Quick Answer
Thunderbolt 4 enforces strict baseline specs: guaranteed 40Gbps bandwidth, dual 4K display output, 32Gbps PCIe data tunneling. USB4 40Gbps shares maximum theoretical speed but treats dual monitors and PCIe tunneling as optional features. Implementations vary across PC motherboards. Inspect port labels and vendor specification sheets before buying docks, storage, or cables.
Pros
- Broad AM4 compatibility with Ryzen and 7th Gen A-series/Athlon processors.
- Supports up to 64GB of DDR4 memory for flexible system upgrades.
- Easy Debug LED adds useful troubleshooting support during setup.
- Military Class 4 and Guard-Pro add confidence in board reliability and protection.
Cons
- The provided memory support tops out at DDR4 2667 MHz, which is modest by modern enthusiast standards.
- No onboard wireless features such as Wi-Fi or Bluetooth are listed in the manufacturer listing.
- The feature set is focused on essentials, so it may not suit users seeking premium expansion or overclocking extras.
Overview: The MSI B350M PRO-VD Plus is an AMD AM4 motherboard built for Ryzen and 7th Gen A-series/Athlon processors. It is positioned as a practical, no-frills option for users who want core compatibility and essential build features.
Performance and features: With support for up to 64GB of DDR4 memory at 2667, 2400, or 2133 MHz, it is suited to everyday computing, multitasking, and mainstream gaming. The Easy Debug LED can make troubleshooting simpler, while Military Class 4 and Guard-Pro are aimed at improving durability and protection.
Drawbacks and considerations: The memory support is functional but not especially aggressive, so enthusiasts looking for higher-speed RAM support may prefer a newer platform. The manufacturer specifications also do not list onboard wireless connectivity, so some users may need an add-on solution.
Verdict: This motherboard is a solid fit for budget-conscious AMD builders who value stable essentials, helpful diagnostics, and broad AM4 CPU compatibility over premium extras.

Understanding Thunderbolt 4 vs USB4 40Gbps on PC
Thunderbolt 4 and USB4 40Gbps share the same USB Type-C connector, the same 40 Gbps signaling rate, and a common tunneling architecture. They are not the same specification. USB4, published by the USB Implementers Forum (USB-IF), is a base standard in which most high-end features are optional. Thunderbolt 4, defined and certified by Intel, is a strict superset that turns many of those optional features into mandatory ones. This guide covers the electrical and protocol differences, how to identify what a given PC port supports, and how to select cables and peripherals that meet a defined performance envelope.
What Each Standard Requires
Physical Layer and Link Rate
USB4 Version 1.0 defines two-lane operation over the Type-C connector. Gen 2×2 runs each lane at 10 Gbps for an aggregate 20 Gbps. Gen 3×2 runs each lane at roughly 20.625 Gbps raw for an aggregate of about 40 Gbps. A USB4 port is required to support 20 Gbps. 40 Gbps operation is optional, which is why the label “USB4 40Gbps” is used to separate full-rate ports from 20
