GIGABYTE HD7850 OC 'WindForce x2' Review

Closer Look


Heatsink Assembly

The GPU cooler is made up of a black translucent plastic shroud with twin 100mm fans. These sit atop of an aluminium finned heatsink with twin copper heatpipes which as you can see make direct contact with the GPU core. Our sample had a perfect contact surface and so if retail examples are replicated, there should be no requirement to replace the thermal interface material.


HD7850 OC Naked

The familiar GIGABYTE blue PCB is designed so the VRM module sits close to the I/O backplate vent. The core as you would expect is slightly off centre and framed by 8x256 GDDR5 modules which aside of the VRM placement is typical of today's GPU designs.


Voltage Regulation

The VRM is a 4 phase design and makes use of GIGABYTE's Ultra Durable 2 combination of Solid State Capacitors, Ferrite Core chokes and low RDS(on) MOSFETs.


HYNIX GDDR5

The GIGABYTE HD7850 OC features an identical configuration of 2GB GDDR5 found on the HD7870 which is made up of 8x256MB modules. The memory chips come courtesy of HYNIX and are labelled as H5GQ2H24MFA T2C. These chips are rated to run at 1250MHz (5GB/s effective) so we expect some good overclocking results on the memory.


Pitcairn Core

Finally we arrive at the Pitcairn core. Like the whole 7000 family of processors, the Pitcairn is fully exposed with no IHS present to protect the delicate silicon. Although it has for GCU's disabled, we still hope to see some good levels of performance being churned out.
