Samsung’s cutting-edge 1.4nm node takes a big step forward as the company begins its early testing on the upcoming Exynos chipset. The upcoming Exynos chip in question will reportedly have higher peak clock speeds and a massive 96MB of System Level Cache (SLC), along with many notable upgrades.

Since Samsung’s more focused on improving the yield stability of its 2nm process, we’ll see a couple more iterations of the 2nm GAA process before the 1.4nm process enters mass production. That also means the 1.4nm Exynos chip under testing is unlikely to be the unreleased Exynos 2700. Regardless, the early details of this 1.4nm Exynos chip, shared by @SPYGO19726, look promising.

The chip will have a 10-core CPU cluster divided into a ‘2+4+4’ configuration. The two prime cores achieve a maximum speed of 4.50GHz, while the current Exynos 2600 peaks at 3.8GHz. That’s a solid 19% jump in the peak speed. Further, the four performance cores operate at 3.80GHz, and the four efficiency cores run at 2.00GHz.

Perhaps the most exciting development of this Exynos chip is the integration of 96MB of SLC cache. The tipster also reports an ultra-wide bus width to minimize latency between the CPU cores and the GPU. A large SLC can store much more frequently used data to achieve a lower memory latency and a boost in bandwidth. This effectively reduces the need for components such as CPU, GPU, NPU, and ISP to remain active all the time to send information to the larger cache.

Unfortunately, it’s more expensive to produce chipsets with a large SLC cache because it occupies a significant portion of the silicon die. And with larger dies, production costs also go up. It’s important to note that 10MB is the highest SLC cache in smartphone chips, found in the Dimensity 9500. Bumping it to 96MB would result in a die size incompatible with smartphone form factors. However, it can be used in many other device categories.

With Samsung targeting 2029 for the mass production of its 1.4nm node, there’s still plenty of time for development and optimizations. Therefore, it’s best to treat these early details with a grain of salt. Consequently, while these early specifications are exciting, it’s best to treat them with a grain of salt.

When it comes to mobile and electronic processors, the manufacturing technique plays a huge role. The smaller the process node, the better the SoC performance, or at least that’s the notion. By now, you might have heard of or used chipsets based on 4nm technology, such as the Snapdragon 8 Gen 2 and Dimensity 8200, to name a few. However, we have yet to see any chip based on the 3nm node. This may change with the Apple iPhone 15. In the meantime, there’s news that Samsung is planning to commence production of 2nm chips in 2025, followed by 1.4nm chips in 2027.

Samsung aiming for more advanced processors

Samsung Foundry is the world’s second-largest contract chip producer after TSMC, and the Korean company is determined not to be left behind. In early 2022, TSMC announced its plans to introduce 2nm technology to the world by 2025. Now, Samsung has confirmed that it is targeting a similar timeline. During its Forum held in San Jose, California on Tuesday, the South Korean tech giant stated that it wants to start mass production of 2nm mobile chips in 2025.

If you are not familiar, nm stands for nanometer, and it refers to the channel length of the transistors that make up a chip. A smaller channel length allows for more transistors to be densely packed onto a single chip, leading to improved performance.

Once Samsung is done testing the 2nm chips in 2025, it will offer the advanced process for high-performance computing in 2026. Furthermore, by 2027, the Korean company aims to offer a process specifically designed for automotive chips.

The company compares its newly developed 2nm process with the 3nm process that was launched last year. The smaller processor node is claimed to provide a 12% increase in performance and a 25% increase in power efficiency compared to Samsung’s 3nm process. The 2nm process also allows Samsung to design chips that are 5% smaller than those produced using its 3nm process. Furthermore, the company has announced its plans to initiate mass production of chips utilizing its 1.4nm process in 2027.
