AMD Ryzen 7 H 260 vs AMD Ryzen 9 7945HX
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 7945HX
► remove from comparison
The AMD Ryzen 9 7945HX is a fast high-end laptop processor of the Dragon Range series. It offers 16 cores based on the Zen 4 architecture that supports hyperthreading (32 threads). The cores clock from 2.5 (base) up to 5.4 GHz (single core boost). The 7945HX is the fastest mobile Ryzen CPU at launch and derived from the desktop Ryzen 9 7950X.
The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible cores) in 5nm and an IO-die (including the memory controller and the Radeon 610M iGPU) in 6nm. The chip integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB4), 28 PCIe 5.0 lanes (for GPU and SSDs) and a dual-channel DDR5-5200 memory controller.
Performance
The Ryzen 9 7945HX is among the fastest processors in our database, as of August 2023. It is in the same league as the Ryzen 9 7945HX3D and noticeably ahead of the Core i9-13980HX, as far as multi-thread benchmark scores are concerned. It is outrageously, unbelievably fast, and those fortunate enough to purchase a laptop built around this CPU will have no performance issues for at least three years.
Thanks to its powerful cooling solution and a long-term CPU power limit of 128 W, the ROG Strix Scar 17 G733PY-XS96 is one of the fastest laptops built around the 7945HX that we know of.
The R9 7945HX is rated at a TDP of 55 Watt and can be configured up to 75 Watt (cTDP).
