03:19 this article is total BS. The reason single-core performance is important is that some tasks are just not parallelizable. When people say "single-core performance", they mean single logical core / single-thread performance. When you have a program that does not utilize multiple threads, it does not matter how many logical cores you got - you only use one, so SMT does not help here.

[@utubekullanicisi]

What he says in this video though is that the M1 feeds its body with data so well that it doesn’t need hyperthreading to fulfill its potential, and that SMT is more of a “band-aid” for situations where some parts of the chip are sitting at idle at a specific task.

Originally it stood for Acorn Risc Machines. People who are ignorant of their history will call them merely Advanced RISC Machines. People are ignorant of computer architecture will assume that the name defines their behavior today. The whole point of the risk five project was to go back to base principles. Because architectures like arm have a abandoned the base principles. Risc 5 has the hallmarks of a Risc architecture, a small clean instruction set that facilitates a efficient decode process. I've been a computer programmer since the original risc came out. This isn't history for me I lived it.

[@evtimpapushev7137]

Single-core (i.e. single-thread) performance tests aim to evaluate the ability of the CPU to run a sequence of instructions with data dependencies between them, branch prediction / recovery from misprediction; they test the effectiveness and efficiency of decoders, pipelining, Out-of-Order execution, not just pure computations. Apple's M1 has 8 decoders, but that does not magically help with resolving dependencies in the instruction pipeline, OoO execution, etc. On the contrary, there are more instructions that need to be reordered for best utilization of the pipeline; more instructions will be scrapped in case of branch misprediction, etc. On x86/64 CPUs there are only 4 decoders per thread as instructions complexity does not allow for more without making the silicon way too complex (according to Intel and AMD engineers). So, to work around this limitation, they've introduced hyper-threading and added 4 more instruction decoders. But, they cannot feed all 8 decoders from a single thread, they must process two threads. While that seems to level the playing field, it does not. Instructions from different threads are inherently independent, so the amount of analysis, reordering and planning that the CPU has to do is reduced. In the multi-threaded tests the advantages of hyper-threading are clearly visible and that's fine, that's how it should be. But changing the testing methodology just to push M1 down is utter garbage and has absolutely no merit.

[@steveseidel9967]

I believe there is a general misconception (not with you) about hyper threading (SMT). Some think this is an advanced feature that all chip designs should have. It's not. This is effectively a hack that is used to regain lost efficiency from a poor decoder (like Intel's design). This video makes it look like multiple threads on a single core will work 2x as fast. In reality, Cinebench is literally a best case example of how Intel chips can get back some efficiency through SMT and even there, it only gains about 20% performance improvement. That also comes at a cost of security as we've seen in the Spectre attacks and many enterprises actually disable this functionality because of it.

[@ThePowerLover]

_"But changing the testing methodology just to push M1 down is utter garbage and has absolutely no merit."_ *^This!*

[@bizmonkey007]

What’s counts is the M1 looks good on paper and performs well in practice. I could see changing the testing methodology if the benchmarks didn’t line up with performance, but that’s not the case.

[@childnuk]

Well done! This is the first M1 video I have seen on KZbin that refer to RISC and OOO execution. There are too many videos with very talky hosts who are doing just that, talking, nothing else! It is refreshing to see a video that touches lightly but does reach the core advanced concepts within CPU designs.

[@almostinfamous42]

That buff vs buffer was absolutely hilarious 😂

[@MegaAbzzzzz]

About the Cinebench benchmark, Intel 8 core 16 threads, or course it wins because realistically M1 has a little big config. Yes it is 8 core but only 4 of its cores CPU are high performance based cores, and 4 low power cores. That said this is crazy impressive what it has been able to achieve with what its got.

[@YuFanLou]

This video is embarrassingly disappointing coming from Engadget. The cited WCCFTech article misleads its readers as well as the video author into misunderstanding of modern CPU architecture and performance benchmarking. We have always benchmarked single-thread and multi-thread performance; there is no basis whatsoever to measure “single-core” performance with 2 threads, since for software developers using 2 threads versus more takes a similar amount of additional effort and care not required by single-thread. Unfortunately from the comments, many more people are being misled by this video. This is the most dangerous form of misinformation: a bit of truth, like reordering, but presented with a false methodology. I’d rather watch more of the interview with the RISCV CTO for his experience and wisdom.

[@tjhrulz]

This. Also the snippets we got from Mark even alluded to some of the issues with this reporting. SMT is essentially a hardware hack that is used to try to squeeze extra performance out of certain multi-threaded workloads, although as Mark alluded to not all multi-threaded workloads gain from it (although I will say it has gotten better over the years). I'm not going to trash talk the video to badly, SMT in the early days could sometimes hurt a single-threaded workload (although toggling it off and on on a modern CPU doing a single threaded cinebench score the variance in your results would likely be within margin of error), also many modern x86 chips go after a highly threaded chip as opposed to squeezing an extra few megahertz so it is definitely fair to say that you need to compare both single-threaded and multi-threaded workload scores. It's just it clearly needed someone with an architecture background to actually help with the writing and fact check the video.

[@godkingmonkey20]

One of the main reasons that the M1 can do things slightly faster is that it's a reduced instruction set computer processor. Even if a processor is multithreaded a single thread process is still only a single-threaded process.

