Introduction, Specifications, and Pricing

Alongside the XPS platforms, Dell has several other platforms catering to each market. For the entry-level, Inspiron has held down the fort for many years with standard form factor notebooks and 2-in-1 touchscreen platforms. The latest lineup is the 7420, a platform built on Intel's 12th Gen U series processors.

Specifications

The new Inspiron 14 can be configured on Dell's website in several ways. For this review, our unit was outfitted with the Core i7-1255U, a 2+8 PE design for a complete core thread design of 10/12. It has a boost frequency of 4.7GHz and is paired with 16GB of DDR4.

I/O for this design includes multiple USB-C, SDXC Card readers, HDMI and USB-A. Internally, Wi-Fi is powered by the Intel AX211 chipset offering 6e capabilities to this model.

The display uses the new business 16:10 aspect ratio with a resolution of 1920x1200, touchscreen, and is fully convertible to tablet mode. Additionally, Dell offers the Active Pen to make this a note-taking beast.

The Inspiron 14 7420 pricing in the configuration mentioned above retails at $1049.99.

System/CPU Benchmarks

Cinebench

Cinebench is a long-standing render benchmark that has been heavily relied upon by both Intel and AMD to highlight their newest platforms during unveils. The benchmark has two tests, a single-core workload that will utilize one thread or 1T. There is also a multi-threaded test that uses all threads or nT of a tested CPU.

Multi-thread scored 7712 for the Inspiron, just behind the M1 MacBook Pro.

AIDA64 Memory

The Inspiron had the lowest memory performance of any notebook tested, likely due to its DDR4 3200 going up against DDR5 and DDR4 soldered units that typically run 4200MHz or higher.

BAPCo CrossMark

CrossMarkâ„¢ is an easy-to-run native cross-platform benchmark that measures overall system performance and responsiveness using real-world application models. CrossMarkâ„¢ supports devices running Windows, iOS, and macOS platforms.

Value and Final Thoughts

Value

With value, we take the notebook's performance in several testing areas and put it against the cost at the time of writing. The Inspiron 14 does remarkably well, scoring 98.4% and second to the Ideapad Flex.

Final Thoughts

I have to be honest. I never used an Inspiron platform until this unit landed on my doorstep. Being a 2-in-1, I had an idea of what the notebook would offer, and based on the platform and previous experience with the Ideapad Flex, I had an idea of where the performance would land too. What I wasn't expecting was a high-quality keyboard and touchpad that seemed like they were meant for the XPS lineup, not the entry-level Inspiron 14.

The keyboard's feel is nearly Thinkpad X1-level quality, and it has a fantastic return on each key and perfect ambiance from the backlighting. The trackpad is very smooth with a low tactile click, not perfect, but certainly better than many platforms that run through the lab.

The performance of this system was hit and miss. I did expect the 1255U to outperform the 1235U in the Ideapad, but thermals play a huge role in getting the best performance out of a system, especially when it's low profile. For the Inspiron, it appears it could use a better thermal solution, as the CPU could not maintain its peak boost for any length of time, allowing the weaker 1235U to do better in most scenarios. The Inspiron 14 can be configured with the 1235U, possibly for a more efficient overall build.

Pricing is always hard to justify, though in the month I have had the Inspiron 14 on my desk, Dell.com has dropped the price to $849.99 a few times. So if you are in the market for a 2-in-1 and are looking at the Inspiron, it's only a matter of time before the price drops again. With that, the Inspiron is one of the better overall value notebooks. Based on its performance in office, photo, and video workloads, it's second only to the Ideapad Flex.

If bought during a price drop, it's likely the best of the two platforms.
