Asus ZenBook Duo UX8407 convertible review - Intel Panther Lake is a game changer

[Redaktion]

Asus has redesigned its dual-screen ZenBook Duo convertible for 2026, making it better in multiple respects. These include the new Intel Panther Lake processor with more efficient CPU cores and a so much faster iGPU that can just about make the GeForce RTX 4050 irrelevant.

[Very good, but price?]

Very nice to see Panther Lake being 46% (at 35W) to 90% (at 20W) more power efficient than 860M and 890M.

Could you benchmark the Intel Arc B390 on Doom Eternal? I'm curious as to how it would perform at 1800p when injected with XeSS Balanced via Optiscaler.

Amazing work! You've compared 388 with everything but it's direct competitor ryzen 9 370hx. Gpu is literally only interesting thing in the CPU, and amd has no better portative graphics than 890m. (Ai max are not portable cpu with their tdp)

This is a laptop review - please check out our dedicated 388H and B390 analysis articles for more comparisons and everything. Besides, there are simply no convertibles with the HX370/375 available right now, if you really want an apples-to-apples comparison.

Sergey, any idea if you guys will be reviewing the yoga slim 7i aura edition (2026 panther lake) any time soon?

[nice: 128 GB at 128-bit]

The issue I have with this laptop, are only 32 GB solered RAM. Give me at least a 48 GB RAM option. I'm not even asking for a 96 GB RAM option, so that I could host Gpt-Oss-120b or a GLM-4.5-Air quant.

At least Panther Lake supports up to 128 GB RAM, which is nice for a 128-bit wide memory interface APU/SOC.

Up to 128 GB

Which makes it twice, what Strix Halo offers: Strix Halo' memory width is 256 bits wide, but SH supports only up to 128 GB RAM.
