The AMD Ryzen 9 7945HX is a quick excessive-finish laptop computer processor of the Dragon Range sequence. It presents 16 cores primarily based on the Zen 4 structure that helps hyperthreading (32 threads). The cores clock from 2.5 (base) as much as 5.4 GHz (single core increase). The 7945HX is the quickest cellular Ryzen CPU at launch and derived from the desktop Ryzen 9 7950X.
The efficiency of the R9 7945HX needs to be much like a Core i9-13900HX (Raptor Lake, 24 Hybrid cores, 5.4 GHz max) within the excessive finish phase of cellular CPUs for gaming laptops. AMD marketed the R9 7945HX as considerably sooner than the outdated Ryzen 9 6900HX (8 Zen 3 cores, 4.9 GHz max) which is sensible because of the increased core depend, clock velocity and improved structure.
The Dragon Range sequence nonetheless makes use of a chiplet design with two CCD-clusters (every with 8 potential cores) in 5nm and an IO-die (together with the reminiscence 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 twin-channel DDR5-5200 reminiscence controller.
The R9 7945HX is rated at a TDP of 55 Watt and may be configured as much as 75 Watt (cTDP).
