CPU% Very High Google Chrome Issue?

Old dell xps 15 9550 laptop

i5-6300hq processor

32gb ram

1tb nvme ssd

windows 10 pro



I had mentioned a while back i upgraded this laptop with the new ssd and ram and it started to be faster.


I use chrome and have tons of windows/tabs. Example imagine 6 tabs... but each tab could have 8 windows each etc. It could be more or less.



I then noticed when i was on chrome... the cpu was very high... it spiked to 100% and stayed there for a while... dropped down a bit... but always seemed to go back to to 100% etc. The only time this usually happens i notice is when i do the windows virus scan though


I then restarted my laptop. The cpu when nothing is opened is under 5% usage. As you know when you open chrome... i have it always open from the last saved page etc... it would always spike up to 100%... since well it would open like 50 plus pages sometimes through all those tabs. But every single time though... it would drop all the way back down to 50% or so... but it would not go higher than 80% unless i try to f5 many of those pages at the same time.


Now what i notice was... it kept going back up to 100% in cpu. But not only that... when i check task manager... you see how they have the


google chrome (80) ... the number in the parenthesis... is that how much chrome tabs you currently have opened? Because i notice that number is never right whether i have 20 tabs or 50 tabs or say 100 tabs. But not only that... it kept going back to 100% cpu each time. I then decided to close many of my tabs and only have like 2 or 3 tables... which totaled maybe 20pages. Now... it showed google chrome (101) all the way down to only (80)... which makes zero sense at all. Does the computer think i have 80 tabs opened or something when its no more than 20?


I then decided to close 2 more tabs... and only have 1 tab... and only like two windows on that. Then the cpu drops all the way down. Anyone can tell me why im having these issues?

Right now i have 3 google chrome windows opened... total tabs on each are 2, 6 and 3... so total 11 tabs total.


But on task manager it shows


google chrome (20)



Can someone explain why that shouldn't show (11)?

Because the number 11 doesn't refer to open tabs.

You made the assumption it did and you are wrong.

I have one Chrome tab open right now and show 16 in the parenthesis.

Well i didn't know that.


But why does the cpu go so high and kept going back?

Because of the first 2 lines in your first post.

The move to 32 gb RAM and the NVMe drive are band aids on an aging horse.

You say my i5-6300hq processor is pretty old then? Others mentioned the processor is still decent. I mean... look at ppl with laptops nowadays... i mean do most even have at least the i5-6300hq speed? Because back then i know many ppl buy the u processor series ... so the avg laptop computer processor is better or worst or on par with the i5-6300hq?

What's "average" and what the "average user" has doesn't mean much.

You are not an average user and you are not asking the machine to do average tasks.

Most users of 5 or 6 year old laptops aren't using them to run multiple large monitors and 50 or 100 Chrome tabs.

You might be able to fiddle around and get minor improvements, but the age, graphics capability, and CPU power of that machine is a constant headwind, always working against you. It's not going to get younger or stronger in any respect that would make much difference..........as you can see with the NVMe drive and the RAM increase.

You aren't likely to change the motherboard or the CPU in a laptop and as far as I know you have ruled out a desktop PC. So, you are stuck.

An i5-6300hq is a Skylake processor, certainly not ancient by any means. We have a a core i5-6500k with 32GB of RAM and an NVMe drive and it's been a very solid machine.

This is on my work laptop, but i have quite a number of things open and running and this is what my CPU looks like.
