📊 Competitor Analysis▸ Show

The RTX Spark, leveraging its Grace CPU, has shown competitive performance against existing PC chips. In Geekbench 6.5 tests, the Grace CPU in the DGX Spark (which shares the same CPU architecture as RTX Spark) scored approximately 3120 points in single-thread performance and 18,895 in multi-thread performance. This slightly surpasses the AMD "Strix Halo" Ryzen AI 395 chip, which achieved around 2883 single-thread and 17,442 multi-thread scores in similar comparisons. While specific pricing for the RTX Spark in consumer PCs is not yet available, the underlying GB10 chip (used in DGX Spark) was priced at $3999 at its launch. Nvidia's move is expected to intensify competition with Intel and AMD in the x86-dominated CPU market, and with Apple and Qualcomm in the ARM-based PC chip space.
