Overview: A Tale of AMD's Strix Halo

At the heart of the HP ZBook Ultra G1a 14 lies AMD's Strix Halo architecture, specifically the Ryzen AI Max Pro 380 processor. This chip features six Zen 5 cores and twelve threads, capable of boosting up to 4.9 GHz. The integrated Radeon 8040S graphics should theoretically provide excellent performance for a mobile workstation of this size.

However, the test configuration we received came equipped with just 16 GB of non-upgradeable LPDDR5X-8333 RAM, with only 4 GB allocated to the iGPU. This decision effectively hamstrings a system that otherwise shows tremendous potential. In today's computing landscape, where memory demands continue to rise, this limitation feels particularly shortsighted.

HP has equipped the ZBook Ultra G1a 14 with a respectable selection of ports:

2x Thunderbolt 4 ports supporting Power Delivery and DisplayPort
2x USB 3.1 Gen2 Type-A ports
1x HDMI output
Audio jack (Line-In/Out)
Kensington lock slot

The inclusion of Thunderbolt 4 is particularly noteworthy, enabling high-speed data transfers up to 40 Gbps and support for multiple external displays. Wi-Fi 7 (Mediatek MT7925) delivers impressive network performance, with our tests showing speeds reaching 2,300 MBit/s in receive tests—significantly outpacing many competitors.

One notable omission is a card reader, which may disappoint photographers and videographers who frequently transfer files from SD cards. The 5 MP webcam, however, produces sharp, detailed images that should satisfy video conferencing needs.

Keyboard and Touchpad: A Comfortable Working Experience

The input devices on the ZBook Ultra G1a 14 reflect HP's experience in the business laptop space. The chiclet-style keyboard features white backlighting with decent key travel and tactile feedback. While it may not match the legendary ThinkPad keyboards, it's certainly comfortable enough for extended typing sessions.

The touchpad measures a generous 12.5 x 8 cm, providing ample space for multi-touch gestures. Its smooth glass surface tracks precisely, and the integrated buttons respond with satisfying clicks.

Display Excellence: OLED Mastery

The display is arguably one of the ZBook Ultra G1a 14's strongest features. The 14-inch OLED panel delivers a stunning visual experience with:

2,880 x 1,800 pixels resolution (243 PPI)
120 Hz refresh rate for smooth motion
Multi-touch support
Near-complete AdobeRGB coverage (97.1%)
99.8% DCI-P3 coverage
100% sRGB coverage
Excellent contrast ratio and true blacks

Color accuracy is outstanding even without calibration, making this display ideal for creative professionals working with color-critical content. Response times are exceptional—our measurements showed 0.69 ms for black-to-white transitions and 0.66 ms for grey-to-grey, placing this panel among the fastest available.

The only real drawbacks are the reflective surface (common to OLEDs) and PWM flickering at 476 Hz, which may affect sensitive users. Brightness averages just under 400 cd/m², which is acceptable though not exceptional.

These results place the SSD in the mid-range of the comparison field, adequate for most workloads though not class-leading.

The Memory Crisis: The System's Achilles' Heel

The most significant limitation of this configuration is its memory subsystem. With just 16 GB of total system memory—split with 4 GB allocated to the Radeon 8040S iGPU—the remaining 12 GB for the CPU and general system tasks is insufficient for many professional workflows.

Why This Matters

Modern integrated GPUs share system memory with the CPU. For the Radeon 8040S to perform optimally, it needs adequate memory bandwidth and capacity. With only 4 GB allocated to graphics, the iGPU becomes severely constrained in memory-intensive tasks and gaming scenarios.

HP's memory allocation strategy (4 GB for iGPU, 12 GB for system) seems to recognize this limitation but fails to address it meaningfully. A more appropriate configuration would have been 32 GB of RAM, with 8-12 GB reserved for graphics duties. The inability to upgrade the memory makes this a permanent limitation—a significant oversight for a device marketed as a mobile workstation.

Performance Impact

The memory configuration directly impacts performance in several ways:

Graphics Performance: The Radeon 8040S underperforms relative to expectations, with the iGPU struggling to deliver smooth frame rates even in moderately demanding games.
System Responsiveness: Our testing revealed that the system doesn't always feel particularly responsive during everyday Windows use, suggesting memory pressure affects overall performance.
Limited Future-Proofing: With 16 GB already becoming marginal for professional workflows, this system has limited longevity for users with demanding workloads.

AMD's Radeon 8040S is faster than previous iGPU frontrunners like the Radeon 890M and Intel's Arc Graphics 140V, but the advantage is modest—and emissions and power consumption under load are noticeably higher.

Gaming and GPU Performance

The Radeon 8040S aims to provide capable integrated graphics in a professional package. In our testing, the performance varies significantly depending on workload:

3DMark Performance Rating

GPU	Performance Rating

Arc B390 (Panther Lake)	49.2 pt
Radeon 8040S (Max Pro 380)	45.1 pt
Radeon 890M	36.6 pt
Arc Graphics 140V	35.4 pt

Gaming Performance (1920x1080 Ultra Settings)

Title	Radeon 8040S	Radeon 8060S	Arc B390
Cyberpunk 2077	33.2 fps	80.7 fps	44.9 fps
Baldur's Gate 3	33.8 fps	99.4 fps	53.5 fps
Dota 2 Reborn	93.1 fps	133.1 fps	97 fps
X-Plane 11.11	45 fps	57.2 fps	42.2 fps

The performance gap between the Radeon 8040S and its more powerful siblings is substantial, particularly in demanding titles like Cyberpunk 2077. While less demanding games like Dota 2 run smoothly at maximum settings, current-generation titles require dropping to 1080p and low detail settings for playable frame rates.

Emissions and Energy: The Heat and Noise Trade-off

Noise Emissions

The ZBook Ultra G1a 14 demonstrates a bipolar personality regarding noise:

Idle: Remains quiet, with fans occasionally switching off entirely (24-26 dB(A))
Load: Can reach up to 48 dB(A), making it clearly audible in quiet environments

The high noise levels under load are a compromise for the performance delivered, though many competing workstations offer better acoustic profiles.
