The Qualcomm Snapdragon 820 processor was announced yesterday and it looks pretty impressive. In addition to being considerably faster, the GPU is about 40% faster than the Snapdragon 810. Also, LTE has received a big boost as it now supports speeds of up to 600Mbps and 802.11ad WiFi. It is much more efficient and uses machine learning to fight mobile viruses and malware. It looks impressive for a quad-core CPU.
Naturally, Qualcomm's new flagship chip is significantly faster than its old one. But perhaps more useful is its power efficiency - the company claims it's around twice as efficient as the 810, and it consumes around 30 percent less energy overall. Without any major breakthroughs when it comes to battery technology, the best way to increase battery life is by making chips more efficient.
