Maximum H/W features supported in each Windows XP edition?

[Guest]

As I know, there are 5 editions in Windows XP.
- Professional Edition
- Home Edition
- Tablet PC Edition
- Media center Edition
- 64bit Edition

What are the maximum H/W features supported in each 5 XP edition like the
below questions?
1) The maximum supported number of physical processors.
2) The maximum supported number of logical processors (under OS)
3) The maximum supported memory size
4) if Hyperthreading feature is supported or not.

For Windows 2003 Server, I saw the similar information on Microsoft Web Page.
But, I couldn't find such an information for Windows XP.

Anyone willing to share this information with us?

Here is what I know:

Windows XP Professional:

2 physical processors
1 logical processor/physical processor (total: 4
processors max)
Can join a Windows server domain

Home

1 physical processor only
1 logical processor
Can not join Windows server domain

Media Center Edition

Can not be bought as software only. Must be bought with new PC.
2 physical processors
1 logical processor/physical processor
Can not join Windows server domain (version 2005 or greater)
Limited compatible hardware
Can use up to 8 separate TV tuners

Windows 64bit

Still is "beta" version. Regualr (for sale) verison comes out later
this year.
Compatible only with AMD64 and Intel Itanium processors
(NOTE: AMD64 processors can also run Windows XP (Pro/Home) )
Still has limited driver support from hardware vendors



Common to all

HyperThreading -- Logical processors
Support for 4GB of RAM (may need special boot up option)
Starting with XP SP1 -- support for TB hard drive sizes.

In your comments on XP professional,
" 2 physical processors,
1 logical processor/physical processor (4 processors max) "
I think 2 logical processors/physical processor is correct because max 4
processors are supported.

Could you clear the logical processors per physical processor on each edition?


Thanks,

Hi

A single processor supporting Hyper-Threading Technology presents
itself to modern operating systems and applications as two virtual
processors.

So WinXP Pro supports 2 physical processors, that can be seen as
4 logical processors if hyper-threading is available.

And WinXP Home supports 1 physical processor, that can be seen as
2 logical processors if hyper-threading is available.

Pro and Media Center which is a superset of Pro support two physical
chips; Home only one. As Tablet is supplied only on a tablet machine
the point does not really arise, but that is also a superset of Pro.
Each of these physical chips on any version can have multiple virtual
processors in hyperthreading

Max RAM is 4 GB

64 bit I don't know
