1
00:00:00,160 --> 00:00:07,279
So, let's open up by busting that Thunderbolt is only for Macs myth. It

2
00:00:05,279 --> 00:00:10,880
was co-developed by Apple and Intel, but the full rights were eventually

3
00:00:08,800 --> 00:00:15,040
transferred to Intel, and now anyone can implement it. And since I've got my

4
00:00:13,040 --> 00:00:20,000
history lesson hat on, I might as well give you guys another little factoid.

5
00:00:17,840 --> 00:00:24,160
The original prototype cenamed Light Peak was actually an optical technology,

6
00:00:22,080 --> 00:00:29,119
which would have enabled higher transfer speeds and longer cables. But since

7
00:00:27,039 --> 00:00:33,600
copper can carry power in addition to data, and Intel saw better than expected

8
00:00:31,439 --> 00:00:37,440
results when testing with copper, all of the Thunderbolt cables you see today

9
00:00:35,680 --> 00:00:40,559
will have connectors on each end that look exactly like mini DisplayPort, but

10
00:00:38,960 --> 00:00:45,680
with little lightning bolt symbols on them and with only copper wires inside

11
00:00:43,280 --> 00:00:51,520
them. But what do those wires do, Ven Lionus? Well, they carry a combination

12
00:00:47,840 --> 00:00:53,920
of PCI Express and DisplayPort on one

13
00:00:51,520 --> 00:00:58,239
serial signal, as well as a DC connection for power, all wrapped up in

14
00:00:56,160 --> 00:01:03,120
one cable. This means that the Thunderbolt interface can be used to

15
00:00:59,920 --> 00:01:05,280
connect and power display, audio, and

16
00:01:03,120 --> 00:01:08,320
storage devices, as well as USB, FireWire, and gated Ethernet via

17
00:01:06,799 --> 00:01:13,040
adapters. I mean, the sky's is pretty much the limit. To top that off, you can

18
00:01:10,560 --> 00:01:17,040
run up to six total devices at a time off of a single connector by daisy

19
00:01:15,360 --> 00:01:21,680
chaining them all together or by connecting to a hub. Cool stuff. And

20
00:01:19,920 --> 00:01:26,240
while I don't think it's fair to say that Thunderbolt 1 took the market by

21
00:01:23,600 --> 00:01:31,040
storm compared to USB 3, it was very expensive, it was certainly a standard

22
00:01:28,479 --> 00:01:35,759
unlike anything that we had seen before. And it continues to evolve. In 2013,

23
00:01:33,680 --> 00:01:41,119
Thunderbolt 2 arrived with some big changes. Bandwidth was doubled to 20

24
00:01:38,320 --> 00:01:44,960
Gbit birectional, enough to watch 4K video while simultaneously running a

25
00:01:43,119 --> 00:01:50,799
high-speed storage device over one cable. And maximum transfer speeds were

26
00:01:47,680 --> 00:01:52,799
raised to 1,500 megabytes per second,

27
00:01:50,799 --> 00:01:56,720
though overhead and PCI Express limits keep you from hitting speeds even close

28
00:01:54,240 --> 00:02:01,040
to that max spec in the real world. On top of that, it maintained the same

29
00:01:58,560 --> 00:02:04,920
connector, which means V1 and V2 are intercompatible. The link will simply

30
00:02:03,119 --> 00:02:09,920
operate at the speed of the slower device. All right. Well, that's it then,

31
00:02:07,280 --> 00:02:13,520
right? 20 Gbit per second simultaneously with 4K video and you get your

32
00:02:11,680 --> 00:02:18,440
high-speed storage through one cable. It's that I mean, that's enough, right?

33
00:02:14,920 --> 00:02:20,640
No, we need more

34
00:02:18,440 --> 00:02:23,520
power. Excuse me. Not really sure what happened there. Anyway, we need more

35
00:02:22,080 --> 00:02:28,239
power. And by that, I mean we need higher speeds and greater capabilities

36
00:02:25,280 --> 00:02:33,040
with less actual power consumption. 50% less if we can rely on a leaked slide of

37
00:02:30,319 --> 00:02:36,319
Thunderbolt 3 specs from April 2014. This new format is rumored to come with

38
00:02:34,800 --> 00:02:40,879
a doubling of the current Thunderbolt bandwidth from 20 to 40 Gbit per second.

39
00:02:38,800 --> 00:02:47,040
And it'll be capable of four modes, including HDMI 2.0. Woo, cool. It should

40
00:02:44,640 --> 00:02:51,760
have support for PCR Express Gen 3 and is rumored to be capable of charging

41
00:02:48,879 --> 00:02:56,480
devices that require up to 100 watts of power. The bad news is that it's also

42
00:02:54,480 --> 00:03:01,840
rumored to require a new connector. So, adapters will be needed for backwards

43
00:02:59,560 --> 00:03:05,440
compatibility. Now, while we haven't yet reached the 100 Gbit per second maximum

44
00:03:03,840 --> 00:03:09,360
speeds over Thunderbolt that Intel promised when they released the protocol, I've seen unofficial

45
00:03:08,000 --> 00:03:13,040
statements projecting that speed by around 2020, but nothing confirmed yet.

46
00:03:11,599 --> 00:03:16,400
We're still very early in the life cycle, and at the rate Thunderbolt's

47
00:03:14,640 --> 00:03:21,200
been moving, I'd be surprised if it takes that long. And I'm very excited to

48
00:03:18,239 --> 00:03:26,239
see the future of this. It's uh very promising, but still very expensive

49
00:03:24,120 --> 00:03:31,120
technology. Speaking of things that are very expensive, going to the store and

50
00:03:28,879 --> 00:03:36,400
buying razor refills for I mean, for some reason, why do they cost so much?

51
00:03:33,760 --> 00:03:40,959
They're pieces of metal and they're in like plastic. Metal and plastic. Not

52
00:03:38,720 --> 00:03:44,159
that expensive. Well, I don't think they should be that expensive, and neither

does today's episode sponsor, dollarshave club.

54
00:03:45,799 --> 00:03:53,040
dollarshaveclub.com is the place to go if you want to join the club and stop

55
00:03:49,840 --> 00:03:54,799
paying way too much for high quality

56
00:03:53,040 --> 00:03:58,720
razors and for that matter other bathroom supplies. They've got a range

57
00:03:57,120 --> 00:04:03,599
of different razor options, everything up to the executive with six blades.

58
00:04:01,439 --> 00:04:07,120
They've got their Dr. Carver shave butter which goes on clear so you can

59
00:04:05,200 --> 00:04:12,239
see what you're doing. And they've even got their one wipe charlies which are

60
00:04:09,840 --> 00:04:15,840
peppermint scented butt wipes for men. And they've even got an aftershave now

61
00:04:13,840 --> 00:04:19,120
too. These guys are like trying to take over the world. Well, okay, maybe not

62
00:04:17,359 --> 00:04:23,759
quite the world, but at least the US, Canada, and Australia, where people can

63
00:04:21,840 --> 00:04:28,240
join the club and for a reasonable amount of money per month, make sure

64
00:04:25,600 --> 00:04:32,160
that they're always getting a nice clean shave. So guys, check out the link that
