AMD is set to introduce its next-generation Navi graphics accelerators for Radeon graphics cards soon, which will be aimed at desktop gaming PCs. Despite the fact that the announcement is scheduled for May 27, the first image of the board of the future AMD Radeon RX video card based on the Navi architecture has appeared on the Web. It seems to be a mid-level or even high-end solution, because the PCB indicates the use of a 256-bit bus and GDDR6 memory. Apparently, we are talking about a 7-nm video card, which is designed to become a true successor to the Radeon RX 480.
If you look closely at the details, you can see the prepared BGA (ball grid array) pads for soldering the main GPU chip and video memory. Unfortunately, it is impossible to say for sure which particular crystal we are talking about, but it will probably be a very productive solution. Eight BGAs for memory chips are visible around the GPU footprint. The number of pins per BGA for memory chips is 180, so we are talking about GDDR6. Thus, an accelerator with this PCB will be the first AMD Radeon product to use GDDR6.
8 video memory pins also indicate 256-bit bandwidth. Perhaps the card will be positioned as a competitor to the NVIDIA GeForce RTX 2070, which also has a 256-bit bus and 8 GB of GDDR6 video memory. Only the front side of the printed circuit board has BGA contacts for memory chips, so the accelerator will probably be limited to 8 GB of video memory.
In terms of power, the card supports 8-phase VRM and power is supplied through two PCIe slots. The contacts indicate the possibility of installing two 8-pin connectors, but manufacturers can use them for 6-pin connectors. It is possible that this is a rather early version of the PCB for the future AMD accelerator, which may still change.
It is known that AMD Navi will support ray tracing (one of the key features ). It was also reported that video cards with the Navi architecture will receive support . This technology is analogous to NVIDIA Adaptive Shading and is designed to save graphics card resources. It allows you to reduce the load when calculating peripheral objects and zones by reducing the accuracy of calculations.
The official announcement of 7nm Navi graphics cards and 7nm Ryzen 3000 processors is expected on May 27 at a special presentation of the Computex 2019 event, which will be hosted by AMD CEO Lisa Su.
