I'm actually having doubts its a real H3, the Ambarella's I've seen use a metallic heatspreader. Thinking it might be a custom SoC
Mavic Pro-2 vs Zoom and P4P - Line Skipping + Sensor Heat?

If that’s true it’s mildly entertaining they might ask their chip supplier to put a giant H3 on It. Distinct possibility.
What other devices use the H3? The heat-spreader may be different based on the customers needs, in the PC world desktops have a metal cover since they have a dedicated fan, while laptops do not (or use a much smaller metal cover) because they use a custom cooling system and use one fan for multiple chips.
The m2 seems to use the 2nd approach with a single large metal heatspeader/shroud and a single fan.
We can also look for tear-downs of other devices with the H3...
That's a good point actually. I was doing some computer work yesterday and noticed that two GPUs of the same model were different in appearance.
I think the potential media blowback of that would be far too risky, especially since the chip is something that will almost never be seen without an all-out, warranty-voiding tear down.
Chips are almost always available in multiple interfaces and packages to suit the customer's needs, and Ambarella does have H2 and H22 variants shown online in a standard ceramic package. Heck, the image of the aluminum heat spreader above could even be a rendition, and not an actual processor.
There is something in the M2 called H3, and of it's not Ambarella I think it will look pretty shady on the part of DJI.
I was joking. Its common knowledge semiconductor suppliers offer different package styles- including custom lettering.

Not sure but worth looking. Typically this stuff is hidden under the SDK API and not really relevant to the application designer.
Maybe its a Hambarello H3 ? 
From what I understand its using custom SoC. A DJI rep in RCGroups confirmed that it is not Ambarella.
Pictures are not even affected by this so called video issue people are talking about. I think many are confused about this entire process and are now making it appear worse than it even is.. Just like people think ambarella soc is used, they are 100% wrong.

Make what you will of that.

People could always ask bladestrike or any of the others close to DJI who claim to know what SOC was employed if it’s really important to them.Maybe its a Hambarello H3 ?

Doesn’t look like it will encode 4K or H265. It’s a few years old also.
Interesting....wen to this companies web site. I dont see anything there that makes me believe that they have any real experience in raw image sensor readout, RGGB deBayering, image processing, scaling or noise reduction abilities.....nothing at all.
I hope that if DJI left Ambarella, that they moved to another company with heavy camera image processing experience!
DJI could get burned if they go with a "no name" image processor. Hopefully they weren't sold on a great processor only to find out it wasnt what they thought it would be!
Who knows? This is actually turning out to be a super mystery. We have a possible DJI insider saying its NOT an Ambarella chip, we have Ambarella publically saying "DJI left us!" ...yet we still are seeing photos with "H3" on the mainboard.
WTF??
I think all winner chip illustrates that any company can put "H3" on their chip.
Yep unfortunately thats all I heard about them, the company has been around a while with their PowerVR GPU's used in mobile phones (like iphone until recently). Perhaps if its custom design, DJI worked with them on it? I know the Autel Evo uses the H2 SoC and the same ceramic package that can be found online is also seen in the teardown on the FCC website.

I very much wish it was an Ambarella H3 so at least we could know what its capabilities were, but it doesnt change the fact that we got a 1" CMOS sensor that failed to live up to at least some peoples expectations, be it deliberate for product differentiation or due to technical limitations.
