Our review of this HP Zbook Ultra G1a features the AMD Strix Halo APU which was announced at CES 2025. Despite its age this is the most powerful APU that money can buy, and both the CPU and graphics are truly impressive. To make things interesting we put the HP laptop head-to-head with Intel’s brand new Panther Lake Core Ultra X9 388H so we could see the best integrated graphics in action.

Testing and Performance

Geekbench 6 Multi Core

In Geekbench 6 Multi Core we see the HP Zbook in an effective tie with the Asus Zenbook Duo and Intel Panther Lake. This indicates that Core Ultra X9 388H has something extra that makes up for the lack of pure CPU grunt.

Cinebench 2026 Multi Core

This is the result we expected in Cinebench 2026 Multi Core with the AMD Strix Halo powering the HP Zbook to a clear victory by a massive margin.

AIDA64 Memory Bandwidth

The HP Zbook  is loaded with a massive 128GB of LPDDR5x-8533 and the Strix Halo has a quad channnel memory controller which combine in AIDA64 Memory Bandwidth to deliver a decisive victory.

Far Cry 6 at 1,280×800 on Ultra Preset

We show a number of gaming tests in our video. This particular test shows a low resolution with the clever image enhancements disabled, and the result is the HP Zbook runs at over 100fps on average which is impressive.

Cyberpunk 2077 at 2,880×1,800 with Frame Generation Enabled

Cyberpunk 2077 is a stiff test for any laptop and 2,880×1,800 is a huge resolution so it comes as quite a surprise to see the HP Zbook using Frame Generation to play at nearly 100fps.

Battery Life

The HP Zbook does well in our battery test and shows that you can work all day on a single battery charge. Having said that, you will want to take the charger with you to guarantee you get maximum performance.

Closing Thoughts

If KitGuru were to invent an award for Most Stealthy and Under Stated Product Ever, the HP Zbook Ultra G1a would make the list and would likely win the award. It looks like a dull, grey 14-inch laptop that is thin and light yet it packs the most amazing punch and delivers epic performance from the AMD Strix Halo APU without any need for add-in graphics.

You may have noticed in our video that we barely discuss operating temperatures and don't mention noise levels at all, and that is for good reason. The innards typically run at 60 degrees C on battery and 70 degrees C on charger, and the cooling system wasn't the least bit intrusive. It is a remarkable laptop that is mainly back by its hefty £3k+ price tag and slightly affected by the annoyingn amount of HP software.

You can buy the HP Zbook Ultra G1a for £3,204 HERE.

Pros:

• Epic CPU and GPU performance from AMD AI Max+ PRO 395.
• Impressive battery life for a mobile workstation.
• Compact form factor that is highly portable.
• Huge memory bandwidth from quad channel DDR5.

Cons:

• Very expensive.
• 3rd party monitoring utilities continue to be confused by AMD APUs.
• HP includes a number of pieces of software instead of a single utility.

KitGuru says: The HP Zbook Ultra G1a is deeply impressive and shows we can live without Nvidia graphics.
