The leaks, posted over on the Chiphell forums, indicate that AMD's Matisse Refresh chips might be more potent than we thought. The Ryzen 9 3900XT's single-core score was particularly interesting. With a score of 542, it narrowly beat out Intel's 5.3 GHz Core i9-10900K, until now the fastest processor we've seen in terms of single-core performance. The feat is even more impressive considering that the 4.8 GHz Ryzen 9 3900XT is clocked 500 MHz lower than the Comet Lake S Core i9-10900K.
The AMD Ryzen 5 3600XT likewise appears to deliver impressive single-threaded performance relative to the Comet Lake S competition. The Ryzen 5 3600XT scored 531 in the single-core test. This is higher than the Core i7-10700K, which manages just 521. It's also higher than the Intel Core i9-10900 and matches the AMD Ryzen 9 3950X, although the latter two parts benefit from a higher core count.
The excellent single-threaded performance figures posted by the Matisse Refresh parts spell bad news for Comet Lake. AMD's upcoming Ryzen 4000 series is expected to deliver higher clocks and an IPC improvement of over 15 percent. If AMD brings its Ryzen 4000 parts to market in the months to come, Comet Lake S runs the risk of losing both the gaming productivity fights.
