Answer 1

It's hard to answer correctly and the answer could be figured out only in benchmarks for particular task with particular build.

There are several thing that could allow you to use from 1 to 2 GB of memory:

• Chrome version: because different V8 engines have different memory limits.
• Chrome platform: 32-bit or 64-bit.
• Operating System itself: chrome could be built with different flags for different platforms.
• Again, Chrome version: there are some discussion on the internet about recompiling chrome with some compilation flags that could allow to use more memory, then chrome developers decide to exclude such flags because of some reasons. Who know — maybe they will include them again or will increase default heap size.
• Video memory: in some cases page's content may require some video memory and, if your video adapter has no sufficient amount, Chrome will take it from general memory, which will increase memory usage for the page.

Right now, with 64bit Chrome version 47, on Windows 8.1 I can take up to 1.8GB with one tab, then it crashes.

Update:

As I can see some magic has happened and limit has changed.
For Chrome version 63, on x64 Windows 10 OS, I could allocate up to 3.5 GB memory, parsing a huge JSON string and then displaying it on the page.
The number is taken from Chrome's Task manager and from Process Explorer's Private Bytes metric.
