Our testing methods
Over the next few pages, you'll see the Zacate test build compared to two full-sized Optimus notebooks, the Asus N82Jv and 833Jc; three consumer ultraportables, the Acer Aspire 1810TZ, Acer Aspire 1830TZ, and Toshiba Satellite T235D; one netbook, the Eee PC 1015PN; and one Consumer Ultra-Low-Voltage nettop, the Zotac Zbox HD-ND22.

The 1015PN, N82Jv, U33Jc, and T235D were all tested twice: once plugged in and once unplugged using included "battery-saving" profiles. In the case of the 1015PN, N82Jv, and U33Jc, we compared the battery-saving results to those obtained using built-in "high-performance" modes. The N82Jv's battery-saving results were obtained with Asus' Super Hybrid Engine enabled, as well, which dropped the CPU clock speed from 2.4GHz to 0.9-1GHz depending on load. On the U33Jc, the high-performance profile included by Asus raised the maximum CPU clock speed from 2.4 to 2.57GHz. On the Eee PC 1015PN, the included Super Hybrid Engine "Super Performance Mode" raised the CPU speed by 25MHz, while the "Power Saving Mode" limited the CPU to about 1GHz and disabled the Nvidia GPU.

All tests were run at least three times, and we reported the median of those runs.

I should note that, in my hurry, I seem to have misplaced the version numbers for the Zacate system's graphics and audio drivers. Apologies for that. Also, for what it's worth, CPU-Z wouldn't report memory timings.
