Cinebench 2026 multi-core 5073 points

Power-envelope constraint 65W chassis class
Intel rates the Core Ultra 7 265 for 65W base power and up to 182W turbo power, while ASRock limits the DeskMini B860 to 65W processors and supplies a 120W adapter. Sustained 265 performance therefore depends on the chassis BIOS limits and cooler rather than the processor's unrestricted desktop maximum.

CT.nl measured 1.7 sone under full load with the Core Ultra 5 235 and its boxed Intel cooler, while idle and light GPU-only work stayed below 0.1 sone. The target 265 and cooler choice differ, so this is not scored.
