Andrew Marc David

The Precision 7670 is on a higher performance level than previous-generation workstations because of the Intel Core HX-class processor. This chip has a 55-watt processor base power, up from the 45 watts of Intel’s traditional desktop-replacement H-class chips. Dell has had to implement more advanced cooling to handle this chip.

The Precision 7670 also differentiates itself from past Dell mobile workstations with CAMM memory support up to 128GB. (Hit that link for our write-up.) It’s also available with traditional SODIMMs, but those configurations have a 64GB memory ceiling (2x 32GB modules).

Graphics scale from integrated Intel graphics to the NVIDIA RTX A5500 16GB. For those using professional apps, the Precision 7670 has Independent Software Vendor (ISV) certifications. (See the app list.) These certifications are important for industries where accuracy is paramount.

This laptop’s hardware security features are numerous, including TPM 2.0, an optional FIPS fingerprint reader, and encrypted storage drives. It even has chassis intrusion and battery removal detection and other features to prevent tampering. Extensive management features and OOB systems management come from Dell’s Command software suite.

Dell Precision 7670 Build and Design

VIDEO: New Dell Precision 7670 Mobile Workstation Review || Core i7-12850HX RTX A2000
UNBOX ITS

The Precision 7670 keeps its desktop-like power in a rather portable form. It moves to a taller 16-inch, 16:10 aspect ratio screen from the older 15.6-inch, 16:9 standard. Intriguingly, the Precision 7670 comes with either a “thin” or a “performance” chassis depending on the components. Ours is the thin model; it measures 0.98 by 14.02 by 10.18 inches (HWD) and weighs 5.75 pounds. The performance model is about 10 percent thicker, at 1.09 inches, and weighs a touch more (5.9 pounds).

The handsome aluminum chassis is what Dell calls Titan Gray. The build is exceptionally strong; no part of the chassis flexes under pressure, and the lid is impressively stiff. Build quality of this nature is expected (and always appreciated) on premium mobile workstations.

Our review model has the top-shelf OLED display option, with a UHD (3840×2400) resolution. It boasts a productive anti-glare surface and dazzles with a rated 500-nit brightness. Dell rates it for 100% DCI-P3 color gamut coverage. This display is suitable for color-sensitive work if calibrated. The FHD (1920×1080) camera above the display has a privacy shutter and infrared support for biometric logins. You can also log in using the fingerprint reader (with optional FIPS certification).

Dell Precision 7670 Keyboard

Not all 16-inch laptops squeeze in a numeric keypad, let alone a full-size one, but the Precision 7670 does so without a problem. The only layout oddity is the arrow key cluster, which is forced into the main keyboard area. The half-height up and down and full-size right and left keys lead to missed keystrokes; I’d prefer the left and right keys to be half-height, too. Otherwise, the keyboard offers a pleasant typing feel.

White backlighting makes for good contrast in the dark. Below, the full-size buttonless touchpad is nicely sized. The Precision 7670 foregoes the eraser-head pointing stick in the center of the keyboard that was often found on past Precision mobile workstations.

The Precision 7670’s has an abundant port selection as expected on a mobile workstation. On the left edge, you’ll find gigabit Ethernet, HDMI 2.1 video output, USB-A 3.2 with PowerShare, two Thunderbolt 4 (USB-C) ports, and an optional SmartCard reader slot. The power adapter also connects over here.

Dell Precision 7670 Left Ports

The right edge has the remaining ports, including an SD media card reader, an audio combo jack, USB-C 3.2 Gen 2 with DisplayPort, and USB-A 3.2. There’s also a Wedge lock slot. Inside, Wi-Fi 6E and Bluetooth 5.2 come courtesy of an Intel AX211 network card. 5G mobile broadband is optional.

Dell Precision 7670 Right Ports

The Precision 7670 has good upgrade potential. Removing the bottom panel gives you access to the battery, storage, memory, and wireless card. One M.2 2280 Gen 4 slot is centered and the other is left of the battery. When equipped with an NVIDIA RTX A2000 graphics card like our unit, the Precision 7670 does not come with a third M.2 slot.

Dell Precision 7670 CAMM Module

This Precision 7670 has Dell CAMM memory, which is one big piece. It allows this laptop to support 128GB of RAM, double the amount it supports with SODIMMs (64GB). See our in-depth article on the upcoming CAMM standard. Here’s what the module looks like removed.

