I Want To Test This CPU

[@JeffGeerling]

I do like lots of fast cores. And I'm excited to see AMD, Intel, and Ampere all getting in on this game. Just wish these Ampere chips were made available for testing...

[@levieux1137]

One regret I'm having with their offering is that there's no high frequency CPU in the low-cores. The 32-cores was only at 1.7G, the 80-cores at 2.6 and the 128-cores at 3.3. That's the opposite of what's normally done. I'd have loved a 3.5GHz 32-cores for some use cases.

I think Qualcomm has a business model closer to Nvidia Grace than Ampere as described in this video, they sell a hardware platform for partners to implement. For that to happen you need a chip, but also time to build relations with partners. It won't be whatever most of us want to see however.

Seems too little too late. Their own slides barely show them beating out Bergamo which isnt new at this point, you now also have Intel back to firing at all cylinders trading blows with AMD in DC, and adding accelerators to Xeons to target customers who need more than general compute. Ampere is competitive, but not competitive enough to sway a meaningful amount of customers away from Intel and AMD, and those two are more competitive now with each other than they were in the last 5 year.

[@RobBCactive]

If a customer is buying use of blocks of cores, having dynamic frequency but with a constant power limit available to each block seems fairer. Then serial code can run faster when block threads are idle, which Amdahl's law shows can make a large difference, while highly parallel sections can benefit from wider power efficient processing. Determinsm has limits because the data is generally changing, if not the computation is redundant. Fixed frequency schemes are simpler for the CPU designer but pass the burden on effective job mixes to programmers and sys admins

[@geoffstrickler]

Yes, but there are significant limits to the performance scaling from frequency boosts.

[@RobBCactive]

​​​@@geoffstricklerabsolutely, otherwise we'd be blissfully enjoying the simplicity of uni-processors. Certain types love "fixed" but in reality it leaves potential on the table and you cannot control everything. A larger pool of shared resources, should be a benefit. Less dense logic and faster cells are required to hit high frequencies. Fixed frequency makes for longer tails on jobs, so you'd need to schedule more different tasks simultaneously which often reduces cache effectiveness. With a large pool of cores, you can run at higher utilisation while meeting service guarantees, it's only the idea of assigning specific customer blocks with a low core count that burdens them with a utilisation issue. In the mainframe days, it was usual to bill by the CPU second on time sharing systems.

[@skunkwerx9674]

@@RobBCactive Would you say once we reach the limit of dennards law that multi frequency designs will become more frequent or less frequent? On the one hand the lower we get the higher the noise, so we made stopgaps like backside power delivery and materials adjustments to reduce noise on designs while reaching size targets. On the other hand the noise may become so high at higher frequencies and lower sizes we normally expect processors to shift to, and frequency scaling will become much more difficult. Maybe static frequency is the future?

[@RobBCactive]

@@skunkwerx9674 Dennard scaling ended long ago, it used to be that a shrink was faster, cheaper and more efficient.

[@geoffstrickler]

@@RobBCactive I think the next big steps will come in the forms of (roughly in this order): 1. Backside power delivery. Already in the works. 2. Asynchronous logic. Probably not a fully asynchronous (clockless) design, but asynchronous subunits with limited clocked or triggered gating. Already demonstrated in small circuits, but not used much or at all in existing LSI designs. 3. More/better parallel algorithms.

[@levieux1137]

One really great use case for these affordable chips is development. We have a 80-core at work and I use it every single day for testing code for scalability, as a build machine when I need to bisect some regressions since it builds super fast, to validate various assumptions etc. The machine is small, super fast, not very expensive and lends way more services to me than the 24-core AMD EPYC that's next to it and that I start once every 4 months.

[@movax20h]

I like Altra. Also I like they do not do BS marketing, or AI hype. They work, then deliver. Not super frequently, but very solid and industry leading. (the "predictable" performance marketing, or comparisons to x86, are a bit misleading, because it highly depends on workload). Also do love you can buy motherboards in various form factors, and systems from various vendors (Asrock, Supermicro, Tyan, Asus, Gigabyte mostly). I think most of the secret souse is in SoC mesh and coherency fabric scaling, and L3 partitioning and memory bandwidth partitioning. Similar to Intel RDT. It is hard to believe their new CPU is based on a custom core IP. Maybe custom core IP is also a hedge, so they can pivot to RISC-V by changing frontend, and doing some adjustments, if needed. (Sure it would require a lot of software rework, but who knows). Extrapolating. Prospect of ~500 cores from Altra in 3 years, is bonkers.

