Can't name any brands but based on the gaming laptop comparison reviews I've read you can't trust the numbers. First, a well known fact is that the laptop GPU's aren't as powerful as their desktop counterparts. Second, and this is the biggest issue, without proper testing it's impossible to tell which laptop performs best even if all the components are similar. Some may start strong but after a while of tough action they slow down to a crawl due to inefficient cooling. Some may seem slower but maintain their speed for hours. Even physical size doesn't directly tell about the efficiency of cooling.A laptop with a weaker CPU can outperform many equipped with a more powerful one. The reason may be in better airflow or potentially also well optimized bios settings.