Dell

Our Precision 7670 review unit is configured as follows:

  • Windows 11 Pro
  • 16-inch OLED UHD (3840×2400) screen
  • Intel Core i7-12850HX processor (16 cores, 24 threads, 2.1 to 4.8GHz)
  • NVIDIA RTX A2000 graphics card w/ 8GB GDDR6 dedicated memory
  • 32GB DDR5-4800 RAM (Dell CAMM module)
  • 2x 512GB Gen 4 SSD in RAID 0
  • 6-cell 83Wh li-ion battery
  • 180-watt power adapter
  • 3-year onsite warranty
  • Price as configured: $4,145

This is a mid-level configuration. The Precision 7670’s starting configuration has a Core i5-12600HX (12 cores, 16 threads) and integrated graphics. The top CPU option is the Core i9-12950HX (16 cores and 24 threads like our Core i7-12850HX, but with slightly higher clocks) and GPU choices top out with the NVIDIA RTX A5500 16GB.

The Lenovo ThinkPad P16 directly competes with the Precision 7670, offering Intel Core HX-class processors and similar features. I configured it at $3,203 on Lenovo.com, which is much less than the Precision 7670, but these are enterprise-grade laptops typically bought in bulk; the prices quoted here are the individual unit prices. Enterprises will get more competitive pricing.

Now for the benchmarks. We are using the HP ZBook Power G8 for comparison. It uses a Core i7-11850H, an NVIDIA RTX A2000 4GB, 64GB of RAM, and a 2TB Gen 4 SSD.

SPECviewperf 2020

Our first test is SPECviewperf 2020, the worldwide standard for measuring graphics performance of professional applications under the OpenGL and Direct X application programming interfaces. The viewsets (or benchmarks) represent graphics content and behavior from actual applications, without having to install the applications themselves. The newest version of this benchmark went through major updates late last year, including new viewsets taken from traces of the latest versions of 3ds Max, Catia, Maya, and Solidworks applications. In addition, they added support within all viewsets for both 2K and 4K resolution displays. The Precision 7670 dominated this testing; its 8GB variant of the RTX A2000 and faster CPU likely gave it the edge over the ZBook’s previous-generation CPU and 4GB RTX A2000.

Viewsets Dell Precision 7670 (Core i7-12850HX, RTX A2000) HP ZBook Power G8 (Core i7-11850H, RTX A2000)

Catia-06 35.85 18.08
Creo-03 59.36 32.61
Energy-03 10.66 7.90
Maya-06 88.54 69.45
Medical-03 10.32 8.19
Snx-04 118.69 92.87
Sw-05 55.43 23.74

SPECworkstation 3

SPECworkstation3 specializes in benchmarks designed for testing all key aspects of workstation performance; it uses over 30 workloads to test CPU, graphics, I/O, and memory bandwidth. The workloads fall into broader categories such as Media and Entertainment, Financial Services, Product Development, Energy, Life Sciences, and General Operations. We are going to list the broad-category results for each, as opposed to the individual workloads. The results are an average of all the individual workloads in each category.

The Precision 7670 continued showing much stronger performance than the ZBook. Only in GeneralOps did the ZBook perform slightly better.

Dell Precision 7670 (Core i7-12850HX, RTX A2000) HP ZBook Power G8 (Core i7-11850H, RTX A2000)
M&E 2.93 2.39
ProdDev 3.66 2.65

FSI 2.88 2.3
Energy 3.58 1.45
GeneralOps 2.19 2.36
GPU Compute 3.32 2.79

ESRI

Next up is the Environmental Systems Research Institute (Esri) benchmark. Esri is a supplier of Geographic Information System (GIS) software. Esri’s Performance Team designed their PerfTool add-in scripts to automatically launch the ArcGIS Pro. This application uses a “ZoomToBookmarks” function to browse various predefined bookmarks and create a log file with all the key data points required to predict the user experience. The script automatically loops the bookmarks three times to account for caching (memory and disk cache). In other words, this benchmark simulates heavy graphical use that one might see through Esri’s ArcGIS Pro software.

The tests consist of three main datasets. Two are 3-D city views of Philadelphia, PA, and Montreal, QC. These city views contain textured 3-D multipatch buildings draped on a terrain model and draped aerial images. The third dataset is a 2-D map view of the Portland, OR region. This data contains detailed information for roads, land use parcels, parks and schools, rivers, lakes, and hill shaded terrain.

The Precision 7670 led the ZBook in every test. As before, this is likely because of its faster CPU and beefier graphics card.

Conclusion

VIDEO: Dell Precision 7670 Overview and Look Inside!
The Broken Tech

The Precision 7670 is an impressive technology platform. Its Intel Core HX-class processors and NVIDIA RTX A-class professional graphics deliver more desktop-like performance than previous-generation mobile workstations. As tested, it’s capable of replacing a desktop for workstation tasks and light 3D work.

The Precision 7670 uniquely brings Dell’s CAMM memory into play. It supports 128GB of memory thanks to that upcoming standard, whereas most 16-inch laptops using SODIMMs only support 64GB. It also offers two or three M.2 Gen 4 storage drives with available RAID and impresses with its aluminum build, 16:10 OLED display, ample port selection, and quality input devices. Overall, the Precision 7670 gets our recommendation for a high-end 16-inch mobile workstation.
