Dell Precision 3551 Laptop Review: Intel Core i9-10885H Debut
Unlike the Precision 3550 which runs on slower Intel U-class series CPUs with optional Quadro P520 graphics, the Precision 3551 bumps up the performance factor with Core H-class CPUs and the optional Quadro P620 GPU. The laptop is an entry-level mobile workstation sitting below the mid-range Precision 5000 series and top-end Precision 7000 series.

Case
The chassis is rotund by today's standards where sharp and sleek designs are common. Edges and corners are rounded for an old-school look and feel despite the narrow side bezels and size reduction when compared to the older Precision 3530. This is all intentional, of course, as users will have to consider the pricier Precision 5000 or 7000 series if they want more visually appealing workstations.

Accessories and Warranty
There are no extra accessories in the box other than the AC adapter and paperwork. Users can choose between a USB-C or the barrel charger if purchased directly from Dell.
The standard limited warranty is only one year as opposed to three years for the Precision 7000 series. This is definitely a cost-saving measure since the Precision 3000 series is targeting budget users.
Input Devices
Display
Dell utilizes the same LG Philips 156WFD 1080p IPS panel for both its Precision 3551 and Latitude 5500. Though contrast is good at almost 1000:1, other characteristics like brightness, response times, and colors are average at best to represent a budget display. This is definitely not the panel option you want if color accuracy is vital. Luckily, the system can be configured with higher-end display options that promise full sRGB coverage if desired.

The display is decently calibrated out of the box with a color temperature leaning on the cool side. Our calibration fixes this, but colors remain average at best due to the limited color space mentioned above.

Performance
Processor
CPU performance is almost 20 percent slower than the non-vPro-enabled Core i7-10875H in the Precision 5550 according to CineBench benchmarks. Raw performance is nonetheless almost 1.5x faster than the Precision 3550 if it were configured with the Core i7-10510U.
See our dedicated page on the Core i9-10885H for more technical information and benchmarks. Our unit was set to Ultra Performance mode via the Dell Power Manager software prior to running these benchmarks.
(October 16, 2020 update: Dell has confirmed that the Precision 3551 uses a 35 W CPU design while the Latitude 7550 is a 45 W design which explains why our Core i9 Precision can perform slower in multi-threaded workloads than a Core i7 Latitude.)
