The first benchmarks of AMD’s Ryzen AI 9 HX 370 “Strix Point” APU have leaked and they show some big uplifts in both CPU & GPU performance with Zen 5 & RDNA 3.5 cores.
AMD Ryzen 9 AI HX 170 APU Leak Shows Up To 20% Faster Zen 5 CPU & Up To 40% Faster RDNA 3.5 GPU Versus Previous Flagship, The Ryzen 9 8945HS
Well that didn’t take so long, AMD’s first unofficial benchmarks of its upcoming Ryzen AI 300 APUs have started to leak out and they are 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 have to get used to it as both Intel and AMD will be going into the AI branding route in the future and we might see better naming schemes in the future, hopefully. 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 that features a four Zen 5 and eight Zen 5C configuration. This chip runs at up to 5.1 GHz boost clocks, offers 36 MB of cache (24 MB L3 + 12 MB L2), & the Radeon 890M iGPU with 16 compute units or 1024 cores. So versus the previous flagship, the Ryzen 9 8945HS, you are getting 50% more cores/threads, 33.3% more compute units, and 3.12x the NPU performance which is great gen-over-gen gains.
Coming to the Geekbench leak, it looks like we are 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 below its highest-rated clock rate of 5.1 GHz.
AMD Ryzen AI “HX” APUs:
| CPU Name | Architecture | Cores / Threads | Clock Speeds (Max) | Cache (Total) | AI Capabilities | iGPU | TDP |
|---|---|---|---|---|---|---|---|
| Ryzen 9 AI HX 370 | Zen 5 / Zen 5C | 12/24 | 2.0 / 5.1 GHz | 36 MB / 24 MB L3 | 77 AI TOPs (45 TOPS NPU) | Radeon 890M (16 CU @ 2.9 GHz) | 28W (cTDP 15-54W) |
| Ryzen 7 AI 365 | Zen 5 / Zen 5C | 10/20 | 2.0 / 5.0 GHz | 30 MB / 20 MB L3 | TBD AI TOPs (45 TOPS NPU) | Radeon 880M (12 CU @ 2.9 GHz) | 28W (cTDP 15-54W) |
| Ryzen 7 AI HX 350? | Zen 5 / Zen 5C | 8/16 | TBD | 24 MB / 16 MB L3 | TBD AI TOPs (45 TOPS NPU) | 12 RDNA 3+ CUs? | 28W (cTDP 15-54W) |
| Ryzen 5 AI HX 330? | Zen 5 / Zen 5C | 6/12 | TBD | 20 MB / 12 MB L3 | TBD AI TOPs (45 TOPS NPU) | 8 RDNA 3+ CUs? | 28W (cTDP 15-54W) |
The APU is mentioned as the Ryzen AI 9 HX 170 with Radeon 880M iGPU but it should be pointed out that AMD made a very last-minute change and moved to a higher number. We have seen many Strix Point laptops on the Computex show floor that still haven’t been updated with the new Ryzen AI 300 branding and use the older Ryzen AI 100 series numbering.

Coming 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 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, 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 sample. We can expect the final performance to be much higher when the retail silicon ships with up to 5.1 GHz.

Compared to the AMD Ryzen 9 8945HS APU which is the flagship of the Hawk Point lineup, the AMD Ryzen AI 9 HX 370 “Strix Point” APU scored a 7% lead in single-core, 20% lead in multi-core and a massive 40% gain in the graphics test which puts it on par with the RTX 2050 discrete GPU.
The most important thing to keep in mind is that with its new Ryzen AI 300 series, AMD is eliminating a set TDP so there won’t be an HX, HS, H, or U SKU. Instead, manufacturers will have to decide themselves what TDP target they want to use as these chips can scale from 15W and up to 54W so it’s going to be harder to tell what 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 tested at default, then that’s a great gain 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 starting July 2024 through several OEM partners and we can expect better availability starting the holiday 2024 season or Q4.
