Arm today announced a suite of new processing core intellectual property intended for the chips that will power high-end phones starting in 2021. The new designs are for the new, cutting-edge 5nm manufacturing process that is just becoming available for the most high-end chips. (Currently, the main chips for flagship phones are made with a 7nm process.) The new Cortex-A78 offers 20% more sustained general computing performance compared to the A77. The new Mali-G78 offers 25% better graphics performance compared to the G77. Up to 24 Mali-G78 cores can be used in a single chip design. The new Ethos-N78 machine learning core offers 25% better performance efficiency compared to the N77. The N78 can be configured in over 90 different ways, offering anywhere from 1 TOP/s to 10 TOP/s. Companies that design processor chips often license Arm designs and use them as a starting point for their own chips, customizing the Arm designs along the way. Arm is extending its collaboration with such companies in a program called Cortex-X Custom, to produce even higher-end CPU designs. The first result of this program is the Cortex-X1, developed with an unnamed partner. The Cortex-X1 will have a 30% peak performance increase over the Cortex-A77. Arm is also announcing the Mali-G68, a "sub-premium" GPU core that brings many of the modern features of the new Mali-G78 to "sub-flagship" phones; it supports up to six GPU cores in one chip.
