5.2GHz AMD Zen 4 test CPU pops up in database and then vanishes
AMD's Zen 4 CPUs aren't expected until the second half of the year, but the leaks are already rolling in earnest, with the latest spotted by Petykemano (via Tom's Hardware) on the OpenBenchmarking site. The entry for the Phoronix benchmark sees an AMD engineering sample divulging some interesting tidbits about AMD's follow-up to Zen 3, including the fact that it is running at 5.21GHz, is an 8-core, 16-thread chip, and that it boasts integrated graphics in the form of the AMD GFX1036.
The original entry on OpenBenchmarking.org has since been removed, or at least hidden from prying eyes, although the power of the Wayback Machine means that it's still available if you fancy taking a look yourself. The entry for the Zen 4 chip was captured on May 9.
The CPU is identified as an «AMD Eng Sample 100-000000666-20_Y», although assuming that this follows a similar naming scheme as the existing Zen 3 chips, the 8-core, 16-thread configuration would logically make it the Ryzen 7 7800X. The fact that it has integrated graphics could also suggest that we're looking at a Ryzen 7 7800G here instead, although AMD could change its naming conventions if it has more APUs this time around.
That 5.21GHz clock speed is notable as it makes it a faster offering than anything has available from this generation, which tops out at 4.9GHz with the Ryzen 9 5950X. For comparison, the Ryzen 7 5800X, the chip that this engineering sample would appear to replace, has a maximum boost clock of 4.7GHz. A 500MHz boost is nothing to be sniffed at in this industry and, together with new architectural and process node improvements, this could lead to a serious performance jump for Zen 4 over the existing Zen 3 chips.
Zen 4 is being produced using TSMC's N5
