Dynabook Portégé X40-K, proof of a laptop that is not afraid of the workload

Dynabook Portégé X40-Ka series already known under the name Toshiba Portégé, is a laptop aimed at all those professionals who need it multitasking expensive in terms of material. It’s not a gaming-specific machine, although its hardware could easily put it in that category.

The proof: Dynabook Portégé A30-E, a laptop for business and more

For the benefit of the curious, let’s say right away that it’s an excellent notebook and, during six days of testing, it didn’t reveal any functional weaknesses. Before talking about the hardware, it is good to appreciate the machine externally.

What does he look like

Entirely made of aluminum alloy and on the back of the screen, the laptop appears robust. There backlit keyboard inserted in a solid plane that does not bend even under the application of abnormal pressure keys but which are at a good distance from each other and with a deep stroke.

On left side there are two USB-C ports, one of which is dedicated to power supply, a standard Hdmi output port (with 4K support) and a USB 3.1 port. On right side in addition to an RJ-45 port for ethernet connections up to 1 Gbps, there are two other USB 3.1 ports, one for charging when the computer is turned off, a slot for micro-SD and one for smart cards, in addition to the classic jack sound. The speakers are stereophonic with Dolby technology, have a clear and loud sound beyond what can be expected from a laptop.

Wireless connectivity includes Wi-fi 6 (802.11ax) and Bluetooth protocol version is 5.1.

The hard drive is a 512 Gb Samsung PCIe 3.0 x 4 SSD with a sequential read of 1,811 Mb / s and a sequential write of 1,236 Mb / s.

The screen 14 inches is in Full HD anti-glare, has a resolution of 1920×1080 and is equipped with reliable and smooth touch technology. Equally practical and fluid is the mousepad that supports up to 4 finger movements.

All enclosed in size with dimensions of 323.6 x 220.6 x 17.9 mm and a weight that the manufacturer declares “starting at 1.46 kg”. Security is entrusted to both the fingerprint scanner and Windows Hello Face, facial recognition mediated by the infrared HD webcam.

Processor, Ram and Graphics Component

It should be said that we tested a “sample”, or a computer with less efficient hardware than those that reach the market. Important aspectbecause the laptop we had in our hands is really powerful.

The processor is an Intel Core i7-1260P dating from the first quarter of 2022, equipped with 12 cores and 16 threads, an architecture that deserves a quick study.

It’s actually 4 “performance cores” with 8 threads and 8 “performance cores” with 8 threads. A “performance core” is designed to offer maximum performance and contrasts with “efficient cores” designed for lower but less power-intensive performance. The two different cores have different clock speeds and voltage.

In this particular case we are talking about 4 “performance cores” with a clock speed of 2.1Ghz that increases up to 4.7GHz while the “performance cores” have a base speed of 1.5GHz to 3.4GHz. The bus is 4 gigatransfer per second and the cache is 12 Mb. All respectable equipment.

Tdp (the thermal design power), i.e. the processor’s wattage consumption ranges from 28 to 64 and, even more interestingly, the single thread score, i.e. the workload completed in a certain period of time, displays this processor between better currently on the market. The single thread rating is an important value for all those activities that require CPU usage.

The machine is equipped with 32 Gb Ramsplit into two units of 16 Gb Ddr4 (3200 MHz) while the graphics card is Intel Iris Xe, equipped with 16 Gb of shared Ram memory and which keeps pace with Intel processors from the eleventh generation onwards, returns excellent performance for gaming as well, if and is primarily designed for creativity, multitasking and online collaboration.

The standard equipment

The Dynabook Portégé X40 is designed in three different models, including 12th generation Intel processors i3-1215U, i5-1240P, i7-1260P with 4, 8 or 16 Gb of Ram (expandable up to 32 Gb) and 128 Gb SSDs, 256 Gb or 512 Gb.

The operating system is Windows 11 and the color of the laptop is “Dark Tech Blue”, a dark blue that differentiates it from the more classic gray, dark charcoal or black colors.

Evidence

We have professional use simulation and therefore, considering the high capabilities of the laptop, we took on the role of system administrator by installing VMWare Workstation Pro 16 on which we simulated a Windows 2022 Standard server (Desktop experience) that we have equipped with 8 processors and 8 Gb Ram . After pushing it to the domain controller, we installed two Windows 11 Pro virtual clients to which we allocated 4Gb of Ram that we placed in the newly created domain and to which we distributed software packages (Office and Teams) via Group Policy.

To stay true to the choices a systems engineer would reasonably make, we chose VMWare’s “Side channel mitigations” configuration, which, in exchange for greater security, tends to make virtual machines less efficient.

The laptop held up very well and we were able to write this article naturally smoothly while the server and both virtual clients were running. All this protects against the predictable overheating of the computer equipped with two fans especially silentit always remained cool (despite the heat of those days between late June and early July).

As for the 4-cell Li-ion battery, the duration is important. Using Windows 11 Pro we didn’t need to plug in the power cord for 9 hours and 38 minutes, doing normal tasks like browsing the web, reading and completing this article while listening to low-volume music on Microsoft’s media player.

Using this laptop pays off a smooth and enjoyable experienceno sudden slowdowns even during the workloads we’ve put it through.

Hardware engineering

Above the in recent years it has become more and more common find laptops that don’t have special cases on the back that are designed to be easily removed and you can at least access the hard drive and ram without worry. The same can be said about batteries: once easily removed, today they tend to “disappear” inside the shells.

If powering through the USB-C port responds well in advance to the parameters imposed by Europe from the fall of 2024 (for laptops the deadline starts 16 months after that date), the same cannot be said for the difficulty with which can access the battery and with it the hard drive and RAM. Replacing the battery of any electronic device according to the EU – with an effective date yet to be determined – should be easy and, in the case of this laptop, it is an unfulfilled condition. To do this, it must be opened by splitting the body, an operation for steady and determined hands.

Price and conclusions

The Dynabook Portégé X40-K laptop is an excellent computer that does not force compromises on its user, free to perform traditional tasks while the machine is busy with complex tasks in terms of hardware resources. It will be released at the end of September, starting at €1299 including VAT, in combination with PCs with similar features.
