Qualcomm Snapdragon X Plus X1P-66-100
The 10-core Snapdragon X Plus variant that adds a 4.0 GHz single-core boost to the 3.4 GHz ceiling of the X1P-64-100, while keeping the same 42 MB of total cache, Adreno X1-85 graphics and 45 TOPS NPU. It is a 4 nm Windows-on-Arm laptop chip with LPDDR5x-8448 memory support up to 64 GB.
Pros
- Single-core boost up to 4.0 GHz, which the X1P-64-100 does not have
- Ten Oryon cores with a 3.4 GHz multi-core maximum
- 45 TOPS Hexagon NPU for Copilot+ PC features
- Adreno X1-85 graphics rated up to 3.8 TFLOPS, against a maximum of 2.1 TFLOPS for the X1-45 in the 8-core Plus chips
- LPDDR5x-8448 memory support up to 64 GB with 135 GB/s of bandwidth
Cons
- The Adreno X1-85 tops out at 1.25 GHz here, below the 1.50 GHz of the X1E-84-100
- Multi-core clock stays at 3.4 GHz, the same as the X1P-64-100: the extra boost applies to single-core loads only
- x86 apps run through emulation on Windows on Arm, so compatibility and speed vary by application
Awaiting benchmarks
No Inno Score yet: single-core and multi-core still need a published benchmark result.
