HOW WE TEST


For our testing, we standardised on Nvidia’s
GTX 1080 Ti FE as our graphics card. At
1080p, this shows the largest difference in
gaming performance you’re likely to see
with current generation GPUs. For memory,
we’ve used high-end G.Skill Trident Z and
Flare X DDR4-3200 CL14 memory on all
modern platforms, in either 2x8GB or
4x8GB configurations.
The motherboards used in testing
include the MSI Z390 MEG Godlike and
Gigabyte Z370 Gaming 7 for Coffee Lake,
MSI Z270X Gaming M7 for Kaby Lake/
Skylake, Asus X299-A Prime for LGA2066,
and MSI X99A Gaming Pro Carbon for
LGA2011-3 on the Intel side of things. For
AMD platforms, we used the Gigabyte X470
Aorus Gaming 7 Wifi for Ryzen, and the
Asus Zenith Extreme for Threadripper.
Liquid cooling was used on all CPUs.

PERFORMANCE RESULTS


Thanks to the Meltdown and Spectre
exploits, and the patches to Windows
intended to remedy those exploits, I had to
retest every single processor.
Gaming performance is tested in ten
games, representing a variety of genres and
game engines, all using the GTX 1080 Ti FE.
The games are running at 1080p Ultra
settings, with 4xMSAA where applicable
and FXAA/SMAA otherwise.

Core i9-9900K


INTEL £500


Fastest processor for games, streaming, and more


The best processor can
mean a lot of things. For
pure gaming, the Core
i9-9900K is overkill, unless you’re
planning on an extreme build with
a top-tier graphics card. For those
that do more than just playing
games, however, the Core
i9-9900K reigns as the overall
king of performance. It’s the
fastest mainstream CPU for the
LGA1151 platform, period.
The Core i9-9900K doesn’t
have the core counts found of
chips like the i9-7980XE or
Threadripper 2990WX, but it
boasts the highest clockspeed of
any current processor, with
excellent per-core performance.


Put it in a good enthusiast
motherboard and you’re likely to
see all-core ‘stock’ clocks of
4.7GHz, with lighter workloads
hitting 5.0GHz out of the box.
You’ll need to bring your own
cooling, which is Intel’s approach
to all its K-series and X-series
processors, and definitely don’t
skimp. The i9-9900K can draw a
lot of power and tends to run
hotter than the previous gen,
thanks to the extracores.

Core i7-9700K


INTEL £380

Excellent gaming performance at a lower price


Intel’s Core i7-9700K is
an interesting step
down from the
i9-9900K. It sports the same
number of CPU cores, and
clockspeeds are similar as well,
with most Z390 boards running
the chip with all-core turbo
speeds of 4.6-4.7GHz.
In games, it’s effectively tied
with the more expensive Core i9
but costs around £120 less.
That’s because for the first time,
Intel has shipped a Core i7
without Hyper-Threading.
It’s a balancing act between
price, performance, and features.
Compared to the Core i7-8700K,
it has 33 per cent more cores,

which generally translates directly
into multithreaded performance.
Hyper-Threading typically only
improves performance by 10-15
per cent, so it’s a net win. The lack
of Hyper-Threading also means
the i7-9700K doesn’t get nearly
as hot as the Core i9, so you can
get by with a good air cooler.
If you’re livestreaming, doing
video editing, or any other serious
content creation work, stepping
up to the 9900K makessense.
