The first AMD Ryzen AI 9 HX 370 “Strix Point” APU benchmarks have leaked and show 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 over previous flagship, Ryzen 9 8945HS
It didn’t take that long, the first unofficial benchmarks of AMD’s upcoming Ryzen AI 300 APUs started to leak and they are very impressive in their first preview. 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 go down the AI ​​branding route in the future and we might see better. naming schemes in the future, hopefully. 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, 24-thread chip that includes a configuration of four Zen 5 and eight Zen 5C. This chip runs at up to 5.1 GHz, offers 36 MB cache (24 MB L3 + 12 MB L2) and a Radeon 890M iGPU with 16 compute units or 1024 cores. So over the previous flagship, the Ryzen 9 8945HS, you’re getting 50% more cores/threads, 33.3% more compute units, and 3.12x more NPU performance, which is a great boost between gens.
As for the Geekbench leak, it looks like we’re looking at an early sample given that while it matches the base clock of 2.0GHz, the log file shows a boost of around 4.2GHz, which is below the peak clock frequency of 5 ,1 GHz. .
AMD Ryzen AI “HX” APUs:
| The name of the CPU | Architecture | Cores / Threads | Clock Speeds (Max) | Cache (Total) | AI capabilities | iGPU | TDP |
|---|---|---|---|---|---|---|---|
| Ryzen 9 AI HX 370 | Zen 5 / Zen 5C | 24. 12 | 2.0 / 5.1 GHz | 36 MB / 24 MB L3 | 77 TOP AIs (45 TOP NPUs) | 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 TOP (45 TOP 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 TOP (45 TOP NPU) | 12 RDNA 3+ CU? | 28W (cTDP 15-54W) |
| Ryzen 5 AI HX 330? | Zen 5 / Zen 5C | 6/12 | TBD | 20 MB / 12 MB L3 | TBD AI TOP (45 TOP NPU) | 8 RDNA 3+ CU? | 28W (cTDP 15-54W) |
The APU is mentioned as a Ryzen AI 9 HX 170 with a Radeon 880M iGPU, but it should be pointed out that AMD made a very recent change and moved to a higher number. On the Computex show floor, we saw many Strix Point laptops still not updated with the new Ryzen AI 300 branding and using the older Ryzen AI 100 series numbering.

In terms of numbers, the AMD Ryzen 9 AI HX 370 APU was tested in the Geekbench 5, Geekbench 6 and OpenCL benchmarks. In Geekbench 5.4.5, the chip scored 1,847 points in single-core and 14,316 points in multi-core tests. In the Geekbench 6.3.0 benchmark, the chip scored 2,544 points in single-core and 14,158 points in multi-core tests. Finally, in the OpenCL test, the iGPU RDNA 3.5 (Radeon 890M) scored 41,995 points.
The CPU performance of the Zen 5 cores on the Strix Point APU looks great despite being an early sample. We can expect the final performance to be much higher when the retail silicon ships at up to 5.1 GHz.

Compared to Hawk Point’s flagship AMD Ryzen 9 8945HS APU, the AMD Ryzen AI 9 HX 370 “Strix Point” APU scored a 7% gain in single-core, a 20% gain in multi-core, and a massive 40% gain in the graphics test, which putting 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 removing the set TDP, so there will be no HX, HS, H or U SKUs. Instead, manufacturers will have to decide for themselves what target TDP they want to use, as these chips can scale from 15W all the way up to 54W, making it harder to tell what actual TDP this benchmark has achieved. The default TDP is 28W while the AMD Ryzen 9 8945HS has a default TDP of 45W. So if tested at default settings then this is a great gain but if tested at a lower TDP say 15-20W then this result is still more impressive.
AMD Ryzen AI 300 processors will be available from July 2024 through several OEM partners, and we can expect better availability from holiday 2024 or from the fourth quarter.
