The Intel Core Ultra 7 155H Review: Meteor Lake Marks A Fresh Start To Mobile CPUs

The ASUS Zenbook 14 OLED is one of Intel's EVO-certified notebooks, offering plenty of style and substance within the thin 14.9 mm chassis. While ASUS hasn't provided information on what the chassis is built from, it does look and feel like an aluminum chassis, which doesn't feel particularly cheap and looks the part. As with the rest of the chassis on the ASUS Zenbook 14 OLED, the lid is made from the same aluminium-like material, and it looks very stylish with the Ponder Blue color.
At 312.4 x 220.1 x 14.99 mm (W x D x H), it's portable. The inclusion of the 14-inch 2.8K OLED display and a total weight of just 1.28 kg (2.82 lbs) makes it very capable for its size, as well as a very lightweight offering to travel with. For comparison, the Apple MacBook Air 13-inch (M3) weighs just 0.04 kg less.
Opening up the traditional clamshell design, we can see the 14-inch OLED panel dominating the top half, with the keyboard and the centrally located island-style trackpad. The trackpad doesn't have any discrete buttons, and instead is entirely touch-based. The keyboard keys themselves have a shallow key press and combine the cursor arrows with the (Fn) key functionality while offering a subtle white backlight behind the keyboard, making the Zenbook 14 OLED 'pop.' Although ASUS doesn't include a dedicated fingerprint scanner, along the top of the panel's bezel is a 1080p webcam with a privacy shutter with support for Windows Hello, which can be configured to provide IR face recognition without needing a PIN.
Touching on the display, with a 2.8 K (2800 x 1800) OLED panel, it's fair to say that with the brightness turned up, it's very vibrant and colorful, to say the least. The 14-inch display, according to the official specifications, has a peak brightness of 500 nits when using HDR, while it has a 400 nits peak brightness when HDR is turned off. It can cover 100% of the DCI-P3 color gamut, with a 0.2 ms response time. Regarding refresh rate, the panel supports 120 Hz, while ASUS allows users to switch between either 60 Hz or 120 Hz operation. The panel also has a capacitive touch layer, and ASUS includes a stylus within the packaging for this model.
Looking at the I/O on the ASUS Zenbook 14 OLED, ports and connectors are on both sides of the chassis. Focusing on the left side, it offers a single USB 3.2 G1 Type-A port towards the fold. Three ports look like connectors, but these are just ventilation gaps for airflow to escape.
On the right side are two Thunderbolt 4-capable USB Type-C ports, which support external displays and offer USB power delivery (USB-PD) capabilities. The Zenbook 14 OLED doesn't have a dedicated connector for charging, and instead relies on carging through its USB Type-C ports, with ASUS including a 65 W AC Type-C charger in the box. Also on the right-hand side is a single HDMI 2.1 video output and a single 3.5 mm combo audio jack. ASUS includes a USB Type-A to Ethernet adapter in the box, which I haven't seen for a while.
Overall, from looking at and considering the feel of the ASUS Zenbook 14 OLED UX3405MA, it's certainly a quaint premium 14-inch ultrabook. The bottom-mounted Harmon Kardon linear speakers, which don't look much, sound great and are certainly better than typical stock speakers. There's also the 14-inch OLED screen, which looks great and is vibrant and crystal clear, as expected from an OLED panel.
With a price tag (as configured) of $1299, the ASUS Zenbook 14 OLED UX3405MA is certainly a capable offering, which is powered by Intel's latest Core Ultra 7 155H Meteor Lake SoC, but style and design are one element; performance is perhaps the most important element.
ASUS Zenbook 14 OLED UX3405MA: Software
Before we examine the performance, we'll quickly examine the software bundle supplied. Everything on the ASUS Zenbook 14 OLED revolves around the MyASUS software, which acts as a centralized hub for functionality, profiles, updating drivers/software, and customization.
The MyASUS software has many different device settings that users can customize, such as enabling battery care mode, which limits battery charging beyond 80% immediately. Users can also select between three different fan profiles, including performance mode, which maximizes performance, although this does mean the notebook runs very loud. The other options include standard mode, which dynamically adjusts based on the temperatures, and whisper mode, which is very useful for watching moves in bed.
There are also many display-related options, including allocating more system memory to the integrated Arc Xe graphics and different visual profiles to select from depending on the task. Overall, there are plenty of functionalities within the MyASUS software hub, and having it all within a unified piece of software makes things much better for the overall user experience.

Too strange... in the spec2017 test that represents Blender MeteorLake wins but in the real Blender test it loses? GreatDante Verizon - Thursday, April 11, 2024 - link
The iGPU performance of desktop APUs is also abnormally low.Gavin Bonshor - Friday, April 12, 2024 - link
Could you please elaborate? Did another publication's results land higher? Did they run JEDEC memory settings?ballsystemlord - Thursday, April 11, 2024 - link
That near 50% increase in DRAM access latency coupled with the higher thermal limitations is probably what's holding the 115H back.Ryan Smith - Thursday, April 11, 2024 - link
Keep in mind that they're different workloads with different versions of Blender. The version in SPEC2017 is from 7 years ago, which was the Blender 2.7 era.mode_13h - Monday, April 15, 2024 - link
spec2017 is using an old version of Blender that's frozen in time. That's needed to make all spec2017 results comparable with each other.In the individual Rendering benchmarks, Gavin used a reasonably current version of Blender (3.6 is a LTS release from June 27, 2023), probably also built with a different compiler.

"AMD Arc" in GPU specs?Gavin Bonshor - Friday, April 12, 2024 - link
Yeah, that was a really weird one. It has since been corrected.Fozzie - Thursday, April 11, 2024 - link
Why is the text seemingly out of line with the actual results? Repeatedly it is describing wins for the U7 155H that don't seem to be backed up in the actual benchmarks. For example:"As we can see from our rendering results, the Intel Core Ultra 7 155H is very competitive in single-threaded performance and is ahead of AMD's Zen 4 mobile Phoenix-based Ryzen 9 7940HS."
Actually, the graphs don't show a single instance of the Ultra 7155H besting the Ryzen 9 7940HS in ALL of the preceding graphs.
"Looking at performance in our web and office-based testing, in the UL Procyon Office-based tests using Microsoft Office, the Core Ultra 7 155H is actually outperforming the AMD Ryzen 9 7940HS, which is a good win in itself."
How is 6,792 greater than 7,482? How is 6,978 higher than 7,162?
Did the benchmarks get updated after the text was written? Did someone write the summary text and not pay attention to "Higher is better" vs "Lower is better"?

The text describing the Spec tests are also incorrect."Even though the Core Ultra 7 155H is technically an SoC, it remains competitive in the SPECint2017 section of our single-thread testing against the Ryzen 9 7940HS. The AMD chip performs better in two of the tests (525.x264_r and 548.exchange2_r); on the whole, Intel is competitive."
Except the graph shows the AMD system beating the Intel system in 7 tests and only losing by a small margin in 3 of them. The AMD system even beats the Intel desktop system in 4 tests and ties it in 1.
"In the second section of our single-threaded testing, we again see a very competitive showing in SPECfp2017 between the Intel Core Ultra 7 155H and the AMD Ryzen 9 7940HS. The only test we see a major gain for the Ryzen 9 7940HS is in the 503.bwaves_r test, which is a computational fluid dynamics (CFD) simulation."
Except the AMD system wins in 4 tests, essentially ties in 5 tests, and only loses in 2. It even beat the desktop system in 3 tests.
The text is nowhere near consistent with the graphs.
