The deficiency that AMD has regarding memory seems to carry out to their GPUs, with either memory utilization being low or uarch being inefficient in case of Fury parts.
That as a statement doesn't even make any sense. If you understood how GCN works from a threading model you would understand fury's issue. Fiji in all likelihood is a horrible stopgap created by the poor performance of 20nm and AMD not backporting 20nm design to 28nm ( there is amost nothing in fiji that doesn't exsist in another 28nm part). Memory bandwidth and utilization isn't an issue, if anything memory size appears to be far more of an issue.
i dont see "only" 3000mhz DDR4 as an issue especially if you can take fast ram run it at 3000mhz and reduce CAS. Low ILP miss cares about latency in NS and nothing else. i would be surprised if there a very many real world workloads that dual channel 3000mhz memory will be the bottleneck to a 8 core chip with 16mb of L3 and "only" 256/128 bit load store a cycle.
