ARM
 
Poštovane kolegice i poštovani kolege,

otvaram ovaj thread da rasprava vezana za ARM procesore bude objedinjena na jednom mjestu. Sada imamo par slučajeva gdje se rasprava odvija pod drugim threadovima koji su totalno nevezani uz procesore (tipa http://forum.pcekspert.com/showthrea...=306533&page=2) pa molim da se sve diskusije prebace ovdje. Ukoliko će rasprava biti kvalitetna i obilna, admin će kreirati novi topic kao što imamo za Intel i AMD.

Da započnem raspravu, našao sam ovaj članak iz 02.10.2012.

https://www.wired.com/2012/02/how-wi...n-arm-tablets/

Zanimljivo da su Windows RT ugašeni makar se cijeli projekt ponaša kao prasac na kolinju, mlatara nogama a nikako da odapne:

https://www.howtogeek.com/116637/htg...it-mean-to-me/

https://en.wikipedia.org/wiki/Windows_RT

Ovo spominjem kao nastavak na diskusiju oko budućnosti ARM-a, mišljenja sam da nije da će Microsoft pustiti ARM bez podrške. Možda jednog dana bude došao na istu ideju kao i Apple, jedan ekosustav za sve aplikacije. Svojedobno je to i bilo aktualno i Microsoft je to planirao dok su još Windows Mobile bili živi (pa su im se ljudi razbježali), iste aplikacije na bilo kojoj platformi - desktop, laptop, tablet, smartphone. Možda se opet dosjete toga što su se već jednom dosjetili...

Appleov M1 u praksi, ima nešto benchmarka za usporedbu:

https://www.pcmag.com/reviews/apple-...i-m1-late-2020

Računajte da nisu sve aplikacije optimizirane za ARM tako da tu ima još mjesta za poboljšanja. Uglavnom, svi hvale M1 kao hladan chip(set) s nižom potrošnjom u odnosu na dosadašnja procesorska rješenja.

Bio sam skeptičan u početku, ali mislim da nije pretjerano prognozirati skoru smrt x86, barem kad je o notebooku riječ. Mislim, za 99% korisnika nije bitno niti ih uopće zanima da li je unutra x86, arm, cisc, risc ili powerPC :D ali kad vide da ovo čudo drži bateriju 16 sati, teško će nakon toga pristati na i7 koji je pojede u 6-7. Razlika je jednostavno ogromna.

Nije badava Apple najavio da će isti procesor biti u cijeloj liniji proizvoda, od iPhonea i iPada pa do desktopa. Još će najbolje biti kada će se iste aplikacije izvoditi na bilo kojem uređaju.
Spomenuo sam u jednom drugom threadu da je Microsoft istu zamisao imao dok su Windows Mobile bili živi pa su odustali paralelno s gašenjem te mobilne platforme. Sad vjerojatno lupaju glavom u zid.

"Because one core is able to make use of almost the whole memory bandwidth, having multiple cores access things at the same time don’t actually increase the system bandwidth, but actually due to congestion lower the effective achieved aggregate bandwidth. Nevertheless, this 59GB/s peak bandwidth of one core is essentially also the speed at which memory copies happen, no matter the amount of active cores in the system, again, a great feat for Apple."

Zbog ovog je nešto sporiji pristup memoriji u testovima gdje se mjeri u nanosekundama, makar koliko vidim po benchmarcima to ne radi nikakvu smetnju, kao što je i navedeno u pasusu. Ali, jednog dana kada izađe M2 i bude riješen pristup memoriji na drugačiji/bolji način, mislim da će se i AMD i Intel pitati čija mama crnu vunu prede. :D

