    temperatures in full load with the important mention that the system, the computer case is sitting with the intake, outside where its 1 to 3 C at the time, measurement taken in the morning

    when its 15 to 20 C at noon, the temperatures measured are higher

    now that reviews are available from all well known sites, a comparison can be made between the old 3900X and 5900X, most used processors

    the new generation is more power efficient and the 5900X is aprox 25% more powerful in CPU-Z tests while consuming around 10% more power

    the temperatures are a bit hotter on the 5900X than on 3900X so liquid cooling is a must

    the final decision would be the price. It would worth buying the new 5900X but only in the absence of some very good deals on the 3900X, otherwise, a 3900X is still good enough

    two useful aspects i would like to share here

    best memory for Zen 2 (Ryzen 3000) is between DDR4 3200 and DDR4 3600. There are plenty of info available on the internet regarding the Infinity Fabric but most important, DDR 3200 or DDR 3600 are not frequencies but data rates and the frequencies are half that value, so DDR 3200 means 1600 Mhz (that is why is called double data rate, DDR). Best performance is achieved in a synchronous operation 1:1 with a DDR4 3600 (1800 Mhz).

    second useful info is a java benchmark from the site techpowerup from the recently published review of the 5950X

    https://www.techpowerup.com/review/amd-ryzen-9-5950x/12.html

    few sites publish a java benchmark, that’s why is interesting, and with this benchmark is a closer as we can get to measure and compare SQ performance
