A 2006 Acer E380 Desktop PC AMD Athlon 64 X2 4200+ (DualCore) 2GB RAM 250GB 5400 RPM on an EliteGroup MCP61PM-AM (Socket AM2) Mainboard Not much fun, but it works.
But then you can actually use it, just like I'm using right now the turion x2 of the same age (which has a CPU likely a bit slower than its desktop cousin)
interesting thing is that w11 runs faster than w10 video in 4k 60 fps on w10 it ate about 20% of cpu whereas on w11 it took about 8% of cpu it's just much more optimized w11, I used the same driver and the same browser in the test what do I think? it says? What did MS do to make w11 much better in this CPU area?
For sure that's an area where there is room for optimizations (and possibly also for dirty tricks, given decoding videos can be done faster at the expense of quality) Probably most of the magic is inside msmpeg2vdec.dll, not in drivers.
I7 x980 extreme (2010 release) overclocked to 4.2ghz can push to 4.5 easily. asus x58 p6x58d-e LGA1366 chipset 32 gigs of DDR3 WD blue nvme ssd To get the full speed on the NVME, I used a PCI-E slot so I can get FULL speeds even with older motherboard. Normal SSDs were being bogged down to incredibly slow write speeds using traditional SATA slots. I used an SSD for a boot drive to boot into cloverboot, then automated it so it was a seamless boot. As you cannot get NVME to boot on PCI-E directly. Fun little project.
Of course, SATA bus speed is limited to 6Gb/s at the highest. NVME has direct access to the other hardware and can bypass CPU processing (which is a bottleneck).
My oldest machine running W11 is a 2008 custom build desktop with the following specs: Mobo - GIgabyte 780G CPU - AMD 4800+ RAM - 3 GB HDD - 500 GB GPU - ATI HD 4670
That question basically means nothing. Win10 is actually 8/9 different OSes 1507/1511/1607/1703-1709/1803/1809/19xx/20xx (let alone Server 2022) Win 11 is (at least) four different OSes 22000/226xx/253xx/259xx) So it depends on what you compare. There is actually way more difference in speed between 22000 to 25xxx (especially 259xx that likely is the first incarnation of Win12) than the difference between 1904x to 22000
A 2008 Compaq 615 Laptop by HP CPU: Athlon X2 Dual Core QL-66 CPU RAM: 3GB DDR2 SSD: 120GB Latest Windows 11 23H2 (script+bypass) and BIOS then updated from 2009 to 2011 version, using the Win7 (64bit) exe. Not much fun either, but it works.