Intel responds to Apple’s M1 chips with cherry-picked benchmarks:goood:
Citiraj:
In benchmarks published by Tom’s Hardware, Intel compares its 11th Gen Core i7 processor with the M1 CPU found in the latest MacBook Pro. Intel claims its latest chips beat Apple’s M1 performance by 30 percent in overall Chrome browsing tasks, and every one of its carefully selected Office 365 tasks. This range of benchmarks are clearly cherry picked to favor Intel’s chips, especially as some make use of Intel’s hardware acceleration. Most of the tests aren’t industry standard benchmarks, and Intel even swapped out the MacBook Pro it was testing with a MacBook Air specifically for the battery life tests. Reviewers have regularly found the MacBook Pro battery life to be superior to the MacBook Air and similar Windows laptops, but Intel used the Air for its comparisons to show it only beat PCs by six minutes. Intel is clearly concerned by Apple’s first chips, and we’re now waiting for the company to respond with its own processors instead of benchmarks. The entire PC industry will need to respond to Apple, at a time when laptop sales are growing. Intel’s new CEO, Pat Gelsinger, looks set to battle Apple’s M1 chips in the years ahead, and he’s already made it clear that Intel has to beat Apple in the future.

ARM takes aim at Intel chips in biggest tech overhaul in decade:kafa:
Citiraj:
Arm Ltd. unveiled the biggest overhaul of its technology in almost a decade, with new designs targeting markets currently dominated by Intel Corp., the world’s largest chipmaker. The Cambridge, U.K.-based company is adding capabilities to help chips handle machine learning, a powerful type of artificial intelligence software. Extra security features will lock down data and computer code more. The new blueprints should also deliver 30% performance increases over the next two generations of processors for mobile devices and data center servers, said Arm, which is being acquired by nVidia Corp. The upgrades are needed to support the spread of computing beyond phones, PCs and servers. Thousands of devices and appliances are being connected to the internet and gaining new capabilities through the addition of more chips and AI-powered software and services. The company wants its technology to be just as ubiquitous here as it is in the smartphone industry.

ARM announces Neoverse V1, N2 platforms & CPUs, CMN-700 Mesh: More performance, more cores, more flexibility:frend:
Citiraj:
Today, we’re pivoting towards the future and the new Neoverse V1 and Neoverse N2 generation of products. Arm had already tested the new products last September, teasing a few characteristics of the new designs, but falling short of disclosing more concrete details about the new microarchitectures. The Neoverse V1 represents a new line-up for Arm, with a CPU microarchitecture that is aiming itself for more HPC-like workloads and designs oriented towards such markets, while the Neoverse N2 is more of a straight-up successor to the Neoverse N1 and infrastructure and cloud deployments in the same way that the N1 sees itself today in products such as the Graviton or Altra processors. The big promise of the V1 is its extremely large performance jump over the N1, coming in at an IPC increase of +50%. This sounds large, and it is, but it’s also not all that surprising given that the microarchitecture essentially is 2 microarchitecture design generations newer than the N1, even through from a infrastructure product standpoint it’s only one generation newer.

Architecturally, the N2 is a newer core than the V1 and takes a higher architectural baseline as the foundation of its capabilities. It’s Arm’s first disclosed Armv9 capable core, including important new features such as SVE2. The company states that the new design should still achieve an impressive +40% increase in IPC compared to the Neoverse N1, which is actually substantial given the fact that we’re promised only a linear increase in power and area. In terms of the memory capabilities, we noted that Arm expects hybrid architecture designs which would employ not only many more DDR memory controllers, but also integrate HBM memory. By now most readers will be familiar with AMD’s chiplet approach, and it’s a general architecture most vendors are heading towards given the slow-down of Moore’s law. Arm’s CMN-700 also allows for designs that are eerily similar to what AMD uses today, where a system can have a central IO Hub along with auxiliary compute dies.

It could arrive as early as July in time for next-gen MacBooks. Apple's successor to its M1 Apple Silicon chip could arrive in MacBook computers by the second half of this year, according to a report from Nikkei. Tentatively known as M2, the processor has reportedly gone into production and could start shipping by July 2021. The chipsets will be produced by fab giant TSMC using its latest technology, known as 5-nanometer plus (N5P). Production of the chipsets will reportedly take at least three months. As before, the M2 would be a complete system-on-a-chip, with CPU, GPU and AI processors all integrated.

