AMD "Navi" Graphics Card PCB Pictured, uses GDDR6
Pictures of an upcoming AMD Radeon "Navi" graphics card bare PCB made it to the web over the weekend. The picture reveals a fairly long (over 25 cm) board with AMD markings, and a layout that doesn't match with any reference-design PCB AMD launched so far. At the heart of the PCB is a large ASIC pad that appears to be within 5 percent of the size of a "Polaris10" chip. The ASIC is surrounded by eight GDDR6 memory pads. We could guess they're GDDR6 looking at the rectangularity of their pin-layout compared to GDDR5.
The PCB has provision for up to two 8-pin PCIe power inputs, and an 8+1 phase VRM that uses premium components such as rectangular tantalum capacitors, DrMOS, and a high-end VRM controller chip. There's also provision for dual-BIOS. The display I/O completely does away with DVI provisioning, and only includes the likes of DisplayPort, HDMI, and even USB-C based outputs such as VirtualLink. The fan header looks complex, probably offering individual fan-speed control for the card's multi-fan cooling solution that could resemble that of the Radeon VII. Looking purely at the feature-set on offer, and the fact that "Navi" will be more advanced than "Vega 2.0," we expect this card to be fairly powerful, going after the likes of NVIDIA's RTX 2070 and RTX 2060. AMD is expected to unveil this card at the 2019 Computex, this June.

it really does not matter that much but I was kinda hoping it would be near all HBM for AMD at this point, like a RX680 carrying the HBM 1.0 that was used in the Fury X and probably has gone down in price etc by now.
AMD is probably pushing the clocks too much, or it could be that the shader count is fairly big or a combination of both.
Navi is the polaris replacement,
It needs to be 75% faster than polaris to beat the 2070.
RX 480 was 40~% faster than the 380X and I expect the same here, 40 percent improvement over the fastest polaris based offering.
Navi is just another fancy name for Polaris at this point, I have this feeling it won't be much different from it: a cost effective mid range/lower high end chip. Maybe some RT-related tweaks. Some minor architectural improvements, and mostly just riding on 7nm to keep it in the game. Your bandwidth/VRAM analysis I think is spot on.
It's likely an engineering example with all those dip switches.
Doesn't power consumption of about 200W warrant 2 connectors?
I'm glad to see gddr6 used on midrange down from AMD. Save hbm for the high end.
@buildzoid was speculating on it
Navi this year, with luck will probably target RTX 2060, I don’t expect nothing more.
If navi rx 680 is at least 60% faster than the rx 580 then i'm happy.
They need almost Radeon VII performance at half of its power consumption.
It's rumored that PS5 will launch next year, so the GPU should be almost ready by now...
If this beats the current price point card it replaces by 50% they would be daft to sell it at that price point....
