Both bars support Dolby Atmos and DTS:X, but Samsung adds Dolby TrueHD and Dolby Digital Plus decoding.
If you own a TV from the same brand, both systems offer integration benefits.
TCL's T-Chord syncs the soundbar with compatible TCL TV speakers, while Samsung's Q-Symphony does the same with recent Samsung TVs.
Premium Samsung sets can even send Dolby Atmos audio to the Q990F wirelessly.
Connectivity and Gaming Features
For gamers, the TCL Q95K includes three HDMI 2.1 ports with 48Gbps bandwidth, supporting 4K video at up to 144Hz, Variable Refresh Rate, and Auto Low Latency Mode.
Samsung's HW-Q990F offers two HDMI 2.1 inputs plus an HDMI eARC output, 4K passthrough at 120Hz, and its own VRR support.
For wireless streaming, TCL includes Wi-Fi 6, Bluetooth, Apple AirPlay 2, and Spotify Connect.

Samsung offers Wi-Fi, Bluetooth 5.0, AirPlay 2, and a longer list of services including Tidal Connect, Amazon Music, and Deezer, plus built-in Amazon Alexa voice control.
Price and Availability
The two systems differ significantly in price. The TCL Q95K costs 6,999 yuan in China, roughly $1,034.
TCL also sells step-down models: the Q85K at around $886 and the Q75K at around $694.
However, the Q95K is only available in China, with no timeline for a US, UK, or other Western release.
The Samsung HW-Q990F is already sold worldwide, priced at £1,699 / $1,999 / AU$1,999 at launch.
That is close to double the TCL's Chinese sticker price, though Samsung's Q-series soundbars tend to drop in price over time.
Which One Should You Choose?
Right now, this comparison comes with a caveat. If you live outside China, you cannot buy the TCL Q95K yet unless you import it.
That leaves the Samsung HW-Q990F as the only one you can order today, and reviewers have consistently rated it as one of the best Dolby Atmos soundbars on the market.
If TCL brings the Q95K to Western markets, the pitch becomes more interesting.
It offers more physical drivers, higher peak wattage, and a Bang & Olufsen tuning partnership, all at a price well below Samsung's flagship.
However, Samsung still has the edge in software maturity, format support, streaming service variety, and a long track record of leading global soundbar sales.
For now, buyers outside China have one clear option in this matchup.

Buyers inside China get a genuinely tempting alternative, and the rest of the world will have to wait and see if TCL brings the Q95K home.
