Laptop processor speed

[Raymichi]

A HP 15-dw1309nia Latop, core i5 10210U processor with product No. 4220EA#BH5 has processor speed of 1.6 -4.2GHz stated on HP portal, but physical inspection of system property shows processor speed of 1.6 - 2.11GHz.

How do I explain this

@Raymichi,

Welcome to our HP User Forum!

The HP portal has it right according to: https://ark.intel.com/content/www/us/en/ark/products/195436/intel-core-i510210u-processor-6m-cache-u... (Processor Base Frequency: 1.60 GHZ, Max Turbo Frequency: 4.20 GHz), but please be advised that according to the intel link, quote: "Max Turbo Frequency is the maximum single-core frequency at which the processor is capable of operating using Intel® Turbo Boost Technology and, if present, Intel® Turbo Boost Max Technology 3.0 and Intel® Thermal Velocity Boost. Frequency is typically measured in gigahertz (GHz), or billion cycles per second."

Intel® Turbo Boost Technology is activated when the Operating System (OS) requests the highest processor performance state (P0). The maximum frequency of Intel® Turbo Boost Technology is dependent on the number of active cores. The amount of time the processor spends in the Intel Turbo Boost Technology state depends on the workload and operating environment.

Any of the following can set the upper limit of Intel® Turbo Boost Technology on a given workload:

• Number of active cores

• Estimated current consumption

• Estimated power consumption

• Processor temperature

When the processor is operating below these limits and the workload demands additional performance, the processor frequency will dynamically increase by 133 MHz on short and regular intervals until the upper limit is met or the maximum possible upside for the number of active cores is reached.

Unfortunately, reading the fine print, so to speak, the Intel Turbo Boost feature may be system managed and you may not be able to enable or disable it...

If your laptop is able to have Turbo Boost enabled, here's how you do it:

1. Press F10 -access BIOS
2. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Performance Options > Intel (R) Turbo Boost Technology and press Enter.
3. Select a setting and press Enter.
   1. Enabled—Enables the logical processor cores on processors supporting hyperthreading technology.
   2. Disabled —Reduces power usage and also reduces the system’s maximum achievable performance under some workloads.

Hope this was helpful.

Kind Regards,

Your explanation is very helpful and well understood, but I want to justify that what shows on the system properties (Intel Core i5 1.6GHz to 2.11GHz) is same as stated on the HP site.

Why showing 2.11GHz instead of 4.2GHz with Turbo boast as stated on the HP site.
