Build machines

[Achim Gratz]

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.

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).

Achim.

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.
