Sort of - with any card, you will never get that full amount because of the operating system, which is likely using GPU memory (additionally, applications such as your web browser are likely using the memory as well). On the other hand, you can exceed the amount of GPU memory (using virtual memory, either via the drivers or a hand-made solution), but depending on the amount of thrashing it can slow things down greatly.
- jacquesm 12y agoI don't think that answers his question. It has nothing to do with the OS, browsers, virtual memory or trashing but it has to do with the fact that 3.5G of the 4G is directly available but the remaining 512M is only accessible through an indirect (and therefore slower) path as per the article.
