AMD Ryzen 9 9950X vs AMD Ryzen 9 H 270
AMD Ryzen 9 9950X
► remove from comparison
The Ryzen 9 9950X is a very, very powerful desktop CPU of the Granite Ridge product family that features 16 Zen 5 cores (32 threads), PCIe 5 support and a basic iGPU. The Ryzen was launched in June 2024, with sales slated to start in August.
The 9950X shares some of the specifications with the mighty Zen 4-powered Ryzen 9 7950X, including (but not limited to) the 16 MB L2 cache, the 64 MB L3 cache, the 5.7 GHz top clock speed and the 170 W long-term TDP.
Architecture and Features
Just like Strix Point APUs, Granite Ridge processors make use of the new Zen 5 microarchitecture. However, there are no efficient cores here; all of 9950X's cores are full Zen 5 cores. Furthermore, Granite Ridge is a multi-die design with only the CPU cores produced using a fairly modern 4 nm TSMC process. Strix Point processors are a single-die design, from what we know.
According to AMD, Zen 5 delivers a 16% IPC improvement over Zen 4 thanks to branch prediction improvements and other refinements.
Elsewhere, the 9950X has an impressive 64 MB of L3 cache and 24 direct PCIe 5 lanes (3.93 GB/s throughput per lane) with up to 12 additional PCIe 4 lanes available depending on the motherboard. It supports DDR5 RAM as fast as 5,600 MT/s (up to 8,000 MT/s if overclocked).
The 9950X is unlocked for overclocking. Naturally, the AM5 socket CPU supports Windows 11, 64-bit Windows 10 as well as many Linux distros.
Performance
According to early July leaks, its multi-thread performance is about as good as that of the 24-core Core i9-14900K Intel CPU. We'll definitely update this section once we get our hands on a system powered by the 9950X.
Graphics
The Radeon 610M comes equipped with just 128 unified shaders running at up to 2,200 MHz. Its gaming performance is slated to be extremely low and only just sufficient for pre-2020 games in resolutions such as 1024x768.
Power consumption
The CPU cores are built with TSMC's N4P process for good, as of mid 2024, power efficiency. (Apple is the leader in this regard with the second-generation 3 nm process.)
The Ryzen 9's long-term TDP is 170 W. It'll probably consume up to 250 W when under heavy short-term loads. If overclocked, the power consumption figures will increase significantly.
AMD Ryzen 9 H 270
► remove from comparison
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.
