ARM today kicked off Computex 2016 by announcing its new Cortex Core and Mali GPU, the Cortex A73 and Mali-G71 GPU that are aimed at high-end smartphones and support mobile VR. The new Cortex core from the company is the successor to its A72 core that is up to 30 percent more efficient than any of the company’s previous ARM cores.

The new core is also able to offer 1.3x times the peak performance of the A72, and most importantly for VR, it offers double the sustained performance in its power limit than its predecessor. The core will be manufactured on the 10nm FinFET process, which should allow for significant power savings.

The new Mali-G71 GPU from the company is based on its third-generation architecture, Bifrost. The company claims that it is up to 50 percent faster whilst being 20 percent more efficient. The GPU can be scaled up to 32 shader cores at which point it can rival the likes of Nvidia’s mobile GPUs like the GTX 940M. To better support mobile VR, the GPU features support for 4K resolution, 120Hz refresh rate, and a 4ms graphics pipeline latency.

“VR is one of the most important technological breakthroughs for the gaming industry in a generation,” said Niklas Smedberg, technical director, platform partnerships, Epic Games. “The ability to deliver a compelling VR experience on all platforms, but especially mobile, is critical for the industry’s continued growth and advancement. To enable a great mobile VR experience, devices need to be the highest performing and most energy efficient available.”

ARM says that its new CPU and GPU will enter into mass production later this year, and will start showing in mobile devices from next year. The company notes that 10 partners, including MediaTek and HiSilicon, have licensed the Cortex A-73 core from it, while Samsung and Qualcomm have licensed the architecture. The Mali G71 GPU has also been licensed by HiSilicon, MediaTek, and Samsung.
