Blackphone (model BP1), the new smartphone that offers users encryption services for top notch mobile privacy and security will also feature premium mobile performance. Set to power the ultra secure device is none other than the NVIDIA Tegra 4i mobile processor.

Behind Blackphone is Swiss company, SGP Technologies SA, a joint venture between Silent Circle and Geeksphone. SGP made the announcement detailing Blackphone’s specs on Monday (April 28), along with its reason for choosing the NVIDIA Tegra 4i SoC.

The Tegra 4i processor features 60 custom NVIDIA GPU cores and a quad-core CPU based on ARM technology’s Cortex A9 r4 CPU. With power efficiency in mind, a fifth battery saver core is included in the Tegra 4i’s structure. It also boasts NVIDIA’s own i500 LTE modem and promises high performance and power. "Tegra 4i phones will provide amazing computing power, world-class phone capabilities, and exceptionally long battery life," senior vice president of the Mobile business at NVIDIA, Phil Carmack said in a statement.

SGP specifically chose the Tegra 4i to offer Blackphone users an enjoyable mobile experience to complement its unprecedented privacy features. Potential owners of the device include executives, public figures, tech specialists and individuals who want control of their privacy. NVIDIA’s Tegra 4i will power all the major functions of the Blackphone and users can expect superior and secure web browsing, multimedia, and networking privacy.

Along with its 2.0 GHz quad-core NVIDIA Tegra 4i processor, the Blackphone sports competitive specs. The secure privacy phone features a 4.7-inch IPS HD display with a resolution of 1280 x 720, 16GB of internal storage, 1GB of RAM and a microSD slot.

Blackphone features an 8MP Auto-focus main rear camera and like the recently released HTC One M8, there’s a 5MP front-facing camera on board. Other features include a single micro-SIM slot, Bluetooth 4.0 LE and Wi-Fi 802.11 b/g/n. The phone supports GSM, HSPA+/WCDMA and LTE FDD bands and runs on a 2,000 mAH battery. Blackphone's custom PrivatOS software platform is based on Android 4.4 KitKat.

Privacy features include award-winning encrypted voice, video calls and text messaging with attachments from Silent Circle. Blackphone lets users browse the Web anonymously and protect their mobile VPN, thanks to Disconnect. SpiderOak allows for private and encrypted cloud storage.

"With Blackphone we have engineered a high-end smartphone rivaling the top devices on the market in terms of performance and user experience – and with comprehensive embedded privacy features as a crucial differentiator,” CEO of SGP Technologies SA,Toby Weir-Jones, said in a press release Monday.

Customers who would like to buy a Blackphone secure smartphone won’t have to wait much longer. The handset will be sold unlocked and lands on the mobile retail market this summer. Slated for a release date in the EU and Americas in June, the ultra secure Blackphone comes with a price tag of $629. During its pre-sale run in February at Mobile World Congress, the device sold-out quickly, indicating that mobile privacy is a concern among today’s consumers.
