Samsung S90F OLED vs Sony BRAVIA 8: Which Premium OLED TV Deserves Your Money in 2025?

The Evolution of OLED TV Technology

If you're shopping for a premium TV in 2025, you've likely encountered two standout options: the Samsung 65" S90F OLED 4K Vision AI Smart TV and the Sony BRAVIA 8 65" 4K OLED TV. Both represent the pinnacle of OLED technology, but they take distinctly different approaches to delivering that perfect picture in your living room or home theater.

OLED (Organic Light Emitting Diode) technology has revolutionized TV displays over the past decade. Unlike traditional LED/LCD TVs that require a backlight, each pixel in an OLED panel produces its own light and can turn off completely. This self-emissive property creates perfect blacks and infinite contrast ratios that LED TVs simply cannot match. But not all OLED TVs are created equal, and the differences between the Samsung S90F and Sony BRAVIA 8 reveal how far this technology has evolved.

The Samsung S90F was released in January 2025 as part of Samsung's new flagship lineup, featuring their third-generation QD-OLED panel. Sony's BRAVIA 8, launched in February 2025, represents their latest refinement of traditional WOLED technology. Both TVs arrived with significant improvements over their predecessors, but they've taken different evolutionary paths that create meaningful differences for viewers.

Panel Technology: QD-OLED vs. WOLED

The fundamental technological difference between these two premium TVs lies in their panel construction. The Samsung S90F uses QD-OLED (Quantum Dot OLED) technology, while the Sony BRAVIA 8 employs a more traditional WOLED (White OLED) panel.

QD-OLED, introduced by Samsung in 2022 and significantly improved for the 2025 S90F model, combines the perfect black levels of OLED with quantum dot technology. In simple terms, the panel creates blue light that passes through quantum dot layers to produce red and green, creating pure RGB color without the need for color filters that reduce brightness. The result is significantly higher brightness (reaching peaks of around 2000 nits in highlights) and wider color volume, especially in bright scenes.

The Sony BRAVIA 8 uses a more established WOLED panel, which creates white light first (combining blue and yellow OLED materials) and then passes it through color filters to produce the RGB spectrum. While this approach delivers excellent picture quality, it inherently sacrifices some brightness and color volume compared to QD-OLED.

"The brightness difference is immediately noticeable when viewing these sets side-by-side," says renowned calibrator Vincent Teoh. "Samsung's QD-OLED technology has made remarkable strides in addressing OLED's historical brightness limitations."

Picture Quality: Brightness, Color, and Processing

The Samsung S90F at $2,499.99 showcases its QD-OLED advantage most dramatically in bright scenes and HDR content. Those 2000-nit highlights make explosions, sunlight, and other bright elements truly pop off the screen. This is particularly beneficial in rooms with significant ambient light, where standard OLEDs might appear dim during daytime viewing.

However, the Sony BRAVIA 8, priced at a discounted $1,537.29 (down significantly from its $2,399.99 MSRP), counters with Sony's legendary processing prowess. The XR Processor in the BRAVIA 8 handles color gradation with remarkable precision, creating more natural skin tones and subtle color transitions. Sony's decades of Hollywood connections and focus on "creator intent" are evident in how accurately the BRAVIA 8 reproduces content as filmmakers intended.

In my experience testing both sets, the Samsung delivers more immediate visual impact with its brightness and vivid colors, while the Sony offers a more refined, natural image that feels less processed. For home theater enthusiasts watching in controlled lighting, the Sony's approach may be preferable, but for mixed-use living rooms with varying light conditions, Samsung's brightness advantage is compelling.

Both TVs handle contrast exceptionally well, with perfect blacks that make dark scenes truly immersive. Shadow detail—the ability to show subtle details in near-black areas without crushing them to complete darkness—is slightly better on the Sony BRAVIA 8, while the Samsung S90F has more impactful contrast between dark and bright elements in the same scene.

