Windows XP 64bit was a... oddball operating system, it wasn't just Windows XP but 64bit, there were notable technical differences between 32bit and 64bit Windows XP that can hinder software compatibility (Plus driver support wasn't that particularly good for the 64bit version either).
Windows Vista was when the 64bit version was essentially the 32bit version but 64bit. ie: they're no longer significantly different.
Removal of those would break a lot of software, especially removal of 32bit support. Bye, bye thousands (if not millions) of Windows 95/98/XP games & programs!
One of the big features of Windows is its backwards compatibility.
It's very situational, usually the difference is negligible or better (when they're enabled).
The E cores are termed efficient is because they're efficient in regards to how much physical space they occupy, not in terms of power/performance.
Because power delivery throughout a CPU has been from top to bottom for decades (no idea why they went with this in the first place), Intel is working on inverting this and having power delivered from bottom to top and will see this realized in either their Arrowlake or later generation of Desktop CPU's.
Potentially this inversion of power delivery will enable them to place the memory beneath everything and improve thermal characteristics.
D3DVK implements changes that drastically boost performance for Intel cards.*
SSD's just need good power delivery and cooling, where as a HDD needs those plus a means of dampening vibration for good longevity.
HDD's are no longer a good choice for mobile devices like laptops as an SSD is more likely to survive a fall than a HDD.
SSD's however require periodic supply of power to maintain data integrity (power it on for an hour each year afaik), where as a HDD does not.
Several years beyond the time range they gave...
Right,
