Why VPN Speed Matters for 4K Streaming
Streaming in 4K requires a fast and stable internet connection. Without a VPN, you might get decent speeds, but your privacy is exposed. When you use a VPN, your data is encrypted and routed through a remote server, which can sometimes slow things down. The best VPNs minimize this impact, giving you strong security without sacrificing performance. For buffer-free 4K video, you need a VPN that offers high-speed servers optimized for streaming.
Our Testing Methodology
We conducted multiple speed tests over a week, using a 100 Mbps base connection. Tests were performed at different times of day across servers in the US, UK, Germany, and Japan. We measured download and upload speeds, latency, and performance consistency. Each VPN was tested while streaming 4K content on Netflix, Disney+, and Amazon Prime Video to evaluate real-world usability.
Tools and Metrics Used
We used Ookla’s Speedtest tool to record download and upload speeds in Mbps, and measured latency in milliseconds. To assess streaming performance, we checked for resolution drops, buffering, and time-to-load for 4K videos. Each test was repeated three times to ensure accuracy, and averages are reported here.
NordVPN Speed Test Results
NordVPN delivered impressive speeds in our tests, averaging 85 Mbps download speeds on nearby servers. During 4K streaming, it maintained a stable connection with no buffering on Netflix and Disney+. Its proprietary NordLynx protocol (based on WireGuard) clearly contributes to its performance, offering a great blend of speed and security. Distant servers, like Japan from the US, saw a drop to around 60 Mbps, which is still sufficient for 4K streaming.
If you want a fast, reliable VPN that won’t interrupt your movie night, try NordVPN risk-free with its 30-day money-back guarantee.
ExpressVPN Speed Test Results
ExpressVPN also performed exceptionally well, with average download speeds of 82 Mbps on local servers. Its Lightway protocol is designed for speed and efficiency, making it a strong contender for streaming. We experienced instant 4K loading on Amazon Prime Video and consistent performance across all tested locations. Even long-distance connections remained stable, with speeds rarely dipping below 55 Mbps.
For those who prioritize both speed and ease of use, ExpressVPN is a top-tier choice that excels in unblocking geo-restricted content.
Side-by-Side Comparison
Here’s a quick overview of how NordVPN and ExpressVPN stacked up in our tests:
| Metric | NordVPN | ExpressVPN |
|---|---|---|
| Average Download Speed | 85 Mbps | 82 Mbps |
| Average Upload Speed | 78 Mbps | 76 Mbps |
| Latency (ms) | 22 ms | 25 ms |
| 4K Streaming Performance | Excellent | Excellent |
Which VPN Is Better for 4K Streaming?
Both NordVPN and ExpressVPN are excellent choices, but there are subtle differences. NordVPN’s NordLynx protocol gives it a slight edge in raw speed, especially on nearby servers. It’s also more affordable, making it a great value pick. ExpressVPN, with its Lightway protocol, offers incredibly consistent speeds across long distances and is easier to set up for beginners. If you stream international content frequently, ExpressVPN’s reliability might win you over.
Ultimately, your choice depends on your priorities: raw speed and value (NordVPN) or consistency and user-friendliness (ExpressVPN).
