TouchPad Overclocking Benchmarks: Which Kernel is the fastest? 28

by Tim Stiffler-Dean Thu, 01 Sep 2011 5:10 pm EDT

For some users, overclocking on webOS devices has always had some bit of mystery to it. It is easily understood that overclocking mostly allows for a more stable and faster experience on the TouchPad, but then why is there a need for so many different kernels when they all basically serve the same purpose?

The simple answer is that they do not all serve the same purpose. New kernels are not built by the WebOS Internals team (specifically uNiXpSyChO) just to push the processor to faster speeds; they serve a far better purpose than just that. We won't get into all of the details here about how the different Kernels work, but if you take a look at the conversations in our forums about each of these kernels, you should be able to get a good view of what they all have to offer.

That said, the number one reason, by far, that users install new kernels is to overclock their processors to faster speeds (thus giving themselves a better device experience). With current devices you can install the well-known UberKernel using Preware and bring your processor speeds on the TouchPad up from the default 1.2 Ghz, all of the way to 1.5 Ghz and beyond. Some experimental Kernels go even faster than that, overclocking devices up to 1.9 Ghz in both cores. That is insane.

The question that remains, of course, is which kernels perform best at each individual level? If you test five kernels all at the same processor speed, which one will run more optimally? Also, if each Kernel was set at its highest overclocked speed, would there be enough noticeable difference in the benchmarks to justify using one over the other?

Using nBench and webOSmark to get his testing results, PreCentral member ghostinator has been thoroughly testing each of the Kernels to see how they react under different settings. He's published his results in the forums with charts to make it easier to follow along, and even provides the settings that he uses to keep his device running at its best. By looking at his charts, it's pretty obvious that overclocking your device, no matter which Kernel you install, is going to improve performance.

If you want to see his other charts and try your hand at testing these kernels yourself, head to the forums through the source link below to join the thread that ghostinator has started to see the activity that's already going on. This isn't just good for the practical use of seeing which Kernel will work best at different levels, but it's a great learning tool as well (overclocking newbies should check this thread out - you'll learn a lot).


It would be interesting to see the effects on power consumption with each of these kernels. Do some manage power more efficiently than others?

I never overclocked but i'm looking to try out UberKernal, has anyone had issues with it? I only have one Touchpad so I don't want to brick it and want to know what the odds are of it working flawlessly.

webOS devices almost don't brick.

I took the plunge and installed the UberKernel. Overclocking to 1.5

I have not noticed any considerable change in battery life.

it is quite a bit faster IMO.

+1 Same here. I only charge once every two or three days, overclocked to 1.5.

Uberkernel's role has always been as the stable kernel. If you want safety & reliability, go with Uberkernel.

I'm "overclocking" both my Pre(-) (up to 720 Mhz) and my TouchPad using 'Uber-Kernel' (up to 1.5 Ghz). Performance is MUCH better with the Pre(-), and somewhat better with the TouchPad.

I haven't gone up on either of those, cause I like my CPUs working in the condition that they are in, not melted (otherwise, I'd push further).

PS: Still on original Pre(-) since 29 March 2010.

Been "overclocking" with 'Uber-Kernel' since about April 2010.

Thanks WebOS Internals!

uberkernel is what I have since I bought my tp yesterday. I could not tell the difference in battery life since I installed it within the hour of buying it.

using F4, at 1.8GHZ. BIG improvement over 1.5.

but is the battery life stable? I've tried some of the other kernels, specifically F15-C, and my battery life was markedly worse than Uberkernel.

I'll give UberKernel a go. My TouchPad is two days old now. Reading the comments has removed my anxiety to test overclocking, thanks!

I would also like to know what impact the faster kernels have on battery life. I have had my TP since August 2nd and have had it overclocked with Uberkernel for at least one month. I have not noticed much difference other than the OS running a bit snappier. Since HP's big announcement, I've been increasingly curious about overclocking to 1.7GHz but have refrained because of concerns over battery life at higher speeds.

I installed warthog... So far so good.. F4 runs both cores pretty much at the same time. My thoughts = more power consumption. Warthog uses the 2nd CPU less frequently/when needed. Just check out the graph on govnah. Easy to overclock just follow directions!

I'm running uberkernal @ 1.5, it's working great. Where do you get the other kernels? I don't see them in Preware.

Have to add the "experimental kernels" feed to 'Preware'. Be sure to not include my "quote" marks. It does have warnings. I am not to be held liable for damage, nor is anyone else. Just a friendly warning.

The Wiki Page:

Thanks! Uberkernal made a big improvement already. Boot-up took less than 1/2 the time, and viewing .pdf files is much more pleasant! The whole experience just seems more responsive & quicker. I'll stick with 1.5 for a few days then try one of the experimentals.

uberkernal = Placebo!



Do you have a touchpad?

I noticed a HUGE difference with uberkernel and using govnah to 1.5. The big test was rendering a 350 mb PDF with lots of images. It was a book that would cause the adobe reader to choke on every single page. The delay is now gone when flipping between pages.

Anyone ever hear of error bars or confidence intervals; benchmark charts without them are useless!

Do we have to leave the govnah application running?



You should read the following article from webOSFrance which gives great informations on overclocking VS Battery life:

Sorry if this is a stupid question, but how safe is it to overclock my Touchpad? I remember when people started talking about overclocking that there was some serious warnings against it, and everyone said that it was not for the faint of heart. I get the impression that that has changed since, but the last thing I would want to do would be to brick my beloved Touchpad. I may know my way around a computer, but I am far from a programer, what advice can you give me? shows you Step by Step with screenshots for each single step how to overclock, not only that, but also shows you other tricks to boost up your TouchPad. Overclock is just half of the solution. When I set the overclock with warthog kernel the WiFi keeps lost connection and I need to reboot the Touchpad before able to search the WiFi connection. No problem at all with the 1.5 MHz overclock so far and I think it is faster than my old iPad 1. The screen is very sensitive and better than many of the other Android powered tablet.

I installed F15Ckernel and Touchpad did run at 1.7 or so, but it did cause problems. It would lock up or it would not turn off. I removed and have installed the Uberkernel at 1.5GHz.
