Click or the question for details:
TDP stands for Thermal Design Power, in watts, and refers to the power consumption under the maximum theoretical load. Power consumption is less than TDP under lower loads. The TDP is the maximum power that one should be designing the system for. This ensures operation to published specs under the maximum theoretical workload.
Yes, in the 12th Generation and above, the TDP terminology is replaced with Processor Base Power.
The purpose of defining TDP is to provide system designers/integrators with a power target in order to help with proper thermal solution selection.
By the published TDP value. That’s the steady state design target. Designing for anything less for power delivery or thermal solution capability is a decision the system designer must make.
Yes, there are.
Under a steady workload at published frequency, it is TDP. However, during turbo or certain workload types such as Intel® Advanced Vector Extensions (Intel® AVX) it can exceed the maximum TDP but only for a limited time , or
TDP is calculated assuming core and graphics combined, but it's also reported separately for the core and the graphics.
