MultiGPU (Crossfire DX11) Benchmark - Final Fantasy XIV Stormblood Benchmark. RX Vega/FE Results please?

Hello,

 

I was recently investigating purchase of two RX Vega LE / FE Cards for a new AMD Threadripper Build.
I have decided against purchase of the RX Vega LE/FE as I need Windows 8.1 64bit OS Support.

MultiGPU support (two cards) has just been added for Vega Cards with the recent Crimson ReLive 17.9.2 Drivers.
I thought I may as well share the data I generated whilst investigating Vega purchase.

 

As you will see from my data below, I get great scaling at 4K UHD with a pair of R9 Nanos on my i7-4790K based system.
I see no Crossfire related flicker issues at all in the benchmark. It runs really well.

 

The release notes for the new Vega MultiGPU driver can be found here: Radeon-Software-Crimson-ReLive-Edition-17.9.2-Release-Notes

Note that the term MultiGPU is AMD new marketing term to cover Modern MultiGPU (DX12) technology and older Crossfire (DX11).
More information can be found in the following article: Radeon RX Vega graphics cards get 2-way multi-GPU support in Radeon Software 17.9.2 | PCWorld


Today I will post the Crossfire (DX11)  data I generated running the Final Fantasy XIV Stormblood benchmark
I discovered the Final Fantasy XIV Stormblood benchmark thanks to  whiskey-foxtrot , he used it to test the performance of his  Watercooled RX Vega 64 Cards on his outstanding Oscar Mike  build.

 

I tested Crossfire Performance running on the following System:

 

CPU = Intel i7-4790K CPU. Running at a 9% overclock from Stock. (4.6, 4.6, 4.5, 4.5 GHz for 1,2,3,4 cores active).
GPU1 =  Powercolor AMD R9 Nano (Fury X) with 4GB HBM.
GPU 2 = XFX AMD R9 Nano (Fury X) with 4GB HBM.
     I ran the tests using AMD Crimson ReLive 17.9.1 Driver.
     Both R9 Nanos were running with Max Fan, Temp and Power Targets, and a 5% GPU CLK Overclock, to give 1050MHz max.
     I was unable to Under or Overclock the HBM memory in these tests.




     No third party OC Software (Such as Sapphire Trixx or MSI Afterburner) were installed on my System during the tests.

Motherboard = Asus Z97 Deluxe Motherboard with NFC and Wireless.
RAM = 32GB Corsair Ballistix Tactical LP DDR3 1600MHz.


 

I ran the tests on Windows 10 64bit OS with latest Patches as of 15 September 2017.

The Windows 10 64bit  OS installation was checked, and passed all tests  following fresh AMD Crimson ReLive 19.9.1 Installation.

 

I would be grateful if people with RX Vega / Vega FE running in Crossfire could run the Final Fantasy XIV Stormblood Benchmark and post their results to this thread please.
It would give me some idea how Crossfire DX11 on RX Vega / FE cards compares to my existing Dual R9 Nanos.
