First benchmarks of AMD’s Ryzen AI 9 HX 370 “Strix Point” APU have leaked, and with Zen 5 and RDNA 3.5 cores, it shows some big boosts in both CPU and GPU performance.
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 previous flagship Ryzen 9 8945HS
It didn’t take long for the first unofficial benchmarks of AMD’s upcoming Ryzen AI 300 APUs to leak out, and they’re pretty impressive in their first showcase. The chip in question is the Ryzen AI 9 HX 370, which is a huge and confusing name for some, but we’ll have to get used to it, as both Intel and AMD are going the AI branding route in the future and we can see better. 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, 24-thread chip with four Zen 5 and eight Zen 5C configurations. This chip runs at overclocks of up to 5.1GHz, offers 36MB of cache (24MB L3 + 12MB L2) and 16 compute units or a 1024-core Radeon 890M iGPU. So compared to the previous flagship Ryzen 9 8945HS, you get 50% more cores/threads, 33.3% more compute units and 3.12x NPU performance, which is a huge gain over the gen.
As for the Geekbench leak, we’re looking at an early sample, given that the log file shows a clock speed of around 4.2 GHz, which is lower than the top-rated clock speed of 5.1 GHz, although that corresponds to a base clock of 2.0 GHz. .
AMD Ryzen AI “HX” APUs:
| CPU Name | Architecture | Cores / Themes | 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 TOP (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 TOP (45 TOPS 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 TOPS NPU) | 8 RDNA 3+ CU? | 28W (cTDP 15-54W) |
The APU is mentioned as Ryzen AI 9 HX 170 with Radeon 880M iGPU, but it’s worth noting that AMD made a very last minute change and went to a higher number. On the Computex show floor, we saw many Strix Point notebooks that still hadn’t been updated with the new Ryzen AI 300 branding and were still using the old Ryzen AI 100 series numbering.

As for the numbers, AMD Ryzen 9 AI HX 370 APU was tested in Geekbench 5, Geekbench 6 and OpenCL tests. The chip scored in Geekbench 5.4.5 1847 points in single-core tests and 14,316 points in multi-core tests. In the Geekbench 6.3.0 benchmark, the chip scored 2544 points in single-core tests and 14,158 points in multi-core tests. Finally, the RDNA 3.5 (Radeon 890M) iGPU scored in the OpenCL test 41,995 points.
The CPU performance of the Zen 5 cores on the Strix Point APU looks great despite being an early sample. When the retail silicon ships up to 5.1 GHz, we can expect the final performance to be even higher.

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 has a 7% gain in single-core, a 20% lead in multi-core, and a 40% gain in the massive Graphics test, putting it on par with the RTX 2050 discrete GPU.
The most important thing to remember is that with the new Ryzen AI 300 series, AMD is doing away with the fixed TDP so there will be no HX, HS, H or U SKUs. Instead, manufacturers will have to decide for themselves what TDP target they want to use, as these chips can scale between 15W and 54W, so it’s hard to say what actual TDP this benchmark works at. The standard TDP is 28W, while the AMD Ryzen 9 8945HS has a standard TDP of 45W. So, if tested at default, this is a big gain, but if tested at a lower TDP, 15-20W, this 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 starting from the 2024 season or Q4.
