Microsoft reveals new Mac Studio rival with Nvidia RTX Spark and 128 GB RAM

Yesterday, Microsoft joined multiple manufacturers in embracing Nvidia's nascent RTX Spark chipset. As we discussed separately, the Surface Laptop Ultra combines the RTX Spark with a 2,000-nit Mini LED display in a design that is already being compared with the MacBook Pro 16 we reviewed earlier this year (curr. $2,529 on Amazon).

However, Microsoft is not done with Nvidia's RTX Spark chipset just yet. Instead, it has now presented the Surface RTX Spark Dev Box during its Microsoft Build 2026 opening keynote as a new Mac Studio rival. While the Dev Box utilises the same RTX Spark chipset as the Surface Laptop Ultra, the former can push the latter's 20 ARM CPU and 6,144 Blackwell CUDA cores to 100 W. Also, Microsoft has included the following ports within its new mini-PC:

• 1x 3.5 mm jack
• 1x Ethernet
• 1x HDMI
• 2x USB Type-A
• 2x USB Type-C

Moreover, Microsoft plans to offer the Surface RTX Spark Dev Box with 128 GB of unified memory encased in an aluminium body. The Surface RTX Spark Dev Box should be available in 2026 through Microsoft's online store. Pricing remains unknown for now, though. Incidentally, Microsoft has been here before with the short-lived Windows Dev Kit 2023.
