Windows 10 Outperforming Linux On A ~$5000 Laptop, Ubuntu Beating Clear Linux

As far as I can tell, this Xeon-E Coffee Lake is identical to the Intel Core i9-9980HK

almost..According to https://en.wikichip.org/wiki/intel/xeon_e/e-2286m it has intel vpro, ecc and TDP can be scaled down to 35W

This is pretty interesting. I'm wondering how it would compare to Win10 Pro with NTFS. I'm assuming additional support for CPUs with high core counts, and the new file system make a huge difference.

I'd be interested to see what the results look like with mitigations turned off.

Without data about mitigations on Windows it doesn't tell much. Clear Linux losing it's another strange thing. CPU governor scaling problems?

Looking for this?

Buy this laptop if you want your bits flipped the fastest via Rowhammer.


Of coarse I am only joking.

This probably is a thermal management issue, where the BIOS is configuring the CPU for a low TPD and relying on Windows to dynamically update the TPD depending on various factors including e.g. accelerometer readings which are used to detect if the laptop is on a lap (underside must not get too hot) or on a table (underside may get somewhat hotter).

Michael, it would be good if you can run one of the benchmarks with a considerable difference between Windows and Linux on battery, while monitoring the power-consumption from the battery with e.g. powertop under Linux and something similar under Windows. Or you could look at the wall-outlet power when fully charged, so the only power consumed is the one directly used for processing. I would not be surprised if under Windows significantly more power is being drawn.

What might also be fun is putting the laptop on your lap while running a (short running) benchmark under Windows and moving your knees up and down a bit (to make sure it detects it is on a lap) this might reduce the Windows benchmark results ...

Yes. Speculative store bypass is disabled. I'm not sure about Ubuntu.

My bad, I was looking at CPU-World.

Trusted Execution is missing in the i9 but present in the Xeon.

They didn't differentiate on RAM at ECC but it makes sense being a Xeon.

LPDDR3-2133, DDR4-2666

All I have else to say is that is one deep, thick and serious looking laptop.
