Key takeaways
- GPU tier and resolution target: Match the graphics card to your monitor. An RTX 5070 handles 1440p and entry 4K comfortably, while the RTX 5080 Mobile in the ROG NUC 16 AI is better suited for sustained 4K/120 fps sessions.
- Form factor and desk space: Mini PCs like the ROG NUC and BOSGAME P2 Plus free up desk real estate; the HP OMEN 45L is a full tower that demands roughly 18 inches of clearance but offers superior airflow and upgrade headroom.
- Thunderbolt 4 implementation: Verify the port count and whether the TB4 lane is shared with other USB-C connectors. Dual-LAN units such as the BOSGAME P2 Plus pair TB4 with wired networking for latency-sensitive play.
- Memory and storage ceiling: 32 GB DDR5 is the current sweet spot for gaming; if you edit video or run VMs alongside games, the OMEN 45L with 64 GB or the 2 TB storage variant prevents early upgrades.
- Warranty and support: Look for at least a two-year warranty. The ROG NUC 16 AI ships with a three-year plan, which adds meaningful peace of mind for a premium investment.
What's inside
For most buyers, the ASUS ROG NUC (2025) with Intel Core Ultra 9 and RTX 5070 is the best overall gaming PC with Thunderbolt 4, while the HP OMEN 45L GT22 earns our runner-up spot for those who want a full-tower desktop experience with liquid cooling.
Thunderbolt 4 has become a must-have connectivity standard for gamers who rely on high-speed external storage, eGPUs, and multi-monitor docks, yet very few prebuilt gaming desktops actually include it.

The Best Gaming PCs with Thunderbolt 4s Reviewed
Best Overall: ASUS ROG NUC (2025) – Core Ultra 9 / RTX 5070
This compact powerhouse pairs Intel’s latest Arrow Lake-HX silicon with an RTX 5070 Mobile GPU, 32 GB DDR5, and Thunderbolt 4 in a chassis small enough to mount behind a monitor. It is the ideal pick for gamers who want near-desktop frame rates without dedicating floor space to a tower.
Best Budget: BOSGAME P2 Plus Mini PC – i7 12700H / 32 GB
At a fraction of the cost of dedicated gaming rigs, the BOSGAME P2 Plus delivers a 14-core Alder Lake CPU, 32 GB DDR4, and USB4 with Thunderbolt 4 support. It suits casual and esports gamers who want TB4 connectivity for docks and external drives without breaking the bank.
Best Premium: ASUS ROG NUC 16 AI – Core Ultra 9 290HX Plus / RTX 5080
With an RTX 5080 Mobile GPU, Wi-Fi 7, and a three-year warranty, the ROG NUC 16 AI is engineered for enthusiasts who refuse to compromise on frame rates or future-proofing. The triple-fan cooling solution keeps sustained boosts high during marathon sessions.
Best for High-End Desktop Gaming: HP OMEN 45L GT22 – 64 GB / RTX 5070
The OMEN 45L’s liquid-cooled Core Ultra 9 285K and 64 GB DDR5 make it a natural fit for gamers who also stream or run heavy background workloads. Its full-tower layout leaves room for GPU and storage upgrades down the road.
Best for Content Creators Who Game: HP OMEN 45L GT22 – 2 TB / RTX 5070
The 2 TB NVMe SSD variant of the OMEN 45L is tailored to editors and streamers who juggle large project files alongside AAA game installs. Thunderbolt 4 on the rear I/O lets you daisy-chain fast RAID arrays or a 4K capture dock without opening the case.
Frequently Asked Questions
Does Thunderbolt 4 actually improve gaming performance?
Thunderbolt 4 does not raise in-game frame rates directly, but it enables 40 Gbps external storage, low-latency eGPU enclosures, and single-cable multi-monitor docks that streamline a gaming setup and reduce cable clutter.
Can I use a Thunderbolt 4 eGPU with these PCs?
Yes. All five picks expose at least one Thunderbolt 4 port, which supports external GPU enclosures. Pairing a TB4 eGPU with the BOSGAME P2 Plus or either ROG NUC is a practical way to boost graphics performance later without replacing the entire system.
Is a mini PC sufficient for modern AAA gaming?
A mini PC with a discrete mobile GPU—such as the RTX 5070 in the ROG NUC—handles most AAA titles at 1440p high settings. For native 4K ultra with ray tracing, a full-tower option like the HP OMEN 45L or the ROG NUC 16 AI with an RTX 5080 is the safer bet.
What should I check before buying a prebuilt Thunderbolt 4 gaming PC?
Confirm the exact Thunderbolt 4 port count, whether the port shares bandwidth with other USB-C connections, the system’s upgrade path for RAM and storage, and the included warranty length. Cross-reference the seller’s return policy in case the unit arrives with a DOA port.
Final Thoughts
If you want the strongest balance of size, performance, and Thunderbolt 4 connectivity, the ASUS ROG NUC (2025) remains our top recommendation. Enthusiasts chasing maximum frame rates should look at the ROG NUC 16 AI with its RTX 5080, while the HP OMEN 45L GT22 is the best choice for buyers who prefer a traditional tower with liquid cooling and generous upgrade room. Whichever you choose, Thunderbolt 4 ensures your setup stays ready for the next generation of peripherals.
