The first official reference to the 'AMD Ryzen 9000 series' gives Zen 5 a name and hints at an imminent release date

pcgamer.com:

We've suspected AMD's Granite Ridge family of Zen 5 based processors might show their faces soon, given that AMD has already said it's aiming for a launch in the second half of this year, and CEO Dr. Lisa Su is set to deliver the Computex keynote on June 3. Now Gigabyte has released a BIOS update for several of its AM5 series of motherboards in anticipation of the new chips, and it seems to confirm that they'll be called the AMD Ryzen 9000 series.

In a news post on the company website, the Gigabyte AM5 X670, B650 and A620 motherboards are confirmed to receive boot up support for «the coming AMD Ryzen™ 9000 series», with the most recent AGESA 1.1.7.0 beta BIOS. 

While we've already seen leaks suggesting this name would be used for the new chips, this is the first official announcement that seems to confirm it.

While it's far from certain that the chips will be announced at Computex in June, it seems like motherboard manufacturers are busy preparing their boards for the new chips' imminent release. Intel's competing next-gen Arrow Lake chips have still yet to break cover, although recent rumours have suggested that Team Blue's new CPUs may be closer to release than previously thought, with a potential release in the first half of this year.

In terms of what to expect from Zen 5 when it comes to performance, a recent post by leaker Kepler_L2 has suggested that the new chips are over 40% faster than Zen 4 in the SPEC benchmark. 

While performance numbers at this point are to be taken with an appropriately huge dose of salt, if that performance leap turns out to be true we may be looking at some particularly fast CPUs compared to the previous generation, which weren't exactly slouches in the benchmarks to begin with.
