Q1- Will the R9 Nano be offered as a reference model only or will AIBs be allowed to offer custom models?
Yes, 3+ months later.
Q2- Can you talk a little about overclocking on the Radeon R9 Nano?
Sort of, because of board power, it may be limited. Targeted at power efficiency. Can overclock, increase power limit, increase clock, but limited by 175W total board power. Wide engine ran at low speed for more efficiency. Up to 1000MHz means it optimizes the frequency based on needs and applications. ~900MHz for gaming. FurMark would likely be lower. 500MHz Memory, can’t modify it officially, won’t be officially supported to be overclocked either.
Q3- In your hot chips 2015 presentation, you showed the Fiji chip has 4 ACE Engines compared to 8 as shown in the previous slides, is it actually 4 ACEs on Fiji?
Q4- Price?
$649
Throttled at 85C. ~75 C at typical loads. 175W board power.
Cooler looks less than it actually is. More efficient and advanced than it looks. Fans mounted into shroud No 3D CAD drawing for Nano. Can’t remove shroud without removing fan, though fan mounts can be made!
Not enough cooling? FAR FROM TRUTH
Dedicated heatpipe for VRM’s. Industry first for OEM. Fins are horizontal. Helps exhaust air out the back of the card and maintain positive air pressure even with an axial solution. Hybrid vapor chamber/heatpipes, Flattened heatpipes on the whole underside of the heatsink. Vapor chamber over ASIC itself.
