what is DDR for I think the least helpful explanation I could give for
0:04
this topic is well it's short for double data rate fourth generation synchronous
0:08
Dynamic random access memory and at this point you're probably sitting there
0:11
going Dr ramit Linus those are just words I want to know what it does okay
0:16
fine let's start with what memory or RAM is actually for in your system let's
0:20
imagine for a moment that uh a builder is like a CPU doing work and tools are
0:26
like data so a processor's cache is a
0:29
very small ount of incredibly fast storage directly on board this is kind
0:32
of like the hands of our Builder he can't keep much there but it's really
0:37
fast to access next up is RAM or working
0:40
memory this is whatever our Builder can store on his belt or nearby as he works
0:45
it's slower to get to than cash and he can't keep everything he could possibly
0:49
need there but it should be enough to complete whatever is the current task
0:53
next up is mass storage which would be your SSD or hard drive this is much
0:57
slower than RAM to access kind of like going down the ladder to grab something
1:01
from his truck and then if we wanted to keep the analogy going even after it's
1:04
worn out it's welcome we could say that off-site storage like over the Internet
1:08
is kind of like driving to the store to buy a new tool outright it's that much
1:11
slower again so there you have it RAM is
1:14
the tools or data bringing it back to computers that your CPU needs to
1:19
complete its current task or tasks so the more of it you have the less often
1:24
you the Builder will need to go down the ladder to retrieve things and the faster
1:28
it is the less downtime time you'll need to deal with every time you realize
1:32
you're holding your drill when actually you need a circular saw on to ddr4
1:36
specifically it's the next evolutionary step forward in memory technology from
1:41
DDR 3 I know go figure right but jck
1:44
hasn't been sitting on their thumbs for the past half a decade and this isn't a
1:48
small upgrade compared to DDR3 it offers over 20 new features so I think it goes
1:53
without saying that it's not backwards compatible and you'll need a new
1:57
motherboard and CPU to use it sounds expensive why would I even want that
2:01
lonus well first up it's going to improve performance aside from allowing
2:05
much higher clock speeds we're talking 3200 MHz stock ddr4 is a bigger change
2:12
than it might at first appear to be with some clever architectural Wizardry
2:15
designed to improve performance particularly in multicore systems next
2:20
up we've got capacity right off the bat ddr4 will be capable of double the
2:25
density per die but perhaps equally important is that it can support up to
2:29
to eight dies per package instead of four which combined translates into an
2:34
effective quadrupling of DDR 3's theoretical maximum capacity of 128 GB
2:40
per module yeah 512 GB memory sticks
2:43
baby but of course for now that benefit along with some of the others won't be
2:47
very applicable to home users a couple more such improvements are the 40% or so
2:52
reduction in power consumption due to ddr4 better power management and lower
2:56
operating voltage as well as its support for much more advanced error detection
3:02
prevention and correction this last one is going to be key as capacities grow to
3:07
the point where errors become actually inevitable speaking of inevitable errors
3:12
going to the store to buy replacement razors if you haven't already signed up
3:16
for Dollar Shave Club yes it's been a while since we've talked about Dollar
3:19
Shave Club but that doesn't mean that the scary man with the weapon
3:24
obscenities private Army and trained bear is gone oh no he's still watching
3:29
you in the bathroom or maybe that was me someone's watching you shave I mean what
3:33
did you think we were watching you doing that's gross we'll never know who it was
3:36
anyway the point is that for just a few bucks a month Dollar Shave Club delivers
3:40
high quality razors and other bathroom supplies straight to your door the club
3:43
is available in the US Canada and Australia for my friends down under and
3:47
aside from their great razor blades and shave butter they've got one wipe
3:51
Charlie's butt wipes for men for my enemies down under if you catch my drift
3:55
anyway that's pretty much it head on over to dollarshaveclub.com and join the to
4:00
start shaving time and shaving money thanks for watching guys like this video
4:03
if you liked it dislike it if you disliked it leave a comment if you have suggestions for future episodes of
4:07
fastest possible or just anything to say to us about this particular one I think
4:11
that's pretty much it don't forget to subscribe if you haven't already and I'll see you again next time
