PCMark 10 7016 points
CT.nl measured 7,016 points in PCMark 10 on the same DeskMini B860 chassis with a Core Ultra 5 235, 32GB of memory, and a 1TB SSD. The CPU differs from this reference configuration, so the result is not used in a score.

Cinebench 2026 multi-core 5073 points
CT.nl measured 5,073 points in Cinebench 2026 multi-core with a Core Ultra 5 235. This is same-chassis evidence only and does not represent the 20-core Core Ultra 7 265.

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.

CPU performance mode Fast CPU, cooling-limited
Robtech found that the 9955HX's strongest benchmark gains appeared after enabling Performance mode in BIOS, but also observed thermal throttling under load and said the multi-core uplift over its 7945HX comparison was modest.

Video encoding behavior No AV1 hardware encoding
Robtech reported that Performance mode did not shorten its brief H.264 encode and only shaved seconds from the longer AV1 test. The reviewer also noted that the Radeon 610M lacks AV1 hardware encoding.

Add-in GPU limits Single-slot, bus-powered GPU
The internal slot provides PCIe 4.0 x8 bandwidth in a physical x16 connector. Robtech says a GPU must be single-slot, shorter than 170 mm, and require no auxiliary power; active blower cooling is preferable in the confined bay.

Full-load loudness 1.7 sone
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.
