The 2025 CES event was expected to showcase a plethora of Thunderbolt 5 (TB5) enabled devices, marking a significant leap in data transfer technology. However, the reality was starkly different, with a noticeable absence of TB5-compatible laptops and devices. This unexpected scenario has raised questions about the factors hindering the widespread adoption of Thunderbolt 5, despite its promising technological advancements.

High Expectations and Disappointing Reality

Anticipation for Thunderbolt 5 at CES 2025

The tech community had high hopes for Thunderbolt 5, anticipating its presence in numerous devices at CES 2025. The technology, announced in late 2023, promised significant improvements over its predecessor, Thunderbolt 4 (TB4). With data transfer rates of up to 80 Gbps and support for multiple high-resolution displays, TB5 was expected to revolutionize connectivity standards. The anticipation was rooted in TB5’s ability to handle complex data tasks and support cutting-edge applications seamlessly, which was supposed to make it a favorite among tech enthusiasts and professionals alike.

However, the reality at CES 2025 turned out to be quite underwhelming. The exhibition halls, which were expected to be lined with TB5-enabled laptops and accessories, instead showcased an overwhelming number of TB4 devices. This stark contrast between expectations and reality has left many industry watchers scratching their heads. Was the hype around Thunderbolt 5 premature, or were there deeper issues preventing its rapid adoption?

The Dominance of Thunderbolt 4

Contrary to expectations, Thunderbolt 4 continued to dominate the CES 2025 landscape. Devices featuring TB4 ports were ubiquitous, indicating that manufacturers still preferred this older standard. The reasons behind this preference are multifaceted, involving both technical and economic considerations. TB4’s integration into Intel’s Core series processors has made it a go-to connectivity option for many device manufacturers, streamlining production processes and reducing costs.

Moreover, Thunderbolt 4’s current specifications seem to meet the needs of most users. With data transmission speeds of up to 40 Gbps and support for two 4K displays at 60Hz, TB4 offers reliable performance for a broad range of applications. This existing capability, along with the significant infrastructure already built around TB4, has created little urgency for manufacturers to transition to the newer TB5 standard, despite its higher performance potential.

Technical Barriers to Adoption

Lack of Integrated Chipsets

One of the primary technical barriers to TB5 adoption is the lack of integrated chipsets. Intel, a key player in the development of Thunderbolt technology, has not yet released chipsets with built-in TB5 support. This absence forces manufacturers to rely on discrete TB5 chips, which add complexity and cost to device production. Without integrated solutions from major chipset manufacturers like Intel, the deployment of TB5 remains a challenging venture for most OEMs.

The reliance on discrete chips can also complicate device design and integration. Discrete chips require additional board space and power management considerations, factors that can disrupt the streamlined design and engineering processes that manufacturers have already established. This added complexity can deter companies from quickly adopting TB5, especially when the benefits do not yet outweigh the logistical and financial burdens.

Comparison of Thunderbolt Specifications

To understand the reluctance to adopt TB5, it is essential to compare it with TB4. Thunderbolt 4 supports data transmission up to 40 Gbps and can handle two 4K displays at 60Hz. In contrast, Thunderbolt 5 doubles the data rate to 80 Gbps and supports three 4K displays at 144Hz or two 8K displays at 60Hz. Despite these impressive specifications, the practical benefits of TB5 are not yet compelling enough for widespread adoption.

For many users, TB4 already provides adequate performance capabilities. Common applications, such as video editing, gaming, and professional graphic design, can be efficiently managed with TB4’s bandwidth and display support. The leap from 40 Gbps to 80 Gbps of data transmission speed, while significant, does not yet offer a noticeable enhancement in present daily tasks for most consumers. Thus, without a pressing need for its advanced features, TB5 remains an attractive but not compelling upgrade.

Economic and Market Considerations

The Stalled Transition to 8K Content

A significant factor in the slow adoption of TB5 is the stalled transition to 8K content. The demand for 8K displays remains minimal, as 8K content is not yet widely available. Without a compelling need for 8K displays, the advantages of TB5 are less relevant to most consumers and businesses. The technology to produce and distribute 8K content at scale is still developing, which means that content creators and consumers are not yet investing heavily in 8K infrastructure.

Furthermore, 8K content creation requires significantly higher resources in terms of storage, processing power, and rendering time. These requirements translate to higher costs, which deters content producers from shifting focus entirely to 8K. Consequently, the limited availability of 8K content perpetuates a low demand for 8K displays, thereby reducing the urgency for manufacturers to adopt technologies like TB5 that cater primarily to these high-end use cases.

