AMD’s Ryzen 4000 APUs will feature the world’s first low-power octa-core processors, bringing desktop levels of performance to the notebook PC space. We’ve already seen many Renoir benchmarks and in nearly every test, they eat Intel’s Comet Lake CPUs for breakfast. Ice Lake manages to stay afloat in the single-threaded tests due to a superior IPC, but the low core count means it’s not effective in multi-threaded workloads. Today, we have a leaked CPU-Z benchmark of the Ryzen 7 4800H. Normally we wouldn’t share it, not being a real-world test and all that, but considering how well it performs, we just had to:
As you can see, the Ryzen 7 4800H, a 45W mobile CPU, manages to beat the Core i9-9900KF, a 150W+ desktop part in the multi-threaded benchmark. That’s absolutely remarkable. (https://cobblerexpress.com/) Even in the single-core test, the Renoir chip manages to stay in the race being marginally slower than the i9.
The source also shared the in-benchmark frequency and the resulting power draw, and to say that it’s impressive would be an understatement. The 4800H with a reported 3.35GHz clock in the Task Manager and 100% CPU utilization draws just 45W. In comparison, the competing Intel offering, the i9-9980HK draws an insane 138W in Cinebench. Granted, this isn’t a Cinebench test, but I’ll bet, the 9980H will draw at least 100W if not more in the same test.
AMD’s existing mobile Picasso APUs, while do offer comparable performance to their Intel competitors, in terms of battery life, they often fall short. With Renoir, that’s all set to change. You can read our architectural deep-dive of the Ryzen 4000 mobile lineup here.
