Key Features

• Intel Core i7-8650U (Whiskey Lake, 8th Gen): 4 cores, 8 threads, up to 4.2GHz turbo — a strong performer for the Latitude 7x90 generation delivering responsive business performance post-installation.
• 16GB LPDDR3 on-board: Memory soldered directly to the board — no slots to manage during installation, and generous headroom for multitasking workloads.
• Intel UHD Graphics 620: Reliable integrated GPU supporting dual external displays and smooth video playback for business presentations and video conferencing.
• Thunderbolt 3 (dual ports): USB-C TB3 at 40Gbps with Power Delivery and DisplayPort Alt mode — single-cable docking compatible with TB3 and USB-C docks.
• Wi-Fi 5 (Intel 8265): 802.11ac dual-band wireless for reliable connectivity across standard business network environments.
• Enterprise security: TPM 2.0, Dell ControlVault, smart-card reader interface, and vPro optional — full corporate compliance support.

After-Installation Performance

The i7-8650U delivers a meaningful performance level for the Latitude 7290 and 7390 chassis — fast enough for Microsoft 365, web browsing, video calls, data analysis, and standard business software running simultaneously. The vPro-enabled variant (where applicable) supports Intel AMT for remote management, making it suitable for enterprise IT environments managing large fleets.

The 16GB LPDDR3 running in dual-channel configuration provides solid memory bandwidth for both the CPU and the Intel UHD 620 integrated graphics. Both Thunderbolt 3 ports support simultaneous operation for dual-display docking or high-speed storage — useful for IT technicians and analysts who rely on external display setups.

Reboot IT tests all integrated components before grading: both Thunderbolt 3 ports (data, video, and power delivery), USB-A ports, HDMI output, Wi-Fi antenna connections, audio codec, TPM state, and firmware integrity. The board ships ready to install with confidence.

Frequently Asked Questions

Will this board fit the Latitude 7390 2-in-1?

No — the 7390 2-in-1 uses a different motherboard with different connector layout and thermal design. This MXW44 board fits the standard 7290 and 7390 clamshell models (P29S) only.

Can I upgrade the RAM after installation?

No — the 16GB LPDDR3 is soldered directly to the board and cannot be upgraded after manufacture. The 16GB configuration is sufficient for all typical business workloads on this platform.

What SSD form factor does this board use?

The M.2 slot uses the 2280 form factor and supports both PCIe NVMe and SATA-based M.2 drives. Most Dell Latitude 7390 SSDs are 2280 NVMe.

What testing has been performed on this board?

Reboot IT verifies processor performance, memory stability, both Thunderbolt 3 ports, USB-A ports, HDMI output, Wi-Fi antenna connections, and TPM/firmware integrity before grading and shipping.
