That last one is more theoretical than practical today. One alternative is to stick datacenters in the ocean. Intel reckons up to 40% of a datacenter's energy consumption goes to the cooling alone (PDF), and it's desperately seeking alternatives to active air and liquid cooling solutions, which largely rely on fans and require lots of juice. Record-breaking supercomputers are being liquid-cooled to ensure they can deal with the heat being thrown out by massively multi-core processors. (Image credit: Future)īut generally demands for heat dispersion are going up, and no place feels the burn more than datacenters and high-performance computing, which is a more boring way of saying supercomputing. Intel's Core i9 13900K is one of the fastest processors ever, but power hungry for it. That's the thing, there are ways around this problem, but they rely on close collaboration between chip designers and chip manufacturers and technology at the bleeding-edge of what's possible. AMD's Ryzen 7 7800X3D, replete with cache, only requires around 80W under load-the benefits of a chiplet architecture that's built on a cutting-edge process node. Not every chip is rubbing up against the power wall just yet. So nowadays we need liquid coolers, or at the very least very large air coolers, to sufficiently cool our chips. To put that into perspective, Intel's best non-X-series desktop chip from 2015 had a TDP (thermal design power) of 91W and would sap around 100W under load. Wattage demands have generally increased over the years-the Core i9 13900KS, a particularly thirsty chip, can ask for 253W from your power supply. We're already seeing that have an effect on how we build gaming PCs. Right now, our answer to that encroaching problem is to deal with the heat being generated by a processor with bigger, better coolers. Or you do with silicon, anyways, and you can read more on that in my article on silicon's expiration date.Ĭlock frequency limited to less than 10GHz by power wall. If you push past that point, you run into problems with dissipating the heat generated from the power surging through the chip at any one time. According to the IEEE's International Roadmap for Devices and Systems 2022 Edition-a yearly report on where the entire semiconductor and computing industry is headed in the future-there's a hard limit on clock speed. You can only assume that a chip in 20 years will exponentially higher clocks and cache sizes. Makes sense, right? Intel has the fastest gaming processor available today at 6GHz with the Core i9 13900KS, and AMD brings the largest 元 cache on the Ryzen 9 7950X3D. "There are a lot of specs that matter in a CPU, but probably the ones that most people look for in gaming are clock speed and cache memory," Moreno explains. It’s hard to think of a CPU that can be an 'all-terrain'. We use a processor for gaming, sure, but video editing, 3D modelling, encoding, running Discord-these are all different workloads and require a deft touch. When it comes to the task we care most about, gaming, a CPU has to be fairly generalist. I like how Carlos Andrés Trasviña Moreno, Software Engineering Coordinator at CETYS Ensenada, puts it to me: "It's hard to think of a CPU that can be an 'all-terrain', since it's very dependent on the task at hand."
