Speeds and feeds for the three new CPU designs. [credit: Arm ]
Arm has announced its next-generation CPU designs, which will probably hit the market in early 2022. With all-new cores, a new architecture, and the death of 32 bit, the new designs are proving to be among Arm's biggest releases in some time. It looks like ARM has not published a post with this information, but you can't ask for a better source than the pages of info at Anandtech.
Arm CPU designs include cores in three sizes: "little," "big," and "performance," all of which tackle different workloads at various power-consumption levels. The follow-up to this year's "performance" X1 core is the Cortex X2, the big core is the Cortex A710, and for the first time in four years, ARM is introducing a new "little" core for high-efficiency workloads, the Cortex A510. Devices will finally be rid of the smaller Cortex A55 cores that were introduced in 2017.
Naturally, everything is faster. ARM is promising a 16 percent faster X2 core compared to current-generation X1-based chips, a 10 percent faster and 30 percent more efficient "big" core, and a 35 percent faster and 20 percent more efficient "little" core. Every core design is also seeing a 2-3x improvement in machine-learning performance, for whatever that's worth. Put all those digits together and ARM says a CPU cluster with the typical phone layout (one Cortex X2, three A710s, and four A510s) should have 30 percent better peak performance and 30 percent better-sustained efficacy.
