Updated | AMD Ryzen 9 3900XT manages credible results on Geekbench placing it in the company of the Ryzen 9 3900X and Intel Core i9-10900K but its predecessor offers better value

A Matisse Refresh AMD Ryzen 9 3900XT desktop processor has been spotted on Geekbench 5.1 along with a Gigabyte X570 Aorus Master motherboard. The 12-core chip recorded results that put it in the same ballpark as the Ryzen 9 3900X and Intel Core i9-10900K, but it is likely better scores can be squeezed out of it yet.
Update: Much better results for the 3900XT have been unearthed.
Daniel R Deakin,

Update June 24: As expected, much better results for the AMD Ryzen 9 3900XT have now been spotted on Geekbench (v5.2). The single-core score was an impressive 1,413 points while the multi-core score was 12,970 points. These latest results make the Matisse Refresh chip a much more attractive prospect for desktop PC builders.

Original story:

An AMD Ryzen 9 3900XT has been discovered by Tum Apisak being tested on Geekbench 5.1. In combination with a Gigabyte X570 Aorus Master board, the upcoming desktop processor recorded a single-core score of 1,324 points and a multi-core score of 10,945 points. While the single-core result is particularly good, especially for an AMD part, more could have been expected from the 12-core Matisse Refresh processor in the multi-core benchmark.

We have tested both the Ryzen 9 3900X and Intel Core i9-10900K on Geekbench 5.1 and the results are not too dissimilar to those recorded by this particular AMD Ryzen 9 3900XT sample. As can be seen in the comparison table below, the 10-core Comet Lake chip with the TDP advantage leads in the single-core test, although as mentioned above the Ryzen 9 3900XT isn’t leagues behind.

You would expect an AMD processor, especially one with 12 cores, to do well in the multi-core test but it is not a Zen 2 part that takes the lead in this benchmark. It is the 10-core i9-10900K that again has the highest score here, while the Ryzen 9 3900XT with its lower boost clock (4.7 GHz vs. 4.8 GHz (all cores) & 5.3 GHz (single core)) has to settle for second place in this particular comparison.

However, more can be expected from the Matisse Refresh chip, which will be available to buy for US$499 from July 7. The recorded maximum frequency the Ryzen 9 3900XT reached on Geekbench 5.1 was 4.57 GHz, so there is still a little bit more juice to be squeezed out there. The sample was also at stepping level 0, so future revisions should optimize its performance even further. But with the Ryzen 3900X now available for US$399.99 you have to ask yourself if an extra 100 MHz is worth an extra US$100, even if AMD claims the XT Refresh offers greater boost clock consistency.
