Snapdragon 845 is a newly announced Qualcomm ARM system-on-a-chip (SoC) built on a 10nm "Low Power Plus" process. It is the first SoC to implement ARM's new DynamiQ clustering scheme:
The Snapdragon 845 is a large step in terms of SoC architectures as it's the first to employ ARM's DynamiQ CPU cluster organization. Quickly explained, DynamIQ enables the various different CPU cores within an SoC to be hosted within the same cluster and cache hierarchy, as opposed to having separate discrete clusters with no shared cache between them (with coherency instead happening over an interconnect such as ARM's CCI). This major transition is probably the largest to date that we've seen in modern mobile smartphone ARM consumer SoCs.
[...] The Kryo 385 gold/performance cluster runs at up to 2.8GHz, which is a 14% frequency increase over the 2.45GHz of the Snapdragon 835's CPU core. But we also have to remember that given that the new CPU cores are likely based on A75's we should be expecting IPC gains of up to 22-34% based on use-cases, bringing the overall expected performance improvement to 25-39%. Qualcomm promises a 25-30% increase so we're not far off from ARM's projections.
The silver/efficiency cluster is running at 1.8GHz, this is clocked slightly slower than the A53's on the Snapdragon 835 however the maximum clocks of the efficiency cluster is mainly determined by where the efficiency curve of the performance cluster intersects. Nevertheless the efficiency cores promise 15% boost in performance compared to its predecessor.
The Adreno 630 GPU should provide up to 30% better performance than the Snapdragon 835's Adreno 540 at the same level of power consumption. Snapdragon 845 devices can record (encode) 2160p60 10-bit H.265 video, compared to 2160p30 for Snapdragon 835.
