Mystery four-core, eight-thread AMD Rembrandt processor makes Geekbench debut

While AMD's Ryzen 6000 series of laptop processors have been out and about for a while, there are a few SKUs yet to be unveiled, namely the entry-level Ryzen 3 models. Currently, there is no telling as to when AMD could unveil them, but the day doesn't appear to be far, as the a new AMD Ryzen 6000 series processor, presumably the Ryzen 3 6300 or Ryzen 3 6400, just showed up on Geekbench.

The Geekbench listing doesn't explicitly state that the processor in question, which is simply denoted as AMD Eng Sample: 100-000000552-40_Y, indicating that it is an engineering sample. However, it bears the codename Rembrandt and has four cores/eight threads, which fits the bill perfectly for an entry-level CPU, likely the Ryzen 3 6400U or Ryzen 3 6300U. It has a base clock speed of 2.9 GHz and can turbo up to 4.1 GHz. The test rig appears to be an HP laptop running 16 GB of DDR5 RAM.

In Geekbench's CPU benchmark, the AMD Ryzen 3  6400U/Ryzen 3 6300U scores 1,321 and 4,261 in the single and multi-core test. The marginal performance uplift isn't surprising, given that Rembrandt uses a slightly upgraded version of the Zen 3 cores found on Cezanne. However, Rembrandt's RDNA2 iGPU accounts for remarkable performance gains in Geekbench's OpenCL benchmark, with the processor scoring 13,755. That represents a ~20% uplift in performance over the Ryzen 3 5400U, which used an ageing Vega iGPU.
