12ms transfer speed! Apple's Vision Pro headset provides a lag-free view of the world

On July 12, according to Korean media reports, Apple’s head-mounted device Apple Vision Coming soon to the Pro, the device uses a new type of dynamic random access memory (DRAM) to meet its high-performance needs. This DRAM is specifically designed to support Apple's R1 input processing chip.

It is reported that Apple Vision Pro consists of two chips, of which the main processor is the M2 chip, which is responsible for content processing, running the visionOS operating system, executing computer vision algorithms and providing graphics content. The R1 chip is responsible for processing all information from the 12 cameras, 5 sensors and 6 microphones in the head-mounted device and streaming the image to the display in just 12 milliseconds, 8 times faster than a human blinking , bringing the wearer an almost delay-free view of the world.

In order to meet the high-speed needs of the R1 chip, it is reported that Apple Vision Pro will use SK A low-latency DRAM chip from hynix with a capacity of 1 gigabit. This DRAM chip has an increased number of input and output pins designed to minimize latency. In addition, the DRAM chip also uses a unique packaging method called Fan-Out Wafer Level Packaging, by attaching it as a single integrated unit to the R1 chipset, doubles the processing speed.

According to the editor’s understanding, Apple’s head-mounted device Apple Vision is expected to Pro will be officially launched early next year. Initially, Chinese contract manufacturer Luxshare will be responsible for assembling the device. However, it is expected that production in 2024 may be limited to less than 400,000 units due to production problems with the supply of micro-OLED displays and outward-curved lens lenses for the wearer's eyes. This means Apple needs to overcome supply chain issues to meet user demand for this innovative device.

In short, Apple’s upcoming head-mounted device Apple Vision Pro will use new DRAM technology to support its powerful input processing chip and excellent performance. Despite facing some supply constraints, the device is still eye-catching and promises to give users an immersive audio-visual experience. We will continue to pay attention to Apple’s latest developments and look forward to its further breakthroughs in the field of head-mounted devices.
