@@rusticraver82 Oh sherlock!

Does RISC really mean anything anymore? I think the Arm architecture has some major advantages don't get me wrong but adding new instructions to a CPU over many generations eventually starts to get you well past the definition of Reduced Instruction Set Computing.

Was true in the 90s, it's even more true in this multithreaded and asynchronous computing world.

Cerebras has an 850,000 core chip, so theres that.

Unless MS cleans up their act in regards to updates, then it will be Unix or Linux laptops. Well... It is already in Unix laptops in the form of M1.

linux is more recommended with arm and risc, since its the first to support it from a timeline standpoint, plus x86 and x64 emulation is shit on windows and its great in linux even without a dedicated translation engine

I think everyone can see where this is going, personally I think you'll probably see a hybrid era soon, as we transition all the x86 architecture towards risc

@@xxportalxx. I doubt that there will be a hybrid era. There might be an emulation era just like how apples doing it with m1. I still had to ask because AMD and Intel haven't shared arm related news in their Roadmaps. AMD is also still capable of competing with the m1.

Zen 4 Epyc is rumored to be 96 cores and 40% performance uplift per core compared to Zen 3 Epyc. So no, x86 is not going anywhere. In fact, AMD's market share in the server market is increasing faster than ARM's market share in the segment.

@@1idd0kun I know and I agree but the thing is x86 is very much a mature platform and arm entered this market recently and it's already competing. Also for servers, the efficiency benefits can be huge. They have massive cooling and power costs with redundant power supplies. If arm chips can manage near-level performance with much higher efficiency then it makes sense to move to arm.

@@parthmalani6286 The efficiency benefits isn't as significant as people make it out to be. For example, the Amper Altra ARM CPU has 80 cores and a TDP of 250w. The current AMD Epyc 7763 has 64 cores and a TDP of 280w. The Epyc has 12% higher power consumption, but also offers better performance than the Altra in almost all benchmarks.

Yes, the common server chips from Intel and AMD.

That's actually a good question. If the design is monolithic I would expect yields to be on the low side.

Ask Cerebras with their single wafer 850,000 core chip.if its possible.

Yields aren't just a binary, you will get overperforming and underperforming cores around the spec, usually averaging towards that spec. And OS process schedulers even if they don't have some kind of accounting for relative clockspeed and cache usage will to some degree naturally favour the over-performing cores because they'll take less time to finish their instructions.

@@markhaus When the chip is so big there's gonna be lots of defects, with many being enough to actually make some cores inoperative, not just underperforming. Besides, this chip doesn't have dynamic boost. It's meant to work at the same frequency across all its cores. So if even a single core can't get to the target frequency, they would have to throw the chip away. That's why for such large chips, a chiplet approach is better than monolithic. Every chiplet is tiny which reduce defects/increase yield.

@@markhaus I am not too familiar with the fabrication and its related processes so do correct me if I'm wrong in my understanding. What I was wondering was what @1idd0kun mentioned in another reply. Defects during fabrication can lead to some cores being totally inoperational. So if you are trying to pack 128 cores into a single package as a monolithic IC, isn't there a higher chance of some cores just not working due to the defects during manufacturing? Hence in turn the lower yield of a true 128 core processor? But I think I get what you meant too. Isn't that what both Intel and AMD do to their consumer CPU lineup? The best performing ICs from a single wafer are packaged into the i9s and R9s. The other ICs in the wafer that are not fully up to the spec get some cores disabled and then is shipped as the lower end variants such as i3s,i5s etc.

Yes, and more with SVE2.

@@jobayedhossainbadhan3474 yess..buy old one with full support

I didn't know about that, I will need to look it up. 👍 Of course the difference here is that these CPUs have the performance needed to be successful.

@@GaryExplains well I certainly hope the performance is there! 20 years ago, when I was looking at alternatives for customers who just had to have a physical machine of their own, most colocation facilities were ill-prepared to supply so much power or cooling per rack. Back then the servers being run were not that compute-intensive. Today we need something that can match the performance of a dual EPYC machine but use less power.

the old software is the reason, its the same reason desktop linux isn't more popular :p

The reason is nobody has made a competitively priced range of high performance desktop processors. Most Arm desktop systems are crazy expensive. That is why the new Mac's as so amazing. I have several videos about this very subject here on my channel.

@@GaryExplains why doesn't qualcomm launch a beefed up SD 888+ for laptops? Like 2 cortex X1 cores and 4 cortex A78s with higher clocks and TDP? Sure, it won't beat the M1 but it's much more efficient and powerful than x86 laptop chips, right?

@@DrAdityaReddy It will.

also risc v is going to be a thing very soon

@@jimitsoni18 it already was, it was called Itanium, it flopped.

@AstroCat sure thing. Thanks

Because the border has faded between risc and cisc. Middle ground is the key to efficiency and performance.

For sure

Rumors says that Apple M2 will use ARMv9 license also so they can make pro computers that can handle bigger computations for scientists.

@@nocivolive I think not sure need to confirm it but the Firestorm Cores in the M1 have better IPC (instructions per cycle) and PPC (Performance Per Clock) than even what is projected by ARM for their Makalu and Matterhorn Cores. If Apple made a Chip with 128 of them it would destroy everything else except what Nuvia had planned with Phoenix.

@@EnochGitongaKimathi I don't think ARM gave out details about the makalu and matterhorn cores

@@DrAdityaReddy Arm haven't given much details about the next generation of CPUs but they did release slides showing their roadmap of the projected CPU peak performance.

Yep, the Nokia 3310 used the Texas Instruments MAD2WD1 (based on ARM7TDMI).

