12-core 20% faster in multi-threading, 40% faster GPU performance of the “Radeon 890M” compared to the 8945HS

The first benchmarks of AMD's Ryzen AI 9 HX 370 “Strix Point” APU have leaked, showing some big increases in both CPU and GPU performance with Zen 5 and RDNA 3.5 cores.

AMD Ryzen 9 AI HX 170 APU leak shows up to 20% faster Zen 5 CPU and up to 40% faster RDNA 3.5 GPU compared to the previous flagship Ryzen 9 8945HS

Well that didn't take long, AMD's first unofficial benchmarks of the upcoming Ryzen AI 300 APUs have leaked and they are very impressive in their initial presentation. The chip in question is the Ryzen AI 9 HX 370, which is a very big and confusing name for some, but we'll have to get used to it as both Intel and AMD will be going the AI ​​branding route in the future and hopefully we'll see better naming schemes in the future. So let's start with the specs.

The AMD Ryzen AI 9 HX 370 APU is part of the Ryzen AI 300 “Strix Point” family and features a 12-core and 24-thread chip with a configuration of four Zen 5 and eight Zen 5C. This chip runs at up to 5.1 GHz boost clock, offers 36 MB cache (24 MB L3 + 12 MB L2) and the Radeon 890M iGPU with 16 compute units or 1024 cores. So compared to the previous flagship, the Ryzen 9 8945HS, you get 50% more cores/threads, 33.3% more compute units and 3.12x the NPU performance, which are great improvements over the generation.

As for the Geekbench leak, it looks like we're dealing with an early sample considering that while it matches the base clock speed of 2.0GHz, the log file shows a boost clock speed of around 4.2GHz, which is lower than the highest reported clock speed of 5.1GHz.

AMD Ryzen AI “HX” APUs:

The APU is mentioned as Ryzen AI 9 HX 170 with Radeon 880M iGPU, but it should be noted that AMD made a last-minute change and moved to a higher number. We saw many Strix Point laptops at the Computex show that have not yet been updated with the new Ryzen AI 300 branding, using the older Ryzen AI 100 series numbering.

Ryzen 9 AI HX 370 APU benchmark leak (Geekbench 6.3.0) Result:

Ryzen 9 AI HX 370 APU benchmark leak (Geekbench 5.4.5) Result:

Let's get to the numbers: The AMD Ryzen 9 AI HX 370 APU was tested in Geekbench 5, Geekbench 6 and the OpenCL tests. In Geekbench 5.4.5, the chip scored 1847 points in the single-core and 14,316 points in the multi-core test. In the Geekbench 6.3.0 benchmark, the chip scored 2544 points in the single-core and 14,158 points in the multi-core test. Finally, in the OpenCL test, the RDNA 3.5 (Radeon 890M) iGPU scored 41,995 points.

The CPU performance of the Zen 5 cores on the Strix Point APU looks great, despite this being an early model. We can expect the final performance to be significantly higher when the retail chip ships at up to 5.1GHz.

Compared to the AMD Ryzen 9 8945HS APU, the flagship of the Hawk Point series, the AMD Ryzen AI 9 HX 370 “Strix Point” APU achieved a 7% lead in the single-core section, 20% in the multi-core section, and a massive 40% gain in the graphics test, putting it on par with the discrete RTX 2050 GPU.

The most important thing to keep in mind is that with its new Ryzen AI 300 series, AMD is eliminating a fixed TDP, so there will be no HX, HS, H, or U SKU. Instead, manufacturers will have to decide for themselves what TDP target they want to use, as these chips are scalable from 15W up to 54W, so it will be harder to determine the actual TDP this benchmark ran at. The default TDP is 28W, while the AMD Ryzen 9 8945HS has a default TDP of 45W, so if testing at the default setting, that's a big win, but if testing at a lower TDP of, say, 15-20W, this result is even more impressive.

AMD's Ryzen AI 300 CPUs will be available through multiple OEM partners starting in July 2024, and we can expect better availability starting in the 2024 holiday season or in Q4.
