ARM shows off new chips
British mobile chip designer ARM has been showing off a few new chips at Computex Taipei 2016.
The Cortex-A73 CPU and Mali-G71 GPU are designed to increase performance and power efficiency and support mobile VR.
Mali GPUs are big in the mobile world, with over 750 million shipped in 2015. The new Mali-G71 is based around the company’s third-generation Bifrost architecture.
The core allows for 50 percent higher graphics performance, 20 percent better power efficiency, and 40 percent more performance per square mm over ARM’s previous Mali GPU. It has 32 shader cores, ARM says the Mali-G71 can match discrete laptop GPUs like Nvidia’s GTX 940M.
ARM said that the chip was designed to fix specific problems thrown up by VR, supporting features like 4K resolution, a 120Hz refresh rate, and 4ms graphics pipeline latency.
ARM also showed off itsnew Cortex-A73 core, which prioritizes power efficiency. It’s up to 30 percent more efficient than the previous Cortex-A72 while offering about 1.3 times the level of peak performance, but ARM has also focused on sustained usage — the A73 offers over twice the performance within its power budget.
ARM expects chips to move into production at the end of the year and appear in shipping devices in early 2017.
