The ARM Lumex C1-Ultra[1] ("Travis") is a CPU core model from Arm unveiled in 2025.[2] It serves as a successor to the ARM Cortex-X925.[3] It is the first CPU core from Arm (along with its siblings the C1-Premium, the C1-Pro, and the C1-Nano) to support SME2.
Architecture changes in comparison with ARM Cortex-X925
Source:[2]
- Out-of-order window is 25% larger and now handles roughly 2,000 instructions in flight at once; the X925 handles around 1,500.
- There’s a 33% increase in L1 instruction-cache bandwidth, too.
