AMD Ryzen AI Max+ PRO 395 Linux Benchmarks: Outright Incredible Performance + Radeon 8060S Linux Graphics Performance

Citiraj:

The AMD Ryzen AI Max+ PRO 395 can work out fine on modern Linux distributions: as long as you're on a modern distribution like say Fedora Workstation 42 or Ubuntu 25.04 you should find the support in good standing. As long as you are on a somewhat recent Linux kernel version you should be in good shape for the compatibility/support while for the Strix Halo graphics obviously the newer the kernel and the newer the Mesa release will mean a better graphics experience. HP has kindly sent over their ZBook Ultra 14-inch G1a mobile workstation: it's a beast being powered by the top-end AMD Ryzen AI Max+ PRO 395 SoC with 16 cores / 32 threads and powerful integrated Radeon 8060S graphics, 128GB of system memory, a nice 14-inch 2.8K display, and other top-end features to provide a dominating laptop powerhouse.

Simply put, the AMD Ryzen AI Max+ PRO 395 delivers incredible performance potential that need it on the go. For those running heavy workloads from your laptop for portability, convenience, travel, or similar purposes, the AMD Ryzen AI Max+ PRO 395 opens a whole new realm of performance while still delivering good power efficiency. On average the AMD Ryzen AI Max+ PRO 395 was 1.42x the performance of the AMD Ryzen AI 9 HX 370 "Strix Point". Or a whopping 1.88x the performance of Intel Lunar Lake. But that's just the geo mean. If really diving into AI, code compilation, scientific computing, and other creator workloads and more the AMD Ryzen AI Max+ PRO 395 was commonly at 2x the performance or more of the high-end Strix Point SoCs.

AVX-512 performance + power efficiency shines with AMD Strix Halo

Citiraj:

When taking the geometric mean of more than 100 AVX-512 capable software packages/applications, having AVX-512 enabled as is the default meant 1.46x the performance compared to force-disabling AVX-512 on Strix Halo. AVX-512 provides very meaningful performance gains on AMD Zen 5 (and Zen 4) from AI workloads to scientific computing, video coding, JSON parsing, and other software able to leverage Advanced Vector Extensions 512. Meanwhile Intel's latest laptop and desktop processors do not support AVX-512. Very important for AMD Strix Halo laptops is that AVX-512 doesn't lead to any increase in power use. In fact, when looking at the CPU power consumption over the entire span of 100+ benchmarks carried out, AVX-512 disabled on the Ryzen AI MAX+ PRO 395 led to a 53 Watt average and with the default AVX-512 enabled state was a 51 Watt average for the SoC.

ROCm GPU compute performance with AMD Ryzen AI MAX+ "Strix Halo"

Citiraj:

Across 50+ benchmarks when taking the geometric mean for the workloads tested on all three laptops, the Ryzen AI MAX+ PRO 395 within the HP ZBook Ultra G1a was at 2.41x the performance of the popular Ryzen AI 9 HX 370 "Strix Point" SoC found within the Framework Laptop 13. 2.41x! Over the Intel Xe2 graphics within Lunar Lake was also 2.3x the performance, which would have been even worse off if not for last week's Compute Runtime release enhancing Lunar Lake with ULLS and other optimizations. Across the range of GPU compute benchmarks carried out, the Ryzen AI MAX+ PRO 395 had a 43 Watt average and a peak of 77 Watts. The Ryzen AI 9 HX 370 had a 23 Watt average and a 50 Watt peak while the Core Ultra 7 256V had a 15 Watt average and a 28 Watt peak. So going from Strix Point to Strix Halo with these ROCm GPU compute workloads had 1.87x the SoC power use but delivering around 2.4x the performance for a nice efficiency win.
