Processor Speed

[EB74]

Hi I am using a laptop with an intel core i7 -1265U processor to run engineering simulation software - the base speed for this processor is given as 1.8GHz but it has a 'Max Turbo Frequency' of 4.8 GHz. I am considering investing in a desktop with a faster processor in order to speed up simulations - but I see that base frequencies are not given for the newer intel processors - and therefore am finding it difficult to make a direct comparison.

Would upgrading to a machine with for example an i9-13980HX processor (Max Turbo frequency of 5.6 GHz) make a significant difference to single core speed?

(single core performance is what counts for the simulation software I am using).

Hello @EB74

Thank you for posting on the Intel️® communities.   

We specified the Base Frequency for our products prior to 12th Generation Intel® Core™, it is no longer a suitable metric to use for comparing the performance of processors from different lines and/or generations. We recommend using multiple factors like the processor base power and turbo frequency in order to evaluate the performance of the processors.

Here you can check the comparison between the Intel® Core™ i7-1265U and Intel® Core™ i9-13980HX

I hope the information helps, thank you for understanding.

Thank you Jose for your reply.

Am I right in thinking that a higher processor base power corresponds to a capability to run at higher CPU speeds for longer periods (without thermal throttling occurring)? 

with thanks,

Hello EB74

Thank you for your reply.

Since the Base Frequency is no longer a point of reference to compare the performance, our advice is to compare other values to always have the best product according to your requirements.

If you need any additional information, please submit a new question as this thread will no longer be monitored.
