AMD’s 12 Core Ryzen 3900 XT “Matisse Refresh” to Have a Boost Clock of 4.8GHz, 3800 XT & 3600 XT @ 4.7GHz

It seems that the specs of AMD’s Matisse refresh offerings have leaked, and they look pretty solid. With an aim to tackle the 10th Gen Intel Comet Lake-S K series CPUs, Team Red is planning to launch three new chips, the Ryzen 5 3600XT, the 3800XT, and the 3900XT. These are essentially higher-clocked variants of the vanilla 3600X, 3800X, and 3900X. Thanks to a Chiphell leak, we now know the exact specifications of the upcoming Matisse refresh family.

The Ryzen 5 3600XT and the Ryzen 7 3800XT are being speculated to be 300MHz faster than the vanilla 3600X and 3800X while the 12-core Ryzen 9 3900XT is said to boost 200MHz higher than the 3900X. It’s unlikely that AMD will change its Precision Boost 2 algorithm with the Matisse refresh, so the effective boost clocks in most scenarios will be slightly lower, think 4.6GHz in case of the 3600XT and 3800XT and 4.7GHz in the case of 3900XT. Regardless, you should be able to get to the marketed boost by enabling AutoOC and using a capable cooler, but that can’t be called “within spec”.

Furthermore, according to the Ryzen DRAM calculator 1usmus, the infinity fabric clock will also be higher with the new Matisse refresh CPUs. Instead of 1800MHz, the FCLOCK will be 2,000MHz, a healthy 200MHz improvement. This means that the inter-core latencies with the new Matisse refresh parts will also be tighter which will directly result in better gaming performance. Keep in mind that for the best performance, you’ll have to pair the CPUs with 2000MHz or 4000MT/s of dual-channel memory.
