AMD’s Rembrandt Based APU Tested, Features the Zen3+ Architecture

According to Geekbench, AMD may have plans to release an entry level mobile Rembrandt based APU for laptops.

This APU features the Zen 3+ (6nm TSMC) process which is an optimized variant of AMD’s 7nm based Zen 3 architecture. The graphics solution used in this APU utilizes AMD’s RDNA 2 architecture. 

Geekbench shows that this SKU has the OPN code, “100-000000552-40_Y” which may not indicate much. Other specifications point towards a 4 cores / 8 threads CPU running at a base frequency of 2.90GHz. The base clock frequency can be boosted upto 4.1GHz.

Suited with 8MB of L3 cache and 2MB of L2 cache, this APU ships with the RDNA 2 based “GFX1035” GPU. This GPU has 3 compute units and 192 stream processors runing at a clock speed of 1600MHz.
