    Normally I’d be suspicious of these kinds of megastructure projects but Vegas is the city that figured out how to get damn close to net zero water use from the Colorado so I’m willing to start off with the benefit of the doubt for the city leaders that ok’d this.

    Wait, why do they need 150 GPUs for a 1.2 megapixel display?

    That’s less than 1080p!

    Who engineered this monstrosity?

      They say there are 16 screens inside, each with a 16k resolution. Such a screen would have 16x as many pixels as a 4k screen. The GPUs power those as well.

      For the number of GPUs it appears to make sense. 150 GPUs for the equivalent of about 256 4k screens means each GPU handles ±2 4k screens. That doesn’t sound like a lot, but it could make sense.

      The power draw of 28 MW still seems ridiculous to me though. They claim about 45 kW for the GPUs, which leaves 27955 kW for everything else. Even if we assume the screens are stupid and use 1 kw per 4k segment, that only accounts for 256 kW, leaving 27699 kW. Where the fuck does all that energy go?! Am I missing something?

        This is a complete shot in the dark but could the huge power draw come from needing some intense industrial cooling/airflow stuff in/on the sphere?

          The big power draw is because of the sheer amount of light it dumps out. You try lighting up 54,000 square meters of LED panel to a few hundred nits like a pc monitor, and see how much power it takes.

        Ah, you’re right, that’s 1.2 megapixel for the exterior, and 132 megapixel for the interior.

        That’s a substantial increase, but it’s still the equivalent of about 16 4K screens, which absolutely does not need 150 GPUs!

        Edit: No, I was wrong, this entire monstrosity is overengineered to over two gigapixels on the inside, and that’s absolutely ridiculous.

    I don’t know what they need so many GPUs for. There’s 16 displays inside, and the sphere itself has fewer pixels than even 1 of the internal displays. You could probably run the sphere off a laptop if you aren’t trying to do anything fancy.

    Maybe they plan on doing crazy live simulations on it or something. I can’t imagine what kind of displayed image would actually use all 150 of them. Nvidia A6000 cards are damn powerful.

        My job has been to run things on GPUs for almost 10 years now. The only thing anyone practical is doing on that many GPUs is AI training, massive scientific simulations, or crypto mining. 1 or 2 of them is enough to run something like ChatGPT.

        Real-time graphics it turns out don’t scale well across multiple GPUs. There’s a reason SLI has gone away for consumer GPUs. At the current ratio, each of those $3000+ GPUs is only driving 8000 pixels (assuming each led puck is being used as 1 pixel, given their size). It makes no sense other than bragging rights

        It does seem suspiciously like they picked 150 completely arbitrarily to make the project sound impressive, when they could have easily done it with 20. I’m sure a bunch of people in the middle made a bunch of money off that transaction too. Or like you said, maybe this is Nvidia doing some guerrilla marketing

      Solar only works during the day. During night you need batteries which are not renewable. Mining lithium trashes ecosystems and we probably have enough for like 50 more years at this rate, cobalt is extracted through slave labour. And we’ve seen how well recycling works for other materials which are less complex. So all these renewables aren’t all that green in every aspect. Unless we solve the energy storage problem it isn’t as simple as putting up more panels.

        You know, I’m getting really sick of these comments where people think they know what they’re talking about and repeat a bunch of talking points about lithium.

        Lithium is not going to be the basis of a renewable grid. We need it for EVs because it’s the best Wh/kg that we have right now, but we don’t care so much about weight for grid storage. Cost/kg is the main measure we care about there (though there are some other considerations in specific conditions). We already have tech being deployed in the field that’s better than lithium for grid storage. Flow batteries, flywheels, pumped hydro, or just heating up sand or rocks. Others, like sodium batteries, are being manufactured and will probably find their way into real products in the next few years.

          Chill, no need to be stressed. Part of the ideas you mentioned are already implemented in some cases, but they are not without drawbacks. Pumped hydro is good, but has high maintainance costs, messes with the fish and requires large bodies of water, how do you get tbat in the desert? Flywheels have good inertia, great for stabilizing the grid, Ireland has some for that exact reason, but can’t store a whole lot. And heating up roxks and sand may work if you need heat at night, but you need electricity, so you need water to turn into steam to produce it. Sodium batteries look the most promising, we’ll see how they develop. But until we get these storqge facilities built, adding more solar would only destabilise the grids even more.

