I just checked the frequency using the xfce4-cpufreq-plugin package, and it looks like the CPU is scaled down to 800 MHz when on battery (the model I selected has a Core i5-3427U CPU @ 1.80 GHz). It hasn't gotten hot or noisy so far. The most demanding thing I regularly do on this laptop is watch HD video though, so it's not under that much strain. But there are definitely no issues with coding or web browsing.
