How Many Cores Do 12950HX CPUs Have?

Section Link

Intel's 12950HX CPUs have 8 Performance (P) cores and 8 Efficiency (E) cores for a total of 16 cores.

The P cores are comparable to previous generation cores. They support Hyper-Threading, which means they provide two threads each.

E cores are focused on adding additional threads in an energy-efficient manner. They take up much less room on the CPU and generate less heat. However, their smaller cache and minimal interconnect capabilities make them more appropriate for offloading background tasks.

The Intel Thread Director handles scheduling between the types of cores. Running a game will primarily use P cores. At the same time, the Intel Thread Director may offload operating system tasks and low priority periodic events to E cores.

Which Operating Systems Can Make Optimal Use of the E Cores?

Section Link

The Intel Thread Director is used to help operating systems determine onto which cores to schedule work.

Currently, only Windows 11 makes optimal use of the Intel Thread Director.

Linux support for the Intel Thread Director will be available in version 5.18, which is expected to be released in the Spring of 2022. Without this update, Linux will typically prioritize P cores over E cores using the less efficient implementation that uses the Turbo Boost Max 3.0 driver.

How Many Threads Does the 12950HX Have?

Section Link

Hyper-Threading is only available on Performance cores. One thread for each of the 8 Efficiency cores plus two threads for each of the 8 Performance cores results in a total of 24 threads.

At What Frequency Does the 12950HX Run?

Section Link

Prior to Intel's 12th generation of processors, CPUs had a single base frequency and max turbo frequency. With Intel's 12 generation processors, the Efficiency and Performance cores use two individual sets of frequency values.

The 8 Performance cores have a 2.30 GHz base frequency and support a 5.00 GHz max turbo frequency.

The 8 Efficiency cores have a 1.70 GHz base frequency and support a 3.60 GHz max turbo frequency.

What Does the HX Suffix in 12950HX Mean?

Section Link
Processor Name Suffix Meaning
H "H" means it's an enthusiast, high-performance CPU, optimized for mobile usage. Unlike high-performance desktop CPUs, these mobile CPUs use a lower base frequency to generate less heat and use less power when less processing is needed. H-series CPUs have better performance than both P and U-series CPUs, but use more power.
X "X" means it's a high-end CPU that supports either limited or unlimited core overclocking, depending on the model number.

The 12950HX model name has an X suffix. K and X-suffixed mobile CPUs can be overclocked with a compatible laptop.
