Mar 6, 2024 · Broadcom Vantage 5 And Vantage 6 PCIe CXL Gen5 And Gen6 Retimer Features. Broadcom is building Vantage 5 and Vantage 6 on 5nm. That means Broadcom’s controllers will use a few watts less per chip than its competition.

Oct 25, 2023 · - CXL allows augmenting system memory footprint at lower cost by running over existing PCIe links to add memory outside of the CPU package. - Intel Xeon roadmap fully supports CXL starting with 5th Gen Xeons, and Intel CPUs offer unique hardware-based tiering modes between native DRAM and CXL memory without depending on the operating system.

Jan 29, 2025 · CXL is an emerging high-bandwidth, low-latency interconnect that enables efficient memory sharing between CPUs, GPUs, and accelerators. Broadcom’s Atlas switches seamlessly integrate CXL to: Optimize memory pooling and workload distribution. Improve performance in cloud-based applications.

When the Broadcom switch and retimer are deployed together, this next-gen solution allows data center architects to connect 40% more slots, build systems with larger fanout and reliable signal integrity.

Mar 6, 2024 · Broadcom told us that it plans to start sampling its 144 lane PCIe Gen6 switches in the second half of this year for 2025 use in servers. Those large switches will provide more connectivity for accelerators to have direct device-to-device communication. Broadcom also told us that it will support CXL in its family.

Broadcom offers a broad portfolio of industry leading PCIe Switches and Retimers that are high performance, low latency, low power, and multi-purpose.

Broadcom switches, such as PEX89000, support multi-host connectivity and also allow dynamic removal, addition, and allocation of the I/O devices from one host to the other. The PEX89000 switches incorporate advanced security features such as attestation and hardware secure boot.
