I've finally got my hands on that Dragon Range mITX motherboard, paired it with 96 GiB memory, 2=C3=974TB 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.
