Performance Summary
Raspberry Pi's 400 runs on the Broadcom BCM2711, an ARM chip with 4 cores, and ships here with 4GB of RAM. Our benchmarks put its Geekbench 6 result at 742 multi-core and 300 single-core, with 7-Zip compression reaching 6,020 MIPS. It also delivered 15.39 GFLOPS in our Linpack run. It sips 3.0W when idle, rising to 5.9W under full load.
