The Silicon Shootout: Two Different 3nm Philosophies
2026 marked the abandonment of traditional ARM reference designs by Qualcomm in favor of custom Oryon cores, while MediaTek doubled down on its radical All-Big-Core ARM v9.2 philosophy. We put both 3nm TSMC chips through 40 continuous benchmark runs to uncover the real winner.
1. Architecture Breakdown: Oryon vs. All-Big-Core
Qualcomm’s Snapdragon 8 Elite drops efficiency cores entirely, featuring 2x Prime Oryon cores clocked at an astounding 4.32GHz backed by 6x Performance cores at 3.53GHz.
MediaTek’s Dimensity 9400 counters with 1x Cortex-X925 core at 3.63GHz, 3x Cortex-X4 cores at 3.3GHz, and 4x Cortex-A720 cores at 2.4GHz. MediaTek relies on massive L3 and SLC cache (24MB total) to maintain sustained gaming efficiency.
2. 3DMark Solar Bay Ray-Tracing Stress Test
Under hardware-accelerated Vulkan Ray-Tracing, the Adreno 830 in the Snapdragon 8 Elite edge out the Immortalis-G925 by 11% in initial burst runs, but MediaTek demonstrates superior thermal dissipation in sustained 45-minute sessions.
