I can recognize when a dev is good, and they are.
They are two people, which is a important point for time. Look how i messed up with the CNv8 deadline because i was away at the wrong time. May have had a buddy dev, it wouldn't have happended. Two people specialized on cn-v8 for RX/vega against me, alone, having to support CPU aes, and non-aes, 32 and 64 bits, and GPU... I cannot win.
I may specialize in older cards they don't support, or just give up all GPUs. But +5% is a huge gap, i don't think I can fill it up.
Still need to bench the real hashrate, after all Claymore 11 was also +5% on screen, but -5% on pool. But beating ROCm with OpenCL is hardly possible.
I agree with you JCE .. the cpu miner is what put you on the map & even after the v8 fork i still use it as it give me the best results on my CPU miners even after a h/r reduction & extra power draw.
The v8 fork seems to have favoured the RX & VEGA GPU's as most are now getting v7 hash rates and in some cases even more with the various miners, tweaks & optimizations.
I don't see the point in spending time to give maybey the same or +/- 1%-3% hash rate in an already saturated GPU miner field. Everyone is chasing the RX & VEGAS and completely ignoring the lucrative
older CPU's which in some cased have taken a up to 25% drop in hash rate with intel ,Xeons,AMD & opterons both 32 & 64 bit which i have experienced myself as i mine with all of them.
Many miners have gone offline as it's no longer profitable.
FYI: i mine with RX 570's also and pre-fork claymore's miner was tops for me in hash rate/power draw & stability but on v8 i now use xmr-stak which when run dual thread is giving me a higher
h/r than i was getting on the claymore v7. Power draw is slightly up but its otherwise rock solid & stable so i personally would'nt bother to switch miner to get a 1% - 3% increase in hash rate.
I would hope you will find time to see if miner optimization can reduce the loss suffered by older the CPU's as in truth it is what i want to see now as there are already plenty of GPU miners to choose from.
