Infrared photographer shares BE-S1000 from Baikal Electronics, 48 Core Arm Cortex-A75 CPU for HPC
Baikal Electronics is the most famous processor design company in Russia, using Arm or MIPS architecture to design, called the Baikal series. Last year, Baikal Electronics received the self-developed Baikal-M from TSMC and lit up the new 48-core Baikal-S code-named “BE-S1000”.
Renowned infrared photographer Fritzchens Fritz managed to get hold of Baikal-S and show its interior through an infrared microscope. Baikal-S is based on Arm architecture, with 48 Cortex-A75 cores placed in 12 clusters, each cluster has 4 cores, each core has 512KB of L2 cache, each cluster shares 2MB of L3 cache, plus 32MB of L4 cache. It has a base clock of 2.0 GHz, a boost clock of 2.5 GHz, a TDP of 120W, and can run in single-, dual-, and quad-socket systems.

Baikal-S is manufactured using a 16nm process, with a chip area of about 607mm². It is packaged in a F_C_LGA-3467 package. The package also contains a RISC-V architecture co-slave processor for secure boot and management. In addition, Baikal-S supports six-channel DDR4-3200 memory and ECC, with a maximum capacity of 768GB, provides five PCIe 4.0 x16 slots, two 1GbE interfaces, and various general-purpose I/O interfaces.
According to the official SPEC2006 CPU Integer, Coremark, Whetstone, 7Zip and HPLinkpack, and other benchmark test data, the overall performance is comparable to the Xeon Gold 6148 (20 cores/2.4 GHz) of Intel Skylake architecture, or the EPYC 7351 (16 cores/2.9 GHz) of AMD Zen architecture.
