Benchmarks: CPU
Nothing much wrong with the first three results. The longer Blender test does throw up a surprise. We'd expect the motherboard to maintain a 5GHz all-core frequency in this instance. This is not the case as frequency drops to around 4GHz after 30 seconds.
Looking into it further, there is no reason why this should happen. Plenty of wattage is provided for long-term power, but the CPU draws only 205W when under the cosh, compared with up to 280W on full-size boards.
