Why Tegra 3 OC isn't needed

  Sorry viewers :( I abandoned my blog after less than 6 months of usage however, I haven't realized the important message the blog has had and it's own importance to me in spreading the word about things that some may say meh it doesn't matter or things like WOW that simply rocks.

      So, many devices like HTC's previous flagship the ONE X (Endeavor) or Google's own Nexus 7 feature the Tegra 3 chipset and I feel that it simply doesn't need to be overclocked. For example, we can overclock the Nexus 7 up to 1.7GHZ yet, to see our benchmark scores go up a few FPS or shave .001 of a second from app launches but honestly I feel it's just not needed for a Quad core CPU and 12 GPU to be overclocked due to many risk that not only affect warranty (Thanks HTC) and long term usage.
   
       Many devices with Tegra 3 are throttled when heat levels exceed a certain temperature and the device begins throttling it's self to maybe 800 MHZ and/or taking some CPU cores offline to protect from heat damage. There is a solution to this called undervolting, however undervolting can cause long term usage problems and short terms problems that can be fixed with a simple battery pull. For example my old Samsung Captivate when it's undervolted when running @ 800 MHZ it simply crashes but a much higher frequency 1.5 GHZ uses when undervolted has to use less power due to what I believe is caused by the die on the CPU meaning that my phone will crash when undervolting @800MHZ but not at 1.5GHZ no matter how high or low my MV is.
