12-Core AMD Ryzen AI Max 390 Processor appeared on GeekBench

AMD Ryzen AI Max 390 processor appeared in the GeekBench running library, showing a total of 12 cores.

According to the runoff database information, the processor’s 32-bit Single Precision, 16-bit Half Precision, and 8-bit Quantized scores are 4733, 4944, and 13944, respectively.

Here’s a comparison between the Ryzen AI 9 HX 370 processor and the Ryzen AI 9 HX 370 processor:

GeekBench Criteria	Ryzen AI Max 390	Ryzen AI 9 HX 370	increase
32-bit single-precision	4733	4695	0.81% increase
16-bit half-precision	4944	4715	4.86% increase
8-bit quantization accuracy	13944	12669	10.46% increase

Sadly, the list doesn’t reveal much about key specs, such as the Ryzen AI Max 390’s boost clock rate.

The test system is an upcoming HP ZBook Ultra model with 64 GB of RAM, which effectively confirms that the Strix Halo will be dedicated to powerful workstation-class laptops.

AMD has an initial plan for three models on the Strix Halo processors, and these SKUs are expected to be named the Ryzen AI Max 300 series:

• The top-of-the-line Ryzen AI Max+ 395 will enable all 16-core Zen 5 architecture CPUs and 40CU-scale RDNA 3.5 GPUs on Strix Halo.
• The lower Ryzen AI Max 390 has a reduced CPU core count to 12;
• The Ryzen AI Max 385 is further emasculated with an 8-core CPU paired with a 32CU GPU.

AMD Strix Halo processors support 256-bit wide (equivalent to quad-channel DDR5) LPDDR5 memory. According to the blogger, Strix Halo can allocate up to 96GB of memory space to the GPU, and combined with ROCm support, it provides excellent professional performance for small workstations.
