CompuLab Trim-Slice: Dual-Core ARM Tegra 2 Desktop

When starting off with the Apache web-server benchmark, the Trim-Slice performance is rather poor as it's running at about a third the speed of the PandaBoard ES. Yet the PandaBoard ES is just using a 16GB SDHC card as its storage medium and the Trim-Slice is using a SATA HDD. The PandaBoard ES runs up to 1.2GHz for its dual-core ARM Cortex-A9 where as the Trim-Slice is up to 1.0GHz. This difference may come down to the slightly different software stack between the two ARM devices.

The Dhrystone 2 performance for the Trim-Slice as measured by the BYTE Unix Benchmark was faster than the PandaBoard ES, but again the PandaBoard ES isn't going to be in an optimal state under Ubuntu Linux until the 12.04 release as the best hardware support for this OMAP4660 platform is in the Linux 3.1+ kernel.

The Tegra 2 Trim-Slice came out ahead of the PandaBoard ES and Atom (N270 and Z530) systems with CacheBench. It will be interesting to see how the PandaBoard ES and Trim-Slice compare when both are running Ubuntu 12.04 snapshots.