[@libertysound8575]

ive had my arm based computer for two years and its life changing

[@noname-gp6hk]

Word on the street is Amazon might be stopping graviton4 development due to the competition heating up between the x86 vendors. With both of them yielding cloudy x86 server CPUs that are very armlike in performance and power characteristics, doesn't seem like the R&D cost to go custom chips is as attractive as it was five years ago.

[@guibirow87]

Graviton 4 has been in preview since 2023 and available to some customers, why wold they do that and waste all the investment made? Maybe true Graviton 5?

Unfortunately for Ampere, Intel just launched Sierra Forest at Computex. 144 cores on the mainstream, but up to 288 cores on the advanced platform. They are E-cores, but those Crestmont cores are quite performant, pretty handily beating ARM designs. And combining E-cores with the Intel 3 process, the power efficiency is class leading, beating all of Intel's existing Xeons *and AMD's* Epycs in efficiency.

[@RobBCactive]

Bergamo has a higher thread count, the independent review I saw suggested SF only exceeds at very high utilisation while Bergamo is better at burstier loads. Turin dense on TSMC N3P is expected Q1/25 with a maximum of 12x16c, so Ampere has that competition too.

You might have missed AMD Bergamo using Zen 4c cores. Half the size, half the cache, and optimized for cloud, but otherwise functionally identical to Zen4. They beat Intel to the punch for enterprise E cores.

[@tomstech4390]

@@TechTechPotato ​ Oh I'm aware I was just daydreaming. (Personally not a fan of Ecores and wouldn't call ZenC an Ecore but that's my bias) Intels ecores have half the IPC of Pcores, no SMT, removed instruction support and a shared L2 cache. ...IF AMD did the same thing could they make a core 1/2 the size of Zen4c/Zen5c? How big would 4x 4core clusters of Cortex X4 be? (or Jaguar just for fun) -CPU caches grew to 3 tiers... L1 to L2 to L3 and briefly L4 -Smartphones have 3 tiers... of X2 plus A710 plus A510 -Arrow Lake might be doing the same with the SOC ecores separate from the compute tile. AMD is doing good with just Pcore and "not so big" Pcore, just some fun brainstorming what options they have and what it might look like. Wendell (reading Phoronix) recently covered Xeon E, he mentioned that Bergamo's weakness was lots of tiny environments in containers, hyperscalers might prefer more small cores (arm) to more powerful ones with SMT plus the aded benefit of more power granularity.

AMD is also working on ARM I think its called Soundwave, but seemed mostly mobile, iirc.

If you're thinking of skybridge, that died several years ago. I asked the architect.

[@RobBCactive]

MLiD has reported AMD sources on future management plans with more variants that could include cutting AVX512 as well as cache sizes. Though designers might be pushing back against increased workload. But the semi-custom arm (pun intended) did cut down the fp units for the Zen2 variant in the PS5. There's disadvantages to fragmenting the ISA, having a lot of chips out with features encourages software support. I can see Intel were forced into E-cores, but now they're dropping HT, while AMD SMT still offers a context switch free second thread that can aid core utilisation, so are they under pressure to reduce core area? At N2P leaks suggest 32c/64t CCDs so core count per socket is planned to grow.

I wouldn't be totally opposed to getting an AmpereOne based system but I really need a plain English guide on how to use ARM intrinsics / AVX equivalent instructions, and a realistic performance comparison to the competition; there was a lot of marketing with Ampere Altra, and a lot of reference to "Ampere optimized Pytorch" and so on, but when I can pick up a Xeon Scalable 5th gen, or an Epyc 9004 series and just grab any software off the shelf and know it works, with a huge wealth of legacy resources online to learn how to use them effectively, it's just a bit too scary to take the plunge.
