All the great minds that worked on Zen really show in its performance !

The thing that's neat about risc-v (if I understand), is that beyond the core design the new optional stuff is defined in optional extensions. So if I want to make a music player, I could just buy a risc-v processor that only implements the core plus just the extensions that are of use for audio encoding decoding. I could leave off stuff related to graphics for example if that had no use in my music player

I think this might be the 12th time I'm watching this video. The importance of this video cannot be overstated

Amazing leader

Jim Keller was for sure 1 of the Fathers of Zen

Jim Keller: The Obi-Wan Kenobi of CPU Architecture, Master... I'm your loyal Apprentice 🤟🤘

I would like to see raspberry pi release a reduced x64 chip.

ISA doesn't matter. Let's talk about what does! The answer is always: That depends. As the software isn't written by humans anymore and code size is not an issue anymore the old requirements and constrains are irrelevant.

We write 2024, Mai. Let' face it, he has not foreseen the victory of Arm over x86 2022, when Apple already has switched gears, and he has not foreseen the raise of NVidia and GPU computing WILL be AI computing. So obviously, it was not so obvious. Finally, RISC (Arm) has beaten CISC (x86)- it was predicted more than 30 years ago, but didn't happen for some time.. I read the first books..

I have now seen multiple CPU designers, state that the architecture isn't really important. But in the CPUs actually out there there seems to be a huge power efficiency gap between ARM and AMD64.

Need moar JK.

ARM can't do division, pretty fail tbh

Now I understand why he comes in, designs an architecture, and then leaves for the next company. That way Future Jim won't have to deal with his mess.

Linear algebra is a high level description of potentially thousands or millions of multiplies and adds -- all very predictable from a terse equation and dependent on the exact data. This makes AI, Data Science and Statistics on a large scale possible. It should also enable physics and engineering calculations. All of this implemented in low level languages and callable from Python!

Why do people find it so hard to speak coherently these days? The interviewer is an example of that.

It could be an interesting interview if there was no kitchen background noise

"that's a problem for ron..." ... "later ron"

Instruction sets are like government. The bureaucracy exists to feed the bureaucracy.

Everybody keep saying instruction sets don't matter, except nobody could touch Apple in single thread performance with cores that run 30% higher clocks at 5x the power. Beat Apple, and then I'll believe "instruction sets don't matter"

Architecture shouldn't matter when you learn the best from each other. The issues arises when you have design decisions that's mutual exclusive in the long run and doesn't have a path forward.

What architecture/technology is Keller saying at 7m55s? The edit garbled the audio referring to an architecture that deprecated (sic.) a legacy mode. I'll have to dig out my architecture book.

Holy smokes, what a mind!

But "80% of executions being composed of 6 instructions" isn't the same as "80% of the EXECUTION TIME is spent on those same instructions".

LOL ~ I hate that, where future Jim comes back and goes "What the f ck did you do that for?"

How did Intel let Jim get away? I guess he probably felt limited there.

Somewhere between 20 and 80 percent 🤣😂

He explained everything so easily

This ceo may be technical but i would fire him as a marketer for the company.

Explains a lot....... thanks!!!

chiplet and ai processor is the future

When I saw Jim I knew it would be insanely great explanation.

Jim Keller is a smart dude

Oh, please, Patterson has been hyping his RISC for 40 years. He is just now competing with Raspberry and Orange Pi's. RISC-V has no discernible advantage over Intel, AMD, or ARM.

Okay but when will potato-computing supremacy be realized?

Absolutely golden content

ZEM arm never came to be right??

Hah. Keller has a painting from Vladimir Kusch behind him. A Russian painter now based in Maui

Is there a fully stable and official Python interpreter specifically tailored for RISC-V?

Lofty minds designing devices to be first utilized by the grosses souls.

why does every video begin with "What's your minimum specification?"

Very underrated guy. This should be a household name instead of guys like Musk.

I could listen to Jim Keller's insights for hours. Just serving him coffee I would feel like I'm wasting his time 😅

"what limit's computer performance is predictability". That's huge quote.

Jim gives the impression that he's a reluctant to be referred to as a mentor, but as a consequence of his unrelenting drive to complete the mission he's a still great mentor nonetheless.

No offence to the guy but I really could've used subtitles on this one. English is not my first language and I pretty much have no idea what he said.

This says it only has 12 views? Is that right?

What does “what’s your minimum specification” mean?

Really appreciate you for making these Ian. Thanks!

Great interview. Jim is a living legend. You ask questions I would want the answers to myself.

The parallels between CPU design and Operating System design are interesting. Uncontrolled complexity as a result of adding features but not removing features? Totally. Leaky abstractions as a result of 'quick fixes' and premature optinizing? Absolutely. I'm currently writing an OS for an extremely minimal system (as in, memory measured in kilobytes, cpu speed in single digit megahertz, etc). Am at incarnation 3 of the design now. Yes, the previous 2 worked, but as I kept adding features which were 'required', things got more complex, making for more involved decisions, resulting in more overhead. Poking holes in abstraction layers did speed up some things, but ended up causing longer lasting resource contention, which ended up lowering overall performance, etc. Incarnation 3 takes all the things from the previous 2 incarnations, but with a new and clean design, with clean and unbroken abstractions, resulting in less complexity, and removal of functionality which was in the end just providing alternative ways to do the same things. Without being a CPU designer, this discussion is still very relatable.
