eight cores 12 cores 16 cores
it wasn't long ago that just single core cpus were the norm on home computers but
these days we're seeing ever increasing core counts for less and less money but
if we can have lots of cores on just one CPU
what's preventing the powers that be from just putting multiple CPU sockets
on the motherboard and letting us have even more cores that way i'm glad you
asked well as it turns out we actually did have multi-CPU platforms for
consumer-grade chips for quite a long time in fact you can find them going all
the way back to the pre-pentium days when we were all rocking
486s in our desktop rigs but
understandably these setups were quite rare for home users with one of the big
reasons being simply cost now although a good CPU these days isn't
exactly cheap it pales in comparison to
many popular cpus of the late 1980s and
early 90s the 486 for example cost
around a thousand dollars when it launched and remember guys this was a
single core processor another reason was that most applications for Windows were
simply not designed to take advantage of multiple processor cores i mean this is
still true to a lesser extent today especially with games but
multi-threading for most consumer applications was almost unheard of until
the mid-2000s and if you were doing something at home that would benefit
from parallel core such as video editing
well you're back to that same problem of having to take out a second mortgage but
as time went on silicon prices fell and we ended up with some multi-CPU
platforms that became somewhat popular with home users
one was athlon mp released in 2001 with
the mp standing for multiprocessor it
was AMD's first ever attempt at a dual socket platform and while it was
designed with servers and workstations in mind it did gain some traction among
enthusiasts and a small handful of systems built around athlon mp even made
their way onto store shelves at local retailers another platform that was more
specifically focused on home users was Intel's skull trail from 2008. now this
dual CPU solution was also derived from
a server or workstation oriented product in this case Intel z online but the
motherboards had more features that home users and gamers would want like
overclocking and fewer of the more obscure standards you'd typically see on
a server board like remote management
Intel built skull trail as the ultimate gaming platform partly because of the
raw power that you could get from two cpus and partly because it could support
multiple graphics cards in NVIDIA sli
without an NVIDIA chipset which at the time was a pretty huge deal
unfortunately the platform is mostly remembered as a failure because it was
you guessed it extremely expensive especially when you factor in the
high-end cpus that were required in order to use it not to mention that the
dual cpus didn't provide much gaming benefit even though it was kind of
marketed towards gamers and enthusiasts AMD's similar quad fx suffered a similar
fate as performance simply didn't stack up compared to the high costs and
demanding power requirements these days most folks running dual CPU setups at
home are using repurposed workstation or server boards but despite the greater
prevalence of multi-threaded programs these enthusiasts still remain a tiny
minority of users you see unlike earlier
high-end platforms where you could only get four or eight cores maximum in a
single socket shrinking transistor sizes and greater
power efficiency mean that we can now have as many as 64 cores on a single CPU
package like what we've seen with AMD's latest threadripper processors and
especially when you factor in simultaneous multithreading which allows
one core to work on two or more threads at the same time
that many cores is enough performance for just about any home user even if
you're doing something insanely demanding then you've got the fact that
there are potentially latency issues with having two physical processors on
the same board that you don't deal with in a single socket system that means
that multi-threaded workloads even if they are well designed won't necessarily
scale perfectly when you add more physical cpus which you can learn more
about in this video on our sister channel minus tech tips so the short
answer to the question we asked at the beginning of the episode can simply be
summed up as diminishing returns in much the same way
that adding a 13th subwoofer to your car couldn't possibly make your neighbors
any more upset than they already are adding a second or third or fourth CPU
to your motherboard is probably not going to make much difference to the
workloads you actually care about but you know what you should care about
