Fire TV Stick 4K (2023) Review – Wi-Fi 6 Speed, AI-Powered Search & Dolby Vision for Under $50

Table of Contents


1. Quick Take

Amazon’s newest Fire TV Stick 4K (2nd Gen, 2023) squeezes Wi-Fi 6, an Alexa remote with app shortcuts and a slick AI search bar into the classic thumb-drive form factor. It now claims 30 % more horsepower and unlocks Dolby Vision / Atmos without bumping the $49.99 list price—and it’s often 40 % off during Prime events.

2. Key Specs

Spec 2023 Fire TV Stick 4K
CPU 1.7 GHz quad-core MT8696
RAM / Storage 1 GB / 8 GB
Max Video 4K UHD @ 60 fps
HDR Dolby Vision, HDR10, HDR10+, HLG
Audio Dolby Digital Plus, Dolby Atmos passthrough
Wireless Wi-Fi 6 dual-band, BT 5.2

MSRP $49.99 (often <$30 on sale)

3. What’s New vs. the 2018 Original

30 % faster SOC—app launch times shrink by ~4 s.
Wi-Fi 6 radio reduces buffering on congested networks.
AI-powered Fire TV Search lets you ask for “comedies with car chases” instead of hunting by app.


4. Setup & Design

Plug the stick into an HDMI port, connect the USB power puck, and you’re streaming in under five minutes. The matte black dongle (99 × 30 × 14 mm) hides behind most TVs, and the latest Alexa remote finally adds dedicated power/volume plus four hot-keys for top apps.


5. Streaming Performance & Picture Quality

In testing, 4K Dolby Vision streams from Prime Video and Disney+ played flawlessly, with HDR highlights punching above the Roku Streaming Stick 4K in side-by-side viewing. Dual-band Wi-Fi 6 kept buffer wheels at bay even while a PS5 hogged the 5 GHz band.


6. Interface & Voice Control

Fire OS remains Amazon-centric—menus relentlessly spotlight Prime Video and Freevee. If you can tolerate the promos, Alexa handles universal search, smart-home commands and even picture-in-picture Ring feeds smoothly. The new AI query engine narrows results by quote, genre or actor with uncanny accuracy.


7. Cloud Gaming Bonus

Pair an Xbox or Luna controller and stream Starfield or Forza through Xbox Game Pass Ultimate—no console required. Latency is playable at 60 fps when your router sits within one room (about ≤25 ms round-trip on our test Eero 6 network).


8. How It Stacks Up

Fire TV Stick 4K Max ($59.99) – Faster CPU, 16 GB storage, Wi-Fi 6E, ambient art mode.
Roku Streaming Stick 4K ($49.99) – Cleaner interface, but no Dolby Vision + Atmos combo.
Chromecast w/ Google TV 4K ($49.99) – Superior content aggregation; slower menu scrolls.

At sale pricing, the Fire TV Stick 4K is the only sub-$35 dongle with Wi-Fi 6 and Dolby Vision.


9. Pricing & Deals

MSRP posts at $49.99, but Amazon’s own sales routinely drop it to ~$29—the current post-Prime-Day promo is 40 % off.


10. Pros & Cons

Pros

• Wi-Fi 6 and Dolby Vision for little money
• AI voice search genuinely useful
• Works as Alexa smart-home hub & Ring viewer
• Frequent sub-$30 deals

Cons

• Home screen overloaded with Amazon promos
• Only 1 GB RAM limits heavy multitasking
• 8 GB storage fills fast with sideloaded apps


11. Verdict

If your 4K TV’s built-in apps stutter—or you’re still on a first-gen Fire Stick—this $50 (often $30) upgrade is a no-brainer. Picture quality rivals pricier streamers, and Wi-Fi 6 future-proofs your network. Interface ads remain the tax you pay for Amazon’s bargain hardware, but for value-minded cord-cutters, the Fire TV Stick 4K is the new entry-level champ.
