How so? Intel presented new mobile cpu SKUs but you need the Laptops' AIB s is still used to fab more laptops intel CPU based but 7nm mobile cpu will come in next yearAMD needs to get 7nm for notebooks.
They are like backward from intel.
Intel unveils new nodes to mobile first. AMD unveils new nodes to desktop first.
Laptops already switch TDP depending on what you do. Convertibles switch between cTDPdown and Nominal when you switch from Tablet/Laptop mode. Nothing is special about this Razer.I'm sure the processor will down-clock when idle, so lowering the clock/TDP will just make the processor work for a longer period of time before going idle.
It depends heavily on load and the system. Higher TDP will have worse battery life on higher loads, and in workloads that needs sustained performance. In that case, faster won't help at all, as you'll use the performance to do more work anyway.I think it will have a small effect on battery life, at best. There's even a chance it could lower battery life if doing the work slower keeps other parts of the system active for longer as well.
I'm not arguing why a PC that changes configuration might need to adjust it's thermal load, for example removing your machine from a dock might remove part of the cooling solution, and the device might be otherwise too hot to hold in your hands if the CPU reaches the point of thermal throttling.Laptops already switch TDP depending on what you do.

Actually, if your load is demanding enough, yes it will directly impact your battery life.It doesn't change the amount of work that needs to be done. If a video runs fine in 15W mode because it has low CPU requirements, the computer is going to downclock to the same level in 25W mode so there isn't going to be any difference in efficiency or performance.
I would argue that gaming is usually a bursty workload since it's lightly threaded. How often do modern games realistically get 100% CPU utilization on a laptop like this? A lot of games might fully use 1-4 threads that get bounced around the CPU, and if lowering the TDP lowers the max clockrate that could trade off gaming performance for power consumption which would increase battery life... but the CPU isn't running at it's full power consumption in either case (although it's intel, so it's possibly drawing a lot more power than it's TDP in either case - may not hit it's full boost under a sustained load like that).And usually in those workloads, you can't just translate faster = finishing faster. If you are gaming for example, you won't stop gaming 30% earlier because its that much faster. You'll just play at better performance for the same amount of time.
And there are plenty of workloads that are in between. The only time where TDP doesn't factor in battery life is where its bursty enough that it can idle most of the time. And even that demand is increasing with people running more windows and tabs at the same time and with ever increasing demands brought on by the browsers and the websites themselves.
I'm sorry, but I think your comments need a lot of clarification, with both your points about Intel exceeding TDP specs or that TDP doesn't equal power consumption.And to be clear - TDP is not a measure of how much power the CPU uses, it's a measure of how much heat your cooling system need to dissipate in order to to meet Intel's base clock on all cores. That's why it's a weird idea to make it a user-configurable setting. Especially since Windows already has power settings to passively cool and/or throttle the CPU. Turning off the fans should help efficiency at a fixed amount of work.
Also, in the Razer specifically, they said the gaming oriented version with the GTX 1650 uses the 15W TDP Icelake, while the Mercury White with the Intel Iris Plus graphics uses the 25W TDP Icelake. So it seems to be since its such a small chassis, they are considering system TDP, not just the TDP of the individual components.I would argue that gaming is usually a bursty workload since it's lightly threaded.

Right. Because, like I keep saying, TDP is a thermal design recommendation, not a real spec for power draw. Which is why it's at best a meaningless setting to let the end-user change in a laptop with a fixed thermal design. It's fun to think about but I think we both know the real reason the feature is included is because it ended up being more work to remove it than to keep it in.Point 1: In Desktops, you see a 95W specced CPU consistently using 160W. But Desktops use ridiculously sized heatsinks anyways with far more open room and additional internal case fans to help.
