@British_Airways you sometimes get lots of grief on this platform but this is all praise: thank you for putting our morning rolls and tattie scones as part of the breakfast in the Edinburgh lounge. Totally elevated the breakfast.

Strange @WSJ article about Jensen renting out the San Francisco opera house last year for a performance of “The Monkey King.” The article essentially frames it as a gilded age “champagne and opera” style event for “AI’s kingmaker.”

Makes for a good story, but the reality was quite different.

Mostly because the article leaves out an important detail; Jensen’s stated reason for hosting the event: helping to revitalize San Francisco’s downtown and the opera house. This was the actual focus of his speech, not the “champagne and opera” joke. And the event was full of Jensen’s good friends as well as various AI figures.

When I spoke with Jensen that night at the opera, the first thing he said to me was that it was really personally important to him to help downtown San Francisco get back to its glory days. It was essentially a fundraiser for the opera and San Francisco where no one was asked to contribute. 

As someone who gets asked to contribute to a lot of charities and go to a lot of charitable events, I thought this was a generous and classy gesture on Jensen’s part and I’m sure many attendees took it upon themselves to donate. I certainly did!

Article would read differently with these facts, which kinda seem like the most important ones to me.

As far as the illustrious AI figures in attendance, important to note that the CEO of Jensen's largest accelerator competitor was actually at the opera at Jensen's invitation the night I was there; which again is quite at odds with what is described in the article. And please note that Nvidia’s largest competitor is not actually AMD.

One of the defining features of tech in the 90s was that the CEOs generally hated each other. I think it is good for the world and the AI industry for someone like Jensen to bring the industry together and I'm happy that he is doing this.

If anyone believes that any of the companies referenced would’ve struggled to raise money without Nvidia’s participation - they are simply wrong. I know because I was around many of these fundraises. And OpenAI’s embrace of AMD is object evidence that companies who have raised money from NVIDIA feel free to use competing products.

Finally, kinda sad that the net effect of this article might be to make other CEOs less likely to host comparably civic minded events.

I hope that I am wrong and that both Jensen - and other CEOs - are undeterred by this article. Nice for people to give back.

@HotAisle Green team on the other hand has been able to hit 90%+ on axpy and 95%+ on reduction since Volta (barring Ampere which lost a couple of percent).

[Maddy Scientist @maddyscientist]

@HotAisle Posting peak bw on AMD is comical compared to the sustained bw. Instead plot sustained and you’ll see NVIDIA at around 90% sustained of peak and AMD in the mid 70s.

[Maddy Scientist @maddyscientist]

@HotAisle Infinite use case dependent, sure, but if you have undersized buffers or power limited, you can’t hit peak no matter (90%+ efficiency). MI325 is small improvement over MI300 (add a couple of percent of peak) and MI325 a wee bit more again (into low 80s).

@SemiAnalysis_ How about actual sustained memory bandwidth rather than slideware bandwidth?

@timruss2 I read that initially as “USS Deviant”….

@khshind @iamgrigorev @stalkermustang True true

[Maddy Scientist @maddyscientist]

@iamgrigorev @stalkermustang I can hit 93% of peak on H100 without too much hacking. Anyone who says 90%+ isn’t achievable is spreading FUD

@deadbydawnfest any chance you’re going to make a comeback in 2026?

[Maddy Scientist @maddyscientist]

@FlyLoganair Thank you for the response. With the expanding number of 🥃 distilleries and visitors to the island, I’m sure there would be high demand.

[Maddy Scientist @maddyscientist]

@FlyLoganair any plans to restore the sadly missed Edinburgh-Islay route?

Hey @TeamYouTube , your automated system banned this channel for absolutely no reason. Appealed and denied, for no reason. This is completely unacceptable, and a slap in the face of all creators. Claiming this is irreversible is deeply concerning too, and simply cannot be true.
