Broken Silicon's next guest will be Wendell from Level1Techs.  We plan to discuss:

  • Intel Sapphire Rapids
  • AMD Genoa, Genoa-X, and Bergamo
  • Intel vs AMD server strategies over the next 3 years
  • Intel Granite Rapids
  • Intel Sierra Forest
  • i9-13900KS vs Zen 4 X3D
  • Anything else you guys want!

Wendell is able to speak to just about any subject related to silicon, so don't be shy! Put your thoughts, questions, and comments below!  Just be sure you are concise, use good grammar, and be respectful to have your submissions considered.

You ~36 Hours (Till Noon 1/22/23 US Central Time) to submit below!

While the MI300 is obviously a successor to the MI200 series, might it be better thought of as a new parallel platform to EPYC? For example, the reference design that AMD showed had 3 sets of CDNA compute and 1 set of Zen 4 compute with 24 cores, but based on what AMD has said before they could just as easily make a configuration with 4 sets of Zen 4 cores giving it a total of 96, the same as Genoa, but with 128GB of HBM3 memory. Paired with CXL based memory, that could make for an interesting server for a number of scenarios. Do you see any other interesting uses for MI300 or the packaging technology behind it?

Hey Tom and Wendell. Linux gaming has come a long ways in the past few years. The introduction of the Steam Deck has helped increase the Linux user base. Do you see Linux gaming reaching feature parity with Windows in the near future (e.g. HDR support, Direct Storage, equal developer support, etc.)?

Question for Wendell: Do you have any recommendations or experience to share for a good Linux laptop as a sysadmin / developer workhorse? Would you go AMD or Intel and any specific manufacturer, model or other suggestions to look into? (Must be x86) I recently made some sobering (read: disappointing) experiences with running Ubuntu on a Thinkpad p14s Gen3 with an alder lake i7 1270p. Battery life is meh, cooling fan is noisy even at low load and overall I am not impressed with it at around 2000 € (coming from an Intel MacBook Pro).

As a follow up, does Microsoft's Dzn mesa code hitting 99.75% vulkan 1.0 compliance make this easier to develop for through WSL?

How useful are accelerators if they aren't on every model that generation, and possibly require an upcharge? Consumer seems to require a hardware feature to be present several generations before developers target for it. Enterprise can be more nimble, but would they?

Hi Tom, and hi Wendell -- Love your work! Wendell, you have often described yourself as a "computer janitor," but what does that look like in practice? What would be a typical work assignment or contract for you? I get the impression that tech companies hire you to implement, profile, and optimize complex workflows involving multiple software and hardware components, including having you apply patches to open source components to enable or optimize the customer's use case. How accurate is this perception, and how often do these patches get upstreamed? How does one break into the computer janitor biz?

Another question for Wendell: When Alder Lake came out, you reported that the heterogeneous core microarchitecture was causing scheduling problems on Linux. This was surprising to me, because Android (which uses the Linux kernel) has primarily targeted big.LITTLE ARM devices for over a decade. I had expected that these codepaths in the Linux scheduler would have been pretty much plug-and-play with Alder Lake. Can you talk about how Alder Lake and Raptor Lake differ from big.LITTLE on ARM, how that affected the requirements for the kernel, and what the obstacles were (or are) to applying CFS to ADL/RPL? Also, what is the current state of play, is this working better in Linux now? Do you think Linux will have good scheduling on the heterogeneous 7950X3D on launch day?

What do you think of this new development in Moore’s law since we knows it’s dead and all. Link for the article I’m referring too. https://www.phonearena.com/news/solution-discovered-keeps-moores-law-alive_id145013

Hello Wendell and Tom, Can you talk about AMDs GPUs in workstations, particularly and insights/predictions about near future viability and competitiveness? It's really rough out here with no alternative to CUDA,

Hey Wendell and Tom! Very excited for this podcast and I hope you both are well. AWS is pushing Graviton instances both externally to customers and internally to service teams with increasing incentives to get everyone on board. Do you ever hear anything from AMD or Intel engineers worried about Amazon putting this kind of pressure on the server market with their own ARM based chips in a way Apple never could?

Hi Guys, how close are we to a situation where we have a generic substrate and can order custom heterogeneous compute "chips"? For example, I'd like 16 cores of Zen4, 32 workgroups of CDNA3, an FPGA and an AI inference accelerator and 64 GB HBM3e please, all on the same substrate in the same socket. With the SuperAPU that was shown off at CES that seems really close.
