I've finally got my hands on that Dragon Range mITX motherboard, paired it with 96 GiB memory, 2×4TB NVMe and built it into a nice small form-factor case. I've decided to run it under Linux for now and virtualize Windows via KVM. Running the gcc compilation test as before, but with a different version of gcc to be built and the objdump improvements, so not directly comparable. I'll see if and when I can re-do the older tests with the current versions later. | Processor | HW | Core| TDP | Base | Turbo | aTurbo | L1i/L1d+L2 |L3 | Mem | comp | inst | pack | test | tot | ||| | [W] | [MHz] | [MHz] | [MHz] | [kiB] | [MiB] | [GiB/s] | [min] | [min] | [min] | [min] | [min] | |++-+-+---+---+++---+-+---+---+---+---+---| | Xeon E3-1276v3 | 1S/4C/8T | Haswell | 84 | 3600 | 4000 | 3800 | 32/32+256 | 8 |25.6 | 101 |15 | 9 | 445 | 570 | | EPYC 7252 | 2S/16C/32T | Zen2| 120 | 3100 | 3200 | 3200 | 32/32+512 | 128 | 170.6 | 123 | 9 |10 | 200 | 342 | | Ryzen 7735HS | 1S/8C/16T | Zen3+ | 54 | 3200 | 4750 | 3850 | 32/32+512 |16 |75.0 |68 |32 | 7 | 200 | 307 | |++-+-+---+---+++---+-+---+---+---+---+---| | Ryzen 7845HX | 1S/16C/32T | Zen4| 75 | 3000 | 5200 | 4000 | 32/32+1024 |64 |81.2 |43 | 2 | 4 | 122 | 171 | Efficiency wise this (expectedly) doesn't quite reach the level of the miniPC for low and medium load, hovering around 23W at idle under Linux and 60W with the Windows VM started and idling, peaking at about 130W under full load, which makes it slightly more efficient than two miniPC for this scenario. Virtualization seems to consume around two cores with high filesystem activity, so maybe bare-metal via dual-boot would help a bit. I can't test direct hardware passthrough for disks at the moment, which might also help.

The Phoenix mini PC are starting to appear right now, about 15%…20% more performance for about 150€…200€ higher price (about 40…50%) right now. Still waiting for Dragon Range, first teasers have popped up, so I think it'll be available before the end of the year.

I misremembered the code names. The direct successor to the 7735HS (Rembrandt Refresh) are the 7840HS / 7940HS (Phoenix-H at 8 cores and upgraded to 4nm Zen4/RDNA3 and about 15% better performance per Watt); the upcoming 16 core is the 7945HX (Dragon Range, 5nm Zen4/RDNA2). Anyway, I just ordered another of one these to become my new Linux desktop, the first one will stay with Win11 Pro and Cygwin and become my new build box in the coming weeks. I added a 4TB SSD for archival storage last weekend, for now I'll keep the 500GB NVMe it came with for OS and builds as it seems to not limit anything in any meaningful way for now. If it turns out later that it does I'll just switch to a speedy 2TB NVMe later on (I already had one, but that will go into #2 as system / home drive as per the original plan).

Build machines
Since I've impulse-bought a new mini-PC which came with Windows 11 Pro pre-installed, I did some benchmarking against the other two machines I regularly run Cygwin builds on: | Processor | HW | TDP | Base | Turbo | aTurbo | L1i/L1d+L2 | L3 | Mem | comp | inst | pack | test | tot | ||| [W] | [MHz] | [MHz] | [MHz] | [kiB] | [MiB] | [GiB/s] | [min] | [min] | [min] | [min] | [min] | |++-+---+---+++---+-+---+---+---+---+---| | Xeon E3-1276v3 | 1S/4C/8T | 84 | 3600 | 4000 | 3800 | 32/32+256 | 8 |25.6 | 101 |15 | 9 | 445 | 570 | | EPYC 7252 | 2S/16C/32T | 240 | 3100 | 3200 | 3200 | 32/32+512 | 128 | 170.6 | 123 | 9 |10 | 200 | 342 | | Ryzen 7735HS | 1S/8C/16T | 54 | 3200 | 4750 | 3850 | 32/32+512 | 16 |75.0 |68 |32 | 7 | 200 | 307 | The kicker is that it is running at around 9W idle and 70W under full load (measured on primary side), so it's also a lot more energy efficient. It was even cheaper per-core than the used machines I was buying before. Extensibility is of course limited, but works for what I'm going to use. The original plan was to make this my new Linux desktop and replace the 9 year old Haswell I'm using right now and wait until the 16-core Phoenix processors are finally available, but I'll probably have to re-think that.
