[Anand] AMD's Lightning Bolt: Low Cost Thunderbolt Alternative for USB 3.0/DP - Page 3

post #21 of 68
Lightning Bolt sounds better than Thunderbolt. Not to mention that lightning bolt makes more sense than thunder bolt. rolleyes.gif I don't like active cables, though. And tb's upper limits use fibre, where it would either be very expensive (comparably) w/ copper for power included, or lack one of it's features (power).

are you sure? initial this was light peek, but it was dropped due to costs. (I may be wrong)

Just like how PCI-Express replaced PCI, PCI-X and AGP as a universal expansion slot for motherboards, Lighting bolt could become the universal connector for all external peripherals. It might not provide the incredible bandwidth that thunderbolt can provide, but it's cheaper to produce and lets face it, 5 Gbit/s bandwidth is more than enough for keyboards, mouses, monitors, external drives and such.

OHHHH.... Actually that may be somthing im interested in. I use autodesk for work but I do have a desktop but it would make it easier if I could do it on mobile sometimes in certain situations.

Thanks for that. I am going to look into it. +rep

The down side I see to this whole external GPU crap is power consumption. I mean lets face it, a machine right now that will run autodesk well already has a pretty low battery life. So you're talking about externally running a graphics processor, with the possibility of also running a hard drive, mouse, and keyboard off of it at the same time? How well do you guys really think this is going to pan out for the life of a laptop battery?

Even with Li-Ion, Li-Poly batteries, we're seeing poor battery life. Granted, we can add a lot more cells and still not have a lot of weight, but all of that material has to go some where. If we're adding in all of this extra battery to power something externally, why not just make this crap work inside the computer? It seems like a lot of wasted development that could be better spent on integration with existing platforms and advancement of current technologies of which we haven't even found the full potential of.

There's one definite advantage Lightning Bolt has over Thunderbolt:

LB = DisplayPort 1.2
Tb = DisplayPort 1.1a

AKA, Lightning Bolt has nearly TWICE the bandwidth for displays. If you don't want to be stuck with 60hz displays for any longer, Lightning Bolt is definitely the way to go. thumb.gif

They switched to wire to make it cheaper, which lowered transfer rates. They plan to still use optic, but in the future. My main point in bringing it up was that for them to get near their upper limits, they'd have to use optics. And if they used optics it would probably cost too much to also include power.

These are intended for docking purposes when there's a wall outlet that they're plugged into.

That I can agree with it we had to use it on HD3000 graphics for school so many rage moments when it bricks up on you half-way through something even the jump to gt8800 was noticeable I cant imagine how much better it would be on a 500/7000 series card running off thunderbolt.

I mean, what would be the point? Anyone have an idea for external gpu?

Because you leave the video card at home with your full sized mouse, keyboard and monitor. that way you can have the power of a desktop while at home, while being able to leave all that, larger, power consuming stuff, at home and take your nice, light laptop with more than an hour of battery life with you on the road/school/whatever.
