By "throttling" I do mean the CPU falling below its base frequency to protect itself, I don't mean the turbo frequency falling down under load, that's normal and happens even on desktop CPUs with ample cooling.Īs an example - the CPU in the Razer Blade is an i7-8565U, with base speed 1.8GHz, turbo speed 4.6GHz. All intel CPUs have base and turbo speeds, and the turbo speeds usually only apply to a single core or to multiple while there is thermal headroom. Right, let's clarify what I mean by "throttling". I'm just baffled by 1) how can this not be obvious 2) how can it be hard to think of one usecase where that's useful?
IWORD LAPTOP COOLING STATION FULL
My point is - of course there are laptops on the market that are designed for sustained full load and are completely absolutely fine with it. Those are top lines for these brands and they are famous for aggressive throttling under load. But maybe they shouldn't feel too bad - a lot of other companies do mess it up too. It's almost an achievement that they managed to mess this up. And that's a completely normal 15.6" laptop.īut you know what throttles? Laptops like the MacBook Air, where Apple used a Y-series CPU and gave it zero cooling - that will throttle hard after a while. My wife has a Lenovo Y540 - with an i5-9300H, 45W CPU - again, the cooling on it is super beefy and it will run indefinitely at full load. It's just a well designed dual-fan cooling solution. Both the CPU and GPU can be at full load indefinitely and will not throttle. I have a Razer Blade Stealth, 13" laptop where the manufacturer has actually gone against the advice from Intel, and gave the CPU a budget of 25W instead of the advised 15W - and the cooling to work with that. I hope that answers the question of "why would you possibly want to do that". Sure they weigh about 5KG, but that's absolutely fine for the target use. Well, then you need to look a little bit longer around the market.Īt work we use Eurocom laptops with desktop-grade i7 and i9s rated at 90W of power - and we use them for conferences and trade shows to run our demonstrations, they do absolutely fine under full load.
