AMD refreshed its Ryzen AI family this year with the new Ryzen AI 400 series which replaces last year’s Ryzen AI 300 series. Fans looking for substantial improvements may be disappointed, however, as the Ryzen AI 400 series only offers slight improvements over the Ryzen AI 300 series. Some older generation Ryzen 7 CPUs may even outperform the latest Ryzen AI 7 CPUs when it comes to specific tasks.
The tables below compare the Ryzen AI 7 445 processors to the three-year-old Ryzen 7 7735HS Ryzen 7 7735HS processor, found in the Lenovo Yoga 7 2-in-1 16 and GMK NucBox K16 respectively. The older Zen 3 processor outperforms the new Zen 5 processor by 10-15% in most multi-core benchmarks, including CineBench and 7-Zip. In contrast, the new Zen 5 processor consistently outperforms the Zen 3 processor on GeekBench, single-core benchmarks, and HWBOT x265 decode/encode.
The performance gap between the two CPUs can be partially attributed to the greater number of cores on the Ryzen 7 7735HS than on the Ryzen AI 7 445 (8 vs. 6), so raw multithreaded workloads run slightly faster on the older CPU, but also more efficiently on the older CPU. recent.
Despite the performance differences mentioned above, the new Zen 5 CPU is still arguably the better option for most users thanks to its integrated NPU and superior power efficiency. By running Cyberpunk 2077For example, our Ryzen AI 7 445 Radeon 840M system would consume approximately 35% less power while delivering similar refresh rates to our Ryzen 7 7735HS Radeon 680M system. For a general-purpose or multimedia-focused PC, the Zen 5 CPU is objectively the most balanced processor, even if it sacrifices a bit of multithreaded performance along the way.
