AMD Ryzen AI 9 365 Zen 5 engineering machine test released: SPEC 2017 integer IPC increased by about 10%, Geekbench about 15~17%

According to news from this site on June 22, blogger David Huang tested a laptop engineering machine equipped with Strix Point Ruilong AI 9 365 processor and briefly analyzed the performance of the mobile Zen 5 core.

Processor parameters

According to reports, the Strix Point series will launch with two SKUs, HX 370 and 365, both of which only support FP8 packaging. When first launched, it only supported LPDDR5x memory, and the platform tested this time was LPDDR5x-7500 32GB.

Strix Point adopts a native 12-core design and is composed of two asymmetric CCXs:

CCX0: 4 Zen 5 Youth Edition large cores, with 16 MB L3 cache

Zen 5 Youth Edition large core: compared In the full version of Zen 5 for desktop/server, the maximum frequency is reduced from 5.7 GHz to 5.1 GHz, the SIMD throughput is halved, and the corresponding L1 vector load bandwidth is also halved.

CCX1: 6 or 8 Zen 5c small cores, with 8 MB L3 cache

Zen 5c small core: using the exact same microarchitecture as the large core, continuing to reduce the Fmax target at the back-end physical design level to reduce area , frequency does not exceed 4 GHz.

The blogger actually measured the 365 small core frequency to be 3.3 GHz. The specific frequency configuration of the HX 370 needs to be tested in the future.

Actual performance measurement

SPEC CPU 2017

In the SPEC CPU 2017 rate-1 test, due to some sub-items hitting the temperature wall, it is limited to 4.8GHz. The test results are as follows:

With the previous generation Phoenix 7840U Compared with the Zen 4 core on the processor, Strix Point's Zen 5 core achieved an integer IPC improvement of 9.71%, while the Zen 5c core achieved an improvement of 10.47%. Looking at the specific sub-items:

500.perlbench_r has a larger improvement , Reached 24%5 525.x264_r

almost no performance improvement

531.deepsjng_r

even decreased performance

Geekbench 5 / 6

In the GeekBench 5 /6 test, Zen 5's IPC increased to 15.28 % and 17.66%, which is better than the SPEC CPU 2017 int rate improvement and more in line with AMD's official claim of 16% improvement.
