  2. Coherent Accelerator Processor Interface - Wikipedia

    en.wikipedia.org/wiki/Coherent_Accelerator...

    OpenCAPI Memory Interface (OMI) is a serial attached RAM technology based on OpenCAPI, providing low latency, high bandwidth connection for main memory. OMI uses a controller chip on the memory modules that allows for technology agnostic approach to what is used on the modules, be it DDR4, DDR5, HBM or storage class non-volatile RAM. An OMI ...

  3. High Bandwidth Memory - Wikipedia

    en.wikipedia.org/wiki/High_Bandwidth_Memory

    High Bandwidth Memory (HBM) is a computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM) initially from Samsung, AMD and SK Hynix.It is used in conjunction with high-performance graphics accelerators, network devices, high-performance datacenter AI ASICs, as on-package cache in CPUs [1] and on-package RAM in upcoming CPUs, and FPGAs and in some supercomputers ...

  5. RLDRAM - Wikipedia

    en.wikipedia.org/wiki/RLDRAM

    Reduced Latency DRAM (RLDRAM) is a type of specialty dynamic random-access memory (DRAM) with a SRAM-like interface originally developed by Infineon Technologies.It is a high-bandwidth, semi-commodity, moderately low-latency (relative to contemporaneous SRAMs) memory targeted at embedded applications (such as computer networking equipment) requiring memories that have moderate costs and low ...

  6. RDMA over Converged Ethernet - Wikipedia

    en.wikipedia.org/wiki/RDMA_over_Converged_Ethernet

    Network-intensive applications like networked storage or cluster computing need a network infrastructure with a high bandwidth and low latency. The advantages of RDMA over other network application programming interfaces such as Berkeley sockets are lower latency, lower CPU load and higher bandwidth. [6]

  7. InfiniBand - Wikipedia

    en.wikipedia.org/wiki/InfiniBand

    InfiniBand (IB) is a computer networking communications standard used in high-performance computing that features very high throughput and very low latency.It is used for data interconnect both among and within computers.

  8. Compute Express Link - Wikipedia

    en.wikipedia.org/wiki/Compute_Express_Link

    There is no bandwidth increase from CXL 1.x, because CXL 2.0 still utilizes PCIe 5.0 PHY. On August 2, 2022, the CXL Specification 3.0 was released, based on PCIe 6.0 physical interface and PAM-4 coding with double the bandwidth; new features include fabrics capabilities with multi-level switching and multiple device types per port, and ...
