Data comes from HUAWEI lab tests, by comparing the CPU performance of the HUAWEI MateBook B3-420 (11th Gen Intel® Core™) with that of its predecessor in multi-core benchmark tests. Performance data may vary depending on the specific product and testing conditions.
2.4 Gbps is the theoretical maximum speed (data from Intel). This feature only works with routers that support Wi-Fi 6. The network speed increase data comes from HUAWEI lab tests, by comparing the HUAWEI MateBook B3-420 (11th Gen Intel® Core™) with its predecessor HUAWEI MateBook B3-410 (10th Gen Intel® Core™).
Performance Mode can only be activated when power supply is sufficient. It is not enabled by default. Once activated, CPU and GPU performance is instantly increased. This may cause the surface to heat up and the fans to produce more noise.
