Kaby Lake refresh CPUs (i5-8520u, i7-8550u)

johannesg00 · 2017-10-20 05:06:38

Hi,

i consider to buy a new Dell XPS 13 with a Kaby Lake refresh CPU, e.g. an Intel Core i7 8550u.

Does anybody know if there are any issues or if the CPU (and integrated GPU) works fine?

Thanks!

So far, so good on my week old XPS 13 with i7-8550u.

Thanks for your information. Did you notice anything that does not work? And have you tested a USB C/Thunderbolt to HDMI converter?

I've got a HP Envy 13 with the i7 8550u. Works OOTB, no obvious show-stoppers. I've used a USB C to VGA convertor (don't have my HDMI monitor to test with just yet) but the Envy 13 doesn't have thunderbolt.

Of course, the real bugs will take time to show (unoptimal power management perhaps), but nothing I can point out after a week of daily usage.

My struggles are with HiDPI. I do not have any USB C/Thunderbolt to test with. My HiDPI issues have to with VMWare and VirtualBox. My base Arch with KDE is working great. Thus far performance is great and aside from my virtual machine issues, I am very pleased.

Okay, thanks for your informations!

@caskale13c: Do you have the QHD model with touch? And have you tested the wifi and bluetooth card?

Is this the model you are thinking about?

Yes, but the updated model with the Kaby Lake refresh CPUs.

i recently bought asus ux360cak. kaby lake m3-7Y30 lower end processor. using arch/gnome. everything works great except i have problem with vaapi.

Yes, I have the QHD model. I am using both WiFi and bluetooth (mouse) regularly and have not noticed any real issues. I di have some intermittent WiFi slow down early on. I seems to have gone away so I never really even tried to do any problem determination on it.

Thank you! I think i will order the model with a HD display, 16GB RAM and the i7 8550u which was released last friday in Germany.
Did you changed the BIOS settings to AHCI?

Side note, spent some time today undervolting the i7-8550U, and am getting significantly higher sustained core speeds with -110.4 mV undervolting. Stability test still running, but its already been 2 hours of that so don't foresee problems.

Basically it looks like at least on my machine the Kaby Lake R processor throttles on TDP rather than temps (cooling seems pretty good on this HP Envy 13), so undervolting correspondingly has a much greater boost effect.
