do you remember the last time you used a cookie cutter to make treats for your
0:03
weekly techwiki viewing party well even if that was for a
0:08
different occasion odds are that your cookies came out looking slightly
0:12
different no matter how identical you tried to make them this is the same
0:17
concept behind binning a term used by the manufacturing industry to sort
0:20
things like for instance processors and memory modules by quality once they're
0:25
manufactured you see although manufacturing processes for computer
0:29
chips are extremely precise there's going to be some variation between them
0:33
due to the intricacies involved in fabricating such tiny complicated
0:38
components for example a CPU with a certain microarchitecture which you can
0:42
learn more about in this video up here will have targets for performance power
0:47
management and thermal output all set by the manufacturer if a certain sample
0:51
hits these targets it will be bined at a higher quality and end up being sold as
0:56
a higher-end product but if it falls short it will end up being a more value
1:02
oriented product multi-core CPUs illustrate this very well let's say you
1:06
have a core I3 from Intel sitting in your rig right now although it's a dual
1:10
core processor the actual die might have actually been four cores if a chip has a
1:16
core that isn't up to par but has others that function as intended the defective
1:20
cores can be disabled and the chips sold at a lower tier so that I3 in your
1:25
machine could have actually been an i5 but some small thing went wrong in the
1:29
factory on the other hand the highest bin consumer grade Intel CPUs often
1:33
become the unlocked K series chips marketed to overclockers as these are
1:38
typically the ones that perform the best without having to crank the voltage way
1:42
high or putting out an insane amount of heat even so due to the minute
1:46
differences between individual processors overclocking results will
1:50
vary between even favorably bended unlocked chips the so-called silicon
1:55
Lottery you hear Enthusiast talking about the same concept also appears in
1:59
graphics cards as well often times when there's a new GPU release that isn't
2:03
something on the extremely high end you'll see a review that says it has the
2:07
same GPU as a more expensive model but with X number of compute units disabled
2:12
this is often due to binning where a GPU might have a block of compute units that
2:17
don't make the cut quality-wise so they're disabled instead and sold as a
2:21
say GTX 950 instead of 960 so hold on a
2:25
second you're telling me that I can turn on extra cores that might be hiding on
2:29
my CPU or GPU and get some free performance if I slap on a better cooler
2:34
or something right unfortunately no that party has kind of ended years ago it was
2:39
more commonly possible on certain products through some BIOS trickery or
2:43
maybe a firmware update here or there but these days most major manufacturers
2:47
physically disable the connections between inactive cores and the rest of
2:51
the processing unit so they can't be used at all by consumers but even so
2:56
don't feel bad if you bought a lower Bend chip just remember remember that
3:00
you saved an innocent CPU from being melted down for gold and silicon and
3:05
didn't even have to make a monthly donation because you saw a depressing TV
3:09
commercial tunnel bear VPN lets you connect to 20 different countries
3:13
allowing you to browse the internet and use online services as if you're in said
3:17
different country they have an easy to use app for iOS Android PC and mac and
3:22
they even have a Chrome extension if you just want to have like one thing going
3:26
in that country and not everything just choose a country in the app turn tunnel
3:29
bear on and watch as your bear tunnels your internet connection to a new
3:34
location when you turn tunnel bear on two things happen your connection gets
3:37
encrypted with AES 256bit which is awesome and your public
3:42
IP address gets switched so you can show up as if you're in a different country
3:46
like I just said you can try out tunnel bear VPN with 500 megabytes of free data
3:50
with no credit card required and if you want to upgrade to unlimited data you
3:54
can save 10% by going to Tunnel bear.com

Linus if you like the video like it if you dislike the video dislike it comment
4:01
down below if there's like stuff you want us to cover someone released a
4:05
really good comment recently that had like four different things that we haven't covered yet that were great
4:09
ideas so we're probably going to do those don't forget to subscribe and
4:12
check with Channel Super Fun we do like weird stuff this Probably sounds
4:16
horrible in the mic and there's like things bouncing off of me and it's bad
4:20
but if you didn't like that sound you should go there don't know how that works go there
4:26
anyways
