These desktop processors are almost identical to the previous models (that’s the 3600X, 3800X, and 3900X). Same number of cores and threads, same power output, same cache. The only noticeable difference is a higher clock speed. Anandtech has a great breakdown:
AMD recommends AIO liquid cooling solutions for both the 3000X and 3000XT lines. Asetek coolers take up a majority of that list. Considering the 3000XT series optimizes on the manufacturing process, better cooling won’t just mean better thermal performance.
The boost clock speed increases aren’t huge, only 100-200MHz. We’re expecting the XTs to be better for overclocking, though we’ll have to wait until we get some units to test to know for sure.
But once these new XT chips release, their X counterparts are going to see a price drop. So if you’ve been waiting to upgrade to a 3600X or 3800X, wait a few weeks.
