> If you switched all the CPU-only servers running AI and HPC worldwide to GPU-accelerated systems, you could save a whopping 11 trillion watt-hours of energy a year. That’s like saving the energy more than 1.5 million homes consume in a year.<p>That is a bold claim. It seems to me they simply assume all necessary code would trivially be converted to run on GPUs.
I really like the Noctua cards they're collaborating on, it's not really necessary to go water-cooled once you've got a 4ish slot card/heatsink with quiet 120mm fans!<p><a href="https://noctua.at/en/asus-geforce-rtx-3080-noctua-edition-graphics-card" rel="nofollow">https://noctua.at/en/asus-geforce-rtx-3080-noctua-edition-gr...</a>
Reminds me of the old IBM mainframes (until the 1990s) that were liquid cooled. They had an ingenious approach called TCM (Thermal Conduction Module) with the silicon chips directly attached to a cooled substrate.
This makes very little sense. How exactly does water cooling contribute to power efficiency? Once you get that heat off the chip it has to go somewhere and what is the complexity of running water cooling hoses all over the datacenter. How efficient is it if you get a leak even 1% of the time?
So this saves energy because cooling with water is more efficient than with air.<p>The Data center also needs to add water cooling for all power supplies and chips for maximum efficiency.
Article says closed loop cooling so I imagine it’s just a big scale version of pc cooling but the radiators vent outside. But I wonder if you could pump sea water in to a datacenter and cool using an open loop. Perhaps salt and dirt would become too much of a problem.
Data centers need this for space constraints, but if you're just the average Joe gamer I encourage you to think twice before considering liquid cooling (especially a custom loop).<p>Why do I say this? Because...my goodness, it gets expensive, and you're really not going to get much more performance or even noise reduction out of it (and like...don't you already wear a headset while you game?)<p>I've never understood the market for CPU AIOs especially. They're just so expensive compared to fitting a giant heatsink and fan on there, which will be quite quiet if it's large enough.
Minor, that should be 66% fewer in the chart, not "less".<p>So question, how do these compare in terms of cost against the non liquid variants? I've been buying the Evga Hybrid variants of Nvidia GPUs, and they are not cheap at all, more on the premium side. That's the only cost reference I've got.
Btw: Has someone yet 'fiddeled' out how to add a keyboard directly to the graphics-card ? There are Ports, and RAM...(huge RAM)...so ?<p>OT... (-;
