AMD is soon going to announce their next-generation Navi GPUs for Radeon graphics card which will be aiming desktop gaming PCs. While the announcement is scheduled for 27th May, a printed circuit board shot of what seems to be the next-gen AMD Radeon RX Navi based graphics card has leaked out.
AMD Navi GPU Based Graphics Card PCB Leaks Out – Designed For Radeon Cards, Features GDDR6 VRAM Along a 256-bit Bus
The alleged PCB seems to be of a high-end graphics card based on the 7nm Navi GPU. It’s certainly not a entry level graphics card based on the specs we are looking at and could be a proper Radeon RX 580.
So coming to the details, we see the large ball grid array for the GPU and VRAM. We can’t say for sure which GPU or which Navi variant this card would utilize but it would probably be a high-end design. Around the GPU package, we can spot BGA’s for 8 DRAM packages. Looking closely, the BGA package size is 180 which means this card will be using GDDR6 memory making them the first AMD based card to utilize the new standard.
The 8 DRAM packages also confirm a 256-bit interface for the bus which shows that this card would be placed somewhere around the RTX 2070 which also features a 256-bit bus interface and 8 GB of GDDR6 VRAM. Only the front side of the PCB has the BGA packages which suggest the card would feature 8 GB of VRAM since the backside of the PCB cannot be utilized for extra DRAM placement.
In terms of power delivery, the card rocks an 8 phase VRM and power is provided through two PCIe connectors. The cutouts are for 8-pin connectors but it’s up to the manufacturers to use them as 8 or 6 pin power outlets. More on the power delivery system of this PCB is detailed by Buildzoid in his video which can be seen below:
