After exclusively using a Snapdragon chip for the Galaxy S23, Samsung is rumored to bring back Exynos chips to at least some Galaxy S24 phones next year. The company could use the Exynos 2400 processor in Galaxy S24 series phones released in Africa, Europe, and parts of Asia, while the Snapdragon 8 Gen 3 could be used in phones sold in China, South Korea, and the US. The specifications of the Exynos 2400 processor have now been leaked.
Exynos 2400 specifications: 10-core CPU, 2x GPU performance compared to Exynos 2200
According to a report from China, the Exynos 2400 is built using an improved version of Samsung Foundry's 4nm fabrication process. Apparently, the chipset uses a 10-core CPU featuring one Cortex-X4 CPU core clocked at 3.1GHz, two Cortex-A720 CPU cores clocked at 2.9GHz, three Cortex-A720 CPU cores clocked at 2.6GHz, and four Cortex-A520 CPU cores clocked at 1.8GHz. In comparison, the Snapdragon 8 Gen 3 is said to feature an octa-core CPU with one Cortex-X4 CPU core, five Cortex-A720 CPU cores, and just two Cortex-A520 CPU cores.
Similar to the Snapdragon 8 Gen 3, the Exynos 2400 is said to be compatible only with 64-bit apps, which means it can't run older 32-bit apps. The chip is rumored to be compatible with UFS 4.0 storage and LPDDR5X RAM with a bandwidth of 8.5Gbps. The built-in ISP (Image Signal Processor) that processes images from the camera sensor can reportedly handle up to 320MP camera sensors and up to 8K 60fps videos.
In the graphics department, the Exynos 2400 is rumored to feature the Xclipse 940 GPU, which uses 2x the GPU cores compared to the Xclipse 920 GPU in the Exynos 2200. It probably means it has six WGPs (workgroup processors) rather than three WGPs in the Exynos 2200. Since each WGP has two CU (Compute Units or cores), the Exynos 2400's Xclipse 940 GPU would have 12 GPU cores. That should theoretically mean twice the graphics performance compared to the Exynos 2200, which should bring the Exynos 2400 to the level of the Snapdragon 8 Gen 2, but we still don't know the clock speeds of these RDNA2 cores, so the performance could be a lot higher.
Exynos 2400 is said to feature two-way satellite communication capability
The Exynos 2400 is also said to offer enhanced AI computing performance compared to its predecessor. Regarding connectivity, the upcoming Exynos chip is said to come equipped with the Exynos 5300 modem unveiled earlier this year. It has up to 10Gbps maximum downlink speeds on a 5G network. Maximum uplink speeds can reach up to 3.87Gbps. It supports NSA and SA 5G networks and is compatible with mmWave and sub-6GHz networks. That's par with the 5G modem in the Snapdragon 8 Gen 2.
The modem is also said to be compatible with two-way satellite connectivity for emergency calling and messaging when there's no cellular network in the area. We expect the Exynos 2400 to support other connectivity features, including BDSm Galileo, GLONASS, GPS, Wi-Fi 6E/Wi-Fi 7, Bluetooth 5.3, NFS, and USB 3.2 Type-C.
