Vega absolutely loves bandwidth, it seems to be the primary reason why VII is so much faster than vega 64.Finally got around to properly overclocking my card under water in the full new build. My GPU seems to take a bit more voltage than most, requiring 1209mV at 2101Mhz (which maintains ~2050Mhz in games) -- stock was 1117mV. I also can't seem to do 1200Mhz HBM -- I get artifacts in windows almost immediately -- even at idle temps of like 26C for memory!
Anyways I am getting 10,242 in Timespy, and 24,820 in Firestrike. Seem some people get quite a bit higher with 1200Mhz HBM. It is surprising that HBM clocks matter that much -- surely the card can't really need that much B/W and it must be memory latency improvements with higher clocks..? (+200Mhz on HBM clocks adds roughly as much b/w as a RX 580 has in total!)