Cost-Benefit Analysis for Manufacturers

From an economic perspective, manufacturers struggle to justify the additional costs associated with integrating TB5. The lack of integrated chipsets means higher production costs, which are not offset by a clear demand for TB5’s advanced features. As a result, many manufacturers continue to favor TB4, which meets the current market needs at a lower cost. The economics of scale play a crucial role here; producing devices with TB4 is more cost-effective due to the maturity of the technology and the well-established supply chains.

Manufacturers are also cautious about passing on these added costs to consumers. The consumer electronics market is highly price-sensitive, and any significant price increase due to the integration of TB5 could negatively impact sales. With TB4 sufficiently meeting consumer demands, there is little incentive for manufacturers to bear the extra cost burden themselves. Hence, the economic calculus continues to favor the tried-and-tested TB4 over the newer TB5.

Early Thunderbolt 5 Devices and Their Limitations

Limited Showcase at CES 2025

Despite the overall scarcity of TB5 devices, a few products were showcased at CES 2025. These included LG’s 6K display, Asus’ eGPU, and LaCie’s TB5 SSDs. However, these products do not fully leverage TB5’s capabilities and face the challenge of needing compatible laptops to realize their potential. The limited presence of these devices at CES underlined the barriers to TB5 adoption and highlighted the disconnect between TB5’s potential and its practical implementation in consumer-grade products.

The early TB5 devices that did make it to CES were showcased more as proof-of-concept than as mainstream products ready for mass adoption. This demonstrates that while the technology is ready, the ecosystem required to support it is not fully developed. Manufacturers may be wary of promoting devices that only appeal to a niche audience due to the lack of widespread TB5-enabled laptops, further slowing the adoption process.

Niche Applications and Market Segments

The early adopters of TB5 are primarily in niche markets that require high data throughput, such as certain professional applications and high-end gaming setups. For most mainstream users, the benefits of TB5 are not yet compelling enough to drive adoption, especially given the higher costs involved. For instance, industries that deal with large data sets, such as video editing and 3D rendering, can benefit immensely from TB5’s increased bandwidth, but these segments do not represent the bulk of the consumer electronics market.

Moreover, high-end gaming setups that might take advantage of TB5’s capacity for multiple 4K displays are not universal among gamers. Many gamers are satisfied with 4K resolution and are more interested in higher refresh rates, which TB4 can handle sufficiently. Until there is a broader demand for the kind of high-bandwidth applications that TB5 excels at, its adoption will likely remain confined to these specialized segments. The average consumer, focused more on cost-efficiency than on cutting-edge features, is yet to find a compelling reason to opt for TB5-enabled devices.

Industry Trends and Future Outlook

Mainstream Adoption of Thunderbolt 4

The consensus within the industry is that Thunderbolt 4 has become the mainstream port. Integrated into Intel’s Core series processors, TB4 offers sufficient performance for most current applications. This widespread integration ensures that TB4 will remain dominant for the foreseeable future. With TB4 meeting the majority of user needs, from high-speed data transfer to supporting high-resolution displays, the industry is less inclined to push for a shift to TB5 until the market demands it.

Additionally, the infrastructure and accessories that support TB4 are well-established. This includes docks, cables, monitors, and storage solutions, all of which are widely available and relatively affordable. Consumers have already invested in TB4 peripherals, and the compatibility between TB4 and TB5 is not compelling enough to drive a massive upgrade cycle. As such, TB4’s well-rooted presence in the market continues to overshadow the newer TB5.

Incremental Uptake of Thunderbolt 5

While there is recognition of TB5’s superior capabilities, its adoption is expected to be gradual. Industry representatives, including Abdul Ismail, suggest that TB5 will see incremental uptake as related technologies and market demands evolve. The broader trend within the industry is a focus on enhancing refresh rates rather than dramatically increasing resolution beyond 4K. Higher refresh rates provide a noticeable improvement in user experience, especially in gaming and professional settings, without necessitating a complete overhaul of existing hardware.

TB5’s potential for handling higher refresh rates is undoubtedly an advantage, but it is not enough to compel immediate widespread adoption. Instead, as GPU capabilities advance and demand for higher bandwidth increases, TB5 will see a gradual rise in relevance. For now, the industry is focused on optimizing current technologies and ensuring a smooth transition when the time comes for TB5 to take the stage more prominently.