              What propaganda? I think you have to go back and read my post once more… The thread started from solar panels in the desert. At the moment the most widely used grid storage is pumped hydro, how will you do that in the desert? Next most used tech RIGHT NOW is lithium batteries. Other solutions exist, but how many are there implemented and ready to capture that energy right now? Oh, not so many? Then putting up more solar panels hoping that one day we have the storage for them is foolish, these panles lose efficiency over time. I don’t have an agenda to spread, there is no propaganda, I am only talking about the an issue which exists, which is energy storage, for which we have some solutions, with their pros and cons, but not close to being implemented.

        Sodium batteries (which are on the market now) are way more environmentally friendly than Lithium batteries.

        The materials are very accessible by comparison to Lithium batteries and they’re way more stable.

      The article says that, for the GPUs, they can have a “maximum power draw of 45,000 W at full tilt”.

      The 28 million W comes from the full system, and surely the massive displays, LEDs and eventually sound system makes up the bulk of that, the gfx cards are a rounding error…

      I don’t know about power, but Vegas is actually incredibly water efficient. Due to the way the water rights work with the Colorado river, they’re not allowed very much, but it doesn’t “count” if you put it back in. So nearly every drop they use is treated and put back (probably cleaner, tbh). Boggles the brain, but somehow it’s actually a fairly sustainable city. More than any other other major metro, in any event.

          Thrilled you asked! So yes: Treatment is always required, but the final destination of the treated water can vary. For instance, in a lot of places they may have municipal water TO a home or business, but that may be discharged to septic, as opposed to the river. Also in a lot of areas, water may be taken out of an underground aquifer (either by private well or a municipality) but when treated it may be discharged into a river or ocean. That can create problems because if you’re near the coast, the empty space in the aquifer may be filled by salt/brackish water that can lead to salinity rises in the aquifer. To solve that some places turn to “ground water recharge”, which is just a fancy way of saying “we built a big well to put it back in the aquifer”.

          Increasingly, you’re seeing some places essentially sell their treated water. Santa Rosa CA, for instance, built an entire pipeline that goes from their treatment facility to another municipality to be injected into their groundwater.

          So yes, everywhere treats it, but the final destination makes a difference. Las Vegas (or anyone else on the river) only gets credit for what goes back into the river, so any evaporation etc is a problem. It sounds trivial, but there is a reason those other strategies exist. It essentially doubles every pipe, limits where you can park a treatment plant etc. Vegas also does some great grey water re-use. That essentially means it doesn’t go “back” but can get used many many times, limiting the initial draw.

          Wastewater is funny because it’s far from rocket science, but the numbers to implement any of it get staggering very quickly.

            Wastewater isn’t rocket science. It’s just harder and significantly more important. Every engineering discipline makes fun of the civils, but the fact is none of us are half as critical to modern life as them. Every benefit any of us claim rests on their backs. The flow of electricity is a civil engineering feat, the flow of water to and from our homes, businesses, and farms is a civil engineering feat (and critical to health), as is our transportation networks, our entire constructed environment, and even crazy and weird shit like controlling the location of critical rivers.

              And don’t get me wrong, wastewater has tons of complications. Any plant is operated in equal parts science, engineering, and art. It’s a living, breathing, bioreactor. They’ve each got their own distinct personality.

              I actually thought about going into civil engineering in school, but I ended up really liking Computer Science instead. In high school, I was waffling between being a software patent attorney and a civil engineering attorney, but once I took some CS classes, I decided software patents suck and I really wanted to work with computers.

              I have a lot of respect for our civil engineers. My state is experimenting with a variety of civil engineering stuff, like paints for our highways (should help visibility in crappy winter conditions), alternative grass mixtures to cut water use (less engineering and more horticulture, but whatever), and expanding trains. I kind of wish I was involved with that, but I still really like my job, so I just follow that kind of stuff as a hobby. Bridges, trains, and tunnels rock.
