Not sure if this is the proper place for this, but I did extensive searching on this topic before and got no results. So I did my own testing.
Hardware:
Amd Ryzen 3 3200g APU
16gb 3200 Mhz Ram (corsair LPX c16)
B450 I Aorus Pro Wifi Motherboard
other:
Stock cooler, 2tb nvme intel 660p
Linux:
Ubuntu 21.04
Linux 5.14.2-rt21 SMP PREEMPT_RT
BIOS:
C-states disabled, SMT disabled (no HT anyway), SMP disabled, AMD coolAndQuiet Disabled, 3800Mhz cpu clock (overclock), 3200 Mhz Ram clock
Grub:
isolcpu=3
Few other notes. Downclocking cpu and ram seemed to not have any positive effect. Setting the GFX clock to a fixed 1.25 Ghz seemed to both help reduce latency and make spikes less common. Overclocking the CPU slightly actually helped (might experiment more with more aggressive clocks later)
Disabling C-State and Power idle savers Also did not seem to change latency performance in latency tester, but I left them disabled as a 'just-in-case' prevention against spikes.
Latency Results:
around ~13k is worst Jitter for both Base and Servo. Sometimes if you launch latency test right at system boot, the Servo will get locked into a state that its sub 2k jitter. It wiil stay this way until you close Latency test and relaunch.
I have a Mesa 7i92 card that I will do hardware stepping with so these results are more than good I would think. Not as good as my 3700x.
IF YOU NEED improvement and are thinking of running this cpu, the thing I would try with this cpu is disabling the IGPU and installing a gpu into a pcie slot. However, I don't know why you would use this cpu in that case and not just a Ryzen 3100x or similar.
This apu works as a really nice SFF pc. I have it in a INWIN case and it's relatively tiny for a fully desktop CPU pc.
If there is anything I missed, let me know. Thanks for the awesome support guys.
