CPU and GPU of Galaxy S25’s rumored MediaTek SoC revealed

Samsung could adopt MediaTek chips in its next-generation Galaxy S phones. The company is rumored to utilize the new MediaTek Dimensity 9400 SoC in the Galaxy S25 series, which will feature 3nm flagship Cortex-X925 CPU and Immortalis G925 GPU.

Galaxy S25 series’ rumored MediaTek Dimensity 9400 will have Arm’s all-new 3nm flagship Cortex-X925 CPU and Immortalis G925 GPU. While Samsung’s decision to adopt the MediaTek chip is uncertain, the Dimensity chip is confirmed to have upgraded CPU and GPU.

Back in May, Arm introduced a flagship Cortex-X925 core, a Cortex-A725 performance core, and a refreshed Cortex-A520 efficiency core. As announced during the unveiling, the company revealed the target frequency of the X925 is 3.6GHz and higher.

Based on 5th Gen Arm GPU architecture, Immortalis-G925 is Arm’s latest flagship GPU. It is designed to offer the best gaming and AI experience on future phones. The GPU promises improved performance with reduced power along with ray tracing improvements.

MediaTek is said to launch the Dimensity 9400 platform in the second half. Only time will tell whether Samsung is bringing the Dimensity chip to its Galaxy S flagships. We may have some authentic information regarding the rumors when Dimensity 9400 goes official.

Samsung fans will prefer buying MediaTek Galaxy phones over Exynos ones. The company may partner with MediaTek to have a custom variant of its flagship chips for Galaxy. Notably, Qualcomm also provides special “for Galaxy” Snapdragon SoCs.
