Price just dropped on this.

Way more power efficient than the X series, not much performance different.

    Those sites are balleux, don't use them for any rational comparison of CPUs or anything. If they compared potatoes I still wouldn't trust them.

    I don't like these dual CCD chips. Requires the Windows scheduler to really know what it is doing so it only spreads the load over one CCD. Else you get performance issues in games.

    If you are in the market for an AMD system for gaming my advice is 7700x or 7800x3d. One CCD, plenty of cores, no scheduling issues and plenty fast enough for other stuff unless you are into heavy duty productivity apps.

    What motherboard and cooling would you recommend for the 7800x3d?

    Do note the amazon title is wrong, it is a 9 series, their `Item model number` lower down is correct == ‎AMD Ryzen 9 7900.
    There is no 7 series 7900 see en.wikipedia.org/wik…zen

    Looking at your history that was the X series, not the more power efficient non-X

    I have been watching for a non-X price drop for months.

    non-X saves at least 50-100W power draw, which adds up over the years if you are a heavy user. (edited)

    I would love one of these. I have 12 cores/24 threads, but the technology is more than a dozen years old - so 2 CPUs at 95W and only just over 3GHz .

    Ignoring the IPC improvements, the power draw on my very old system is high. Yet, I still cannot afford the cost of this, a new motherboard, and the DDR5. (edited)

    AM5 CPU + DDR5 are now cheap and comparable in cost with AM4. Only the motherboards are more expensive than AM4.

    Not bad but waiting for 8000 series.
