filisterLas Vegas' dystopia-sphere, powered by 150 Nvidia GPUs and drawing up to 28,000,000 watts, is both a testament to the hubris of humanity and an admittedly impressive technical feat | PC Gamer
Todd BonzalezWait, 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 agent, that only accounts for 246 kW, leaving 27709 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 come from needing some intense industrial cooling/airflow stuff in/on the sphere?
empireOfLove2The 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.
