My laptop is having the i7-4700MQ CPU, and I am okay with it. I have 16GB RAM and using SSD, so the performance is better compared to when I was using the original HDD.

 

All else upgraded, the only component left is the CPU, and as per the manual, there is the i7-4900MQ final upgrade.

 

Intel® Quad Core® i7-4700MQ 2.40 GHz processor (SC turbo up to 3.40 GHz; 1600 MHz FSB, 6.0 MB L3 cache, 47 W)

Intel® Quad Core® i7-4900MQ 2.80 GHz processor (SC turbo up to 3.80 GHz; 1600 MHz FSB, 8.0 MB L3 cache, 47 W)

 

The TDW is the same, 47W, so this upgrade should pose no issue on the heat generation or power consumption. Otherwise, I stand corrected.

 

So with that out of the way, all I see is the speed gain and the larger cache. But before doing the upgrade, I still would be comfortable posing this question: is it worth the upgrade at all?

 

Do let me know of the good and bad points. Thank you.

Luckily your machine is one of the last machines which you can replace Processor/CPU. It is up to you depending on the cost. How much for only 0.4GHz and you are right with 2 MB more cache.

 

For experimental I would do. Do you have another machine to use if something went wrong ? Page 74 of the following manual shows you how

Thank you Banhien.

 

I can find some used CPU units to minimize the cost impact. And the additional 0.4 GHz and 2 MB cache could spell the big difference in Windows. Yeap, Windows. I find that in Ubuntu Linux 20.04, Even the lowest configuration would suffice, but not for Windows.

 

Thanks for pointing me to the guide in the manual, but I have disassembled this machine by simply following some Youtube videos. But the manual would be of big help in case of doubt.

 

And yes, you are right. I am more of the curious type, but I am also cautious. That is why I posed this query in case there is something that I am missing before the change.

 

I will keep the i7-4700MQ unit just in case things don't work out right. And yes, I have a few other machines to use as back up. 

 

Thank you once again for your quick reply. Kudos!

A couple of days back, I got the CPU upgrade unit: i7-4910MQ. Yes, I opted for the last in the series.

 

And for an additional 0.4 GHz base speed, I immediately noticed the faster boot time and loading of applications.

 

For how much? US$140.

 

So for that small price to pay, literally, I am happier with my old laptop which is now way much better than when it was using the i7-4700MQ processor. All that is needed is to tweak ThrottleStop to prevent overheating. All in all, I am very, very satisfied with the upgrade.

 

I am adding this to the post in case somebody is thinking of doing it, and wondering for what benefit. I'm one to say, "Go for it!"
