AMD announced its Ryzen 6000 “Rembrandt” processors for notebooks and gaming laptops during its CES 2022 keynote the other day. Based on TSMC’s 6nm node, and featuring the upgraded RDNA 2 integrated graphics, the next-gen Ryzen APUs bring a staggering 2x increase in graphics performance, also becoming the first Zen design to touch the 5GHz mark. The integrated RDNA 2 graphics on Rembrandt are also the first to feature dedicated ray-acceleration units for ray-box/triangle intersections.
This speeds up games with DirectX 12 Ray-tracing, something that will become the norm in the coming years. The Ryzen 7 6800U is up to a whopping 300% faster than the Intel Gen 12 graphics featured on the Tiger Lake-U flagship (1165G7). The RDNA 2 iGPU also manages to one-up NVIDIA’s GeForce MX450 dGPU consistently across a variety of titles. The performance gains depend on the bottleneck. For example, in Doom Eternal, it’s both the memory subsystem and the shaders, making the 6800U considerably faster than its rivals.
There is, however, one flaw with AMD’s benchmark methodology (as pointed out by @aschilling on Twitter). The Ryzen 6000 mobile processors which have a nominal TDP of 28W (same as Intel’s Tiger Lake-U SKUs) are being compared to the 15W Ryzen 5000 APUs. That’s a nearly 2x increase in TDP for a 2x uplift in graphics performance and a 1.3x jump in CPU performance.
While it wouldn’t be fair to discount the advances in GPU performance brought about by Rembrandt (making it the fastest iGPU in the industry by a long margin), the CPU performance is largely the same as Cezanne. As such, some users will be better off opting for the lower-end Cezanne SKUs than Rembrandt as the RDNA 2 GPUs on the latter are limited to the higher-end offerings.
