AMD Ryzen AI 9 HX 375 vs AMD Ryzen 9 270
AMD Ryzen AI 9 HX 375
► remove from comparison
The AMD Ryzen AI 9 HX 375 is a powerful Strix Point family processor that debuted quietly in July 2024. The APU comes equipped with 12 CPU cores running at 2.0 GHz to 5.1 GHz along with the 16 CU RDNA 3.5 Radeon 890M graphics adapter and the 55 TOPS XDNA 2 neural engine. Other noteworthy features include PCIe 4, USB 4 and LPDDR5x-7500 RAM support.
Of the 12 CPU cores, 4 are full Zen 5 cores and 8 are smaller Zen 5c cores. The latter probably run at somewhat lower clock speeds than the former.
This Ryzen AI 9 series APU shares most of the specifications with the Ryzen AI 9 HX 370.
Architecture and Features
Strix Point family APUs are powered by Zen 5 and Zen 5c microarchitecture cores, the latter being a slightly slower, smaller and more power-efficient version of the full Zen 5 core. One of the differences between Zen 5 and Zen 5c is the cache size; Zen 5 cores have larger caches to work with. According to AMD, Zen 5 APUs deliver a 16% IPC improvement over Zen 4-powered APUs thanks to branch prediction improvements and other refinements.
Elsewhere, the HX 375 supports LPDDR5x-7500 and DDR5-5600 RAM, and is also natively compatible with USB 4 (and therefore Thunderbolt). It has PCIe 4.0 support for a throughput of 1.9 GB/s per lane, just like its 8000 series predecessors did. The integrated XDNA 2 NPU is a lot more complex than the original XDNA was for up to 55 INT8 TOPS for accelerating various AI workloads.
Performance
Given the striking similarity in specs, we fully expect the HX 375 to perform about as well as the HX 370 for very decent but certainly not ground-breaking multi-thread performance that's mostly on par with the Core i5-13500HX and the Ryzen 7 7745HX.
Graphics
The Radeon 890M is the most powerful AMD iGPU, as of mid 2024. It features 16 RDNA 3.5 architecture CUs (1024 unified shaders) running at up to 2,900 MHz. Performance-wise, the graphics adapter can be as slow as the Arc 8 or as fast as the RTX 2050 Laptop depending on the benchmark or game. On average, the 890M finds itself very close to the GTX 1650 Laptop making it possible to play 2024 AAA games at 1080p with most settings set to Low.
Naturally, the AMD iGPU is capable of driving four SUHD 4320p60 monitors and it can also efficiently encode and decode the most popular video codecs including first and foremost AVC, HEVC, VP9 and AV1. The latest addition to that list, the VVC codec, is not supported unlike it is with Intel Lunar Lake chips.
Power consumption
The HX 375 is supposed to have a base TDP of 28 W, with laptop makers free to crank it up to up to 54 W if needed. Which they will most likely do to maximize performance.
The TSMC N4P process that the CPU cores are built with make for decent, as of mid 2024, power efficiency.
AMD Ryzen 9 270
► remove from comparison
The Ryzen 9 270 is a rebadged Ryzen 9 8945HS, making it a fast mobile laptop processor. This is an APU of the Hawk Point family that has eight Zen 4 cores running at 4.0 GHz to 5.2 GHz. This APU was introduced at CES 2025 and all of its cores are SMT-enabled for a total of 16 processing threads.
Architecture and Features
Hawk Point family chips are powered by the Zen 4 architecture, much like Phoenix and Dragon Range family chips were. The 16 TOPS NPU present here isn't powerful enough for systems built around the 9 270 to be Copilot+ certified.
Elsewhere, the chip has 16 MB of L3 cache and support for super-fast DDR5-5600 and LPDDR5x-7500 RAM while also being compatible with USB 4 and thus with Thunderbolt. It comes with 20 PCIe 4 lanes, giving fast NVMe SSD up to 7.8 GB/s of throughput.
Please note that this processor is not overclockable and neither is it user-replaceable. It gets soldered to the motherboard for good instead (FP8 socket interface).
Performance
Its CPU performance is slated to be identical to the old Ryzen 9 8945HS and R9 7940HS.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Graphics
The Radeon 780M has 12 CUs (768 shaders) purring away at up to 2,800 MHz. The Radeon will let you use up to 4 monitors with resolutions as high as SUHD 4320p and it will also HW-decode and HW-encode the most widely used video codecs (such as AV1, HEVC and AVC) without breaking a sweat. As for gaming, most 2024 games run fine at 1080p with settings set to Low on this graphics adapter.
Your mileage may vary depending on how high the CPU power limits are, how competent the cooling solution of the system is, how fast the RAM of the system is (there is no dedicated VRAM here).
Power consumption
This Ryzen 9 series chip has a long-term power limit (default TDP) of 35 W to 54 W, giving laptop makers a choice between longer battery life and higher performance. Either way, an active cooling solution is a must for a system powered by this chip.
The R9 270 is built with TSMC's 4 nm process for a reasonably good, as of early 2025, energy efficiency.
