Difference Between HP EliteBook 840 G3 and G4

The HP EliteBook 840 G3 and G4 are two of the most popular laptops in the HP EliteBook G series. They offer similar features, but there are some differences between them that set them apart from each other.

Performance & Components

When it comes to performance, the HP EliteBook 840 G4 has an edge over its predecessor, the G3 model. This is due to the fact that the G4 is a generation younger and offers a better 7th generation processor, as compared to the 6th generation processor in the G3 model.

Furthermore, the G4 boasts a better graphics processing unit (GPU). This means that it has the ability to perform more complex graphical tasks at a faster speed and with greater accuracy than the G3.

In fact, while the G4 may offer slightly better performance, the difference between the 6th and 7th generation processors isn’t significant enough to expect a tremendous improvement in speed. And while the G3 may not have the same powerful GPU as the G4, it still offers solid graphical capabilities.

Both models offer reliable and secure performance, with the G4 offering a slight edge in performance and the G3 providing a solid option at a lower price point.

Overall, the G4 is a winner in terms of performance, with its advanced processor and GPU. It is more capable of handling demanding tasks and running resource-intensive software.

Battery Life

In addition to the differences in performance between the HP EliteBook 840 G3 and G4, there are also some notable distinctions in terms of battery life. One such factor is that the G3 model offers a slightly smaller battery capacity of 46WHr, compared to the 51WHr in the G4 model.

While this difference may not seem significant, it could impact the amount of time you can spend using your laptop on a single charge.

Another important consideration when comparing the battery life of these two models is that the G3 is a year older than the G4.

This means that the battery in the G3 may be more drained due to general wear and tear, compared to the newer battery in the G4. However, it is worth noting that batteries might have been replaced as both models are quite old, so this should not necessarily be a deal-breaker.

It is also important to keep in mind that battery life can be impacted by a variety of factors, including the specific tasks being performed on the laptop, the brightness of the screen, and whether or not any power-saving modes are activated.

Ultimately, both the HP EliteBook 840 G3 and G4 are reliable options for business professionals, with the G4 offering slightly better performance and battery life compared to its predecessor.

USB-C Charging

In addition to the differences already discussed, it is important to note that the HP EliteBook 840 G3 has a USB-C port available. However, unlike the G4 model, this port does not support charging.

This is a notable difference between the two models, as the ability to charge devices through the USB-C port can be a convenient feature for many users.

On the other hand, the G4 model does offer USB-C charging capabilities with up to 15W, which can be a significant advantage for those who frequently use their laptops on-the-go.

With USB-C charging, users can charge their laptops using a compatible charger without the need for a separate power cord. This can help to reduce clutter and improve portability.

While the USB-C port in the G3 model may not support charging, the addition of this port is still a noteworthy feature that sets it apart.


The HP EliteBook 840 G3 and G4 are both great options for business professionals, with the G4 offering slightly better performance and battery life compared to its predecessor. The addition of a USB-C port in the G3 model is also noteworthy, although it does not support charging like the one found on the G4.

Ultimately, each laptop offers reliable performance that can suit different needs depending on your specific requirements. The best laptop for you to buy would be the one on which you can find the best deal.
