This could include, for example, allowing a CPU to go to a full 135W for a short period of time because the GPU is known to be idle, or borrowing some of the thermal budget from a lightly-loaded CPU and instead spending it on the GPU. By dynamically allocating power between the CPU and the GPU, a system should be able to eke out a bit more performance by making better-informed choices about where to allocate power. So, as the thinking goes, if the two processors are sharing a common cooling system, why not raise their power limits and then them split up the thermal budget of the system in an intelligent manner?Īnd this is exactly what Dynamic Boost and similar technologies set out to do. Because the thermal budget of a laptop is usually greater than any single processor, normal processor TDPs have them holding themselves back more than they otherwise would. In fact, a lot of these designs are potentially leaving some performance on the table, as far as peak performance is concerned. This allows OEMs to design around different average, peak, and sustained workloads, offering plenty of headroom for peak performance while sacrificing some sustained performance in the name of lighter laptops. In practice, this is usually done in order to allow OEMs to build relatively thin and light systems, where the cooling capacity of the system is more than the TDP either of the CPU or GPU alone, but less than the total TDP of those two processors together. Like SmartShift, NVIDIA’s Dynamic Boost is designed to take advantage of the fact that in many laptop designs, the GPU and the CPU share a common thermal budget, typically because they are both cooled via the same set of heatpipes. This is essentially NVIDIA’s counterpart to AMD’s SmartShift technology, which was introduced in the recently-launched Ryzen Mobile 4000 APUs. NVIDIA Dynamic Boost: Dynamic TDP Between GPU & CPU, For Intel & AMDįirst off, we have what NVIDIA is calling their Dynamic Boost technology. These new technologies are separate from the new hardware SKUs being launched today – they can technically be built into any future GeForce laptop – so I wanted to touch upon separately from the hardware itself. Being placed under their Max-Q banner, the company is unveiling new features to better manage laptop TDP allocations, and for the first time, the ability to have G-Sync in an Optimus-enabled laptop.

You can find useful information on how to enable Intel Turbo Boost on Linux in this post.Alongside this morning’s launch of their new laptop SKUs, NVIDIA is also rolling out a couple of new technologies aimed at high-end laptops. In general ACPI support must be enabled in Linux for i7z to show correct temps and Turbo Boost (dynamic multipliers above the default) to work. It scales the CPU multipliers up when only a few cores are active, but ramps down under extreme multi-core load to prevent thermal issues with the CPU. Turbo Boost is P0 state, kind of the opposite of sleep. For more detail see Intel's Power Management for Embedded Apps (pdf). Intel® Turbo Boost technology, a core in C6 is considered an inactive core.Ĭ7 - New, slightly deeper sleep state introduced with Sandy Bridge and later.īe warned that C6 and C7 states are "deep" sleep modes and may have some latency penalties that might not be great for certain types of server workloads. Power Gates are used to reduce power consumption to close to zero. For Intel® Turbo Boost technology, a core in C3 is considered an inactive core.Ĭ6 - While in C6, the core PLLs are turned off, the core caches are flushed and the core state is saved to the Last Level Cache. For Intel® Turbo Boost technology, a core in C1 is considered an active core.Ĭ3 - While in C3 the core PLLs are turned off, and all the core caches are flushed. While in C1, no instructions are being executed. Intel® Turbo Boost technology, a core in C0 is considered an active core.Ĭ1 - halt state. While in C0, instructions are being executed by the core. If it is working, you will see the current frequency change as you add load to the CPUs, due to the multiplier increasing dynamically under load. I7z is a good tool for monitoring Intel Turbo Boost for Intel CPUs that support it (i7 and later) on Linux.
