Linus, oh hey
Get it?
A Coffee Lake?! Yup
Oh like the CPU we're reviewing
Yep Oh yeah, well, you know what thanks for that
and while we're at it

The core i7 8700 K and core i5 8400 CPUs
that we're reviewing today are members of Intel's 8th generation Core Series
codename
Coffee Lake
They're built on the improved 14 nm ++ process
and they fit in the same socket as 6th and 7th gen processors, but
for those of you
rejoicing in the streets that Intel is supporting the same socket for three generations
of desktop chips for the first time in a decade.
Think again.
Neither 8th gen chips nor the 300 series motherboards that go with them are backwards compatible.
Trust us. We tried.
Intel has an excuse though at least for the new CPUs to not work in the old boards
Because the new Z370 chipset even though rumors indicate that it's fundamentally a retooled Z270
supports higher speed ddr4
2666 out of the box and
Offers improved power delivery both things that required some tweaks even to hardware
And so I don't know like maybe this is
worth making a video about like coaching people on how to watch for this stuff because
Anyone who was expecting a 200 series board to get a CPU upgrade hasn't been following Intel's pattern over the last 10 years
now AMD's announced long-term support of am4
Might bring about a change in this behavior from Intel, but that remains to be seen
AMD's history is to, sure support a socket for a long time
but with CPUs that nobody really wants to upgrade to with all of that said,
I totally get why the people who invested in fancy Z270 boards are mad right now
Architecturally coffee lake is more or less just kaby lake which itself was more or less just sky lake
No avx-512 no rebalanced smartcache I mean
Damn We're not even getting a new HD graphics chip not that I cared about that although hooray for hdcp 2.2. I guess
so
That doesn't sound very compelling
But what is is that we are finally getting a 6 core Intel chip on the mainstream
platform and at mainstream prices
But there's more it's not just a 6 core chip
Which is kind of what I would have expected them to do the entire Core i7 and Core i5
Lineup are getting the hex treatment complete with additional cache
and this is all at roughly the same TDP as the previous generation
So, if you're upset about that
Then I'm glad because this is a good thing
We all used to get upset about
Every new hardware generation, but it's ok salt can taste good. You know it's like oh
oh
Hmm like this is what it feels like when oh that's awful. Ah oh
oh, I gotta get it off my tongue
Why is this even in here
Ok I'm sorry, so this this is what it feels like when technology is actually
advancing ah
Now there are new core i3's too but those are kind of boring, and we didn't get samples
so let's get to performance of the chips that we have we are going to be doing a lot of testing this time around because
this is
Potentially a huge single generation leap in performance
so
We cracked open our previous generation Intel rig our current gen Ryzen and threw in
Core i9 and ThreadRipper for good measure so get your yeehaw ready, cuz it's
gun be one heck of a shootout and
the core i7 8700 K
Comes out guns blazing in our 1080p gaming tests it predictably trades blows at the top of the keep with its predecessor
depending on per game multi-threaded optimization
I curiously it seems to fare slightly worse overall, but it's nothing to cry about
More interesting is the core i5
8400 riding into town with
7700 K like performance at an i5 price as
For our 4k gaming tests. Well. These are some super boring if beautiful and high resolution
graphs
There's a reason that Anthony coined the term the great equalizer for 4k in the core i9 Extreme Edition video
Everything performs the same when the GPU is the bottleneck
synthetic gaming benchmarks tell a similar story
moving on to productivity oh boy
The core i7 8700 K. Kills it here easily surpassing Ryzen in
Multi-threaded tests and even approaching the core i9 lineup
Thanks to its higher core clocks
And it even decisively snatches the single-threaded crown from its predecessor
Thanks to its higher turbo and extra cash as for the core i5
8400 its lack of hyper threading does hurt it here compared to its competitor the Ryzen 5 1600 and
Since Ryzen chips are unlocked that gap could widen with overclocking
Thermals are
Not that great for the 8700 K although this seems to be at least
partially a firmware bug since when overclocked we actually got lower readings and
power consumption is higher than the last gen but
Nothing like the HEDT and workstation chips that we've been reviewing recently
Let's talk overclocking
It's pretty simple and there's plenty of fine control including per core overclocks at 5 gigahertz
Yes, my friends 5 gigahertz 6 cores. We managed a pretty decent improvement in performance on our
8700 K giving it similar Headroom to our 7700 K across the board though as always your mileage may vary
Bringing us to value and it's here that coffee lake shines
When system cost has accounted for compared to kaby lake the core i7 8700 k is on par for gaming
That's good, but at over a $100 less than that the core i5
8400 is the one that's going to be really disruptive be it for gamers or entry-level content creators in
productivity the to actually switch places
The 8700 k takes the crown here while the 8400 sits in the back seat next to Ryzen
Over although both of the new intel chips sit pretty at the top of the pile
so
was coffee lake a last-minute response to Ryzen, in some respects pricing not to mention the decision to move the
i5 line up to six core
It might be we don't know how good intel's you know corporate
espionage is you know maybe they knew Ryzen was gonna be good a
Year, and a half two years ago when they would have had to start working on this or maybe they didn't
Whatever was the case this release is a major performance win for the consumer
