Can an AI datacenter be beautiful?

W

The computer industry has always had a weak relationship with beauty. Recently parts of the valley have become a bit self-conscious of their ugliness. We need a “new aesthetic” and billionaires will grant their couch coins for good ideas. Combine this self-consciousness with an AI datacenter backlash and you get the suggestion: AI datacenters should be beautiful.

Can our datacenters be beautiful? Architecturally, yes, absolutely. Datacenters are a box. Apply good architects to a box and you get the Institut du Monde Arabe in Paris. Most of the Twitter posting I’ve seen has offered the idea—perhaps novel to software engineers—that it is possible to reskin a box. We could make them 12th century castle forts, or Parthenon de Plano, Texas. I’ve been thinking about datacenter economics a bit lately, and so I’d like to go a little further and work out the financing.

Can the trillion-dollar OpenAI afford beauty?

Ugly Stargate Abilene

Let’s take the OpenAI Stargate project’s Abilene, Texas site for our worked example. When finished this site will house 400,000 Nvidia GB200 (Blackwell) GPUs across eight buildings. The image at the top of this post shows just two of those eight buildings.

ChatGPT 6.0 will gain exactly nothing in its benchmark scores from the prettiness of the walls of Stargate Abilene, Texas. Nevertheless, could it afford to grant us monkeys an eye opener? Absolutely it could.

My simple and approximate financial model puts the GPU-hour cost of Stargate Abilene at $1.826.

The bones of this breakdown come from the latest (7th) edition of the quantative Computer Architecture textbook from Patterson, Hennesey, and Kozyrakis. What’s important to notice is that the capital expenditure (CAPEX) for the IT equipment nearly dwarfs the cost of facilities, and the IT equipment has a much shorter depreciation time.

To get to a per-GPU-hour cost we need to translate from CAPEX to operation expenditure (OPEX). Upfront costs combine with depreciation to become costs-over-time, and we add in ongoing service, maintenance, and operations cost, e.g. people! Assume 300 fully loaded staff at $250,000/year (generous). CAPEX costs are converted to monthly costs using a 5% capital recovery factor over each amortization period.

Converting to OPEX

Ugly Stargate Abeline is spending 75% of its OPEX on IT equipment alone. We’re going to see just how cheap it is to buy beauty when your datacenter cost sheet looks like this.

To turn this cluster of buildings into a soul warmer you need only raise the GPU-hour cost by 0.25%–0.5%, to $1.830–$1.834 per GPU-hour. Yes, half of one percent.

I’ve chosen here to beautify Stargate Abeline using the work of New York’s Monumental Labs. They use robotics to dramatically drop the cost of producing stone ornamention. They’ve recently completed restoration work at Carnegie Hall and The Frick in Manhattan.

OPEX

With the stone cladding range, beautification adds $0.00422–$0.00847 per GPU-hour, or about $0.00634 at the midpoint. The new GPU-hour cost is $1.830–$1.834, with a midpoint of $1.832.

Even if my analysis is off by 10x, architectural beautification is absurdly cheap when GPU capital expenditure is at this scale. I beleive it does reinforce a sense of blindness and meagreness in Silicon Valley. In San Francisco one is surrounded by so much beauty—the Painted Lady’s, the Palace of Fine Arts, of course the bridge. But tech made none of that. They adore the bridge, as they should, but it is a bridge they did not build.

It is plausible that this industry of immense wealth, one that can make a 22 year old in college sweatpants a billionaire, may fail to leave a legacy of public works. In my city, I walk with millions of others by the good works of a grocer (Woolworth), an automaker (Chrysler), and a steel magnate (Frick). In Brooklyn a sugar refinery is proudly restored next to a park named for it. Just five years ago a New York billionaire put in $200M for a little park.

Maybe Silicon Valley’s noble era is coming. They’re in such a rush to cure cancer. But the population is clearly uneasy, and part of it is a sense that the Valley is unendingly rapacious, that it lacks a public spirit, lacks vitality.

They might actually put a country full of Einsteins in a datacenter that looks like a Costco Wholesale. In the bad old days we had just one Einstein, but we at least put him in a building worthy of his work and caring for the people that walked by its walls.
