And that's a lot. In Geekbench some scores leaked, and while we don't trust geekbench scores, the specs however are listed in great detail. 

AMD Genoa ZEN4 based architecture will find its way into server and workstation CPUs, and thus specs are now leaked to some extent.

An engineering sample CPU is clocked at 1.2 GHz, not relevant since it's an ES sample, but noteworthy is that AMD has increased the L2 cache to 1 MB per core, that double the amount of its predecessor, which is a good thing.

This engineering sample does not appear to feature a 3D V-Cache. It has 128 MB of L3 cache. Even with the clock speed reduced, the Genoa CPU performs remarkably similarly to an EPYC 7513 in single core testing. The EPYC 7513 has a base speed of 2.6 GHz and a boost clock of 3.65 GHz, and it runs Ubuntu 20.04 LTS on both. It outperforms it on several of the subtests, such as navigation, SQLite, and HTML5. Speech recognition and rigid body physics are two areas where it gets close.

This is particularly remarkable given that the Genoa engineering sample operates at less than half the speed of the EPYC 7513. It is possible that it is working at a third of the normal speed. It is anticipated that AMD's Zen 4-based Genoa CPUs will be available later this year. In addition, models with up to 96 cores and 192 threads are envisaged, as well as 12-channel DDR5 memory and PCIe 5.0 expansion capabilities.
