The first benchmarks of AMD's Ryzen AI 9 HX 370 “Strix Point” APU have leaked and they show some big improvements 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 40% faster RDNA 3.5 GPU vs previous flagship, Ryzen 9 8945HS

Well it didn't take that long, the first unofficial benchmarks of AMD's upcoming Ryzen AI 300 APUs have started to trickle out and they're pretty impressive in their first showcase. The chip in question is the Ryzen AI 9 HX 370, which is a big and confusing name for some, but we'll have to get used to it as both Intel and AMD will go the AI ​​branding route in the future and we'll see better. can. Hopefully future naming schemes. So let's start with the specifications.

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 in a four Zen 5 and eight Zen 5C configuration. The chip runs at up to 5.1 GHz boost clock, 36 MB cache (24 MB L3 + 12 MB L2), and offers a Radeon 890M iGPU with 16 compute units or 1024 cores. So compared to the previous flagship, the Ryzen 9 8945HS, you're getting 50% more cores/threads, 33.3% more compute units, and 3.12x NPU performance, which is a huge generation-over-generation advantage.

Coming to the Geekbench leak, it looks like we're looking at an early sample considering that while it matches the 2.0 GHz base clock, the log file shows a boost clock of around 4.2 GHz which is its highest. Rated clock rate is less than 5.1 GHz. .

The APU is mentioned as Ryzen AI 9 HX 170 with Radeon 880M iGPU but it should be mentioned that AMD made a huge last minute change and went to a higher number. We've seen a number of Strix Point laptops on the Computex show floor that haven't yet been updated with the new Ryzen AI 300 branding and use 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:








Coming to the numbers, the AMD Ryzen 9 AI HX 370 APU was tested in the Geekbench 5, Geekbench 6, and OpenCL tests. In Geekbench 5.4.5, the chip scored 1847 points in single-core and 14,316 points in multi-core tests. 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 pretty good despite being an early sample. When retail silicon ships with 5.1 GHz we can expect the final performance to be much higher.








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

The most important thing to keep in mind is that with their new Ryzen AI 300 series, AMD is doing away with a set TDP so there won't be an HX, HS, H, or U SKU. Instead, manufacturers will have to decide for themselves what TDP target they want to use, as these chips can measure anywhere from 15W to 54W, so it's hard to tell what standard TDP they'll run at. Is. Default TDP is 28W while AMD Ryzen 9 8945HS default TDP is 45W. So if tested at default, this is a huge gain but if tested at a lower TDP, 15-20W, the result is even more impressive.

AMD's Ryzen AI 300 CPUs will be available from July 2024 through several OEM partners and we can expect better availability from the start of the 2024 holiday season or Q4.
