NVIDIA Olympus uses a 10-wide SMT core to push server single-thread performance
Olympus combines a 10-wide out-of-order core with simultaneous multithreading, taking a different route from Arm’s Cortex X925 to pursue performance per clock. The microarchitecture trade-offs are relevant to engineers evaluating server CPU performance.
- What
- NVIDIA Olympus is a 10-wide out-of-order server core that uses SMT and runs at 3.3 GHz.
- How
- Its large out-of-order structures support strong per-cycle performance; its branch prediction is close to Arm's X925 in the described tests.
- Why it matters
- Olympus shows one route to stronger server single-thread performance without relying on higher clock speeds.
