ASUS EA-AC87 (Ver. A1) 5GHz AC1800
World 1st 
After meeting with ASUS 2 months ago, finally the EA-AC87 is here !! Thanks ASUS Malaysia for delivering the test unit 
DualCore Quantenna QT3840BC SoC @500MHz, 5GHz-only MIMO 4x4 @1734MHz, design for 5GHz Media Bridge --> Currently World 1st of such device !!

I still remember the previous dualband EA-N66 Media Bridge device, it's MIMO 3x3 with really nice Pyramid design, comes with 1 gigabit port. ASUS continue to design high-end Media Bridge with higher bandwidth, this time another bridging device with 4 antenna MIMO 4x4 single band 5GHz only, include 5 gigabit ports for more connection. Straight forward square shape design, equipped with 4 rather unusual short and flat antenna, slightly bigger body size, maintain the usual black Knight surface design with glossy finishing around it. No more fancy look, this is a serious 5GHz-only bridging work horse. In fact it looks to me a bit cute, it's like a little 4 arms or legs robot toy 
Media Bridge Tests
Lined up some toys : RT-AC68, RT-AC87 & the latest RT-AC3200, to test respectively and see how this robot can perform 
My testing setup & scenario as follows :
and the result :
| Tests | LANSpeedTest | iperf | ||
| Writing MB/s | Reading MB/s | Lo/Hi Mbps | ||
| RT-AC68 | 55.8 | 56.9 | 520 | |
| 51.1 | 56.8 | 536 | ||
| RT-AC87U | 65.8 | 64.6 | 844 | |
| 63.6 | 65.1 | 885 | ||
| RT-AC3200 | 59.1 | 53.6 | 572 | |
| 59.5 | 51 | 601 | ||
Impressive, by far the fastest & highest wireless bridging speed I've ever tested so far
Especially bridging it with the AC87U as shown above, deserve to be named as the EA-AC87
On the other hand, I'm quite surprised with the AC3200 result, I was hoping either similar like the AC87U or even better. However, the bridging result on AC3200 is only slightly better than the AC68.
Hmmm, the AC3200 still new, looks like the firmware/driver still need further tuning/adjustment ...
Media Bridge Test - iperf between 2 XPEnology ~Synology NAS
After the good test result with AC87U above, I decided to run another round of iperf test purely between 2 XPENology ~Synology NAS (based on ASRock Q1900 mobo with DSM DS3615xs package). My test setup & scenario as follows :
and the test result :
Throughput hitting around 900Mbps , almost to the 1Gbps limit, very geng-ah (strong!)
This is 1 device definitely worth to use as Media Bridge, a must-have AC87U companion
