Basically it's a merge between AC88U and AC5300
So does it mean there is no successor to the AC88U? ie. AC89U?

This should probably go in the greybeard thread...
I spent many late nights as a young teenager sorting 6502 assembler* - came in handy later on in life...
* some wise guy will likely ask... so yes, Apple ][

I'm surprised Maylyn hasn't flooded us with photos yet LOL
And nice to see the die-shrink to 28nm, so it should run a bit cooler...
My god whats the AC88U 40nm? 55nm?
my 2014 Exynos Note4 (N910C) is 20nm geez broadcom like the old nodes
they should be launching at 14nm in 2017 not 28nm
Routers don't have to shrink as hard as phones. They're actually growing bigger every year but so do phones..

IIRC, current is on the 40nm node... 28nm is good.
14/16nm nodes are still pretty expensive - which is why only the high end silicon (CPU/GPU) are using it..
CPU/GPU and SoC are totally on different paths of process upgrade. SoC always lag behind a few generations. But as reference point, Huawei's Kirin 950 (2015) was already manufactured using TSMC's 16nm FinFET process.
Quick Study - ARMv7 across Cortex-A53 vs Cortex-A7
--------------------------------------------------
CPU Speed - 900 MHz
Core Clock - 250 Mhz
--------------------------------------------------
DUT's - Raspberry Pi2, Raspberry Pi3
Pi3 has been configured to same core/gpu/cpu/ram clocks as Pi2
/boot/config.txt - this item is added for the Pi3
# edit to underclock pi3 to pi2 clocks
core_freq=250
arm_freq=900
arm_freq_min=600
# end edit
Both DUT's are headless to remove the GPU from any test artifacts

Tests - exploring OpenSSL, gnutls-cli, and Sysbench across different
core architectures. This test is probably the best indicator of
improvements across ARM's A7/A53 as the rest of the HW is the same.

Would love to know if there will be Merlin support for the BRT-AC828.
