Intel’s 12th Gen Alder Lake processors are supposed to represent the largest performance and efficiency leap the chipmaker has managed in the last ten years or so. AMD, on the other hand, will be fielding its Zen 3 designs till the launch of the Zen 4 family near the end of the year. Out of these, Zen 3+ and the Ryzen 7 5800X3D are the most notable products. The former is a refinement of the Zen 3 core architecture using TSMC’s N6 (6nm) node to offer ultra-high power efficiency while the latter 3D stacks L3 cache for improved gaming performance.
Despite being the product of mere process refinements and firmware optimizations, the Ryzen 9 6900HS manages to hold its own against Intel’s Core i9-12900H. The two perform within 5% of now another in multi-threaded workloads despite the latter being a 14 core/20 thread part, and the former being limited to 8 cores/16 threads.
In both Cinebench R20, and R23, the Ryzen 9 6900HS is just 4-5% slower than the Core i9-12900H in the multi-threaded segment, while falling behind by 20-25% in single-core performance. It’s worth noting that both SoCs had a TDP of around 50W, and were tested on the ROG Flow notebooks. On the memory side, the 6900HS was paired with faster LPDDR5-6400 RAM while the 12900H was coupled with LDPPR5-5200 DIMMs.
This indicates that while single-threaded performance has increased quite substantially with Alder Lake, multi-threaded capabilities leave a lot to be desired. The fact that AMD is able to level with Intel with nearly half as many cores means that it won’t need to offer a 32 core alternative with Zen 4 to tackle Raptor Lake. With Raptor Lake, Intel aims to double the efficiency “Gracemont” core count, something that should help alleviate this deficiency.