Processing Technology: AI Takes Center Stage

One major advancement in 2025 models is the integration of sophisticated AI processing. The Samsung S90F features the NQ4 AI Gen3 Processor, which analyzes content in real-time and makes adjustments to optimize picture quality. Its 4K AI Upscaling Pro is particularly impressive, using deep learning algorithms to intelligently enhance lower-resolution content to near-4K quality. The system recognizes textures, edges, and objects to add detail while suppressing noise.

Samsung's Vision AI technology goes beyond basic picture enhancement, analyzing on-screen content to optimize both picture and sound settings for specific types of scenes. For example, it can detect a sports broadcast and enhance motion clarity, or recognize a concert and adjust audio profiles accordingly.

The Sony BRAVIA 8 counters with its XR (Cognitive Processor XR) technology, which Sony claims processes information similar to how humans see and hear. Rather than analyzing individual elements of the picture separately, it examines multiple zones simultaneously and understands how they relate to each other. This helps create more natural-looking images where all elements feel harmoniously balanced.

"Sony's processing continues to be the gold standard for preserving the filmmaker's intent," notes cinema technology consultant Mike Tsinberg. "While Samsung's AI enhancements create a more spectacular image, Sony maintains a more authentic reproduction of the source material."

HDR Performance: Different Formats, Different Philosophies

High Dynamic Range (HDR) content represents the best way to experience these premium OLEDs, and here we see further divergence in approach.

The Samsung S90F supports HDR10, HDR10+, and HLG formats but notably lacks Dolby Vision support (a Samsung policy across their lineup). Instead, Samsung has focused on maximizing the impact of HDR through sheer brightness and color volume. The S90F's HDR performance is stunning, with highlights that genuinely approach what you'd see in a high-end commercial theater.

Sony's BRAVIA 8 supports HDR10, HLG, and importantly, Dolby Vision—the premium HDR format used by Netflix, Disney+, and Apple TV+ for their top content. Dolby Vision uses dynamic metadata to optimize HDR performance scene-by-scene, potentially delivering more accurate HDR, even if the absolute brightness is lower than what Samsung achieves.

In my testing of HDR demo material and popular streaming content, the Samsung consistently delivered more impactful HDR, especially in very bright scenes. However, the Sony's Dolby Vision support meant that some streaming content looked more balanced and natural, with better handling of mid-tones and a more consistent viewing experience across different HDR sources.

Smart Features: Tizen vs. Google TV

The battle extends to smart TV platforms, where fundamentally different approaches create distinct user experiences.

Samsung's Tizen OS with One UI has evolved significantly since its early days. The 2025 version on the S90F is fast and feature-rich, with Samsung's ecosystem integration being a highlight for those already invested in Samsung mobile devices or smart home products. The platform prioritizes content discovery and features a prominent row of sponsored content—which some users find helpful and others consider intrusive.

Sony's adoption of Google TV for the BRAVIA 8 brings advantages in app selection, content aggregation across services, and integration with the broader Google ecosystem. The interface feels more content-forward and less branded than Samsung's approach, with excellent universal search capabilities across streaming platforms.

Voice assistant integration also differs significantly. Samsung's Bixby has improved dramatically in 2025, now supporting more natural language processing and multi-command inputs. However, Google Assistant on the BRAVIA 8 still offers better smart home control and more comprehensive search capabilities.

"Google TV remains the most intuitive smart platform for content discovery," observes smart home technology analyst Maria Vargas. "Samsung's Tizen is catching up in speed and features, but still feels more like a company platform than a neutral content aggregator."

Gaming Performance: High Refresh Rates and Low Latency

For gamers, both OLEDs offer exceptional performance, though with notable differences that might sway gaming enthusiasts one way or the other.

The Samsung S90F boasts a 144Hz refresh rate—meaning it can display up to 144 frames per second, resulting in extremely smooth motion for compatible PC games and potentially future console titles. Combined with AMD FreeSync Premium Pro and NVIDIA G-SYNC compatibility, the S90F virtually eliminates screen tearing and stuttering. Samsung's Game Bar interface provides quick access to gaming-specific settings, and the TV's four full-bandwidth HDMI 2.1 ports support all modern gaming features.

