Aspects include computing devices, apparatus, and methods implemented by the apparatus for implementing a hybrid input/output (I/O) coherent write request on a computing device, including receiving an I/O coherent write request, generating a first hybrid I/O coherent write request and a second hybrid I/O coherent write request from the I/O coherent write request, sending the first hybrid I/O coherent write request and I/O coherent write data of the I/O coherent write request to a shared memory, and sending the second hybrid I/O coherent write request without the I/O coherent write data of the I/O coherent write request to a coherency domain.
