Low-Power Processors: When Performance Matters--VIA Nano X2 compared to Intel Atom
This white paper takes a fresh look at the performance of low-power x86 CPUs, now that VIA has introduced dual-core and quad-core CPUs. Since many benchmarks are multi-threaded, Intel Atom processors benefit from dual-core and hyper-threading to compete with VIA’s performance-oriented Nano architecture. However, a technical comparison of Nano and Atom microarchitectures shows that the VIA Nano is designed for higher performance (50% more instructions/clock on each thread). For multiple threads, the VIA Nano X2 and Quadcore should outperform Atom-based dual-core CPUs. This white paper presents testing results that confirm Nano’s raw performance advantage over the fastest Atom CPUs.
