Amd Joins Intel-Powered CXL Interconnection Consortium

Compute Express Link (CXL) is an industry-standard open interconnect that offers high-bandwidth, low-latency connectivity between host processors, systems, and devices such as accelerator cards, memory buffers, and smart I / O devices. Intel boosted CXL a while back based on PCIe 5.0, and now AMD is joining this initiative.

AMD Joins CXL Initiative, Which Will Use PCIe 5.0 Interface

Compute Express Link (CXL) is an industry-standard open interconnect that offers high-bandwidth, low-latency connectivity between host processors, systems, and devices such as accelerator cards, memory buffers, and smart I / O devices. Intel boosted CXL a while back based on PCIe 5.0, and now AMD is joining this initiative.

Designed to meet the increasing demands of high-performance computing workloads, CXL targets heterogeneous memory and processing systems across a wide range of high-performance computing applications.

Since 2016, AMD has played a leading role in driving three other new bus / interconnect standards, such as CCIX, OpenCAPI, and Gen-Z. Like the CXL, these three efforts are driven by the need to create closer coupling and consistency between processors and accelerators, and to better exploit new and emerging memory / storage technologies.

Mark Papermaster of AMD has announced that the company has joined the CXL (Compute eXpress Link) consortium, a group whose goal is to offer users high bandwidth and low latency of interconnection between processors and external devices, allowing the creation smarter devices than current PCIe connection offerings. PCI-SIG is taking care of bandwidth, but CXL plans to offer something bigger.

Intel plans to support CXL through the PCIe 5.0 interconnect interface, which will allow the company to support both standards seamlessly. AMD may do the same in time, which means PC users can expect to see PCIe-style connectors on CXL-compatible devices.
