complexity to the software(you have less and basic instructions to play with) so it takes larger size on memory but it's more efficient. it can be faster or slower than x86 depends on the design and optimization

Most knowledgeable people will say CISC is more specialty instructions that take more clock cycles and RISC simpler instructions that make longer code, but this is not nearly as accurate as it used to be. The M1 is a great example if a RISC architecture that has many specialty components and commands that we would traditionally consider the domain of CISC architecture It’s still useful to mention the traditional differences between the two, but I think these differences are becoming less and less accurate as time passes.

Anyway it has circa 4500 transistors. The pretty grid pattern at top is the Instruction Decoder, clock is above it at the far right end of that grid, and the ALU is in the lower half just to the left of centre (along with shift registers and other things). That chip was used in the original Apple I and Apple II desktops that Woz designed which gave Apple its starting products. You can see the individual transistors on its die with a 180x optical scope.

I primarily dev in Android Studio and I had to get an M1 because of the benefits while waiting for a better SoC on a larger MBP or smaller mini… but I changed a few settings; mainly memory heap and editor refresh rate, and it runs smooth as butter now. Plus they added ARM AVD support now and they run pretty well, emulating an ARM device on an ARM SoC. I will agree it’s not ideal, but I keep myself to one project open at a time and can barely notice a difference at this point. If they release a silicone native AS build it should be at least as good as the performance of my older intel MBP workhorse. Luckily Apple devices make it easy to share, drop off and pick up work between devices. So I can easily hop over to my intel machine if need be, but I haven’t used it for Android development since getting my M1. After seeing WWDC I think instead of trading in my M1 and some cash for a new MBP M1X, Ill just buy an additional mini M1X at the same specs and sell my older 15” MBP. I think eventually everything will be, or have an ARM build available.

This is a very nice collaboration. Thanks guys :)

JS and Py actually compile into bytecode, which is executed by their respective interpreters. The interpreter, though, is the one running on machine code. Also, the execution phase is more complex than that; there are all kinds of opcode extensions, prefix bytes, addressing modes, immediate values, etc., etc. But an important note is that the operand (which isn't even always there, like with RET, or of which there are multiple, like with IDIV) doesn't always reference memory-it can also reference CPU registers (?ax, ?bx, ..., and r8 through r15 in 64-bit operating mode) in the register-only addressing mode. In addition to those, there are also some special registers that allow the CPU to function; such as ?BP (base pointer) ?IP (instruction pointer) FLAGS (CPU state flags), and so on. * The question marks indicate a register size. E = 32 bits and R = 64 bits. For 16 bits, take out the question mark. For 8 bits, use l and h for low and high. AL -> low 8 bits of accumulator BH -> high 8 bits of base CX -> 16-bit counter EDX -> 32-bit data RIP** -> 64-bit inst. pointer ** Not available to instructions Oops, I'm rambling again. I'll see myself out. Edit 0: I've seen myself back in to correct the r range. r0-r7 actually refer to the previously-mentioned registers. (Source: stackoverflow.com/a/9130707 )

While M1 is amazing in its own right, it can’t break how physics works. Lot of stuff that’s running faster on the M1 is because it’s specially coded to utilize fixed function asic or the JIT reconciler/emulation of Rosetta can sometimes skip a lot of steps which isn’t great for mission critical work if need an error free environment. But most Rosetta emulated apps run slower still. Also, Lot of apps don’t utilize fixed function asic on intel or AMD for some reason, been a issue for a long time and nothing magical just because see it happening on M1. People look at premier for the best example of how much faster M1 is vs intel, the reality is by default premier disables intel QSV optimizations on windows and on Mac it’s just not available for some..reason? Turn those QSV functions on in premier on windows and if you have a recent intel CPU the M1 isn’t that far ahead if at all. Another aspect is synthetic benchmarks, Comparing what they believe to be “raw” performance. In reality, most of these benchmarks are very small and can easily fit within the cache operations without much eviction of code to DRAM, and thus get a huge boost in performance. This is also why we are seeing in same benchmarks, a lot of zen based chips running rings at the top too.. none of this specifically invalidates the benchmark, but it’s not a true raw compute scenarios in my book. Take geek-bench for example, it can run each test with minimal code eviction. Cinebench R20-R23 is the same way, this is why memory speed plays less role in this “CPU benchmark” and can even go single channel on my platforms and score similar or higher on some platforms. This because each tile tries to work within the cache. The M1 has a fairly large chunk of cache that’s unified between cores, it also acts as a buffer to DRAM, allowing the M1 to hit the DRAM less often.

