Not that miners care about stuff like this but DNR is Carsen Klock's newest, soon to be abandoned scamcoin - as it is his signature move after years of not releasing coins or maybe doing so anonymously. Doubt it though, considering his massive ego.
He released dozens of shitcoins which he all abandoned after the initial pump...
But he certainly evolved from shit like Carsencoin [COCK]: https://bitcointalksearch.org/topic/preann-carsencoin-cock-low-025-pre-mine-launched-720684
That means the algo is either ASIC friendly and that it's highly optimized and using the cards to close to their full potential.
A lot of people get that wrong. A hotter card on ceartain algos means the cuda cores are working hard and aren't waiting
on memory. That's a good thing, sort of. Such compute intensive algos are easy to implement in ASIC. The only thing
preventing it is demand. All of these algos that reshuffle sha3 functions are likely to get ASICs eventually if the coins that
use them are successful.
Moving from CPU to GPU to ASIC improves compute performance by orders of magnitude, compare a CPU with 8 cores vs
a GPU with 2000. Memory capacity and bandwidth can't keep up with the number of cores on a GPU so on algos that are
memory hard the cores sit idle much of the time waiting for data from memory, and consequently run cooler.