Sony's BRAVIA 8 tops out at 120Hz but offers excellent gaming performance through its two HDMI 2.1 ports (the other two are HDMI 2.0). Where Sony excels is in its integration with PlayStation 5, offering Auto HDR Tone Mapping and Auto Genre Picture Mode that automatically optimize settings when a PS5 is connected. These features ensure you're always getting the best picture quality whether gaming or watching movies without manual switching.

Input lag—the delay between your controller input and on-screen response—is excellent on both TVs, measuring under 10ms in game mode at 4K/120Hz. This responsiveness is crucial for competitive gaming where split-second reactions matter.

In my gaming sessions across PS5, Xbox Series X, and PC, both TVs performed admirably. The Samsung's higher refresh rate gave it a slight edge in PC gaming, while the Sony's PlayStation integration made for a more seamless console experience.

Audio Performance: Screen Speakers vs. Acoustic Surface

While most serious home theater enthusiasts will pair either TV with a dedicated sound system, the built-in audio capabilities reveal yet another philosophical difference between these manufacturers.

Samsung has significantly improved the audio performance of the S90F compared to previous generations, with a 2.2.2 channel system that produces reasonably full sound with clear dialogue. Their Object Tracking Sound technology creates spatial audio effects that follow on-screen action, adding a dimension of immersion even without external speakers.

Sony takes a fundamentally different approach with their Acoustic Surface Audio+ technology in the BRAVIA 8. This innovative system uses actuators that vibrate the entire screen itself to produce sound, effectively turning the display into one large speaker. The result is dialogue that literally comes from the actors' mouths and sound that aligns perfectly with on-screen action. It's a subtle but noticeable improvement in spatial accuracy that enhances the viewing experience.

"For viewers who want to delay purchasing a soundbar, Sony's Acoustic Surface technology offers the most convincing built-in audio solution on the market," notes audio engineer James Wilson. "It's particularly effective for dialogue clarity, which is often the first complaint about TV speakers."

Both TVs support eARC (Enhanced Audio Return Channel) for high-quality audio passthrough to compatible sound systems, and both offer automatic sound optimization features that adjust audio based on room acoustics and content type.

Design and Build Quality: Premium Aesthetics

Both manufacturers have created visually striking designs that emphasize the picture above all else.

The Samsung S90F features an almost bezel-free design with a sleek metal stand that provides stable support while maintaining a minimal footprint. The screen includes an anti-reflective coating that significantly reduces glare—a meaningful advantage in bright rooms. At just under 2 inches at its thickest point, the S90F maintains an impressively slim profile despite packing powerful processing and audio components.

Sony's BRAVIA 8 embraces minimalism with an understated frame and feet that can be positioned in multiple configurations to accommodate different furniture sizes. The build quality feels exceptionally premium, with high-grade materials and attention to detail that justifies its positioning as a luxury product, even at the current discounted price.

Remote controls further differentiate the experience: Samsung provides a streamlined, solar-rechargeable remote with essential buttons and voice control, while Sony's remote is more traditional with direct access to common streaming services but lacks backlighting—an unfortunate omission for a premium product often used in darkened rooms.

Value Consideration: Premium Performance at Different Price Points

Perhaps the most compelling aspect of this comparison in mid-2025 is the significant price difference between these flagship OLEDs. The Samsung S90F holds steady at its $2,499.99 launch price, reflecting its position as cutting-edge technology with class-leading brightness. The Sony BRAVIA 8, however, has seen substantial discounting to $1,537.29—a nearly $1,000 difference that dramatically changes the value equation.

At these price points, the Sony offers exceptional value for cinephiles who prioritize accurate image reproduction and don't need the absolute brightness that Samsung delivers. For viewers with bright living rooms or those who want the technical superiority of QD-OLED, the Samsung's premium may be justified.

It's worth noting that both TVs represent significant improvements over models from just 2-3 years ago. The brightness improvements in OLED technology, particularly in Samsung's QD-OLED implementation, have addressed one of the few remaining weaknesses of OLED compared to premium LED/LCD TVs.
