New details regarding AMD's Ryzen 6000 Rembrandt APU lineup based on the Zen 3+ architecture have been reported by reputable leaker, ExecutableFix. As per his latest tweet, it looks like the 4th Gen Ryzen Rembrandt line of APUs will be the only family to feature the mysterious AMD Zen 3+ core archiutecture.

As per the new details, AMD's next-generation Rembrandt Ryzen APUs will be based on the Zen 3+ and RDNA 2 GPU cores. But these aren't just any Zen 3 / RDNA 2 cores, the roadmap also mentions that the chips will be based on a 6nm process node. AMD is expected to retain TSMC's as its choice of fab for the Rembrandt CPUs and as such, we can expect around 20% higher density with better power consumption on the improved node.
