KitGuru started strongly with Intel Panther Lake when we reviewed the 2026 version of Asus Zenbook Duo, however the price was rather steep at £2,500. Today we are reviewing an MSI Prestige that should offer most of the performance we saw in the Zenbook Duo while simultaneously saving £1,000 on the cost. That sounds amazing!

Performance and Testing

Geekbench 6 Multi Core

In Geekbench 6 Multi Core the MSI does a decent job and is only a few percent behind the new Zenbook Duo and hugely expensive HP Zbook Ultra G1a. This gives us confidence the Intel Core Ultra X7 358H has decent all-round performance.

Cinebench 2026 Multi Core

Cinebench 2026 Multi Core shows the difference between the Core Ultra X9 388H and Core Ultra X7 358H, which boils down to power draw and clock speed. The Core Ultra X7 in the MSI does a good job but the Core Ultra X9 is more impressive.

Assassin's Creed Mirage at 1,920×1,200 with XeSS Frame Generation

We show a few gaming graphs in our video but this one of Assassin's Creed Mirage at 1,920×1,200 with XeSS Frame Generation tells an important tale. The Asus Zenbook Duo with Core Ultra X9 sneaks past the 60fps mark to deliver a tolerable gaming experience while the MSI cannot quite make it to 50fps. When you consider these two laptops have the same number of CPU cores and the same graphics, we can see the importance of power and clock speed.

Battery Life

Intel has done a superb job with the battery life of their new Panther Lake laptop chips. The MSI impressed us hugely when the battery kept going and going, nearly matching the Zenbook Duo which comes equipped with two batteries.

Closing Thoughts

The MSI Prestige 14 AI+ is a conventional 14-inch laptop that is pleasingly thin and light. The main point of interest is the brand new Intel Core Ultra X7 358H processor with B390 graphics, and as we explain in our video this is very close to the top tier of Panther Lake silicon. It came as something of a surprise in our testing when we saw the impact of lower power draw and lower clock speeds that differentiate the Core Ultra X7 from Core Ultra X9.

One area of unalloyed good news is the battery life which runs for more than 22 hours of solid work. If you just want to watch videos we are confident it will last two days, this means you could take the laptop on a short holiday and leave the charger at home. The other features of the MSI Prestige 14 AI+ are all fine, which means our major gripe is that we expect this laptop will sell for more than £1,500.

We estimate the MSI Prestige 14 AI+ will sell for £1,550 inc VAT.

Pros

• Excellent battery life.
• Slender and lightweight chassis.
• Decent performance and a healthy improvement over Core Ultra 200.

Cons

• The OLED screen is adequate but unimpressive.
• Ports and connectors are rather close together.
• The price is fairly steep for a thin and light laptop.

KitGuru says: The MSI Prestige 14 AI+ is a decent everyday laptop that struggles when it comes to gaming.

We first saw the new Intel Panther Lake laptop chip in action at their event in Arizona last October, and today we can review the finished result. This 2026 Asus Zenbook Duo packs the most grunty Panther Lake of them all, the Core Ultra X9 388H. The hardware includes 16 CPU cores and 12 Xe3 graphics cores but the headline feature is the Duo part of the name which refers to the dual 14-inch OLED screens. As you will see, it is pretty nifty.

Testing and Performance

Geekbench 6 Multi Core

in Geekbench 6 Multi Core we see the Asus Zenbook Duo performing well, with the Intel Core Ultra X9 388H some 30% ahead of the previous Core Ultra 9 285H.

Cinebennch 2026 Multi Core

It is a slightly different story in Cinebench 2026 Multi Core where we again see the new Intel Panther Lake wreck the previous Lunar Lake, however the top honours go to AMD with the mighty Strix Halo in the HP Zbook Ultra G1a.

Cinebench 2026 Multi Core points per Watt

Our Cinebench 2026 power efficiency calculation shows the amazing efficiency of Intel's new Core Ultra X9 388H which has good performance and very low power draw.

Far Cry 6 at 2,880×1,800 with FSR Performance Mode

In Far Cry 6 at the massive resolution of 2,880×1,800 running on the Ultra preset we used the FSR Performance Mode and saw average frame rates north of 70fps. This is remarkable performance from Intel's latest iGPU and it looks great on the Asus OLED screen.

Cyberpunk 2077 at 1,920×1,200 with Frame Gen Enabled

Cyberpunk 2077 is a stiff test with the Ultra preset, but running at 1,920×1,200 with Frame Gen Enabled we saw excellent frame rates from the Asus Zenbook Duo. Having said that, the HP Zbook Ultra G1a smashed it out of the park.

Battery Life

Battery life is a critical aspect of a laptop and the new Zenbook Duo does monumentally well, running for just under 24 hours. This is a superb testament to both Asus and Intel.

Closing Thoughts

The changes made by Asus to the 2026 version of Zenbook Duo are very good and we love the way the dual OLED screens almost merge into one display. As an added bonus the 2026 laptop is notably more compact than previous versions, and this approach to packing two full sized 14-inch displays into a fairly regular laptop demonstrates some impressive engineering by Asus.

The new Intel Core Ultra X9 388H is an impressive piece of silicon and our first impressions mark the Intel 18A process as a success. The CPU part of the chip has decent performance and requires very little power. In addition the 12x Xe3 graphics core delivers sufficient performance for daily use as well as serious gaming sessions.

You can buy the Asus Zenbook Duo UX8407A for £2,499.99 HERE

Pros:

• The dual 14-inch OLED screens are superb.
• Battery life is monumental.
• Intel 12x Xe3 graphics are impressive.
• Intel Panther Lake CPU is good.

Cons:

• Zenbook Duo is somewhat chunky and slightly heavy.
• Price is high.
• Ports and connectors are rather close together.

KitGuru says: The latest version of Asus Zenbook Duo comes with Intel Core Ultra X9 and delivers a superb experience.
