When we talk about 4K smart TVs from Samsung, two popular Crystal UHD models often compared are the Samsung U8000F and the Samsung U7900F. Both belong to Samsung’s 2025 lineup, combining 4K clarity, vibrant color processing, and the smooth performance of the Crystal Processor 4K with 3D Color Mapping.
They share the same MetalStream design, slim build, and Samsung’s Tizen OS, offering effortless access to streaming platforms, voice control, and endless entertainment options. But if they look and perform this similarly, is there still a reason to choose the U8000F over the U7900F?
The Samsung U8000F is available in eight screen sizes: 43″ (UN43U8000FFXZA), 50″ (UN50U8000FFXZA), 55″ (UN55U8000FFXZA), 58″ (UN58U8000FFXZA), 65″ (UN65U8000FFXZA), 70″ (UN70U8000FFXZA), 75″ (UN75U8000FFXZA), and 85″ (UN85U8000FFXZA). Meanwhile, the Samsung U7900F also comes in the same sizes: 43″ (UN43U7900FFXZA), 50″ (UN50U7900FFXZA), 55″ (UN55U7900FFXZA), 58″ (UN58U7900FFXZA), 65″ (UN65U7900FFXZA), 70″ (UN70U7900FFXZA), 75″ (UN75U7900FFXZA), and 85″ (UN85U7900FFXZA).
In other words, they are nearly identical twins — except for a few small but practical differences. Let’s take a closer look.
Samsung U8000F Short Review
The Samsung U8000F delivers stunning 4K clarity with enhanced color accuracy thanks to 3D Color Mapping powered by the Crystal Processor 4K. It also supports HDR10+, ensuring balanced brightness and contrast for both bright and dark scenes.
With its MetalStream design, the U8000F blends premium aesthetics with durability. The Direct Lit LED panel provides even backlighting, while the Motion Xcelerator (60 Hz) keeps motion smooth and natural during sports or gaming.
Running on Tizen OS, it provides seamless access to major streaming apps and Samsung TV Plus. It also includes Auto Low Latency Mode (ALLM) for improved gaming response. Connectivity is solid with 3 HDMI ports (one with eARC), 1 USB, Ethernet LAN, Optical Audio Out, Bluetooth 5.3, and Wi-Fi 5.

Samsung U7900F Short Review
The Samsung U7900F mirrors the U8000F in almost every way — from the elegant MetalStream design to the same Crystal Processor 4K with 3D Color Mapping and HDR10+ support. It delivers clear, vibrant visuals and smooth motion through the same Motion Xcelerator (60 Hz) engine.
Picture performance is excellent for its class, with crisp detail and realistic color reproduction. The Tizen OS platform ensures intuitive access to all popular apps, while ALLM provides low-lag responsiveness for console gamers.
The only practical difference lies in its ports: the U7900F includes 2 HDMI ports (one with eARC) instead of 3. It retains 1 USB, Bluetooth 5.3, and Wi-Fi 5 connectivity.

The Differences Between Samsung U8000F and U7900F
Given all the shared technology, the two TVs are nearly identical in picture quality, smart experience, and motion handling. Still, there are a few small distinctions worth noting:
- HDMI Connectivity
The U8000F includes 3 HDMI ports, while the U7900F offers 2. If you use multiple devices — a gaming console, soundbar, and streaming box — that extra port can make a difference. - Pricing
The U7900F is usually priced a bit lower across all sizes, making it the better value if you don’t need that third HDMI input.
Why Should You Choose Samsung U8000F?
If you need the extra HDMI port or just prefer the most complete feature set in the Crystal UHD line, the Samsung U8000F is a safe pick. It offers the same picture quality and motion smoothness as the U7900F but adds slightly better connectivity and more flexibility for multi-device setups.
