AMD Ryzen 7 7840S vs AMD Ryzen 7 H 260 vs AMD Ryzen 9 270
AMD Ryzen 7 7840S
► remove from comparison
The AMD Ryzen 7 7840S is a fast high-end laptop processor of the Phoenix series. It offers 8 cores (octa core) based on the Zen 4 architecture that supports hyperthreading (16 threads). The cores clock from 3.8 (base) up to 5.1 GHz (single core boost). The processor includes 8 MB L2 cache and 16 MB L3 cache. The processor is exclusively available in Lenovo laptops but the specs are similar to the regular Ryzen 7 7840HS.
The performance of the R7 7840S is only slightly below the fastest model, the R9 7940HS, as the clock speed difference is only minimal (e.g. -100 MHz / 2% slower single core boost). Therefore, the CPU should also perform slightly higher than the old top model Ryzen 9 6980HX (8 Zen 3 cores with up to 4.9 GHz) at 54W TDP and Ryzen 9 6980HS at 35W TDP. Compared to the higher end Dragon Range series, the 7840HS should be similar to the Ryzen 7 7745HX (also 8 Zen 4 cores, max 5.1 GHz, 55W TDP, 32 MB L3).
The chip integrates a modern and fasts RDNA 3 graphics card (iGPU) called Radeon 780M with 12 CUs and up to 2.7 GHz clock speed. Furthermore, the Phoenix series include a video engine with AV1 de- and encoding, a new Xilinx FPGA based XDNA AI accelerator (Ryzen AI) that should be faster than the AI engine in the Apple M2 SOC and a dual-channel DDR5-5600 / LPDDR5x-7500 memory controller (with ECC support). The connectivity features includes 2 possible USB 4 (40 Gbps) ports and 20 PCIe 4.0 lanes for a GPU and SSDs.
The Phoenix series uses a single monolithic design (unlike the chiplet design of the 7045HX series) and is manufactured in the modern 4nm process at TSMC. The TDP can be configured between 35 and 45 Watt.
AMD Ryzen 7 H 260
► remove from comparison
The AMD Ryzen 7 H 260 is a high-end notebook processor from the Hawk Point series with 8 cores and hyperthreading (SMT), which means it can process up to 16 threads simultaneously. At release, the CPU is only available in China and is technically practically identical to the older AMD Ryzen 7 8845HS or Ryzen 7 7840HS (slower AI engine).
The performance of the second-fastest model in the Hawk Point series should only be slightly behind the Ryzen 9 7940HS (+100 - 200 MHz clock, e.g. only 2% slower Turbo). As a result, the performance at 54W TDP should also be comparable to the AMD Ryzen 7 7745HX (also 8 Zen 4 cores, max 5.1 GHz, 55W, 32 MB L3) and thus clearly ahead of the old top model AMD Ryzen 9 6980HX resp. 6980HS (with lower TDP).
The chip integrates a modern RDNA 3-based graphics card (iGPU) called Radeon 780M with 12 CUs and up to 2.7GHz including AV1 video engine. Furthermore, a Xilinx FPGA-based XDNA AI accelerator is also integrated, which is now clocked higher. Hawk Point offers 2x USB 4 (40 Gbps), 20 PCIe 4.0 lanes and a dual-channel DDR5-5600 / LPDDR5x-7500 memory controller (with ECC support).
The Hawk Point series is a single chip (unlike the Dragon Range 7045HX series) and is manufactured at TSMC using the modern 4nm FinFET process.
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.