Ako će ARM ići u ovom smjeru - poboljšanje performansi uz umjerenu potrošnju el. energije - bit će to veliki udarac i Intelu i AMD-u. Pri tome ne mislim samo na consumer segment računala već i na serverske platforme. Svakome će biti interesantno da dobije 20% niži račun za struju uz iste performanse.

Ampere roadmap update: Switching to in-house CPU designs, 128+ 5nm cores in 2022:kafa:
Citiraj:
For people not familiar with Ampere, the company was founded back in 2017 by former Intel president Renée James, notably built upon a group of former Intel engineers who had left along with her to the new adventure. Ampere’s next generation "Mystique" Altra Max is the next product on the roadmap, and is targeted to be sampling in the next few months and released later this year. The design relies on the same first generation Arm Neoverse N1 cores, at the same maximum 250W TDP as a drop-in replacement on the same platform, however with an optimised implementation that now allows for up to 128 CPU cores – 60% more cores than the first iteration of Altra we have today, and double the amount of cores of competitor systems from AMD or Amazon’s Graviton2. Today’s big reveal comes in regard to the microarchitecture choices that Ampere is going to be using starting in their next generation 2022 “Siryn” design, successor to the Altra Max, and relates to the CPU IP being used.

Starting with Siryn, Ampere will be switching over from Arm’s Neoverse cores to their new in-house full custom CPU microarchitecture. In fact, Ampere explains that what the move towards a full custom microarchitecture core design was actually always the plan for the company since its inception, and their custom CPU design had been in the works for the past 3+ years. The company wouldn’t comment on the exact status of the Siryn design right now – on whether it’s been taped in or taped out yet, but they do retierate that they’re planning customer sampling in early 2022 in accordance to prior roadmap disclosures.

The “Mystique” code-named Altra Max design will be characterised in that it’s able to increase the core-count by 60% versus the current generation Altra design, all while remaining at and below the same 250W TDP. the relative positioning against the Altra Q80-30 and the EPYC 7742 would indicate that the new chip would easily surpass the performance of even AMD’s latest EPYC 7763. Ampere actually discloses the SKU model name being used for the comparison, which is the "Altra Max M128-30" – meaning for the first time we have confirmation that all 128 cores are running at up to 3GHz clock speed, which is impressive given that we’re supposed to be seeing the same TDP and power characteristics between it and the Q80-33.

Rumours of an ARM IPO emerge as nVidia's acquisition hits regulatory hurdles:kafa:
Citiraj:
nVidia's ARM acquisition may face delays, as the GPU giant's facing more regulatory scrutiny than expected. nVidia expected their ARM acquisition to be closed by March 2022, though that end date now seems incredibly optimistic given reports of nVidia's delayed paperwork. The Telegraph has reported that ARM is considering an IPO (Initial Public Offering) as a backup plan should their deal with nVidia falls through. ARM has denied the report, as Simon Segars, Arm’s chief executive, stating that “There is no IPO planning going on at Arm, we are 100pc focused on closing this transaction.” Should nVidia fail to get the approval of all regulators, their ARM acquisition deal will fall through. While nVidia plans to acquire ARM before March 2022, the company has the option to extend its deal's deadline until September 2022. From there, nVidia can either renegotiate their deal and try again or put an end to their acquisition plans.

Should the European Commission receive nVidia's paperwork in September, regulators could still take six months or more to decide whether or not to approve the deal. This makes nVidia's original March 2022 deadline seen incredibly optimistic. nVidia does not have the power to rush the EU's regulators. As Jonathan Branton, head of competition at law firm DWF, puts it: “No regulator will allow itself to be pushed into a corner and having to make a decision in a timeframe it’s not happy with.” While nVidia's approval from the EU might delay proceedings, China may prove to be a larger hurdle to overcome. China is infamous for allowing approvals for large mergers to take from one year to 18 months, a factor that could push nVidia's ARM acquisition past their extended September 2022 deadline. Should ARM be acquired by nVidia, the company will fall under US ownership, a prospect that China is wary of. Beyond that, there are ongoing problems with ARM China, ARM's Chinese joint venture, which has seen the joint venture go rogue as ARM failed to oust the division's Chief Executive, Allen Wu.

