Does more cores help for running many applications simultaneously?

HopelessNoob · Apr 13, 2016

Hi everyone,

I did a Google search on this and found older articles so I kind of want to get an answer for this day and age. I often like to run many many things at the same time like web browsing with over 9000 tabs VM servers gaming etc etc. I know RAM is a must but was wondering if like a 6 core 5820k or an upcoming zen processor with maybe 8 cores would make a difference than something like a 4 core 6600k or something similar?

Thank you

9000 tabs? How do you get back to the one you need with so many? If 8999 do nothing, then it doesn't matter, but if several are busy and you run a lot of VMs while gaming, then why not consider an i7-5960X? It should meet your requirements.

9000 tabs? do you like having every web page on the internet open at once or what?

If you're using VM's, then in general you'll want to be running a multi threaded CPU. You're VM's would love to run on a i7-5820k vs an i5 anything .

I really hope that is a typo.

I'm just hoping he's a DragonBall fan and not making his poor browser have 9000 of anything going on.

More cores doesn't help if the program does not take advantage of it.
Most programs run happily on dual core and sometimes moving to a quad core does not show any noticeable difference.
Again it depends on how the program/software is written to take advantage of the hardware resources available.

Members, let's get back on track. OP wants to support 9K open tabs unless it's a typo. Don't make fun of him/her. Suggest alternative forms of organization, or tell the OP that memory is more important than cores for multiple tabs, and both are important for VMs.

OP, would you consider getting more than one machine and a keyboard - monitor switch, or using Mouse Without Borders? That's a heck of a strain on a commodity machine.

It would have to be a typo. I have three tabs open in FF with it using 180MB. If we account for the FF overhead and give each webpage a 30MB size (really depends on how much text vs how much flash/java/HTML5 as some sites are massive) then 9000 active tabs would push 263GB of system RAM.

LGA2011 has support for up to 8 DIMMs and DDR4 can do 16GB per DIMM right now making it currently able to max out at 128GB. LGA 2011 supports up to 3 DIMMs per channel but that is only in DDR3 as of right now and only in the C600 series dual socket Xeon chipsets.

Now I could be way off, maybe browsers have the ability to stop tabs from being active but at that point, if it has to reload the page anyways, why keep it open occupying memory that could be used for something else?

it was a dragon ball z reference haha I just meant that I usually have a lot of tabs open. but because of this I'm just assuming that what's more taxing in my system with many tabs open would be the RAM. but a side question is I believe chrome becomes sluggish after I do open a lot of tabs in chrome. with a lot of headroom with RAM and relatively low CPU usage, does that mean that it's an application's fault?
