HIS Radeon R9 390 IceQ X2 OC 8GB Video Card Review

Videocards/VGA Reviews by stefan @ 2015-07-25

The technology incorporated inside the R9 390 GPU is not new but is based on the Hawaii (now baptized Grenada), with the same shader count, texture units, ROPs and so on. The manufacturing process is also still 28nm but there are minor improvements which allow running the card at higher speeds and the memory quantity has been doubled, from 4GB to 8GB. Since the HIS R9 390 IceQ X2 is marketed as a pre-overclocked card, the GPU clocked has been raised to 1020MHz instead of 1000MHz stock, while the memory clock remains the same as the OEM AMD cards.

For easier manipulation, HIS has also incorporated a carry handle:

The HIS R9 390 OC needs extra power from one 6-pin and one 8-pin PCI-Express connector:

As we have seen before with 290/290X/390X cards, these feature dual-BIOS capabilities; one of the BIOSes is meant for very quiet operation while the other one is the Standard version, which should be used during gaming:

On the back side of the card we have a backplate which takes like two thirds of the card PCB and helps reinforce it in order to avoid bending:

The cooling system is extending more than the 390 PCB length so the card has a total of 29.7cm:

On the I/O we will find a small grill for hot air evacuation, two DVI ports with HDCP support, one HDMI and one DisplayPort 1.2 port:
