SpikeBench Results
On this page you will find results of SpikeBench Benchmark executed on different hardware platforms. Please note that not all of the tested platforms support memory bandwidth reporting by the CPU. For those platforms, memory bandwidth is roughly estimated by SpikeFun and noted as '(est.)'.

* Due to slim thin design of the laptop and the significant thermal design power (TDP) of the CPU (45W) and the fan cooling strategy optimized for silence, after ~20 seconds, system will undergo heavy CPU throttling and reduction of performance by approx. 15-20%. After ~1 minute, fan will ramp up to full speed and throttling will stop, indicating that the laptop has adequate thermal headroom but due to the prioritization of low noise cooling it is not able to use all of its thermal removal capacity immediately.

* Due to slim thin design of the laptop and the significant thermal design power (TDP) of the CPU when compared to the laptop size (35 Watts), one of the CPU cores cannot remain in the highest P state without resorting to thermal throttling. Performance without throttling is ~15-20% better on average.
