Both models belong to Samsung’s premium QLED series and feature Quantum Dot technology, providing a 10-bit color depth and the ability to display over a billion shades. While their specifications are quite similar, there are a few key differences between them.
Main Differences Between Samsung Q8 and Q80
The most significant upgrade in the 2019 Q80 model is the addition of built-in support for Google Assistant and Amazon Alexa, which is absent in the 2018 Q8. This makes the Q80 more convenient for smart home integration. Another difference is the operating system version. The Q80 runs on Tizen 5.0, which improves voice command functionality and includes minor optimizations, while the Q8 operates on an earlier version. However, in everyday use, the difference is barely noticeable.
Both TVs feature full-array local dimming technology, though they are marketed under different names. The Q80 uses the term Direct Full Array 8X³, while the Q8 is labeled as Full Array Backlight. Despite the name change, the underlying technology remains the same. The same applies to local dimming: Ultimate UHD Dimming in the Q80 and Supreme UHD Dimming in the Q8 offer virtually identical performance.
Regarding color processing, Samsung uses different marketing terms for the same technology. The Q80 features 100% Color Volume with Quantum Dot, while the Q8 is labeled Q Color, but there is no difference in actual color reproduction. HDR technology is also unchanged. The Q80 is marketed with Quantum HDR 12X, while the Q8 is labeled with Q HDR Elite. However, both models deliver the same HDR performance, with identical brightness and contrast levels.