Should nVidia acquire ARM, a US-based company, China will face the prospect of further sanctions from the US to limit its use of ARM technology. At this point, China remains a wild card, one that could make or break nVidia's ARM ambitions. As it stands, a lot of people are against nVidia's plan to acquire ARM. For starters, nVidia is an ARM licensee, a factor that would make nVidia a user of ARM's IP and the controller of ARM's direction as a company. Currently, ARM is the Switzerland of the technology industry, an independent entity that licenses its IP to a broad range of customers, including AMD, Apple, Broadcom, Qualcomm, Samsung, and many more. nVidia ownership of ARM will allow nVidia to push ARM's development plans into areas that primarily benefit nVidia's hardware, potentially allow nVidia to withhold IP from licensees until after nVidia implements it (giving nVidia an unfair advantage), or increase their license costs to squeeze the margins of its competitors. While nVidia has the money and expertise to push ARM forward, nVidia's ownership of ARM remains a contentious issue. Beyond the issues raised in this article is the UK's loss of ARM to US ownership and the potential mass exodus of ARM licensees as nVidia's competitors seek to create a non-nVidia alternative to ARM's architecture.

Will AMD get back into ARM server chips?:frend:
Citiraj:
There was a bit of a kerfuffle this week when it looked like AMD was changing its position a little bit on whether or not it would get back into designing and selling server chips based on the Arm architecture. The funny thing is that the world has changed around AMD, and a lot of it for the good, as its EPYC X86 server processors have attained around ten percent market share (by shipments), but its position on Arm servers has not really changed. AMD’s top brass has said all along that if customers wanted Arm chips, it would make them. Well, maybe AMD’s position, internally, has changed just a little now that the server market has changed so much since the summer of 2015 when AMD stopped its “SkyBridge” X86-Arm shared socket effort, launched in 2014 with much fanfare. Prior to that announcement, AMD’s Opteron Arm server chips based on its homegrown “K12” core were expected in 2016 and were pushed out to 2017, and they were SoCs that combined Arm cores and GPUs, much as the “Seattle” Opteron A110 was. Seattle fizzled because it was too underpowered to do anything useful in the datacenter. So AMD started shutting things down, killing off SeaMicro microservers and its interconnect, killing off Arm server chips, so it could just hunker down on the EPYC server CPU. Because, frankly, the Arm server chip demand never materialized.

AMD has plenty of interesting options when it comes to Arm server chips. First of all, as Cavium, which is now part of Marvell, proved so well and as AMD proved with its Seattle Arm chips, it is not all that hard to do a global replace and put Arm cores in the same place where an Octeon NPU core or an X86 CPU core is in a processor design. The uncore stuff can be recycled, and if you are an Arm licensee as AMD is, you can take some of the stuff in the guts of the core — branch predictors, caches and cache hierarchies, vector units, other accelerators, memory controllers, and peripheral controllers and reuse these elements in an Arm server chip. So if a hyperscaler (not likely a public cloud since no one has a lot of Arm server workloads outside of the hyperscalers) doesn’t want to do an Arm server chip design all by its lonesome, they could hire AMD to do it.

While that would be interesting, what we think would actually be far more interesting is for AMD to pull a sequel to the SkyBridge effort and create a common socket for X86 and Arm server chips that is completely neutral about what kind of chip is plugged in. This is a real value for those who want flexibility, and if it really wanted to hedge its bets, it could do server CPU designs that had a lot of the components between X86 and Arm — and maybe someday RISC-V — be as common as possible.
