AMD has just lifted the embargo on the new Ryzen 5 3600XT, Ryzen 7 3800XT and Ryzen 3900XT processors. For starters, these processors shares the same Zen 2 architecture as the 3rd Generation Ryzen processors that were launched just last year. The addition of the postfix "XT" to the same models from last year does not bring about too much difference to these products. The three newly introduced processors only boasts higher clock speed.

Is that really just it? Are these processors' differences only in this slight bump in CPU frequency and nothing else? What we've found out through our test is that there's actually more than meets the eye.
AMD also explained that since most enthusiasts will not use the stock Wraith Prism coolers for the high end Ryzen 7 and Ryzen 9 processors, they have also decided to exclude the CPU cooler in the box. Could this be the end of the popular Wraith Prism coolers? Let's hope that they will still be included in the next generation Ryzen processors that's expected to be announced later in the year.
Testing Methodology and Setup
In this review, we are going to run our standard benchmark suites to see the performance results of the new AMD Ryzen 5 3600XT and Ryzen 7 3800XT. Unfortunately, as we do not have a Ryzen 5 3600X nor the Ryzen 7 3800X in our labs, we are unable to compare the performance difference between the XT and non-XT variants.
We will then try to overclock these processors and see if there's any difference when compared to its earlier versions.
The results were largely as what we can expect. As the Ryzen 7 3800XT is clocked slightly higher than the Ryzen 5 3600XT, it performs slightly better with single-threaded applications. As for multi-threaded applications, as the Ryzen 7 3800XT has 2 more cores than the Ryzen 5 3600XT, of course, it will perform better.
As for games, the performance difference is rather negligible. You can be sure that the Ryzen 5 3600XT will be good enough for any games that you play.
Power Consumption and Temperature
In an idle state, both systems consumed about 60W of power. As on load, the difference can be seen, as the Ryzen 7 3800XT uses 26W more than the Ryzen 3600XT.
Interestingly, even though the Ryzen 7 3800XT has two more cores than the Ryzen 5 3600XT, we measured identical temperature in both idle and load states for both processors.
Overclocking
The real difference of the new 3000 XT series processors, particularly the Ryzen 7 3800XT and Ryzen 5 3600XT is its overclocking capabilities. In our past review of the Ryzen 7 3700X and Ryzen 9 3900X, we required voltage in excess of 1.4V in order to achieve 4.3GHz on all cores, the new XT processors could reach even higher overclocked frequencies with lower voltage requirements.
For the Ryzen 5 3600XT (CPU-Z failed to register it as a XT CPU) , with just a mere 1.3V, we managed to achieve 4.45GHz. In this configuration, our stock AMD Wraith Prism was able to tame the heat in this overclocked state, and provided a Cinebench R20 score improvement from 3754 to 4010. That's a 8.4% increase in performance!
Similarly, the Ryzen 7 3800XT was able to overclock very well too. With the same 1.3V, the Ryzen 7 3800XT (CPU-Z failed to register it as a XT CPU) reached 4.4GHz. The Cinebench R20 score increased from 4982 stock configuration to 5346 in overclocked state. This is a 7.3% improve in performance.
Gamer Nexus also compared the new silicon with current processors from the 3rd Generation Ryzen processors and also found similar results. It seems that the newer CPUs does overclock better. We'll see if other reviewers are able to reach such overclocking profiles with their processors as well.
Conclusion
If you are deciding to upgrade from your current non XT Ryzen processor to a XT processor, it probably doesn't make sense, as the performance increase will be insignificant. You could simply overclock your current CPU to achieve that additional 100 or 200MHz for the same performance as the XT processor.
However, if you are looking to build a new PC, or are planning to upgrade from a 1st or 2nd generation Ryzen processor, you'd have more choices now. The new 3000 series XT processors will replace their non-XT versions at the same price point, providing more value to consumers. However, do take note that you won't get a stock AMD Wraith Prism Cooler for the Ryzen 9 3900XT and Ryzen 7 3800XT, which was previously available in their non-XT variant.
These new AMD Ryzen 3000 series XT processors seem to overclock well too. It would be an interesting product for enthusiasts who wishes to see how far they can push their system to get that extra performance. It would be interesting on how far overclockers can bring these new processors to.
