ARM Unveil New VR-Ready Processors

ARM Unveil New VR-Ready Processors

As each core can have different performance and power characteristics - and the Cortex-A processors also contain dedicated processor instructions for machine learning and AI tasks - ARM says it is possible for AI performance to increase by over 50 times during the next three to five years.

Cortex-A75 brings a brand-new architecture that continues the rapid upward trend in processor performance while retaining the critical power efficiency achieved by its highly successful predecessor.

Apart from the bump in performance which can be considered an evolutionary development over the existing chips, ARM is also hyping its new chips conform to DynamIQ big.LITTLE technology. So with the Dynamiq technology, the developers can now customise a single cluster into pairs of 4 plus 4, 1 plus 7, 2 plus 6, 1 plus 3 and many more variations.

Trump criticizes German trade surplus, again
Trump's reference to Germany's large trade surplus with the United States draws attention to a contentious issue at the summit. He is likely to be received warily, but the White House says the president has made personal breakthroughs with his peers.

"I have been at ARM for over a dozen years and can't remember being this excited about a product delivering such a boost to single threaded performance without compromising our efficiency leadership", said Nayampally. Designed for laptops and large-screen mobile devices, ARM says the ML and VR-ready processor is also suitable for autonomous vehicle use, and in particular when speedy responses are required.

ARM has announced the Cortex A75 for flagship level devices, while the Cortex A55 comes out for mid ranged smartphones. This brand new GPU is tailor-made for the high fidelity mobile gaming and mobile VR.

In related news, a leak out of China suggests the Snapdragon 845 will be powered by the Cortex-A75 cores. This technology allows for greater flexibility of cores, allowing companies like Qualcomm to mix and match up to eight cores in a single cluster enabling them to tweak performance, design, and energy, and overall more customisation. The firm claims "over 20% more integer core performance" and "substantial enhancements in floating point and memory workloads performance".

British Airways disruption continues for third day after IT system crash
While other airlines have been hit by computer problems, the scale and length of BA's troubles were unusual. In a statement, BA said its IT systems were moving " closer to full operational capacity".

The Cortex-A55 offers up to twice the performance of the Cortex-A53 at up to 15 percent improved power efficiency this time benchmarked for a 16nm manufacturing process. This overhaul represents a major change from the A-73 and A-53, and has some interesting implications for the company's architecture and Built on ARM Cortex Technology licensees, but we'll touch more on that in our deep dive.

The Cortex-A75 makes double-figure performance improvements across the board, with ARM claiming it's on average 22 percent better than the A73, with 16 percent higher memory throughput, and a 34 percent improvement in its Geekbench score. But, as it is in the list of ARM's new processors, the company says that it is nearly 2.5 times more power efficient than the A53 one. With these new chips inside the chip, mobile devices will be able to perform machine-learning tasks without having to rely on a cloud far away and without having to rely on the quality of external bandwidth.

All the new CPU designs are expected to hit devices in the first quarter of 2018.
