But, the arm processor is 1.8 per processor and its a quad core. So if I add it together, probably it would be additional 50% faster. and considering what you said, extremely lightweight by comparison, I am not sure how many more time lightweight, but I assume it would be like ten times at least if not a lot more... Also it would be good for long term use, where as the libreboot is probably not gonna last that long. Everyone who replied to me probably knows this and more probably already. But good luck reverse engineering that. :) it will be well worth it if you succeed. > > > ___ > arm-netbook mailing list arm-netbook@lists.phcomp.co.uk > http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook > Send large attachments to arm-netb...@files.phcomp.co.uk ___ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk

They got this low simply from node shrinks, I think we're talking about different things: the X200 is a laptop from a several years ago, so it's unaffected by Intel's current performance: the kinds of processors it can take has been frozen for many years already (and they're much more power hungry than the RK3288, AFAIK). Stefan "owner of a X201s which runs about 8 times faster than a Cubietruck when compiling Elisp code.

Re: [Arm-netbook] About, the rk processor.
Intel is on about the same ballpark as the big arm tablet chips but they can't shrink it any further. They got this low simply from node shrinks, but at this point making a new core design only for the tablet market would require very high sale volumes. And they failed to infiltrate the tablet market so...They even canceled their atom line, only the premium Core M for products like the 12' apple macbook, which don't seem to gather much traction either.

Glad to hear it! The rk3288 does sound faster judging by the specs and considering what you said, just now I mean, it is the better choice. I wonder how fast it will be with the eoma standard? Probably at least 4x faster than the fastest processor on that "x200 libreboot device I am using." Yeah I know its not as good as what your planning, but I can wait for ya. This is good news. Also, it is a quad core processor and uses very little wattage hah. I am curious by the way, how much does the intel crap use for wattage traditionally... Probably an insane amount I imagine. :) (I am glad because that will give more power to arm in the future.) ;) Thanks for the info hehe...

[Arm-netbook] About, the rk processor.
something interesting I saw is that in the update picking a processor, it shows rk3188 as the rockchip processor you were going to reverse engineer. on the other hand, your rhombus-tech link shows that your looking at rk3288? Not to be annoying constantly, but I am curious are you looking at one or both? I appolgize if there is something I may have missed. ___ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk
