Small Wonder: Zotac's HD-ND01 Nettop Review

SiSoft Sandra

Preliminary Testing with SiSoft SANDRA 2009
Synthetic Benchmarks

We began testing with SiSoftware's SANDRA, which stands for System ANalyzer, Diagnostic and Reporting Assistant. For our purposes, it's the memory bandwidth and latency benchmarks that are of interest—an Atom 330 is an Atom 330, as far as mathematical calculation performance is concerned.

The results here were surprising; we didn't expect much of a difference in memory bandwidth given that both chipsets utilize 64-bit single-channel memory configurations. The Zotac makes considerably more efficient use of its 4.2GB/s theoretical maximum bandwidth.

The tables turn, however, when we check access latencies. As expected, both chips have identical latencies for their L1/L2 caches, but the Intel board takes about 10 percent less time to retrieve data from main memory. We'll see whether or not this has a discernible impact on any benchmarks as we continue.
