AMD Ryzen 9 H 270 vs AMD Ryzen 9 PRO 6950H vs AMD Ryzen 7 8745HS

AMD Ryzen 9 H 270

The Ryzen 9 H 270 is a rebadged Ryzen 9 270 (or Ryzen 9 8945HS) for China, 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 H 270 is built with TSMC's 4 nm process for a reasonably good, as of early 2025, energy efficiency.

AMD Ryzen 9 PRO 6950H

The AMD Ryzen 9 PRO 6950H is a processor for big (workstation) laptops based on the Rembrandt generation. The R9 6900HX integrates all eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.9 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 6 nm TSMC process. The 6950H is the professional version of the consumer R9 6900HX without overclocking features but with additional management features and the Microsoft Pluton Security processor.

The new Zen 3+ architecture is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip itself however, offers a lot of new features, like support for USB 4 (40 Gbps), PCI-E Gen 4, DDR5-4800MT/s or LPDDR5-6400MT/s, WiFi 6E, Bluetooth LE 5.2, DisplayPort 2, and AV1 decode.

A big novelty is the integrated GPU Radeon 680M, that is now based on the RDNA2 architecture and offers 12 CUs at up to 2.4 GHz. It should be the fastest iGPU of all at the time of announcement.

Performance

While we have not tested a single system built around the 6950H as of August 2023, we have tested one system featuring the 6950HS, its slightly more power-efficient brother. Based on that, expect the 6950H to be slightly faster than the Ryzen 7 5800H, Ryzen 9 4900H, Ryzen 5 PRO 7640HS and also the Core i7-11800H. In other words, this is a higher-end chip that will handle almost any task with ease, as of late 2022.

Your mileage may vary depending on how competent the cooling solution of your laptop is and how high the CPU power limits are.

Power consumption

This Ryzen has a default TDP of 45 W (also known as the PL1). A high-performance cooling solution is a must for a CPU like this one here.

Ryzen 9 PRO 6950H is built with TSMC's 6 nm process leading to great, as of late 2022, energy efficiency.

AMD Ryzen 7 8745HS

The Ryzen 7 8745HS is a China-only Hawk Point family chip that never received an official launch. Targeted at gaming and productivity laptops but widely used in mini-PCs, too, the 8745HS features 8 cores (16 threads thanks to SMT support) running at up to 4.9 GHz, along with the still fairly capable Radeon 780M iGPU. There is no NPU here.

As an APU meant for use within China, this Ryzen 7 should be fully compliant with the Chinese government-approved cryptography standards.

The only difference between the 8745HS and the 8745H is the slightly lower default wattage of the latter, potentially leading to slightly lower clock speeds.

Performance

We fully expect this Zen 4 architecture processor to be about as fast as the Ryzen 7 7745HX (8 Zen 4 cores, 3.6 GHz to 5.1 GHz) meaning its multi-thread performance is a little better than the Core Ultra 9 185H but a few percentage points behind the Ryzen AI 9 HX 370.

Architecture and Features

Unlike Zen 3, Zen 4 features AVX512 support along with other improvements, like larger caches/registers/buffers across the board. Elsewhere, the 8745HS has 16 MB of L3 cache and a fast RAM controller (up to LPDDR5x-7500 and up to DDR5-5600). There are 20 PCI-Express 4 lanes for connecting devices such as NVMe SSDs (1.97 GB/s per lane) and graphics cards; USB 4 / Thunderbolt support is onboard, too. Please note that the APU isn't overclockable and neither is it user-replaceable. It gets soldered on to the motherboard for good (FP7r2 or FP8 socket interfaces).

Graphics

The Radeon 780M (12 CUs / 768 shaders, up to 2,600 MHz) can drive 4 monitors simultaneously with resolutions as high as SUHD 4320p. It will also have little issue hardware-encoding and hardware-decoding the most widely used video codecs (AV1, AVC, HEVC). As far as gaming is concerned, many titles are still playable at 1080p as of early 2025 albeit with most settings dialed down do Lowest or Low.

Power consumption

This Ryzen 7 series chip has a long-term power limit (default TDP) of 35 W to 54 W, giving system makers a choice between improving battery life and making the system they're designing faster. Either way, an active cooling solution is a must for a laptop or a mini-PC built around this APU.
