It's a little more complex than that, IMO. For starters, IBM did also do the CPU for the GameCube, and that was likely a part of the Wii using an upgraded PPC arch for that. On the flipside, there is the theory (I think even Copetti brings it up in their XBox 360 Architecture breakdown [0]) that IBM using the Cell PPE for the 360's tri-cores left a sour taste in Toshiba, but more-so Sony's mouths. I think the big 'X…
>There's part of me that asks, if AMD had an ARM core, if we would have all Consoles powered by AMD chips now. Nintendo likely bought into Tegra because it was an ARM core, and for better or worse their mobile stuff by the time of making that choice had 15+ years of proven ARM success (GBA, DS, 3DS) behind it. AMD worked on a ARM core https://en.wikipedia.org/wiki/AMD_K12 but I'm not sure it would had work, they were…
The story about that AMD ARM core is that they were making it for Amazon. Performance was not good enough so it was canned. Amazon then went on to make their own chips called Graviton.

#10520 years ago, IBM had their eCLipz initiative to unify z and POWER. What actually shipped was two different CPUs sharing some design, but some of the media reports on it made it sound like it may have originally been more ambitious-one CPU with two instruction sets.
If that’s what it was, looks like they finally shipped it, just replacing POWER with ARM

It’s a rebranding of ML which IBM has promoted for quite some time, used in a rather conventional fashion.
AI does not always mean LLM.

I never said it did? ML has inference too, so...

ARM has better software support for AI applications and half of their presentation was about their inference accelerators that can go in the mainframes (and POWER machines). IBM mainframes are almost designed by their users. The previous generation skipped a lot of speed boost on the CPU side because their users didn’t want the machine to blow over their power delivery limits. Now, with their architecture behind it,…
Does anyone else make an ARM CPU that is expressly designed for performance with good cooling ?
Mainframes are exquisitely "balanced" machines that match processing capacity and IO for a relatively small set of workloads. You won't see mainframes doing scientific number crunching or AI training, but you'll increasingly see them adding more AI inference into their transaction processing workloads for things like fraud and anomaly detection. While their CPUs are prodigiously fast (the one announced is designed to run at 5.7 GHz, and the cores themselves are huge compared to other architectures), a lot of emphasis is placed on the IO systems that connect the machine to storage and other systems so that the CPU is busy all the time. It's very normal to run a mainframe at close to 100% CPU utilization.
Re: IBM Unveils Next Generation Dual-Architecture Processor for IBM Z and LinuxONE
#109Not explained in the article: Every single physical core on the chip decodes and executes both s390x and Arm AArch64 instructions, dynamically switching between the two ISA modes and convert them into micro ops. Mode switching is hypervisor-driven. And those chips are fast. 5.7 Ghz 2nm node. For who: When you need to run Linux programs on high security, mission critical environment. Others should not care.
So why the 2nm x86 chips are clocked so low?
Why couldn't they be 6GHz? x86_64 ISA did it again?
That said IBM should add RISC-V support.

A single mainframe can handle workloads that would take dozens of x86 cloud servers, with nine nines of uptime. If you can afford it it pays for itself in terms of reliability and scalability.
That may be true but the dozens of x86 servers are cheaper and easier to use.
