    since a number of questions have come up about the CPU and the multiplier.

    While this Xeon D-1541 loaner is a pre-release BIOS on a pre-release Rev. 2.00 motherboard, I still thought it might be helpful to publish the results of the ever-helpful HWiNFO64.

    What we have here is the Supermicro SuperServer SYS-5028D-TN4T with the X10SDV-TLN4F motherboard, comparing the original Xeon D-1540 with the slight speed boost (<5%) Xeon D-1541, to reveal some other differences. Both system have default BIOS settings. Don't know if these power-use differences will be present in the released Xeon D-1541 on the final Rev. 2.00 motherboard. At this time, it does appear that the step-down of the CPU when idle all the way down to about 0.80GHz seems to have a different effect on each of the power use of each system. Both have the same 4 x 32GB DIMMs, and both have the same 1 Samsung 950 PRO 512GB NVMe SSD. Yes, I moved the DIMMs and the M.2 storage from one system to the next for these tests.

    Description Watts GHz Ratio
    Xeon D-1540 / BIOS 1.0b / idle 24 2.0 x20
    Xeon D-1541 / BIOS 1.0c / idle 36 2.1 x21
    Xeon D-1540 / BIOS 1.0b / load 78 2.6 x26
    Xeon D-1541 / BIOS 1.0c / load 90 2.7 x27
