As shown in the image below, the new device will include Qualcomm’s MDM9635M chip, also known as the ‘9X35′ Gobi modem platform. This new chip promises significant performance improvements over the “9X25″ chip found inside of the current iPhone 6 and iPhone 6 Plus, capable of delivering up to twice the theoretical LTE download speeds.
The Qualcomm chip hit the market last year inside a South Korean variant of the Galaxy S5. It supports speeds of up to 300 Mbps for download, double the 150 Mbps currently supported by the iPhone 6. It has the same 50 Mbps upload limit.
The chip is built using a new 20nm production process and is slightly smaller than the one used in the iPhone 6. Other benefits of the production process include better power efficiency and reduced heat generation.
"The Category 6 speeds enabled by the Gobi 9×35 will allow customers to enjoy blazing-fast downloads, snappier application performance due to lower network response time, and run more connectivity based applications smoothly, as well as concurrently," says Qualcomm. It is "backwards compatible and supports all other major cellular technologies, including DC-HSPA, EVDO Rev. B, CDMA 1x, GSM and TD-SCDMA."
Previously leaked rear shell photos suggest that only the internal design of the iPhone will be modified with the iPhone 6s model.
