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.

If this makes it possible to sell it around $220-230 as was rumoured, than it is a rational decision.
londisteThis would be right around, if a little below, Vega64, GTX1080 and RTX2060.
If you get the ~GTX 1080 power for that rumoured $220-230, I really welcome it.

I expect that Navi will be able to use either GDDR6 or HBM. That opens up a lot of variants at different performance / price-points.

Interested but red flags about heat and power consumption abound with a large card and 2 8-pin connectors. Maybe it won't be that bad, but having been through the literal space heaters that the R370/80 gen was I will need to see the full release product reviews. Those AMD cards a couple years back would pull 350w+ and had to have it's 2 fans on loud blow dryer mode anytime you were gaming. I had to actually put a window ac unit in a room with the pc running a R370 one summer, in a house with central air. AMD has been better on that front with more recent cards, but I'm leery enough to wait for some detailed reviews on any AMD card with a big power draw.

I see that as what they need to target, and not 1080p... but at 1440p. I think they can and it's not all that of a reach even holding to the major bit of GNC architecture, especially if they strip-out everything non-essential gaming. Then going with 7nm and GDDR6, I'm not expecting some 160W TDP like a RTX 2060, although might say 170W TDP is more the ballpark. Get in the market a for $280, and AMD can sell all they can get.

too many people getting their panties in a bunch over a mock up slash presentation board. It is not a production or a reference board. Consider this a PR stunt this year.

notbBut what about the PS5 targets? 4K@60fps? PC-like IQ?
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...
For console optimisation they surely don't need that level of raw gpu power. More like a Vega64 will be enough for this performance needs.

Console Optimization in GPU front is nothing more than cutting each and every corner to achieve the target framerate.
Just like the current enhanced consoles most devs will use Dynamic Resolution Scaling, cut your resolution in half in demanding scenes and call it 4K.
There's not a single AAA game running at real, fixed 4K on PS4 Pro but I see them still marketing it as a 4K gaming console.

Yeah, it's more about optimizing the content rather than more efficient rendering. Render resolution is one thing, but also calibrating LoD and the assets(meshes, textures) themselves for the target hardware. Console games might be more calibrated for the target hardware than PC games, simply because they have one or a few possible hardware configurations, but it's a myth that they are more efficient or perform better than comparable hardware.

(rumor) beating expectations
Without baseline known expectations that is useless.
There are as many wishes as rumors at this point... Yes, I would like to order a rtx 2080 performing radeon for about half the cost and the same power usage, hold the fries.

Also, Charlie's sources said it had a major defect that required a retape, hence delay from CES to Computex.
Technically a retape is a 3mo. min delay... so... who knows when. I prefer to just wait and see than get hyped and disappointed.

Frankly far more interested in the Rome launch than Navi.

It is not sure if this is Navi and most importantly it is an experimental development board and therefore it has a two 8 pin PCIE connector. So it says nothing at all.
