A Closer Look

Graphics Card Cooler Front

AMD's cooling solution is a little technology marvel. It is made by Cooler Master and integrates waterblock, pump, and VRM cooling circuitry in one piece.

Graphics Card Cooler Back

The next piece that goes off is the metal backplate, which helps protect the card against damage during handling, while adding to the product's visuals.

After removing the Radeon shroud (which is lit, by the way), we get to take a closer look at the watercooling components.

Note the piece of copper tubing that runs along the right side of the GPU. It cools the voltage regulation circuitry below it, an elegant solution. Other designs use a fan for that, which would add extra noise.

With the waterblock removed, we can finally get a first glimpse of the GPU, which is still covered by A LOT of thermal paste. The waterblock uses a copper baseplate with a milled-out section for the GPU; there is no additional milling for the HBM chips.

The radiator is your typical 120 mm variant, with a very quiet fan made by Nidec.

A row of LEDs will indicate the GPU's power draw, acting as the GPU's activity indicator. The left-most LED is green and will light up when the card is running in ZeroCore power mode (the pump and fan will not turn off in ZeroCore). You may change the color using the DIP switches to the left.

Like on most recent AMD Radeon products, a dual-BIOS switch is included, which serves as a fail-safe in case a BIOS flash goes wrong. The two BIOSes are identical.

Graphics Card Power Plugs

Power delivery requires two 8-pin PCI-Express power connectors. This configuration is specified for up to 375 W power draw.

We've seen the IR 3567 voltage controller on the R9 390x/290X before. It supports software voltage control and monitoring via I2C and is well supported in overclocking software.

Graphics Card Memory Chips

The HBM memory chips are by Hynix. They are specified to run at 500 MHz. The two stacks pictured in the photo are each comprised of five stacked silicon dies, four DRAM and one controller. A total of four stacks are installed, sitting on the silicon interposer (the colorful parts), together with the large GPU die.

Graphics Chip GPU

AMD's Fiji graphics processor uses the GCN shader architecture. It is produced on a 28 nm process at TSMC, Taiwan, with 8.9 billion transistors on a 596 mm² die.
