AMD’s Entry-Level & Quad Core Rembrandt APU Spotted & Benchmarked: Rocks 4 Zen 3+ & 3 RDNA 2 Cores

AMD might be planning to release entry-level Rembrandt Laptop APUs based on the Zen 3+ and RDNA 2 core architecture as indicated in a leak within the Geekbench 5 database discovered by Benchleaks.

AMD Rembrandt APUs Might Be Getting Quad Core Variants For Entry-Level Laptops

A recent entry on the Geekbench 5 database shows a brand new AMD Rembrandt APU which has the OPN code as "100-000000552-40_Y". There's no model name attached to this chip but it's listed as a "Rembrandt" part and the specifications suggest that the chip features 4 cores and 8 threads based on the Zen 3+ core architecture. The Zen 3+ core architecture is an optimized variant of the 7nm Zen 3 architecture that utilizes a 6nm process node from TSMC & delivers increased efficiency for laptops.

So far we know of two RDNA 2 integrated GPUs featured on the existing Rembrandt APU lineup. We have the Radeon 680M which features 12 Compute Units, we have the Radeon 660M which features half the units of its bigger brother at 6 and the new chip will have half the CUs of the 660M. It is likely that this chip will be branded as the Radeon 640M though we cannot say for sure.

So far, the only quad-core APUs within the Ryzen laptop lineup are the ones within the Barcelo family such as the Ryzen 3 5425U but that has a lower base and boost clock speed of 2.7 / 4.1 GHz. The APU rocks 6 Compute Units but is based on the older Vega GPU core and also runs at a lower 1500 MHz clock speed. The laptop this chip leaked within was an HP mt845 "Mobile Thin Client' design and comes with 16 GB of DDR5 memory.

Based on the performance results, the AMD Rembrandt Quad Core APU performs nearly identical to the Ryzen 3 5425U "Barcelo" chip which might have something to do with its ES nature. As for the GPU, the 3 RDNA 2 Compute Units offer similar performance as a Vega 11 iGPU with 11 CUs. Overall, the chip looks to be a solid entry-level solution that should be placed within the Ryzen 3 APU range. It is not known when AMD would launch its entry-level Rembrandt APUs but based on this leak, we might be looking at designs coming in real soon!
