For a premium, relatively portable 16-inch workstation, consider the Lenovo ThinkPad P1 Gen 7. Choose the ThinkPad P16 when sustained engineering performance matters more than minimizing carry weight, the HP ZBook X G1i if you want to stay in HP’s ZBook ecosystem, or the Dell Precision 5490 if a 14-inch footprint is your priority. The ZBook Ultra G3a is a 16-inch mobile workstation, so these alternatives cover both comparable 16-inch systems and a smaller option. The right choice depends on the exact processor, graphics, memory, display and service configuration available in your region—not just the model name.
Which ZBook Ultra G3a alternative fits your priorities?
Start with the work you need the laptop to do and how often you carry it. There is no standardized, identical-configuration benchmark in the available product information to establish a single performance winner across these systems. Treat the picks below as use-case matches, then compare the configurations you can actually buy.
- Choose the ThinkPad P1 Gen 7 if you want a premium 16-inch workstation with a relatively thin chassis, business support and workstation software compatibility.
- Choose the ThinkPad P16 if sustained CPU and GPU output takes precedence over minimum carry weight.
- Choose the HP ZBook X G1i if HP’s ZBook support and fleet-management ecosystem are important to your organisation.
- Choose the Dell Precision 5490 if your main goal is a workstation in a 14-inch footprint.
HP’s 2026 support specification identifies the ZBook Ultra G3a as a 16-inch mobile workstation. That makes the 16-inch P1, P16 and ZBook X G1i the closest size-class comparisons in this group; the Precision 5490 is the smaller-footprint alternative.
How the four alternatives compare
The table separates published specifications from details that need to be confirmed for the particular configuration. A model family can offer materially different processors, graphics, displays and service terms; do not assume one configuration’s specifications apply to every unit sold under the same name.
#1 Best Overall
- 【Strong Adsorption】The inspiration of the silicone phone suction case comes from the adhesive force of the octopus. Each suction cup phone mount is 3.15 inches long and 2.17 inches wide, with 24 independent suction cups providing a stronger and more stable suction force, so you don't have to worry about your phone falling during use.
- 【Back of Phone Suction Grip】Remove the adhesive film on the phone suction cup and stick it on the phone case. You can then fix the phone on any smooth surface, which is very convenient. (The phone suction cup cannot be removed and reused after being attached to the phone case. It is recommended to attach it to a regular phone case, not a valuable one.)
- 【Widely Used】Our non-slip silicone phone sticky grip mount attaches to almost any flat phone case and make it compatible with common mobile phones such as iPhone and Android.You can shoot, watch videos or video calls in the kitchen, gym, dance studio, bathroom and other places.
- 【Capture the Wonderful Picture】Whether you are a TikTok creator or just like to share videos and photos, this phone suction cup can help you hands-free capture wonderful videos and photos for sharing with friends.
- 【Note】You can fix the phone suction cup on a smooth surface such as a mirror or glass. If necessary, wipe the suction cup with a damp cloth to obtain stronger suction. Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)

These figures come from the manufacturers’ cited product pages and brochure, not from a shared test setup. Core counts, processor generations and graphics labels alone do not establish which laptop will finish a particular CAD or rendering job faster.
Lenovo ThinkPad P1 Gen 7: a portability-focused 16-inch option
The P1 Gen 7 is the closest match here for someone who wants a premium 16-inch workstation without making sustained maximum output the sole buying criterion. Lenovo describes the model as a 16-inch mobile workstation, and its product page lists configurations with an Intel Core Ultra 7 165H vPro processor. The listed processor has 16 cores and 22 threads.
Those processor details identify an available option; they do not tell you which graphics configuration, display, memory capacity or support package comes with the specific unit you are considering. Lenovo’s product information points to a configuration-dependent comparison, so check the full specification and service terms rather than treating “P1 Gen 7” as one fixed build.

