For reference, this is just a single benchmark, but as an idea of each vendor's top mobile CPU single-threaded performance:

Geekbench Single Thread Score:

- DGX Spark (same CPU as RTX Spark): 3125

- Snapdragon X1 Elite: 2950

- Snapdragon X2 Elite Extreme: 4050

- AMD Ryzen 9 9955HX: 3225

- Intel Core Ultra 9 290HX Plus: 3175

- Apple M5 Max: 4350

I'm happy to be wrong about Qualcomm's latest X2 chip performance, even if it is shipping in only a single product so far. Their previous best was the lowest in this list.
