haswell is not much of an improvement over ivy bridge, and ivy bridge is not much of an improvement over sandy bridge, there really isn't much benefit of building a winXP system on a haswell motherboard, sandy bridge can be just as fast. Yeah IPC is a just a little bit lower, but it more than makes up for it with better OC potential. The first cpu that it made sense for sandy bridge owners to upgrade to was broadwell-c, but winXP probably not gonna work well on that (though Im very interested in experimenting with it)
p.s. far as I see it haswell has one single benefit over sandy/ivy, and that is AVX2 instructions. Any games/software written to take advantage of AVX2 will see a noticable uplift on a haswell. Sadly I don't have a list of what both uses AVX2 and can run on XP, if there's anything like that. Anyone here know of any examples of software or a game that can use AVX2 and can run on XP?
While it is true there isnt a massive step up between the two there are more improvements there that.
Improved Performance per Watt: Haswell brought enhancements in power efficiency, offering better performance while consuming less power compared to Ivy Bridge. This efficiency was particularly notable in mobile devices, providing longer battery life and improved thermal characteristics.
Enhanced Integrated Graphics (GT2/GT3): Haswell introduced improved integrated graphics performance with Intel HD Graphics 4600 (GT2) and Iris Pro Graphics 5200 (GT3), offering better graphical capabilities for integrated graphics solutions compared to Ivy Bridge's HD Graphics.
New Instruction Set Extensions: Haswell introduced new instructions, such as Advanced Vector Extensions 2 (AVX2) and Fused Multiply-Add (FMA3/FMA4), which allowed for better parallel processing and improved performance in certain applications optimized for these instructions.
Improved Turbo Boost Technology: Haswell refined and enhanced Turbo Boost technology, allowing processors to dynamically adjust clock speeds based on workload demands more efficiently compared to Ivy Bridge.
New Socket (LGA 1150): Haswell introduced a new socket type, which required a compatible motherboard, not backward compatible with Ivy Bridge processors' sockets (such as LGA 1155).
Better Power Management: Haswell processors included more advanced power management features, enabling finer control over power consumption, particularly in idle or low-load scenarios, further enhancing energy efficiency.
Improved Integrated Voltage Regulator: Haswell integrated voltage regulation onto the CPU die, which contributed to better power efficiency and allowed for more granular control over power delivery.
Security Features: Haswell introduced certain security features and enhancements, such as Transactional Synchronization Extensions (TSX), which aimed to improve software performance through better concurrency control.
Those are not my words, its just a copy and paste, but you get the idea that Haswell did offer several features over Ivy bridge CPUs.

Why would you want to dual-boot 32-bit 7 and 32-bit XP? I would probably go for 64-bit 7; if you have any software that doesn't like 64-bit, just run it under XP where it will likely be happier anyways.
It's very likely that I'm misunderstanding something, VivienM, but we have two separate expensive old audio authoring applications we wish to utilize. One of them, as you know, is a 32-application that the audio engineer I'll be working with insists will only run on a standalone 32-bit XP PC ... and it's hard to doubt him because he's the authority on the software ... and he purposely keeps an old XP-era PC around exclusively for the application in question.
There's also a second [also expensive] audio authoring application - with different capabilities - that was written for Win 7. It's not as important to us as the Win XP utility, but it would expand our capabilities, nevertheless.
Quite honestly, I was thinking that one could not run a 32-bit Win OS on one storage drive and a 64-bit Win OS on another while connected to the same mobo. I guess it's the whole thing about memory allocation that's making this confusing for me. Would you mind giving me some clarification in this regard?
If it's possible to load Win XP x86 on one storage drive and Win 7 (x64) on the other, that would be a great news! If this is true, does this also mean that I would be free to add ... say 16GB or more RAM ... to the system? Man, I've got my fingers crossed about this.
It wouldnt matter what the reasons behind it are. You want to use that software and you want to run it on Windows XP just because you want to can be as valid a reason for it all as because it will only run on XP.
Then you come to the Windows 7 software, well thats a whole new problem, and Im not so sure if that doesnt count as "project creep" because wanting to dual boot isnt going to make the solution as easy as it could be.
There is a way to do what you want to do. I wouldnt worry about things like how much RAM is installed in the system though, its just not going to matter to the lesser of the two because it /PAE switch doesnt work how people think should work, and adding more RAM to XP doesnt cause it to become unstable like it doesnt in Windows 98.
Why would the operating systems need two different drives to boot from? You can just dual boot WinXP and Win7 from the same hard disk then use another hard disk for storage.
Yes XP can live on a system with 16Gb of RAM, not only that it will address it all, it just wont use it in the way you think it will. But its /PAE switch will allow it 36bit memory addressing which is upto 64Gb of RAM.
On pressing the power button you can chose which OS to boot into, you can set either OS as the default so if you press nothing on boot it will boot that default option.
You can do all that on a system costing £75-£100 these days. OS licences are extra.
