Dimensity 9400 Plus vs Exynos 2600: Dedicated Gaming Sheet And Review

Data Review:

Although the Exynos 2600 pushes a slightly higher short-burst peak score (+9.1% in Steel Nomad Light) due to AMD RDNA geometry, its extreme 14.5W power draw and early thermal throttling (61% stability) hurt its real-world gaming score. The Dimensity 9400+ achieves a 59.6% higher MCGI efficiency rating by operating at 11.2W on TSMC’s N3E node and maintaining 82% performance retention.

Formula Breakdown:

• ​Dimensity 9400+ Calculation: (2,850 Peak Score × 82.0% Stability) / 11.2W Peak Power = 208.7 MCGI
• ​Exynos 2600 Calculation: (3,109 Peak Score × 61.0% Stability) / 14.5W Peak Power = 130.8 MCGI

Data Review:

MediaTek’s Tri-port MIPI display engine drives on-device panels up to WQHD+ @ 180 Hz and external output at 8K @ 60 FPS. Samsung caps on-device rendering at 120 Hz and external output at 8K @ 30 FPS. MediaTek’s silicon-level VRR bypasses Android Surface Flinger to reduce input lag by up to 22 ms.

Data Review:

MediaTek drives the 12-core Immortalis-G925 GPU at a high 1.612 GHz clock speed (+64.5%). The Exynos 2600’s AMD RDNA 3.x Xclipse 960 operates at 980 MHz but utilizes wider WorkGroup Processors (WGPs) to achieve 5.21 TFLOPS (+5.3%).

Data Review:

Samsung’s AMD RT V2 hardware accelerators provide superior ray-tracing intersections (+50%). However, MediaTek’s MFRC 2.0+ frame generation integrates directly with the NPU 890 to reduce GPU power draw by up to 40% when doubling frame rates.

Data Review:

Dimensity 9400+ supports LPDDR5X-10667 memory, providing 85.3 GB/s of bandwidth (+11.1%). It combines 12 MB L3 with 10 MB System Level Cache (22 MB total) to feed the GPU pipeline, while Samsung uses 16 MB L3 and a larger 4 MB GPU cache.

Data Review:

MediaTek’s HyperEngine 8.0 and MFRC 2.0+ decouple engine rendering from display output, halving thermal load. Samsung relies on Game Optimizing Service (GOS) and an internal Heat Path Block (HPB) layer to manage thermals.

Data Review:

Dimensity 9400+ delivers smoother frame stability in Wuthering Waves (59.9 FPS vs 57.4 FPS). In x86 PC emulation, Winlator 10.1’s Vortek driver allows the Immortalis GPU to outperform the Exynos 2600 by +40% in The Witcher 3 (42 FPS vs 30 FPS).

Data Review:

Exynos 2600 wins short-burst synthetic benchmarks (+9.1% in Steel Nomad Light). However, under sustained load, the deca-core 2nm GAA layout creates heat hotspots, spiking power to 14.5W and dropping performance stability to 61% after 10 minutes. The Dimensity 9400+ draws 11.2W at peak and holds 82% stability over 22 minutes.
