Review of the Infinix Zero Book Ultra: Breaking into the big leagues

The Infinix Zero Book Ultra is powered by an Intel Core i9-12900H processor and has a unibody metal construction. But is it as good as advertised? Discover more in our review…

Infinix is primarily recognised for its inexpensive smartphones. In 2022, the brand entered the laptop market with the introduction of the InBook line of computers. Now, the business has unveiled its most powerful laptop, the Infinix Zero Book Ultra, which is powered by up to 12th-generation Intel Core processors.

I have been using the Core i9-12900H variant of the Zero Book Ultra as my regular laptop for the past few weeks, and here is my impression of Infinix’s priciest and most potent laptop.

Infinix Zero Book Ultra is a 15-inch laptop that I have just evaluated and found to be attractive. We cannot dispute that this laptop’s design was heavily influenced by the MacBook Pro, but I don’t see a problem with it. The laptop’s metal unibody construction gives it a premium feel. Nonetheless, the Zero Book Ultra weights 1.9 kilogrammes, which, by modern standards, makes it somewhat weighty. The hinge should have been slightly more rigid.

In terms of connectivity, the 15-inch notebook features everything one would expect, including two USB Type-C connections (with support for PD charging), a full-sized HDMI 1.4 port (up to 4K at 24Hz or 1080p at up to 120Hz), a microSD card slot, and a barrel-shaped charging port.

Due to the outdated HDMI protocol, this laptop cannot be paired with a high-resolution, high-refresh-rate display. In general, the fingerprint sensor on the laptop is functional. Likewise, the device is equipped with a physical switch to toggle between power modes. The only thing lacking from this laptop is an RJ45 ethernet connector, which would have made it independent of dongles/adapters.

Infinix appears to have spared no expense in the display department. The gadget includes a 1920x1080p 60Hz display with a peak brightness of 400nits, 100 percent sRGB coverage, and 72 percent NTSC coverage, making this a fairly color-accurate screen for everyday use and media viewing. Again, the display’s black bezels remind me of the MacBook Pro. This screen is glossy; therefore, it reflects a great deal of light.

The Infinix Zero Book Ultra boasts one of the largest trackpads I’ve encountered on a Windows laptop in this category. It is compatible with all Windows gestures and operates as intended. Unfortunately, the keyboard’s keys felt somewhat soft, and I would have like slightly firmer keys. With two levels of keyboard lighting, the laptop can be operated without difficulty in low-light environments.

The Infinix Zero Book Ultra offers a 2.1MP 1080p web camera, which, although not the finest web camera I’ve experienced on a laptop, is certainly above average and suitable for online classes and office meetings. The camera application also includes software with capabilities like as face tracking, background blurring, and a beauty mode that smooths the skin.

The speaker-like grills on either side of the keyboard captivated me when I initially opened this laptop. While having quad-array speakers, this laptop’s audio is not particularly spectacular, especially considering its price of almost Rs 90,000. In fact, the speakers on my decade-old MacBook Pro are somewhat superior to those on the Infinix Zero Book Ultra. While I was able to raise the volume by using the FxSound software, I would have like somewhat more powerful speakers, perhaps with Dolby Atmos capability, for a more immersive video consumption experience.

For the past two weeks, the Infinix Zero Book Ultra has been my everyday driver. While it is powered by a 12th-generation Intel Core i9-12900H processor with Iris Xp graphics, 16GB of DDR4 RAM, and a 512GB PCIe Gen4 solid-state drive, I did not encounter any performance concerns during my testing. Nota bene: This processor is commonly seen in gaming laptops that cost more than Rs 1,000,000 and include a dedicated graphics unit.

The laptop scored 2517 and 12859 points on the single-core and multi-core CPU tests, respectively, on the Geekbench 6 benchmark. Similarly, the laptop received 16730 points on the OpenCL GPU test. Note that this laptop lacks a dedicated GPU, and while it is possible to play games on it at 720p resolution and low graphics settings, if gaming is your top priority you should consider purchasing a device with a dedicated GPU in this price range.

Also, there is a red light at the hinge that can be activated when the laptop is in overboost mode, in which the CPU receives up to 54W of power for better multi-core performance. And the only time I heard this laptop’s fans spinning was when I performed benchmarks. Despite having a 14-core CPU designed for gaming, the notebook operates rather cool.

I mostly utilised this laptop for research, Internet browsing, and content creation, and a single charge would easily last over six hours. Note that I primarily used this laptop in economy mode and that its battery has a capacity of 70Wh. Using this laptop in balanced and over-boost mode will increase its power consumption and reduce its battery life. Even though it supports rapid charging via a USB Type-C connector, the laptop arrived with a barrel-shaped charger, which is unfortunate.

As this laptop features a hybrid CPU with a combination of P-cores and E-cores as well as thread director technology, it assigns low-powered cores to basic tasks such as web browsing and content consumption, while assigning P-cores for processing an image or a video.

At Rs 87,267, the Infinix Zero Book Ultra appears to be an excellent value for those seeking a CPU-intensive laptop with superior all-metal construction, a bright display, and all-day battery life. Note, however, that for an additional Rs 5,000, you can purchase the same laptop with 32GB RAM and 1TB of internal storage. If you intend to get this laptop, I strongly advise you to pay Rs 5,000 more on the superior model.
