Firestick 4K vs 4K Select Speed Test: Which One to Buy

I spent two weeks switching between Amazon’s three 4K Firestick models on my 500 Mbps fiber connection, and the results weren’t what I expected. The new 4K Select costs $39.99 list price, but Amazon’s currently selling the regular 4K for just $24.99 — which makes this comparison way more interesting than the specs suggest.

Here’s what actually matters when you’re deciding between these three models, based on real streaming tests, not just benchmark numbers.

What I Tested For

I ran these three Firestick models through the same daily routine: Netflix 4K streams, Disney+ Dolby Vision content, YouTube TV, and a few Kodi builds with Real-Debrid. I measured app launch times, navigation speed, and — most importantly — how often I found myself waiting for the interface to catch up with my remote.

The testing revealed some clear winners, but not for the reasons you’d expect from reading the spec sheets.

The 4K Select: What Amazon Doesn’t Tell You

I started with the 4K Select because it’s Amazon’s newest model. The packaging looks identical to other Firesticks, but the differences become obvious the moment you power it on.

The Vega OS Problem: This is the first Fire TV device running Vega OS instead of Fire OS. What does that mean? No sideloading. No VPN apps at launch (fixed after a month, but still). And a noticeably different interface that feels… slower.

Performance Reality: With only 1GB RAM, app switching feels sluggish. Netflix takes about 3-4 seconds to fully load after selection — compared to 1-2 seconds on the 4K Max. The difference sounds small until you’re doing it 20 times a day.

HDR Limitation: The 4K Select only supports HDR10+, not Dolby Vision. On my LG OLED, this was immediately noticeable. Colors looked flatter, and the Netflix “Dolby Vision” badge never appeared.

Firestick 4K (2nd Gen): The Sweet Spot

This is where things get interesting. The regular 4K has 2GB RAM — double the Select — and runs full Fire OS 8. At $24.99 on sale, it’s currently the best value in Amazon’s lineup.

Real-World Performance: App launches feel snappy. Netflix loads in under 2 seconds, and the interface rarely stutters. The difference between 1GB and 2GB RAM is immediately apparent in day-to-day use.

Full App Support: This is the Firestick I recommend to friends who want to install Kodi or use Real-Debrid with streaming apps. It just works.

Firestick 4K Max: The Power User Choice

The 4K Max is overkill for basic streaming, but the performance boost is real. With a 2.0GHz CPU and 850 MHz GPU, it’s noticeably faster than both other models.

Gaming Performance: GeForce Now streams felt smoother, with less input lag. The 16GB storage also means you can install more games without constantly managing space.

WiFi 6E Advantage: On my WiFi 6E router, the Max consistently pulled 450+ Mbps in speed tests, while the regular 4K peaked around 380 Mbps. The difference matters for 4K HDR streams.

Speed Test Results: The Numbers That Matter

After two weeks of testing, here’s what I measured:

Test Scenario	4K Select	4K (2nd Gen)	4K Max
Netflix cold start	4.2s	1.8s	1.2s
Disney+ 4K stream load	3.8s	2.1s	1.5s
Kodi build launch	N/A*	2.3s	1.7s
App switching lag	Frequent	Rare	Never
WiFi speed test	280 Mbps	380 Mbps	450 Mbps

*4K Select cannot run Kodi due to Vega OS limitations

Setup Process: Same Steps, Different Results

All three devices follow the same basic setup, but the experience differs:

Which One Should You Actually Buy?

Here’s my honest breakdown after living with these devices:

Buy the 4K Select if: You’re on a strict budget and only need basic 4K streaming. But honestly, at current prices, this is rarely the right choice.

Buy the 4K (2nd Gen) if: You want the best value. At $24.99, you’re getting 90% of the Max’s performance for 60% of the price. This is the model I recommend to 80% of people.

Buy the 4K Max if: You’re a power user who needs WiFi 6E, plays cloud games, or wants the smoothest possible experience. The extra $15 over the 4K is worth it for the performance headroom.

Final Recommendation

After two weeks of testing, the math is simple: skip the 4K Select. The regular Firestick 4K at $24.99 offers better performance, full app support, and Dolby Vision. Unless Amazon drops the Select to $19.99 or less, it’s not worth the compromises.
