Baikal BE-S1000: Russian-made 48-core CPU appears in benchmark results and in photos

Baikal Electronics has revealed some details about the BE-S1000, an ARM-based processor intended for servers. As the image below shows, Baikal claims that the BE-S1000 should match the performance of a Xeon Gold 6148, a 20-core processor that Intel released in 2017. Additionally, the BE-S1000 is alleged to fare well against the AMD Epyc 7351, a 16-core part, and should offer 85% of the performance of the Kunpeng 920, Huawei's 48-core processor.

Separately, Fritzchens Fritz was able to source a BE-S1000 and shared photos of the processor on Twitter. Seemingly, the processor has twelve CPU clusters, each with four ARM Cortex-A75 cores and 2 MB of L2 cache. Moreover, Baikal Electronics has included 32 MB of L4 cache, which are situated in the four large areas at the processor's centre. Furthermore, the BE-S1000 has six 72-bit memory controllers that support up to 768 GB of DDR4-3200 RAM.

Fritz adds that the BE-S1000 has five PCIe 4.0 x16 interfaces too, as well as two Gigabit Ethernet interfaces and an integrated USB 2.0 controller. Allegedly, the processor consumes approximately 120 W and is built on 16 nm TSMC nodes. Incidentally, the BE-S1000 has a 607 mm² die size, making it almost the same size as the AD102 in NVIDIA's GeForce RTX 4090. Initially, Baikal hoped to release the BE-S1000 in 2023. However, sanctions resulting from Russia's invasion of Ukraine have suspended mass production indefinitely.
