AMD Ryzen 6000 Rembrandt Yellow Carp Navi 2x RDNA 2 iGPU to feature DCN 3.1 with added low-power states and 2 MB L2 cache per shader array but no Infinity Cache

[Redaktion]

AMD's upcoming Rembrandt Yellow Carp APUs for laptops will feature Navi 2x RDNA 2 iGPUs without Infinity Cache similar to what we've known for Van Gogh. Rembrandt will bring LPDDR5/DDR5, PCIe Gen 4, USB4 support on a 6 nm Zen 3+ architecture. It's RDNA 2 iGPU will use an upgraded DCN 3.1 engine with added low-power clock states and 2 MB L2 cache per shader array with six CUs.

Hopefully Van Gogh will be much more power efficient than TGL-UP4.
Intel's 9 watt UP4 has been very underwhelming.

How much power each CU have?
Ps5 36cu in non overclock mode is at 9 teraflops, (yes tf, didnt represent much but a simple illustration number)

Lets say the 6nm low power cu retain 80% performance of the highpower ps5 cu. At 12 cu it might be at 2.4 tf or
Slightly more powerful than the ol 1050 ti and pretty close to 1650.

It's about time that AMD takes the laptop market seriously. Ryzen is already a great mobile CPU, but lacked the proper IO to fight with TB3 in Intel platforms. Furthermore, that aging Vega iGPU was more suited to the budget market than the new Intel Xe iGPUs. Intel was beating the AMD Vega iGPUs in efficiency, usefulness for video encoding/decoding in the "new normal", and it even had a slight performance edge (not that anyone should push these iGPUs for gaming or rendering workloads).

DDR5 is a step in the right direction to future proof the platform, PCIe 4 is also nice but not really a priority for most laptops (i.e., the power constraints will likely make it perform at the later PCIe 3 levels either way).

All-in-all, I see no reason why anyone would buy the lackluster 2021 offerings when it's clear that 2022 is the year that AMD will finally wake-up.
