Leaked iPhone 18 Pro motherboard hints at Apple’s next cooling upgrade

A new motherboard image claims Apple is redesigning the A20 Pro's packaging for better thermal performance.

A fresh iPhone 18 Pro leak is making the rounds online, and it comes with some pretty bold claims. According to leaker Reptalicant, the alleged motherboard for Apple’s upcoming flagship reveals a redesigned A20 Pro chip package with improved cooling, a beefier Neural Engine, and faster memory. That’s a lot to unpack, especially considering motherboard-level Apple leaks like this are exceptionally rare.

The leak claims better thermals, faster memory, and a stronger NPU

According to the post, Apple is said to be moving the DRAM to the side of the A20 Pro package using WMCM (Wafer-Level Multi-Chip Module) packaging instead of the current layout. The idea is that separating the memory from the main die could improve heat dissipation, potentially allowing the chip to sustain higher performance for longer under heavy workloads.

A20 Pro chip now adopt WMCM packaging, which move the DRAM to the side of the package, allowing for better thermal dissipation. It also get LP6 96-bit memory

The leak also claims the A20 Pro will retain a die size similar to the A19 Pro while adopting LPDDR5X 96-bit memory and a larger Neural Engine for on-device AI tasks. If accurate, it would suggest Apple is focusing less on making the chip physically bigger and more on improving efficiency, thermals, and AI performance through packaging changes.

Interesting? Yes. Convincing? Not quite yet.

The funny thing is that leaks like this almost never happen with Apple. While supply chain reports about specifications are fairly common, detailed motherboard layouts and chip packaging information rarely surface this far ahead of launch, making this rumor particularly difficult to verify.

That’s not to say it’s impossible. Apple has been steadily investing in better thermal management as its chips become more powerful, and improved packaging would be a logical next step. Better thermals would be a welcome upgrade, especially as on-device AI workloads continue to grow. But with no corroboration from Apple’s supply chain or other reliable leakers yet, this remains firmly in rumor territory.

The $1,500 flagship might be closer than you think
Flip phones already broke the $1,500 mark this year, and slab flagships aren't far behind.
iPhone 17 Pro and Google Pixel 10 Pro.

In July, a Google executive broke the silence on the ongoing memory crisis, highlighting a more than fourfold increase in RAM prices between 2025 and 2026, and I haven't stopped thinking about it since. The prices have gone up from $2.80 in 2025 to roughly $12 in 2026, as mentioned in the same report. Run the math for a 16GB memory package, and the cost to the company has apparently gone up from $45 to $192.

That's not a rounding error; it's the floor moving under the entire industry's feet. Google is not alone in speaking about the ongoing memory crisis. We've also seen Nothing's CEO speak about it, and other brands like Motorola, OnePlus, and Xiaomi make price adjustments across their lineup.

I’ve used the Pixel 10 Pro a year. I hope Google fixes these nagging issues on the Pixel 11 Pro
Electronics, Mobile Phone, Phone

I’ve been using the Google Pixel 10 Pro for almost a year now, which means I’ve had plenty of time to figure out what I love about it and, more importantly, what still gets on my nerves. And with the Pixel 11 Pro launching on August 12, just three days from now, my wishlist for Google has gotten pretty long. There’s a lot the Pixel already gets right. The software is still one of my favorite Android experiences, performance is generally solid, and Google’s Gemini features have become genuinely useful in ways I didn’t expect. Those are all big reasons I’ve stuck with Pixel phones for as long as I have.

But spend enough time with any phone and the little annoyances stop feeling so little. Over the past year, I’ve run into a handful of recurring Pixel problems that I really don’t want to carry over to another generation. Some have frustrated me for months, while others have made me question whether I can completely rely on my Pixel when I need it most. So, with the Pixel 11 Pro almost here, I have a few things I desperately want Google to get right this time.

Apple is testing Chinese DRAM even after CXMT refused to cut prices
Apple may be testing CXMT memory for iPhones and MacBooks
iPhone 17 Pro Max

Apple’s search for more memory supply has taken another step forward. The company is now testing DRAM from Chinese manufacturer CXMT across several products, including iPhones and MacBooks, according to The Wall Street Journal. Apple has also held early talks with CXMT about supplying memory for some devices sold in China and is seeking support from the US government before moving ahead.

The timing is particularly interesting. Just recently, we learned that a shortage of DRAM could already be holding up production of the A20 Pro chip expected inside the iPhone 18 Pro. TSMC is said to have around $1 billion worth of finished chips waiting for memory before packaging can continue.
