The hacked apart cable costs as much as a Roku because it has the same kind of horsepower
The fine software developers over at Panic are working on some new AV software, and they are investigating Apple’s new-ish Lightning Digital AV Adapter. What they found is that unlike the earlier 30-pin module, the Lightning adapter doesn’t carry a native 1080p signal. In fact, when mirroring, Apple says the optimum resolution is 1,600-by-900, and, when that signal is shown on a 1080p display, it is likely up-converted, showing artifacts consistent with streaming and uncompressing video data
What’s more interesting is that they split open the cable and found a full ARM processor with 256MB of RAM to process video signals inside the adapter cable. We knew way back in September that the 8-pin adapter wouldn’t carry video natively, but Apple was able to build a cable. How? Panic thinks that it is actually streaming an AirPlay network signal through the cable, and the ARM processor is decoding it.
Why would Apple do this? It’s likely Apple wants to move people to AirPlay wireless streaming to Apple TV, so this is just a stopgap solution. Rather than making a larger Lightning cable, it sacrificed on wired video-out quality and HDMI (And VGA?) cable costs.
Update: Our friends at Braeburn and an anonymous Apple Engineer sent along their takes on the situation below:

According to industry sources, Apple has not collaborated with Samsung in the process to develop its A6 microprocessor used in its latest iPhone 5. Samsung has handled the manufacturing of the processors used in previous iPhones and believed to have contributed in their design to some degree… It now appears that the structure of the deal has been dramatically adjusted…Apple is still relying on the Korean firm to manufacture its chips but has made it clear it will no longer use its rival’s technology.
We heard conflicting reports in September regarding Apple’s decision to reduce component orders from its biggest supplier, Samsung. Reuters claimed the reduction in orders was an attempt to simply “widen its supply chain,” while others reported Apple is actively reducing orders of displays, memory chips, and batteries specifically due to increasing tension between the companies. According to the report’s source, an unnamed senior Samsung official, Samsung is now only manufacturing the A6 chips on a “foundry basis”:
“There are three kinds of chip clients. Some want us to handle everything from chip design, architecture and manufacturing. Some want us to just design and manufacture. Some want us to just make the chips. Apple is now the third type,’’
Related to today’s report: Apple’s recent hiring of Samsung chip designer Jim Mergard. The report claimed the hiring of Mergard, who was working specifically on ARM chip designs at Samsung and prior, increases the “mutual tension”… expand full story

Former Apple CEO John Sculley recently attended a South Florida Technology Alliance event to discuss Apple and the genesis of tablet computing, specifically: the Newton MessagePad and ARM Processor.
The MessagePad is the first series of ARM 610 RISC processor-based mobile devices developed by Apple for the Newton OS platform in 1993. Since then, it has become the dominant platform for mobile computing.
“Handwriting was never intended to be a very important aspect of it. […] It was really much more about the fact that you could hold this thing in your hand and it would do a lot of the graphics that you would see on the Macintosh,” explained Sculley at SFTA.
The tablet-like digital assistant spurred a flurry of models with various ARM processor. The series is generally remembered as a market flop now, of course, but Apple’s ARM initiative essentially paved the way for greatness. As The Next Web first noted, the iPhone today uses a by-product of the Newton MessagePad’s specifically designed ARM core.
“No microprocessor existed that would allow you to do mobile graphics-based software,” Sculley revealed, while discussing the birth of ARM.