[@bakedbeings]

I'm probably confused, but the problem he's describing with underused resources (alu, fpu) sounds like what pipelining is designed to solve, not hardware multithreading (hyper threading) on a single core. From what I understand HT is designed to reduce the amount of clearing and repopulating of caches and registers when switching threads/contexts. Multithreading most often doesn't have much to do with keeping parts of the core busy: it's attending to work that isn't tied to procedural execution, and using many cores because a) because it suits the problem and b) we're not getting the sort of gains we used to in clocks while bleeding power as node size falls. Have a look at the power wall issue for more insight (maybe it's even been discussed on this channel?) 👍

[@g2h0]

this is the best vid on the m1 that ive been able to find

[@JensHeuschkel]

I think there is something mixed up. RISC processors, in general, are not designed to execute an instruction in one cycle, by any means. Typical ARM processors in our phones are multi stage processors, meaning they execute a stage in one cycle but a instruciton has to pass all the stages the processor has. This is mainly done to improve the clockspeed of the processor and is common practice for nearly every processor design. Anyhow ... compared to CISC instruction, a RISC instruction is way faster (which should be sufficient to support your point)!

[@mohibeyki]

The point of single-core benchmarks is not to measure how fast a single core is, it is to see how fast a single thread (in your application) can be. It used to be very useful when most applications were not multi-threaded (some still are not). So yea, while I agree with the fact that you are not comparing each of those AMD/Intel cores to one M1 core, you are measuring how fast your computer is if the application you are running is single-threaded.

[@philsarcade]

As you mentioned in the video, I'm really interested in how they push that amount of graphic power in a non fan Air and still consume so little battery power. What is their secret sauce and is it scaleable?

[@groszak1]

Planned obsolescence.

[@brightboxstudio]

Part of the answer is that Apple spent 10 years figuring out how to create high graphics performance in their A-series SoCs for iPhone and iPad, which have very limited cooling and power. Once Apple mastered that, they were ready to move that chip design to desktop/laptop devices, where it can do the work on much less power, which results in much less cooling needed. And leaving a lot of power/thermal headroom to crank it up. In contrast, x86 designers spent the same years assuming everyone had lots of power and active cooling, so now it’s a challenge for them to design an SoC with high performance at the low wattage/heat of the M1.

[@steakman7662]

Wide and slow design and super dense process node (TSMC N5).

[@AlejandroLZuvic]

They’re using tile based deferred rendering, which in reality is and always was more intrinsically efficient than immediate rendering. Sadly, as he mentioned in the video, there are very few details on how the GPU hardware is actually designed and implemented. Let’s hope somebody could reverse engineer how it works.

[@philsarcade]

@@AlejandroLZuvic This is what I'm saying. There is very little out there but someone knows or can examine the chip die and have a general idea of the processes involved. When you look at the like of Invidia and the likes, they are very fast, but seriously power hungry. Will be interesting how Apple scales their design and if they can keep that thermal envelope low.

[@imabot7495]

You missed one important thing, the branch predictor in the apple architecture, it way more advance than anyone else and reduces latency as well.

[@asdf1616]

The presenter confuses SMT (Single core Multiple Thread) with multithreading. Multithreading is running more than one thread in a CPU, whereas SMT (or hyperthreading as Intel calls it) means running two (or more in some cases) threads on a single core. Both Intel and Apple silicon chips do multithreading, but Apple doesn't do SMT. The reason Intel (and AMD) do SMT is that since they use a CISC instruction set, each instruction does more, so it takes a significant amount of time to decode each instruction, so the figured they could use that time to execute other instruction. RISC architectures such as the M1 don't need to do this since they use smaller and faster to decode instructions.

[@RaGa_BABA]

This is the best video I have seen so far about m1 unlike other crappy youtubers.subscribed.

[@JustinZymbaluk]

The thing to keep in mind here is that even when the advantage “evaporated” you’re comparing M1 which is the lowest end and worst apple silicon chip we will ever see to some of the highest end x86 processors available. The M1 still punches way above its weight class

[@sidbrun_]

Yeah this is pretty important. So far the M1 has just been put in their lowest tier laptops, so really people shouldn’t necessarily expect high performance because the laptops they put them in aren’t meant to be high performance anyway. The bar has been moved, the maximum has become the new minimum.

[@Teluric2]

What advantage? M1 is a 5nm chip vs 14 or 10nm intel chips.

[@mikemojica]

Advised my mother to wait for Apple to release the m1 laptops before buying. So when she finally bought the m1 air, I installed civ 6 and put all the settings to max and it ran without any issues. Not the most impressive game for benchmarking but since I don’t really play games and only occasionally play civ 6 when I do play games, it blew my mind.

[@youngwt1]

I always thought running multiple threads on one core was called HyperThreading (intel) or SMT (AMD)? For intel at least that was usually a value added feature for the i7 line

[@steakman7662]

SMT is the technical term, "hyperthreading" is intel's marketing term. Just like AMD calls their L2+3 cache "gamecache" when it's really just regular cache.

[@TechTechPotato]

SMT isn't a band-aid either. Cores are designed with SMT in mind, and you make very important design decisions based on that idea. To suggest it's a band aid would mean that you don't consider SMT at the start and add it later. It's very much NOT the case.
