Unable to determine whether Intel® Xeon® w7-2495X Processor supports Intel® Data Direct I/O Technology (Intel® DDIO).
Intel® Data Direct I/O Technology was first introduced with the Intel® Xeon® E5 family and has been consistently supported in subsequent models.
The Intel® Xeon® w7-2495X Processor supports Intel Data Direct I/O Technology (Intel DDIO).
This innovative feature enables PCIe devices to write data directly into a subset of the L3 cache, significantly reducing latency for core data consumption from PCIe devices.
Additionally, it allows PCIe devices to read data directly from the L3 cache, bypassing memory access. This feature is typically enabled by default in the BIOS, providing optimized performance out of the box.
