Leaked images that are claimed to be of the printed circuit board (PCB) on a Navi-based graphics card show eight DRAM memory packages surrounding the GPU. A closer examination reveals a ball grid array (BGA) with a 180 package size.
From that, we can deduce that Navi is running with GDDR6 memory. One of the reasons why that is interesting is because AMD has been turning to HBM and HBM2 memory for its Vega-based graphics cards. While we will have to wait and see how pricing shakes out, if the leaked PCB shots are legitimate, the use of GDDR6 could mean cheaper prices and wider availability, compared to AMD's Vega lineup.
There are a few other details we can discern. They include:
- 8-phase VRM
- Two PCIe power connectors (unknown if they will be 6-pin or 8-pin)
- 2x DisplayPort
- 1x HDMI
Over on YouTube, there is a detailed examination of the leaked PCB, which is worth checking out if you have around 17 minutes to spare. Here it is...
If the analysis is correct, this particular Navi card will be around 250W to 300W. How does that compare to current generation cards? Here's a breakdown:
- Radeon VII: 300W
- Radeon RX Vega 64: 295W
- Radeon RX Vega 56: 210W
- GeForce RTX 2080 Ti: 250W (260W for Founders Edition)
- GeForce RTX 2080: 215W (225W for Founders Edition)
- GeForce RTX 2070: 175W (185W for Founders Edition)
- GeForce RTX 2060: 160W
