Early work on the Exynos 2800 is reportedly underway, and this is the processor expected to power the Galaxy S28 lineup in 2028. It’s still early days, but the direction Samsung is taking is starting to become clearer.

According to a report from Korea, the company wants to wrap up the design of the Exynos 2800, codenamed Vanguard, sometime in 2026. After that, it will be handed over to Samsung’s foundry division for production. The chip is expected to be built on the company’s third-generation 2nm process, referred to as SF2P+.

Samsung had earlier plans to move more aggressively toward a 1.4nm process around 2027, but that no longer seems to be the priority. Instead, the focus now is on improving yields and making sure the process is stable enough before pushing further. The 1.4nm node is now expected to arrive later, possibly closer to 2029.

This change doesn’t come as a huge surprise. Shrinking chip sizes every year is getting harder, and the gains aren’t always as straightforward as they used to be. Samsung now seems to be leaning more on design and manufacturing working closely together, rather than just chasing smaller numbers on paper.

The upcoming Exynos 2700, which is also expected to use a 2nm process, is said to be progressing smoothly. That probably gives Samsung some confidence that this approach is working, at least for now.

For Samsung, this is about more than just hitting a new node. Previous Exynos chips haven’t always matched Snapdragon in areas like efficiency and heat management. Focusing on stability and optimization could help narrow that gap.

There’s still no word on CPU or GPU details for the Exynos 2800, which isn’t surprising this far out. But if things go according to plan, the Galaxy S28 could end up benefiting from a more refined and balanced chip than what we’ve seen in the past.

Samsung could be preparing a major shift in its chip strategy with a future Exynos processor. According to recent leaks, the company is exploring fully custom CPU and GPU designs for the Exynos 2800, marking a possible return to in-house core development after several years of relying on external partners.

The information comes from Weibo tipster Smart Chip Guide. If accurate, the Exynos 2800 would move away from standard ARM CPU cores and also end Samsung’s use of AMD’s RDNA-based GPUs, which have powered flagship Exynos chips since 2022.

This wouldn’t be Samsung’s first attempt at custom CPUs. Between 2016 and 2020, the company developed its own “Mongoose” cores, designed by its Austin-based team. While those chips showed strong peak performance, they struggled with efficiency and heat management, often falling behind Qualcomm’s Snapdragon chips in real-world use. Samsung eventually shut down the project and returned to off-the-shelf ARM designs.

The new effort suggests Samsung believes the timing is better this time. Advances in manufacturing, including its upcoming 2nm Gate-All-Around (GAA) process, could help address earlier efficiency issues. Developing a custom GPU could also give Samsung more control over AI processing and system-level optimizations across Galaxy devices.

The Exynos 2800 is rumored to debut in the Galaxy S28 series in 2028, leaving Samsung several years to refine the architecture. Before that, the Exynos 2600—expected in the Galaxy S26 lineup—may be the final Exynos chip to use AMD’s RDNA graphics, even though Samsung reportedly handles most of the GPU implementation itself.

If this plan moves forward, it would signal Samsung’s intent to compete more directly with Apple’s tightly integrated silicon strategy. Whether it succeeds, however, remains an open question—especially given the mixed legacy of its earlier custom designs.
