Installation
We used a Lian-Li Pitstop T60 chassis for our test bench. It provided us with plenty of space for us to install 2 x Radeon RX 480 and the Cooler Master MasterLiquid Pro 240 AIO. The two cards fitted nicely with enough room between the cards for some airflow.
You’ll need 2 x 8-pin PCIE power cables, one for each card. As for connecting the system to your monitor, only one cable is required. Just connect it to the card closest to the CPU.
Test Bench
For our tests, we used a completely new test rig which comprises of an ASRock Fatal1ty X99X Killer 3.1 motherboard, along with an Intel Core i7-6800K at default clock speed of 3.4GHz, as well as 32GB of ADATA DDR4-2400 ram in quad channel mode.
All tests were conducted at default clock speeds at a resolution of 1920×1080. High or Ultra settings enabled.
| CPU | Intel Core i7-6800K @ 3.4GHz |
| Cooling | Cooler Master MasterLiquid Pro 240 AIO |
| Motherboard | ASRock Fatal1ty X99X Killer 3.1 |
| Ram | 4 x 8GB ADATA XPG Dazzle DDR4-2400 |
| XMP 2.0 profiles | Memory timings : 16-16-16-39 @1.2v |
| HDD | Crucial MX300 – 750GB |
| PSU | Thermaltake Toughpower DSP G RGB 750W |
| VGA card | 2 x HIS Radeon RX 480 Roaring Turbo (8GB GDDR5) |
| AMD Drivers | Catalyst 16.9.2 (Crimson Edition) |

The Radeon Catalyst Drivers
As you can see from the Radeon Catalyst Drivers, both RX 480’s are linked in Crossfire mode with a core clock @ 1338MHz. Memory clock is at 4000MHz.

Pc perspective found Crossfire was a stuttering mess due to frame time variations. Fps does not tell the whole story.
I wonder what games they were testing ?I have tested over 20 CF supporting games in the past couple months and havent found any of them to be a stuttering mess (including some of the latest tittles like Deus Ex ,black ops 3 ,shadow warrior 2 ) ,infact they ran nothing short of an excellent .Of course CF/mGPU will not work on all the games but AMD is working its backside off to make sure as many titles as possible do .
The testing was kind of wrong. First of all, why stock cpu? A powerful gpu setup, especially AMD, need more power from the cpu. Then, CF worth much more within a higher resolution (1440p scales ok, 2160p scales best), not 1080p. And “Monster Hunter Online, NVIDIA and Crytek have joined hands and accomplished this stunning benchmark program.”… no wonder is not scaling well on AMD since are NVIDIA’s hands in it…
I agree… we need more support for AMD!
Re: conclusion of author. The other thing to consider is that you buy one card now and down the line you buy a second (and then cheaper) card as a solution that likely meets nicely your performance needs. Also consider that at higher resolutions, CF can make it playable.
Re: “Stuttering”. This is a bit a red herring. They use apps to measure micro stuttering that you the user don’t notice. It’s irrelevant. Gameplay experience is what matters.
Re: CF support. Here’s the Achilles heel of the solution. Your drivers have to have a CF profile for a game and be supported properly for you to see any benefit.
Crossfire rocks!
