Chip speed on Intel i7 - 11700T Processor

[Warren26]

Hi all, hoping for clarification on my system please.

I have a Intel i7 as above with Octa core 16Gb  which runs at 1.4GHz which should boost to 4.6GHz when required.

The product description from the vendors states this as does the system spec here on the HP help site.

However the windows system 'about' describes it as '11th Gen Intel(R) Core(TM) i7-11700T @ 1.40GHz 1.39 GHz' and that 1.39 GHz confuses me.

I am running an animation package which calls for

• 2.6 GHz Intel Core i5 CPU or higher
• 8 GB RAM or higher recommended
• 10 GB free hard disk space or higher recommended
• Display Resolution: 1440 x 900 or higher
• Graphics Card: Nvidia GeForce GTX 650 or higher / ATI Radeon HD 5770 or higher
• Video Memory: 2 GB RAM or higher recommended

I have had a few small issues with buffering and I expected this new system to be well over what was required.  Is there any way I can check the processor is actually boosting?  Does it need to be set to boost?

My graphics card is NVIDIA® GeForce® MX350 (4 GB GDDR5 dedicated)

Any information or reassurance would be most welcome thanks

Warren

@Warren26 -- I have a Intel i7 as above with Octa core 16Gb  which runs at 1.4GHz which should boost to 4.6GHz when required.

I think that you mean "16 MByte Cache", not "16 Gigabit Cache".

Is this your processor:Intel® Core™ i7-11700T Processor (16M Cache, up to 4.60 GHz)

That web-page states that it has 8 cores, and 2 threads per core.

My understanding is that the "boost" process will disable some of the cores/threads, to achieve 4.6 GigaHertz on some of the cores.  Switching to "single-threading" speeds-up some applications, such as Windows Update, that do not exploit multiple cores/threads.

> However the windows system 'about' describes it as '11th Gen Intel(R) Core(TM) i7-11700T @ 1.40GHz 1.39 GHz' and that 1.39 GHz confuses me.

Is the "1.40" reported by querying the CPU itself, while the "1.39" (which could be rounded from 1.3850001 or from 1.3949999) is some value that was measured by the motherboard ?

> Is there any way I can check the processor is actually boosting?  

Does the Windows "Task Manager" or the Windows "Processor Monitor" show the current "boost" level ?

Hi

it this this one ?

https://support.hp.com/za-en/document/c07764059

HP Pavilion 27-d1021na PC

16 GB memory; 1 TB SSD storage

Intel® Core™ i7-11700T (1.4 GHz base frequency, up to 4.6 GHz with Intel® Turbo Boost Technology,

to simply answer your question
no, you don't have to do anything
just see this

Intel® Turbo Boost Technology (TBT) is one of the features built into latest-generation Intel micro architecture. It automatically allows processor cores to run faster than the base operating frequency if it's operating below power, current, and temperature specification limits.

Thanks so much for getting back to me Itsmyname

Copied from system settings - I think I should have said 16Gb RAM

Processor 11th Gen Intel(R) Core(TM) i7-11700T @ 1.40GHz 1.39 GHz
Installed RAM 16.0 GB (15.7 GB usable)
System type 64-bit operating system, x64-based processor
Pen and touch No pen or touch input is available for this display

But I understand the RAM is increased virtually to 32Gb via Intel Optane.

Yes the link you provide seems to be my processor.

So if the boost process disables some cores, I need to find out if my software does or does not exploit multiple cores.  Then I need to know if switching to single threading is an automatic or manual process and if manual is it simple or complex ie would I be able to switch just when using that software.

The 1.40/1.39 is from system settings as above.

I have now queried the CPU via Task manager and the speed tops out at 2.75GHz when I attempt the software actions in Cartoon Animator which cause the buffering.  It doesn't mention any boost but the fact that it is above 1.4GHz suggests there is some boosting happening.  Is that correct?

During the software action memory use in Cartoon Animator is 2172.5Mb and in Microsoft edge is 890.5Mb plus all the other backgrounds etc comes to 8.4 of 15.7Gb = 53% of memory being used.  From this it seems that Cartoon animator is using just 14% of the RAM  and the rest is Alexa, McAfee, Dropbox,  Teams, Microsoft Office click to run,  Omen gaming Hub (whatever that is) etc.  So perhaps my problem is simply too much going on in the background which needs turning off.

If this is the case I feel I may have wasted your time.

What do you think?

read my answer above @Warren26 
the boost is activated by default
it is not mentioned in the manager, you normally have the display under processor performance at the top right processor speed, and at the bottom, speed with current boost and next to the base speed, which you normally noticed effectively '' 2.75GHz '' boost

you can possibly reduce the use by disabling unnecessary programs, in order to relieve the processor
but to see if your problem does not come from other things rather

@Warren26 -- So if the boost process disables some cores, I need to find out if my software does or does not exploit multiple cores. 

It all depends on the programmer who has written the software. if that software does not take advantage of multiple cores/threads, then there is nothing to "enable" within that software.  Instead, Windows will always try to use all the cores/threads that are available within the processor.

Windows Update is mostly single-threaded. It can download multiple updates at the same time, but when installing each update, it only does one update at a time.

> Then I need to know if switching to single threading is an automatic or manual process

Neither. It is the software, such as Windows Update, that was designed as single-threaded.

> would I be able to switch just when using that software

No, at least most of the time, because most software does not have a "switch" to enable/disable that technique. If the software has been programmed to exploit multiple cores/threads, it will do so, all the time.

> all the other backgrounds etc. comes to 8.4 of 15.7Gb = 53% of memory being used. 

Good. If you have a desk-job in a company, it is good if the top of your desk has enough surface space to keep all your reference books & papers & computers & keyboard & mouse occupying only 53% of the available surface -- you can work "optimally" -- no need to close a book, and store it onto a bookshelf, to make room for some other book to be pulled from the bookshelf to be placed on your desk. such movement of the books is inefficient.  Same for your RAM, when only 53% of it is required.

That is a very helpful explanation thank you for explaining it to me.

I will stop any unused large memory consumers in startup anyway but will let the rest run as I now understand this is not an issue.

Thanks again
