As for Arm's new CPU designs, two of the three cores don't support 32-bit code. In August 2021, the Play Store will stop serving 32-bit apps to phones and tablets. Since August 2019, Google has required all app developers to ship 64-bit versions of apps on Google Play alongside 32-bit versions. Google is doing its part on the Android side of things. ARM says this small core is within striking distance of the Cortex A73, the "big" CPU core in 2017 flagship smartphones. All three CPU designs use the new Armv9 architecture, which includes several security enhancements like the containerized "confidential compute architecture."Īrm's new CPUs continue the march toward the death of 32-bit. 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.įurther Reading Containerize all the things! Arm v9 takes security seriouslyWhile the Cortex X1 and A710 are both based on the previous designs that go back to 2018 Cortex A76 cores, the smaller Cortex A510 is an entirely new design. 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. Devices will finally be rid of the smaller Cortex A55 cores that were introduced in 2017.
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. 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.Īrm CPU designs include cores in three sizes: "little," "big," and "performance," all of which tackle different workloads at various power-consumption levels. 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. Arm has announced its next-generation CPU designs, which will probably hit the market in early 2022.
