The first benchmarks for AMD's Ryzen 9 6900HX APU have recently leaked. According to the results, the AMD Ryzen 9 6900HX APU is an improvement over the Ryzen 9 5900HX, but neither surpasses Intel's flagship Alder Lake APU , which is the most recommended for laptops.
The AMD Ryzen 9 6980HX and Ryzen 9 6900HX APUs are going to be the flagship of AMD's line of Rembrandt-H chips for laptops. The processors will feature the new Zen 3+ cores, which are upgraded versions of those featured in Cezanne's Zen 3 lineup and use the new 6nm architecture to deliver higher clock speeds and faster performance.
The first Zen 3+ APUs debut
The AMD Ryzen 9 6900HX will offer 8 cores and 16 threads, 16 MB of L3 cache, and 4 MB of L2 cache. The base clock speed of both chips is 3,30 GHz, and the boost clock speed is 4,90 GHz. The HX series processors will have a wider thermal range and a TDP exceeding 45 W.
One of the biggest changes in the range will be the incorporation of the AMD RDNA 2 graphics architecture, with what they will have with the Radeon 680M GPU, with 12 calculation units or 768 cores, which will work at around 2 GHz. Finally, the APUs will feature LPDDR4X and DDR5 options for increased bandwidth.
In the Geekbench 5 benchmark of the Ryzen 9 6900HX, using a Lenovo 82RG laptop with 32GB of memory, it achieved a score of up to 1616 points in single-threaded mode and 10151 in multi-threaded mode. The previous generation AMD Ryzen 9 5900HX averaged 1417 points in single-threaded mode and 7658 in multi-threaded mode, representing a 14% increase in single-core CPU performance and a 33% increase in multi-core performance. This additional performance comes from the optimized 6nm node , which allows for more stable clock speeds compared to Cezanne.
But compared to Intel's Alder Lake Core i9-12900H benchmark, Intel beats the Ryzen 9 6900HX benchmark by 21% in single-thread performance and 44% in multi-thread performance. But it does so with much higher power consumption, which limits the laptop's mobility, although this matters to those who can't keep the laptop plugged in for very long throughout the day.
