A three-year-old AMD Ryzen 7 7735HS is proving it still has plenty of life left, even when compared to a newer Ryzen AI 7 445 system. Recent benchmark and stress-test results show that, in sustained CPU-heavy workloads, the older 7735HS platform can deliver noticeably stronger performance—reminding buyers that “newer” does not always mean “faster,” especially when power limits and cooling come into play.
The Ryzen 7 7735HS paired with Radeon 680M graphics, as seen in the GMK NucBox K16, holds up extremely well in multi-core benchmarks. In Cinebench R15 Multi, it posts around 72 points, while the Ryzen AI 7 445 with Radeon 840M in a Lenovo Yoga 7 2-in-1 16AGP11 lands closer to 53 on average. Cinebench R23 Multi tells a similar story, with the 7735HS system scoring roughly 72 versus about 53 for the Ryzen AI machine. That kind of gap is hard to ignore if your daily tasks include long renders, code compiles, heavy multitasking, or other workloads that keep all cores busy.
Stress testing also reinforces the same takeaway: the Ryzen 7 7735HS machine sustains higher output under load. In a Prime95 stress run, the 7735HS setup averages about 74, while the Ryzen AI 7 445 system averages about 57. In practical terms, that suggests the older chip (or at least that specific device configuration) is able to maintain stronger sustained performance, which is often what matters most for productivity users.
On the graphics side, the comparison is more nuanced. With a 720p FurMark GPU stress test, the Radeon 840M device shows a higher average result (around 56) versus the Radeon 680M device (around 50). That points to the newer integrated GPU having advantages in pure GPU stress scenarios, even if the CPU results lean the other way.
Gaming results from Cyberpunk 2077 at 1080p Ultra without FSR are especially interesting because they don’t follow the simple “new wins” pattern. The Ryzen 7 7735HS with Radeon 680M averages about 68 FPS, while the Ryzen AI 7 445 with Radeon 840M averages about 46 FPS. That’s a significant spread, and it highlights how real-world gaming performance can vary based on the full system—drivers, memory configuration, power tuning, and thermal headroom can all swing results.
Power draw at idle is another area where newer platforms often shine, and the numbers reflect that. The Ryzen AI 7 445 system idles around 3.2 watts, while the Ryzen 7 7735HS system sits closer to 7.6 watts. If battery life and efficiency are top priorities, that lower idle draw could matter a lot for lightweight everyday use.
The big takeaway for anyone shopping for a mini PC or thin-and-light laptop is simple: don’t dismiss the Ryzen 7 7735HS just because it isn’t the newest option. For CPU-driven workloads and even some demanding gaming scenarios, it can still compete—and in these results, it often comes out ahead. At the same time, newer Ryzen AI hardware can bring meaningful efficiency improvements and potentially stronger integrated graphics in certain tests, making the “best” choice depend on whether you care more about sustained CPU performance, GPU-focused tasks, or power efficiency.
