The first benchmarks of AMD’s Ryzen AI 9 HX 370 “Strix Point” APU have been 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 up to 40% faster RDNA 3.5 GPU versus previous flagship, the Ryzen 9 8945HS
Well, that didn’t last long, AMD’s first unofficial benchmarks of its upcoming Ryzen AI 300 APUs started leaking out and they’re very impressive in their first showcase. The chip in question is the Ryzen AI 9 HX 370, which is a very big and confusing name for some, but we should get used to it as both Intel and AMD will be going the AI brand route in the future and we might see better hopefully in the future naming schemes. 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 four Zen 5 and eight Zen 5C configurations. This chip operates at boost clock speeds up to 5.1 GHz, offers 36 MB cache (24 MB L3 + 12 MB L2) and the Radeon 890M iGPU with 16 computing units or 1024 cores. So versus 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 is a huge gen-over-gen gain.
As for the Geekbench leak, it looks like we’re looking at an early example, as while it matches the base clock of 2.0 GHz, the log file shows a boost clock of around 4.2 GHz, which is below the highest rated clock speed of 5.1 GHz. .
AMD Ryzen AI “HX” APUs:
| CPU name | Architecture | Cores/Wires | Clock speeds (max.) | Cache (total) | AI capabilities | iGPU | TDP |
|---|---|---|---|---|---|---|---|
| Ryzen 9AI HX370 | Zen5 / Zen5C | 12/24 | 2.0 / 5.1 GHz | 36MB / 24MB L3 | 77 AI TOPs (45 TOPS NPU) | Radeon 890M (16 CU @ 2.9 GHz) | 28W (cTDP 15-54W) |
| Ryzen 7AI365 | Zen5 / Zen5C | 10/20 | 2.0 / 5.0 GHz | 30MB / 20MB L3 | TBD AI TOPs (45 TOPS NPU) | Radeon 880M (12 CU @ 2.9 GHz) | 28W (cTDP 15-54W) |
| Ryzen 7AI HX350? | Zen5 / Zen5C | 8/16 | To be determined | 24MB / 16MB L3 | TBD AI TOPs (45 TOPS NPU) | 12 RDNA 3+ CUs? | 28W (cTDP 15-54W) |
| Ryzen 5AI HX330? | Zen5 / Zen5C | 6/12 | To be determined | 20MB / 12MB L3 | TBD AI TOPs (45 TOPS NPU) | 8 RDNA 3+ CUs? | 28W (cTDP 15-54W) |
The APU is listed as the Ryzen AI 9 HX 170 with Radeon 880M iGPU, but it should be pointed out that AMD made a last-minute change and moved to a higher number. We’ve seen many Strix Point laptops on the Computex show floor that still haven’t been updated with the new Ryzen AI 300 branding and are using the older Ryzen AI 100 serial numbering.

As for 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 single-core and 14,316 points in multi-core tests. In the Geekbench 6.3.0 benchmark, the chip scored 2544 points in single-core and 14,158 points in multi-core tests. Finally, the RDNA 3.5 (Radeon 890M) iGPU scored 41,995 points in the OpenCL test.
The CPU performance of the Zen 5 cores on the Strix Point APU looks great, despite this being an early sample. We can expect the final performance to be much higher when the retail silicon comes at speeds up to 5.1 GHz.

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 scored a 7% lead in single-core, 20% lead in multi-core and a huge lead 40% gain in the graphics test, putting it on par with the RTX 2050 discrete GPU.
The important thing to keep in mind is that AMD is eliminating a fixed TDP with its new Ryzen AI 300 series, so there won’t be an HX, HS, H, or U SKU. Instead, manufacturers will have to decide for themselves which TDP target to use, as these chips can scale from 15W to 54W, so it will be harder to say what actual TDP this benchmark was running at. The default TDP is 28W, while the AMD Ryzen 9 8945HS has a default TDP of 45W. So if tested at standard that’s a big win, but if tested at a lower TDP, say 15-20W, then this result is even more impressive.
AMD’s Ryzen AI 300 CPUs will be available from July 2024 through various OEM partners, and we can expect better availability from holiday 2024 or the fourth quarter.
