Question x86 and ARM architectures comparison thread.

MaxTech did some benchmarks with Panther Lake. I will post the relevant screenshots here, so you all don't need listen to the hyper voice every 2 seconds.

Gotta say Intel/AUUS still drops performance on battery by default, probably why it lost in the lightroom test.

People benching nT perf on battery aren't serious and should consider different life decisions.

I mean laptop reviewers do check it to test performance degradation on battery but the 10 minutes test is a bit much.

I'll bite. Why?

I think even if it had been plugged in, it would still have lost the test.

I'll bite. Why?

Two reasons:

• Most people don't run nT-heavy workloads such as rendering on battery, mostly because the battery isn't going to last very long;
• The lightly threaded workloads actually drop much more perf on battery compared to heavy threaded.

Notice how Cinebench nT score drops much less on LNL compared to Cinebench 1t, or Blender compared to Speedometer. So it's not really representative to test nT workloads on battery to draw meaningful conclusions about plugged/on battery perf delta.

It’s not even rendering. Even basic stuff like Lightroom export is slower on battery and that also means video exports will be slower than when plugged in. Most people that buy these laptops will never change the power profiles and but they did pay for performance that they will never get on battery.

It’s why I highlighted it. No one sane is going to be doing rendering on a tiny iGPU in a professional capacity but the Cinebench test highlights how even simple stuff is throttled when it doesn’t need to be.

Speak for yourself. Pretty nice gaming on my patio on my MBP, feet up. Battery lasts nearly all day, even under gaming load.

I've mentioned before that I did a lot of data science in my career. You would be surprised how much of my work was done in conference rooms, on my patio, on airplanes, at conferences, etc. A lot of the reason why people don't run heavy workloads is because Windows laptops suck, not because they don't have a need to run heavy workloads.

Second point is valid. 1T should drop even less compared to nT IMO, not the other way around.

I'm with this comment regarding the use of nT. I agree that no one is running cinememe on the go, but the reason why people don't run stuff (data science etc) on windows laptops is because they can't do it well unplugged. I personally do run heavy stuff on my Windows laptop unplugged, and it frustrates me that I have to plug it in to get the max performance.
