Nvidia's GB10 cores match Intel and AMD — gaming hinges on x86 emulation

Analysts at Chips and Cheese examined Nvidia’s GB10 “Superchip” and found its Arm-designed Cortex X925 cores—licensed by Nvidia and seen in a Dell Pro Max running GB10—deliver desktop-class performance on par with AMD’s Zen 5 and Intel’s Lion Cove in their fastest desktop implementations.

The GB10 has already appeared in Nvidia’s DGX Spark box, and CEO Jensen Huang has said it forms the basis for the upcoming N1X PC CPU. However, a critical unanswered question is how well those cores will handle x86 code emulation, which remains essential for running most PC games that lack native Arm builds.

Qualcomm’s Snapdragon X CPU includes dedicated hardware to accelerate x86 emulation in its Oryon core, but Arm has not documented any similar x86-acceleration features for the Cortex X925. Windows on Arm’s Prism emulation layer is specifically tuned for Qualcomm hardware, and some reports say N1X’s launch was delayed because a Windows update wasn’t ready.
