in a recent video you guys called me out pretty hard it was the one here about
the performance of CPUs with varying numbers of processing cores when gaming
at the same time as performing other
intensive tasks in the background and many viewers were displeased with the
methodology that I used to obtain my numbers now of course I didn't dive
headlong into hours of testing without some kind of hairbrain theory about how
it would work so I was pretty sure my numbers were fine but one should never
be afraid to question one's own assumptions and whatever the result is
whether I was right or the critics were right I'm here to share them with you
just like soon I'll be sharing my thoughts on the upgradeability of the
iMac 27in retina 5K allinone PC that I've been using as my daily driver but
first the
intro ensure Swift Victory with Corsair
highly responsive lightweight gaming mouse the saber RGB click now to learn
more so I guess I should explain what people were so upset about before I get
too much further into this because the idea behind that video was to find an
extreme workload scenario first then see
how it affected a variety of processor configurations a fair amount of time was
actually spent developing The Benchmark scenario that I'd be using in order to
ensure that it put enough load on my
configuration to let the more powerful CPUs stretch their legs while not
putting so much load on my configuration that absolutely everything choked to the
point where it didn't function so I decided that instead of removing the
cooler swapping out the chip reapplying thermal compound then putting a new
motherboard on the test bench each and every time I needed to see how my stress
test was going to affect another CPU class I was going to Simply use the BIOS
of the motherboard that I was using to take my best processor an i7 5960x
extreme Edition and limit it artificially to the specs of the other
contenders in the test now hold on a minute lonus can you do that in the vast
majority of cases no no you can't I had
a lot of people ask why I didn't include AMD processors in that test and this is
actually the answer since the point of the video was more cores versus fewer
cores not Red Team Versus blue team anyway there was no real point and it
would be a lot more work because I'd have to swap benches and deal with
drivers in between runs every time all
right lonus so then in what situation would this artificial CPU faking
theoretically work if every CPU you're
simulating was designed with the same processor architecture so in this case
everything was Haswell based and has the same non-adjustable specs so cash memory
Technology support motherboard socket Etc and differs only in terms of the
parameters that we can change frequency multiplier hyperthreading support turbo
boost ratios Etc then they should
perform identically now I did Fudge things a little bit further than that
and simulated CPUs with completely different RAM support DDR3 versus ddr4
and different cash amounts but none of my workloads were hyper cash dependent
to my knowledge and I had already found DDR3 versus ddr4 performance to be
pretty much a non-factor outside of synthetic benchmarks in the Apples to
Apples comparison I had done previously which you can see here so I went for it
and here we are after all that Preamble ready to test whether my methodology was
okay or not cue the charts and graphs I
ran a variety of benchmarks on both a core i7
5960x that had memory channels cores hyperthreading and turbo boost adjusted
to simulate a core i5 4670k and a Pentium
g3258 and then I ran the same benchmarks on the actual chips themselves with the
only differences in theory being DDR 31866 RAM versus ddr4 2400 RAM and the
Oni cash sizes and honestly I was both
pleased with my theory because it's been
somewhat validated now cuz the results really are very close for the 46 70k and
also a little disappointed because I can see that as cash sizes really fall off a
cliff this Theory cannot be applied our
simulated g3258 outperformed our real
one by a fairly significant margin in some benchmarks so there you have it I
still stand behind the way I ran those tests because the time savings was
definitely worth the margin of error that was introduced by doing it that way
especially considering that the point of the video wasn't the exact models of the
CPUs but rather their number of cores and approximate multitasking proficiency
but I see that if I was looking for a way to save time on our normal CPU
performance reviews this obviously isn't it and we'll have to continue doing
board and Chip swaps moving forward especially if we want to measure things
that would be different no matter how close you get the specs due to Intel's
binning process like heat output and power consumption oh and speaking
speaking of Intel CPUs today's episode sponsor Gigabyte wanted us to show off
their new P35 V3 gaming notebook an
extremely slim gaming notebook which is powered by a fourth gen Intel Core A7
mobile quad core processor this baby features an NVIDIA GeForce GTX
980m a 15.6 in 1080P monitor the panel
type may vary by region it can support up to 16 gigs of DDR3 memory up to a 512
gig SSD and up to 2 terby of hard drive storage one of the other pretty amazing
things about this bad boy is that it's only 20.9 mm thick and weighs in at 2.2
kg it's extremely easy to transport and with its rear exhaust your hands should
remain cool and comfortable even during a heavy gaming session so if you're in
the market for a new gaming laptop oh yeah did I mention it actually has an optical drive they squeezed an optical
drive into this thing so sorry if you're in the market for a new gaming laptop
maybe you're getting you know way more Christmas money than I ever did or
perhaps you need to pick up a new notebook before the new school semester starts check out the Gigabyte P35 V3 get
