- The RTX Spark is NVIDIA's consumer chip designed for Windows laptops and small desktops, announced in 2026, and not a direct competitor to Apple's M-series due to differing strengths.
- CPU performance of the Spark is two generations behind Apple, with single-thread scores 22% behind M4 and 37% behind M5, and multi-core similar to M3 Max/M4 Pro.
- Spark's idle power is significantly higher than Apple's (mid-20s watts vs. 1-2 watts), making efficiency a weak point, while memory bandwidth is about half that of M5 Max.
- In AI performance, Spark excels at prefill (compute-bound) with speeds up to 2000 t/s, but lags in decode (memory-bound) at 38-59 t/s, where Apple shines.
- Spark is built on TSMC 3nm, a node behind Apple's expected N2 for M6, and pricing is at parity with M5 Max at 128GB, with Apple benefiting from locked memory contracts during shortages.
- The Spark targets CUDA developers and workstation users, running Windows/Linux, and is compared to small CUDA workstations or Strix Halo, not Apple Silicon.
- Future NVIDIA developments like the Vera Rubin stack with LPDDR6 may address bandwidth limitations and improve competitiveness.
