A while ago I saw Chrome had a 64 bit version in beta.

I declined to upgrade thinking it best to wait for the official version.

I installed it the other day, and for the first time, I began to get memory warnings when I opened lots of tabs.

I have 8gb memory and have opened many tabs on the 32 bit version and my memory usage never went above 60%.

With 64 bit, each time I got the warning, memory usage was at 90%. I wasn't opening any more tabs than usual.
 
LOL! And here I thought FF was a memory hog.

BTW, I am running a 64-bit version of FF here, but I know that doesn't really help you. I guess that's what happens with betas.
 
How many are tabs? I have 6 tabs open with my 64-bit version of Chrome and memory usage is at 30% - 2.4 of 8 GB. I have a few extensions installed too.

The 64 bit version is out of beta. I can tell it's snappier than the 32 bit version, I suppose it's all that memory it uses!

OK, I rebooted to take a look at everything. This is Windows 8.1.

Memory usage is 31% with nothing open and everything in my tray exited / closed down.

Open one tab of Chrome to write this and memory usage is 37%. I have two extensions enabled, the rest are disabled.

Six tabs of different websites and memory usage is 43%.

But sometimes I open a LOT more than six tabs. The difference is, I never got a memory warning in 32 bit Chrome and the day I install 64 bit I have gotten it several times.
 
Chrome on Linux is still a hog

OT: The other day I noticed my wife's laptop (with 8 GB RAM) was accessing the disk more than I'd expect. Task Manager confirmed high memory usage by Chrome (32 bit). She had four tabs open in Chrome, the one tab on imgur had consumed 3 GB of RAM all for itself. I looked over the page but couldn't determine what made Chrome eat so much memory, it was a typical static image page with ads on the side. I closed that tab and memory usage dropped by 3 GB.

So now we know why we need so many gigabytes of random access memory in our computers:
- To display time-killing web sites in Google Chrome.
 
- if you downloaded the beta and never uninstalled it, you're still on the beta channel and you should uninstall and reinstall the stable channel release, else you're at the bleeding edge of changes and unpatched memory leaks
- you can't use less memory than you need, so unless you have the exact number and exact same sites open and exact same extensions of the exact same version installed, don't even compare it, flash is continually updated as well, so even then it's apples and oranges
3 - ads rotate so it's even hard to compare day to day since a static ad need way less memory than a full blown HTML5 video auto-play ad or even a flash ad

I have 3 tabs, a bunch of small extensions, and I'm using 1gb but it's DEFINITELY snappier than the 32bit version, and that's all I really care about in the long run.

Same argument about apples and oranges and theoretical vs actual behavior with oil. Performance matters, specs not so much.
 
Just loaded up 50 tabs and I'm only at 37% of 8GB RAM...

Back down to 4 tabs and I'm only at 28%

^ depends on the websites. I duplicated BITOG tabs and memory use didn't increase.
 
^ I thought about that and had a few tabs with news sites that have embedded videos and I still didn't use a high amount of energy. I am running Adblock, so that might be helping. OS is Win 7 Home.
 
Just had a few tabs open and Chrome completely crashed due to memory. Two instances were showing 2.5GB & 3.5GB usage!

If this keeps on happening, I may have to switch back to the 32 bit version.
 
Tried disabling the extensions. No difference.

I'm guessing Chrome 64 is not ready for Windows 8.1. It officially only lists 7 and 8 whereas 32 bit specifies 8.1 as well.

So I'm back to 32 bit. The low memory warning was coming up too often.
 
Just installed 64 bit. While it does appear to use a lot of memory, doesn't seem excessive. Opened over ten tabs each with different website loaded, checked task mgr and highest physical memory usage was 75%. Four year old quad core laptop running Win 7 64 bit with 4 gb of ram.

It is definitely faster than Chrome 32 bit. Seems like a winner so far.