@@GaryExplains Cool. Thanks. I learned something new today. 👍👍🤘

I don’t think normal consumers would need a 128 core processor. It’s also a lot better than using x86 in terms of power/heat.

That is the point, it isn't hot and power hungry. 🤦‍♂️

Ermmm, no.

Avoid writing into memory shared between cores, the cache updates are expensive as f**k, and you're fine. If you insist on writing a fancy lock-free queue where any random thread can pick up work consider something else. Synchronization means accessing memory, reading is cheap but writing is slow as it locks the bus and everyone is just waiting and not doing anything useful if they read from a cache line that has been dirtied by some other core. If you can find a way to run the threads in isolation, no sync problems, no slow-downs. I/O might still be a bottleneck, you need to get data to crunch.. not everything is pure maths.. 128 cores might be a bit demanding on the other areas to realise the full potential..

Oh, and when you try to do some clever work-balancing stuff, the communication indeed is due to memory and that again causes problems.. then if you don't do any balancing it may end up being "wasteful", so it's a kind of a problem that fucks you up from both ends.. but these are mostly single-process-multiple-thread kind of issues, for tasks that don't depend on each other things scale pretty linearly.. overall it's a step into the right direction but at some point just throwing more cores at the problem will bring out bottlenecks that need to be resolved.. 128 threads is an awful lot, the waste begins to show up at around 30-40 threads if you don't think about what you're doing..

Certainly, you need more careful programming to take advantage of a highly parallelised processor. Maybe they provide options for ultraparallel processing like wavefront options or things like in compute shaders

LOL... You will have a long time to wait.

@@GaryExplains and that right there is the problem with this channel. ARM has been around for 35 years while RISC-V moved from a university project to an open source foundation less than six years ago. The first ever buyable RISC-V hardware (HiFive1) came out 4.5 years ago running at 320 MHz. The Pi 3 has been out since Feb 2016, the better BeagleV StarLight is in the hands of developers as a beta test version right now and will be in mass production later in the year. Sipeed and Pine64 will have very attractive competitors for the Pi Zero with the Allwinner D1 SoC later this year -- again, some developers already have the production SoC in their hands on eval boards. Alibaba and SiFIve have cores comparable to the A72 in the Pi 4 announced 18 months ago and probably available in actual SoCs within the next 12 months. That's probably going to be about about three years after the Pi 4. RISC-V is behind, no doubt, but catching quite quickly. ARM has made some advances since A72 but they are only incremental. That Allwinner D1, by the way, has an early version of the RISC-V Vector ISA. I'm not aware of any ARM SoCs with SVE available to the general public.

No, it isn't.

98. - Blasphemy would be common (2 Timothy 3:2; Revelation 16:9, 11, 21). Consider how often people use their Creator's name (God, Lord, or Jesus Christ) as a curse word. What they have done is liken the One who is the source of every blessing (eyesight, sunsets, food, family, friends, etc.) to a four-letter curse word. Fifty years ago, Hollywood seldom used God's name in vain. Today, nearly every movie includes blasphemy. 99. - Sexual immorality would be rampant (Jude 18; Revelation 9:21). Keep in mind, Jesus said whoever looks to lust has already committed adultery in his heart (Matthew 5:28). Therefore, God equates Internet porn, lustful movies, TV shows, and magazines to fornication. The availability and consumption of sensual products has exploded in our generation. 100. - Men would sear their conscience so they could continue in sin (1 Timothy 4:2). The conscience is where God reveals right and wrong. Con means with and science means knowledge. Therefore we sin with knowledge when we ignore God's moral law and violate our own conscience. 101. - Men would mock the warning signs of the end of the age saying, these signs have always been around (2 Peter 3:3-4). The Bible even reveals their motivation - they love lust. There are many more last days prophecies (several too detailed for this brief list). However these 101 demonstrate that the Bible is the inspired Word of God. It is true that some of these signs have been around for millennia, but only our generation has witnessed the coming together of every one of these events. Contrast the Bible's 100% track record with other self-proclaimed prophetic sources and there is no comparison. The false prophets typically repackage and plagiarize the Bible's prophecies for the unsuspecting masses, or they make so many vague prophecies that one is bound to be fulfilled. Nostradamus did both. Jesus also said that some men would be gripped with fear when these signs occur (Luke 21:26), while others would look up with hopeful expectation (Luke 21:28). Which camp do you fall into? If you're fearful, there is good news and bad news. The bad news is that God will judge every man who breaks even one of His laws. Have you ever blasphemed your Creator's name, Lied (white lies and fibs count)? Stolen (cheating on a test or taxes is stealing)? Looked with lust? If you have answered yes to these questions, then by your own admission, you are a blaspheming, lying, thieving, adulterer at heart. And we have only looked at four of the Ten Commandments (Exodus 20)

Considering that the Pi 4 uses a 5 year old CPU cores design, then I wouldn't expect Armv9 in the Pi for several years.

@@GaryExplains 5 years old now, yes. But RPi4's release was 2 years ago. Incidentally, it was 3 years between A72 standardization and BCM2711's release. Then only another few months to the RPi4 release. If this pace is kept, we're looking at about another 3 years for an ARMv9 RPi. And I have to be honest (and Christopher "Explaining Computers" Barnatt would likely agree), these SBCs are the only way the average user can develop for ARM. Accessibility, I think, is the key to ARM's future. A large, well-funded organization might, but no one person wants to drop several thousand on an ARM server when an ARM SBC can be had in the sub-100 USD, CAD, EUR, or GBP price point (or its equivalent in local currency).
