The Surface Book 2 features a full-body magnesium alloy construction. [3] The device comes in two distinct portions: a tablet that contains the CPU, storage, wireless connectivity and touchscreen, and a hardware keyboard base that contains a high-performance mobile GPU, supported by its own active cooling system.
ACPI 1.0 (1996) defines a way for a CPU to go to idle "C states", but defines no frequency-scaling system. ACPI 2.0 (2000) introduces a system of P states (power-performance states) that a processor can use to communicate its possible frequency–power settings to the OS. The operating system then sets the speed as needed by switching between ...
Surface Book was announced at the Windows 10 Devices Event by Microsoft on October 6, 2015, alongside the Surface Pro 4, and went on sale shortly thereafter. [7] At the announcement, Panos Panay, corporate vice president for Surface Computing at Microsoft, initially presented the device as a laptop and positioned it as a competitor to the MacBook Pro, before revealing that it was a hybrid ...
On October 26, 2016, Microsoft unveiled an additional configuration, called the Surface Book with Performance Base, which has an upgraded processor and a longer battery life. [57] The second generation Surface Book 2 was announced on October 17, 2017, introducing an upgraded ceramic hinge for stability, and lighter overall weight distribution.
Devindra Hardawar of Engadget, who gave positive remarks to the predecessor Surface Book 2, notes similar problems with the lackluster CPU performance in 2020, [22] "The Surface Book 3 features Intel's quad-core 10th generation Ice Lake CPUs, which max out at a 3.9GHz Turbo Boost speed. Those chips also appear in the Surface Laptop 3, an ...
CPU throttling, computer hardware speed control, also known as dynamic frequency scaling; Bandwidth throttling, used to control the bandwidth that a network application can use; Throttling process (computing), software speed control
The Time Stamp Counter was once a high-resolution, low-overhead way for a program to get CPU timing information. With the advent of multi-core/hyper-threaded CPUs, systems with multiple CPUs, and hibernating operating systems, the TSC cannot be relied upon to provide accurate results — unless great care is taken to correct the possible flaws: rate of tick and whether all cores (processors ...
A variety of rate limiting techniques are applied in data centers using software and hardware. Virtualized data centers may also apply rate limiting at the hypervisor layer. Two important performance metrics of rate limiters in data centers are resource footprint (memory and CPU usage) which determines scalability, and precision.
