I believe the top question in most tech investors' minds is - "where are we in AI?" I wrote a piece from the perspective of someone who spends a lot of time thinking about the public markets AND speaking with private companies https://t.co/aOZ0vUMnq5

Extra outtake clip from latest @BG2Pod with Jensen @altcap Contrary to popular hypersensationalist rhetoric -- that we are in a massive AI glut -- we are likely in a stretch of structural compute shortage. Google announced in May that tokens had grown 50x y/y, and doubled again

Basically this - can do the math from a fully loaded cost perspective (15Bn+ of fixed costs in a DC) or from revenue perspective (like this) I think #1 being wrong is even more bullish for $NVDA bc NVDA can be used for all accelerated workloads vs ASICs / other GPUs which don't

The $NVDA long pitch is this: You have a finite space for a rack - this is limited by the walls of a DC, but mostly by how much power is available. On that footprint, you can place your own chips, NVDA, potentially ASICs, but the end goal is to serve tokens that you can sell +

Some analysis on "50m H100 equiv" target of Elon & xAI Assuming power / perf improvements: 50m H100s = 250x today's compute But reflects ~4M total GPUs and energy footprint of 11GW ! My best guess is Feynman will cost ~7x Hopper, but offer 25x perf (3-4x TCO passed along)

GB300 bring up at CoreWeave. GB200 and GB300 going to hit AI infra like a wave. Once the majority of AI infra install base shifts to rack scale 72 GPU domain, so will the models and capabilities. Models and SW = water, will just pour more as the vessel (hardware) expands

Interesting Jensen quotes at GTC Paris: "we estimate around $1.5T of accelerated DC demand" "do believe most of the ASIC projects will end up getting cancelled" "We are going to sell hundreds of billions of GB200/300" "RTX Pro is the biggest opportunity ex GB" $NVDA

@ Snowflake Summit, @saranormous asked @sama what he'd do with 1000x more compute after trolling ("I'd use 1000x compute to train smartest AI model, then ask that model how it'd spend 1000x compute") he said "we see tons of use cases in chatgpt and inside enterprises using
