Well, like so often you heard hogwash. It has the big advantage of not only supporting more than 2gb per process, but also more than 2b TOGETHER - which is the harder limit. In fact, running a 2gb process on a 32 bit machine leaves little wiggle room for file caches, while running a 2g process on a 64 bit machine leaves tons of.
Unless the system is very little stressed, the memory barrier makes 32 bit OS level wise just a bad install. Heck, I write that on a virtual machine running visual studio - with 8gb memory because it really helps debugging large stuff.
I think that software I'll run on it is 32 bit, so it'll run in emulation
Ah - now you spread bad things, too. No emulation, 32 bit execution is on all decent processors 8not ccounting in Itanium) as fast as 64 bit.
But what if I had the 64 bit version of the software?
Depends. For most software it makes no sense. Depends whether teh softawre can / makes use of more than 2gb memory. But even if not - the OS may.

好吧，就像你经常听到的废话一样。它的一大优势是不仅支持每个进程超过 2GB，而且还支持超过 2b 的总量——这是更严格的限制。事实上，在 32 位计算机上运行 2gb 进程为文件缓存留下的回旋空间很小，而在 64 位计算机上运行 2g 进程则留下大量回旋空间。
除非系统压力很小，否则内存屏障会使 32 位操作系统级别的安装变得很糟糕。哎呀，我在运行 Visual Studio 的虚拟机上编写了这个代码 - 具有 8GB 内存，因为它确实有助于调试大型内容。
啊 - 现在你也传播不好的东西了。没有仿真，32 位执行在所有像样的处理器上（8（不包括安腾））与 64 位一样快。
视情况而定。对于大多数软件来说，这是没有意义的。取决于软件是否可以/使用超过 2GB 的内存。但即使不是 - 操作系统也可能会。
