Introduction
AMD's approach to new generations of graphics processors has been different for the past two generations. The Radeon R9 200 series initially saw the introduction of just one silicon, codenamed "Hawaii," which drove the company's previous flagship R9 290 series, while the rest of the lineup saw a cascading re-badging from the previous generation. AMD's previous generation flagship, the HD 7900 series, went on to become the performance-segment R9 280 series, and so on, and the performance-segment "Tonga" silicon was added afterward. The story is predictable even today.
With this generation, there is essentially one new silicon, the HBM-equipped "Fiji," which has been launched this week and will eventually drive up to five products from AMD. The previous-generation flagship silicon "Hawaii" now drives AMD's performance-segment products, the Radeon R9 390X and R9 390 Non-X we're reviewing today.
The Radeon R9 390 is based on the "Hawaii" silicon (now referred to as "Grenada" without any silicon changes) and features the same core-configuration as the R9 290. The standard memory amount has been doubled to 8 GB across the board and clock speeds see an increase from 950 MHz to 1000 MHz on the core and from 5.00 Gbps to 6.00 Gbps on the memory.
The PowerColor R9 390 PCS+ comes with a small core overclock of 10 MHz out of the box; its memory clock remains unchanged. As a cooling solution, a mighty triple slot, triple-fan cooler is used. Price-wise, the card is retailing with a slight $10 increase over the reference design.

The Card
PowerColor is introducing a new cooler with the R9 390 series. It uses a triple-slot design with three fans. All surfaces are made from metal, which definitely adds to the product's high-quality feel. On the back, you find a baseplate. Dimensions of the card are 29.0 cm x 11.5 cm.
Installation requires three slots in your system.
Display connectivity options include two DVI ports, one HDMI port, and one DisplayPort.
The GPU also includes an HDMI sound device. It is HDMI 1.4a compatible, which includes HD audio and Blu-ray 3D movies support.
A physical CrossFire connector is not present as all Hawaii-based GPUs send their CrossFire data via the PCI-Express bus.
