Independent testing
How much independent testing exists for each streaming device
Of the 8 streaming devices we track, 6 have been physically measured by at least one independent lab. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| Roku Streaming Stick 4K | 2 | 8 | 2 |
| Amazon Fire TV Stick 4K Max (2nd Gen) | 2 | 6 | 4 |
| Roku Ultra (2024) | 2 | 4 | 3 |
| Apple TV 4K (3rd Gen) | 1 | 5 | 4 |
| Amazon Fire TV Cube (3rd Gen) | 1 | 3 | 3 |
| Google TV Streamer 4K | 1 | 1 | 4 |
| Chromecast with Google TV (4K) | 0 | 0 | 3 |
| Nvidia Shield TV Pro | 0 | 0 | 1 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Streaming Devices buying guide and the reviewers we cite.
