XFX R7 250 Ghost 2.0 Closer Look:

The XFX R7 250 is built on the Volcanic Islands GCN architecture, succeeding the Southern Islands/Sea Islands(OEM-only re-badge). The core is manufactured on a 28nm fabrication process. This design supports Microsoft DirectX 11.2 and Bullet physics. Its 1GB of GDDR5 communicates through two 64-bit memory controllers. The top of the card has a large 90mm impeller off-center on a flat plastic cover, the XFX name at the rear. At the center of the impeller is an XFX Graphics sticker. Since this design consumes little power — the PCI Express x16 slot provides up to 75W — the circuit board design should be relatively simple.

Flipping the card over shows that the circuit design is relatively simple. Four spring-laden screws hold the heat sink to the core, two of which have warranty stickers. Four black screws hold the plastic housing to the graphics card PCB. Near the PCI Express slot it says Made in China, just as the label does and the box did, too. Printed next to the core are the U.S. Patent numbers, and FCC and CE labels.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The front of the card shows the VGA, HDMI, and DVI ports. This card is HD/4K ready. Two screws at the top help hold the top cover in place. Two grills provide airflow options through the I/O ports; one is a standard design and the other is the XFX logo. A screw is installed above the HDMI connector to reinforce it. The rear of the card is clean and empty, showing the "Open" design that XFX mentions on the box.

 

 

The side views further show the Open airflow design. The top cover has a gentle curve to it; this combined with the Open nature will aid in airflow when the card is next to another — although it is hard to tell if this is a deliberate design.

 

 

The heat sink is a solid piece of aluminum with three holes for the fan and four for the PCB mounts. The fan is an ARX CeraDyna fan made in China. These fans use a Ceramic sleeve bearing and consume 12V DC 0.20A. The top cover is held in place by the fan base and heat sink "sandwiching" it. The other piece is mounted directly to the PCB.

 

 

With the cooler removed, the XFX R7 250 can be seen in all of its entirety. Four memory ICs comprise the 1GB of GDDR5 clocked at 1150MHz on a 128-bit (dual 64-bit) memory bus. At the center of the graphics card is the 28nm Volcanic Islands - Oland XT GPU core. This core has 384 Stream Processors — a full six Compute Units each having 64 Stream Processors. The core is produced at TSMC in Taiwan. It has a stock clock of 1000MHz with a Boost clock of 1050MHz. The memory is branded SK Hynix — renamed after SK Group acquired a major stake in Hynix stocks. The IC model is H5GQ2H24AFR-T2C and is rated for a clock frequency up to 1.25GHz at 1.5V. Another very similar model (-R0C) is rated at 1.6V for 1.50GHz.
