AMD Ryzen 9 7945HX3D
The AMD Ryzen 9 7945HX3D is a Dragon Range laptop processor with 16 Zen 4 cores, 32 threads and 128 MB of L3 cache using AMD 3D V-Cache. It runs at 2.3 GHz base and up to 5.4 GHz boost with a 55 W default TDP (55-75 W configurable), supports DDR5-5200 and has a basic Radeon 610M iGPU. It powers the ASUS ROG Strix SCAR 17 X3D.
Pros
- 16 Zen 4 cores and 32 threads, 2.3 GHz base and up to 5.4 GHz boost
- 128 MB of L3 cache with AMD 3D V-Cache technology
- 28 PCIe 5.0 lanes and DDR5-5200 SO-DIMM support
- Supports AMD EXPO memory profiles, Precision Boost Overdrive and Curve Optimizer
- In review testing it scored 2916 single-core and 16957 multi-core in Geekbench 6, and 1935 / 32782 in Cinebench R23
Cons
- Radeon 610M iGPU has only 2 graphics cores, so a discrete GPU is needed for gaming and 3D work
- Default TDP is 55 W (55-75 W configurable), but the reviewed laptop ran it at up to 115 W (100 W sustained), so it suits large, well-cooled chassis
- AMD lists no NPU for this chip, and memory tops out at 64 GB of DDR5-5200 SO-DIMM
