AMD Ryzen 7 9700X vs AMD Ryzen 7 8745HS vs AMD Ryzen 9 270

AMD Ryzen 7 9700X

The AMD Ryzen 7 9700X is an upper mid-range desktop CPU of the Granite Ridge product family that sports 8 Zen 5 cores (16 threads) running at 3.8 GHz to 5.5 GHz, along with PCIe 5 support and a basic RDNA 2 architecture iGPU. The Ryzen was launched in June 2024, with sales slated to start some time in August.

Architecture and Features

Like Strix Point APUs, Granite Ridge processors make use of the new Zen 5 microarchitecture. However, there are no efficient cores here; all of 9700X's cores are full Zen 5 cores with a "proper" Zen 5 implementation, not the simplified mobile version that has a lower AVX-512 performance. 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, desktop Zen 5 delivers a 16% IPC uplift over Zen 4 thanks to branch prediction improvements and other refinements.

Elsewhere, the 9700X has 32 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 9700X is unlocked for overclocking. Naturally, the AM5 socket CPU fully supports Windows 11, 64-bit Windows 10 as well as many Linux distros.

Performance

In our review, the Ryzen 7 delivered multi-thread benchmark scores very close to those of the Ryzen AI 9 HX 370 and 375, as well as the Core i7-12700 and i7-12700K.

Graphics

The Radeon 610M comes equipped with just 128 unified shaders running at up to 2,200 MHz. While this certainly isn't a gaming GPU, it's fast enough to run some competitive titles such as Counter-Strike 2 (~50 fps at 1080p / Low) as well as older (pre-2019) titles.

It can HW-decode many popular video codecs including first and foremost AVC, HEVC, VP9, AV1.

Power consumption

The CPU cores are built with TSMC's N4P process for a good, as of mid 2024, power efficiency. (Apple is the leader in this regard with the second-generation 3 nm process.)

The Ryzen 7's long-term TDP is either 65 W or 105 W, with each user free to make their own choice. If overclocked, its power consumption figures will increase significantly.

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.

AMD Ryzen 9 270

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.
