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 ][

Kids these days! Fortran loaded from punched cards to an IBM 650, running 12AU7 vacuum tubes and a rotating drum memory.
 
And not sure about this model....

So does it mean there is no successor to the AC88U? ie. AC89U?

No, it simply means that they don't have anything to announce yet.

Traditionally, Asus tends to make most of their announcement at Computex rather than CES. You'll note that the only press event they had at CES was to announce two phones.
 
That new web interface they have with the GT-AC5300 looks pretty damn cool. I like all the graphs, charts and numbers.
 
Yeah the interface does looks nice.....could do with buying out netduma though...if they are serious about being pro gamer.

last attempt was nothing more than a gimmick
 
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
And nice to see the die-shrink to 28nm, so it should run a bit cooler...

Routers don't have to shrink as hard as phones. They're actually growing bigger every year but so do phones..
 
why not exactly?
it has nothing to do with the size but the performance / power use
we pay more for some routers than most phones
they run 24/7 a 14nm cpu is going to use under half that of a 28nm cpu power wise and perform better

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..

FWIW, the long pull on chips like this is not the CPU cores, as these are commodity ARM functional blocks, it's the switch element, which is broadcom's custom IP block.

(RPi3's BCM2710 is still on 40nm, again, long pull there is the videocore GPU, not the arm cores)

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.

Apple's A9 is on both 14nm and 16nm (taped out twice for two fabs, TSMC and Samsung) - imagine the cost there (and twice the validation work as well)
 
Tossing some hard numbers for Cortex-A53 vs. Cortex-A7 - nice to see as both are on the same geometry node - 40nm, and exactly the same rest of board config...

Why this is relevant?

Cortex-A53 @ 1.2GHz is pretty close to Cortex-A9 at 1.0GHz

Broadcom's new chip is on Cortex-A53, QC-Atheros chip is Cortex-A7, so this is a valid test for the CPU cores if not the ethernet functional block - but there, QC-Atheros and Broadcom are roughly similar (within std deviation - both are very good)

TL;DR - Cortex A53 wins here...

Code:
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.

All this talk the biggest thing I want out of my home router is more horsepower.

I find myself using VPN more and more being that I am now on FiOS (150/150) from Comcast (150/10... yes 10... TEN! With ZERO options to get anything faster <spits on Comcast>).

Would love to know if there will be Merlin support for the BRT-AC828. Mostly because out of the box it is dead to me without OpenVPN server support.

No, for multiple reasons, but the main one being the BRT-AC828 is not based on Broadcom.
 
ASUS GT-AC5300: https://wikidevi.com/wiki/ASUS_GT-AC5300 ;)
• CPU: Broadcom BCM49408 @1.8GHz Quad Core
• RAM: 1 GB (DDR3), Flash: 256 MB (NAND)
• WLAN: 3x Broadcom BCM4366E (4x4 802.11abgn/ac)
• WAN: 1x GbE, LAN: 8x GbE, USB: 2x USB 3.0

Wikidevi often bases their entries on pure speculations rather than hard fact. When they list the specs of an unreleased device, don't blindly trust what they publish. I remember one case where the pre-release specs they posted was different from the pre-release sample I actually had in hands.
