Hi Popcornmix,
How much of a performance hit should I expect from these new firmware fixes "New firmware (fixes for borderline RPi3+ boards)" ?
I'm again seeing a relativly large degredation in HVEC decoding; using top I'm peeking at 300-315% CPU using #0530
and 360-375% CPU using #0603 for replaying the same video file, I've misses out the versions inbetween because of the problems with schmoo.
I do have a relativley high ram overclock (which is perfectly stable) on my Pi3B+ of 730MHz, as it seems that it's the memory paramaters that are being tweaked by the firmware fix.
arm_freq=1420
over_voltage=3
force_turbo=1
core_freq=560
gpu_freq=510
disable_pvt=1
sdram_freq=730
sdram_schmoo=0x02000020
over_voltage_sdram_p=6
over_voltage_sdram_i=4
over_voltage_sdram_c=4
Thanks for any insight.
Regards, Kevin.