Isn't a big part in the performance of the M1 the reduced (ARM) instruction set? Or does it really just come down to the M1 being a SoC?

Its quite frustrating in itself, and looking at Alexander's overview it would've been very bad if all my workflows just broke because of M1. Sure its not the best, performant machine and I do feel jealous sometimes. But atleast I can "just work", and be assured that my current device will be the last to lose support before the M1 lineup becomes the only lineup. Thank you again!

One of the major drawbacks of SOC, is that chips cannot be repaired but only replaced. So the overall cost to get back normal would be very high (for the company/user), considering the number of components it has fabricated on it.

The advantage is obviously the power consumption, and that might lead people to think it's more e ological to do it like this, but here comes the drawback... The less stuff you can upgrade in your computer, the less it's gonna serve you, eventually leading to uprise in throwing out new stuff just to buy new, whereas modular machines sometimes just need more memory or an expansion card and there thry go serve for another one or two years.

Best explanation on the differences with general CPU.

I think you meant opcode, not optcode 😉🤓 Nice video!

What *really* makes M1 faster is that decoding an ARM instruction is much simpler than decoding an x86 instruction. For example, each x86 or AMD64 instructions have different number of bytes. Some of them are 4 bytes, some of them are 6, 8, or even 12, etc... On the other hand, ARM always has fixed length. I don't know about 64-bit ARM, but I do know that 32-bit ARM always use 4-byte(32-bit) per instruction(which includes both opcode and operands). What this means is that it is very easy to predict where to fetch next instruction from, which allows decoding more and more instructions at the same time. Then when an instruction finishes, everything needed to execute next instruction would be immediately ready. Also not to mention that ARM, which is RISC(Reduced Instruction Set Computing) architecture, has far fewer instructions than x86. So instruction decoder itself would be also a lot simpler.

I'd be totally down to buy an M1 laptop! Just have to wipe the drive and install a dual boot with a Linux installation and windows 10... You'll never catch me bending over backwards trying to conform to Mac OS. Prefer it if I could get it in a different case as well..? Then again Apple is afraid of change so I guess I'd be stuck with the 13 year old design.

CUTTING EDE 13 year old design!

This is a really good video !

Best Explanation Ever 👍

Can we get an awesome video (which is any video on this channel) about WebGL ?

Its funny listen a *web* developer talking about cpu architecture, when literally none of their work relay directly on any of this stuff.

It's even funnier that the comparison is made on intel mac and m1 mac and not windows intel/amd + linux intel/amd + intel mac + m1 mac...

This is the first Beyond 100 Seconds which doesn't throw me offbeat with Jeffs style!

Finally someone who explains well the differences!

Intel and AMD are building chips on the basically ancient x86 architecture. It basically means compared to what would be possible today they take a performance penalty as a tradeoff for backwards compatability. Otherwise with every new cpu you buy youd need to rebuy your entire software collection from scratch or run different virtual machine setups one way or another. For Apple which actively fight against everything good for the consumer (even in court) this is not an issue since their software isnt compatible with anything else anyways. The M1 chip was at the time of its introduction also the only cpu for those applications build on TSMCs cutting edge 5nm process which in this video was compared at best to a cpu build on Intels 10nm process. Current mobile chips from Intel released a few months after this video basedon the alderlake architecture are also outperforming the M1 chips again in most cases. The modularity of todays PCs which was by some ironic plottwist portrayed as something negative in this video has indeed the rather small disadvantage of using more power than an SOC. But it comes with the huge and obvious advantage of being able to replace just a broken part instead of the entire machine. Of course also the ability to individually upgrade parts. Apple on the other hand is again fighting actively against the customers option to repair or replace parts on their products with deliberate design choices and also in court. Its the scummiest of tech companies trying to strip us of every last penny with their policies. And this video sounds like a commercial for them. I wouldnt be surprised if this was paid for. But Apple is also known to have religious zealots like this preaching to the masses. Weird cult-techcompany hybrid.

That was the longest 100 seconds of my life.

0:54 rare typo.... thanks for another great video. Fabulous channel

This was extremely interesting!!!
