Exynos 2600: Samsung’s First 2nm GAA Chipset for Galaxy S26 Series

Samsung’s journey with the 3nm Gate-All-Around (GAA) process has been tumultuous, leading many to believe that the tech giant would prefer to forget that chapter altogether. However, having learned from previous challenges, the company is now poised for redemption with its 2nm GAA technology. The Exynos 2600 has been introduced as the first System on Chip (SoC) mass-produced using this innovative process, marking a pivotal moment in Samsung’s semiconductor history.

Exploring Samsung’s 2nm GAA Process: A Competitor to TSMC’s 2nm Technology

In order to rival TSMC effectively, Samsung must not only enhance its yield rates but also bolster its technological edge. Recent reports indicated that the yield rates for Samsung’s 2nm GAA were around 30%, significantly better than the difficulties faced with the 3nm GAA process. As the Exynos 2600 is set for mass production by the end of September, these yield rates are encouraging, suggesting Samsung is prepared for full-scale manufacturing without heavy financial repercussions.

The initial 2nm GAA process, dubbed SF2, is expected to offer impressive enhancements: up to 12% better performance, 25% improved power efficiency, and a 5% reduction in chip area compared to 3nm GAA technologies. This new GAA architecture enhances chipset design flexibility and scalability, potentially allowing Samsung to efficiently adapt the Exynos 2600 for notebook applications. This strategy mirrors Apple’s successful approach of utilizing its A-series architecture for M-series products. Additionally, the incorporation of Backside Power Delivery Network (BSPDN) promises further enhancements in power management.

Despite potential improvements, Samsung’s reputation has been marred by past failures, particularly as TSMC has capitalized on opportunities that Samsung overlooked. The Exynos 2600 will serve as the company’s vital test to validate its manufacturing prowess. A successful launch could entice customers back to Samsung as they begin to place orders for this promising technology.

In a positive development, Tesla has signed a substantial $16.5 billion agreement with Samsung to produce chips using the new lithography, indicating that the company is indeed making strides towards recovery.

Specifications Overview: CPU, GPU, NPU, and More

Samsung has hinted that the Exynos 2600’s Neural Processing Unit (NPU) will significantly outperform its predecessor, the Exynos 2500, although specific details have remained scarce. Benchmark leaks, however, have unveiled crucial information, revealing a 10-core configuration for this new chipset. It is anticipated to feature a ‘1 + 3 + 6′ core arrangement, although earlier single-core and multi-core results did not fully capture the Exynos 2600’s performance capabilities, indicating that the chip was still undergoing testing with lower clock frequencies.

Recent benchmark updates indicate a remarkable performance for the Exynos 2600, matching a downclocked Snapdragon 8 Elite Gen 5 in multi-threaded benchmarks. Specifically, the single core operates at 3.80GHz, with three high-performance cores at 3.26GHz and six efficiency cores at 2.76GHz. While increasing the core count enhances multi-core performance, it can also lead to efficiency issues and heightened power consumption. Fortunately, Samsung has reportedly developed strategies to mitigate these concerns.

Addressing Overheating: Samsung’s Innovative Heat Pass Block Technology

Samsung recognizes the need to manage heat generation in its chipsets to ensure robust performance. Advanced manufacturing techniques are being implemented in the Exynos 2600 to tackle this issue. Additionally, the integration of ‘Fan-out Wafer Level Packaging’ (FOWLP) that debuted with the Exynos 2400 is expected to continue for the Exynos 2600. This packaging method enhances cooling efficiency and reduces heat buildup.

Another significant advancement is the introduction of the ‘Heat Pass Block’ (HPB) technology in the Exynos 2600. This technology functions similarly to cooling solutions found in laptops, acting as a heatsink to mitigate temperature rises caused by adjacent DRAM chips. When combined with FOWLP, the HPB is anticipated to elevate sustained performance levels by improving thermal resilience. Samsung is also contemplating an aluminum chassis for the upcoming Galaxy S26 series, akin to Apple’s iPhone 17 Pro, which could further enhance heat dissipation.

Which Galaxy S26 Model Will Feature the Exynos 2600?

Traditionally, Samsung has equipped its Galaxy S Ultra models with Snapdragon chips, leaving Exynos variants for the more affordable Galaxy S models. However, as the Exynos 2600 approaches mass production, there are suggestions that the high-end Galaxy S26 Ultra could also incorporate this new silicon. Reports indicate a potential dual-sourcing strategy, providing both Snapdragon 8 Elite Gen 5 and Exynos 2600 options depending on the region.

This change is vital, especially considering the frustrations voiced by customers who purchased Exynos models at the same price point as their Snapdragon counterparts but felt they received a product of lesser quality. As the launch date approaches in 2026, it is crucial for Samsung to ensure its SoC competes with the Snapdragon 8 Elite Gen 5 in terms of performance.

Expected Launch Timeline

Samsung has consistently unveiled its new Exynos chipsets prior to the release of its flagship Galaxy S smartphones. If the company adheres to this schedule, we might anticipate the Exynos 2600’s launch in October, promising a refreshing turnaround for Samsung in the consumer tech landscape.
