Ultra-secure Blackphone will feature 2GHz Tegra 4i processor

Today Silent Circle and Geeksphone revealed their jointly-developed handset will feature an Nvidia Tegra 4i CPU. The companies also fully divulged the rest of the specs.
April 28, 2014

Back in January, Silent Circle and Geeksphone announced a joint-effort to develop the ultra-secure ‘Blackphone’ smartphone. The two companies would call the company SGP Technologies.

What makes the Blackphone special is that it runs a modified version of Android called PrivatOS, alongside a set of special Silent Circle apps that are designed to put security and privacy first. At MWC, SGP gave us a few more details as to what the handset would offer and even began offering the device for pre-order at the price of $629.

As for the handset’s specs? During MWC we learned that the Blackphone would feature a 4.7-inch HD IPS display, 2GB RAM, 16GB storage, an 8MP camera, 5MP front and it would offer LTE and all the other connectivity features you’d expect. What we didn’t know is what processor would power the device, other than it would be a quad-core running at 2GHz or higher.

Tegra isn't exactly a common choice in the mobile world these days, particularly when it comes to smartphones, but SGP remains confident that Nvidia is the right partner for the device.

Today SGP Technologies has finally revealed more details about the CPU, and has also further detailed a few other specs. As it turns out, SGP is turning to Nvidia, who will provide a 2GHz Tegra 4i processor package. Tegra isn’t exactly a common choice in the mobile world these days, particularly when it comes to smartphones, but SGP remains confident that Nvidia is the right partner for the device.

Aside from clarifying what CPU it will run, SGP also reveals that the phone will have a 5MP front shooter, gravity/light/magnetic/proximity sensors, microSD, micr-o-SIM and a 2000 mAh battery. We also have learned that PrivatOS is built on Android 4.4 KitKat.

Overall, the Blackphone has rather solid specs and could be the perfect device for those that feel the ‘typical’ Android experience doesn’t afford them a high enough level of security. On the downside, it seems that the Blackphone won’t feature 2GB RAM after all — opting instead for just 1GB.

Anyone out there interested in picking up the Blackphone when it becomes available? Conversely, do you feel this ultra-high level of security is largely unnecessary?