- Compare the exact GPU and memory configuration against the requirements of your engineering or creative applications.
- Check display resolution and service coverage for the region and seller where you plan to buy.
Lenovo ThinkPad P16: favor sustained output over minimum carry weight
Lenovo positions the P16 as a redesigned workhorse mobile workstation in a portable 16-inch size. Its published dimensions—30.23 mm × 364 mm × 266 mm—give a concrete sense of its chassis, but they are not a weight figure and do not establish how it compares in mass with the other models.
Lenovo lists a 12th Generation Intel Core i9-12950HX option with 16 cores and 24 threads. That is a specific processor option, not evidence that every P16 has it or that the P16 will outperform another laptop in every workload. The reason to put this model on your shortlist is its workhorse positioning when sustained CPU and GPU output matters more than carrying the smallest or lightest possible system.
Before choosing, check the processor and graphics in the exact build and consider the demands of your longest workloads. The available manufacturer information does not provide an identical-configuration render or CAD benchmark against the P1, ZBook X G1i, Precision 5490 or ZBook Ultra G3a.

HP ZBook X G1i: retain the ZBook ecosystem
The ZBook X G1i is the practical alternative if your organisation values HP’s ZBook support and fleet-management ecosystem but does not require the Ultra branding. It is a 16-inch option, so it remains in the same broad size class as the ZBook Ultra G3a.

Dell Precision 5490: choose the 14-inch route
The Precision 5490 is the clearest choice in this group when reducing the screen size and footprint is the priority. Dell’s 2024 Precision family brochure calls it an “ultra-mobile 14” workstation” and lists 45 W Intel Core Ultra processors and graphics options up to NVIDIA RTX 3000.
“Up to” describes the top of a product family’s offering, not the contents of every configuration. Verify the GPU, memory and display offered in your market, and make sure the selected unit meets the requirements of your software and workload. The brochure does not establish that every regional configuration includes the same options.

What to check in a workstation configuration
Model names are a starting point, not a complete specification. Compare the following for the exact configurations you can buy; the manufacturer material cited here does not provide a standardized cross-brand test or a complete, like-for-like set of figures for every category.
- Workload and sustained performance: Match the processor and GPU to the applications and project sizes you use. For long renders or engineering jobs, seek comparable results for the exact configurations and workload rather than inferring a winner from core counts.
- Software and GPU support: Check the requirements of your CAD, visualization or other professional applications, including any need for certified graphics or software support. The cited material does not identify a universal certification status for every configuration.
- Memory and storage: Confirm capacity and whether the components can be upgraded in the exact model and build. The cited product details do not establish upgradeability across these families.
- Display: Compare resolution and the characteristics your work requires, such as gamut and brightness. The ZBook X G1i’s 3840 × 2400, 120 Hz, 500-nit, 100% DCI-P3 panel is one listed option, not a shared baseline for this comparison.
- Ports and networking: Check the actual unit’s port selection against your peripherals and office setup. HP lists gigabit Ethernet for the ZBook X G1i; do not assume the same port arrangement across models.
- Mobility: Compare exact dimensions and weight, not just screen size or labels such as “portable.” The cited figures give dimensions for the P16 but do not provide a complete cross-model weight comparison.
- Battery and service: Look for battery capacity and runtime measured under comparable conditions, and review warranty and enterprise service terms for your region. The cited product information does not establish standardized battery-runtime results or equivalent service coverage.
How to make the final choice
- Set the size class. If you want a 16-inch system like the ZBook Ultra G3a, focus first on the ThinkPad P1 Gen 7, ThinkPad P16 and ZBook X G1i. If a 14-inch footprint is a key requirement, put the Precision 5490 on the shortlist.
- Decide whether portability or sustained output comes first. The P1 Gen 7 is the portability-focused premium pick; the P16 is the workhorse choice when minimum carry weight is less important. Treat these as use-case distinctions, not measured rankings.
- Match the configuration to the software. Verify the processor, GPU and memory in the exact unit, then check whether your applications require particular graphics or software support.
- Inspect the display, ports and service terms. Confirm the selected panel, connections and warranty or enterprise support rather than assuming the family name guarantees them.
- Check regional availability and pricing. Product configurations and availability vary by market. Confirm the local specification and price for the actual model or part number before comparing offers.
The manufacturer information cited for these systems does not provide a uniform set of current regional prices, weights, battery-runtime tests or cross-brand benchmark results. Those details should be established for the specific configurations on sale rather than inferred from the model families.
