Intel Devil’s Canyon Processors Officially Announced – Core i7-4790K Clocked To 5 GHz During OC Competition, Costs $339 US

Intel has officially announced their upcoming Devil’s Canyon processors
which are also regarded as the Haswell Refresh K-Series. Built for
overclockers, the Devil’s Canyon processors which include the Core
i7-4790K and Core i5-4690K feature impressive specifications and a new
design scheme which allows better overclocking and more performance
out-of-box.

Intel Devil’s Canyon Processors Officially Announced

The Core 4000 series processors based on the Haswell
microarchitecture were launched a year ago at Computex 2013. The
processors featured the latest 22nm core 3D Tri-gate transistors
technology which improved the IPC and efficiency by a decent amount of
Ivy Bridge. While the Haswell processors were met with a great response
and backed by a variety of overclocking features, the processors didn’t
happen to be great at overclocking due to the cheaper application of TIM
between the IHS (Internal Heat Spreader) and the Haswell silicon itself
which resulted in the heat to remain trapped between the chip due to
poor contact.

Intel seems to finally be fixing this issue once and for all with
their upcoming Haswell Refresh processors. The K-Series Haswell Refresh
processors in specific are codenamed Devil’s Canyon which would offer
users an improved design that incorporates updated packaging materials,
improved TIM (Thermal Interface) and processors that are specifically
re-engineered for enhanced performance and overclocking. So many users
who have been waiting for Intel to update their TIM design since Ivy
Bridge can now check out the new processors for their overclocking
needs. To be specific, Intel is going to use Next Generation Polymer
Thermal Interface Material (NGPTIM) inside their Devil’s Canyon
processors offering better heat dissipation to allow overclocking.


Intel Core i7-4790K

The Core i7-4790K will be the flagship processor of the Haswell
Refresh lineup and the first 22nm consumer CPU to obtain clock frequency
of 4 GHz and a maximum boost clock of 4.4 GHz which is also a first for
Intel. It will feature 4 cores and 8 threads along with a fully
unlocked design which will allow users to overclock the chip past the
limits thanks to the improved thermal design and updated package
materials. The Core i7-4790K will feature a 88W TDP and would come with
the latest HD 4600 graphics chip clocked at 1250 MHz. The pricing is
suggested around $339.99 US.


Intel Core i5-4690K

The Core i5-4690K will be the fastest Core i5 Series processor of the
Haswell Refresh lineup featuring a clock frequency of 3.5 GHz and a
maximum boost clock of 3.9 GHz matching the specs of the Core i7-4770K
in a way. It will feature 4 cores and 4 threads along with a fully
unlocked design which will allow users to overclock the chip past the
limits thanks to the improved thermal design and updated package
materials. The Core i5-4690K will feature a 88W TDP and would come with
the latest HD 4600 graphics chip clocked at 1250 MHz. Pricing is not
known at the moment. The pricing is suggested around $242.99 US.


Intel Pentium G3258:

Aside from the Haswell based Core processors, Intel also announced
their 20th Anniversary Pentium edition unlocked processor. The Pentium
G3258 is a dual core with two threads featuring a core clock of 3.2 GHz.
It doesn’t come with Turbo Boost tech but will be supported on both
8-Series and 9-Series platforms unlike Devil’s Canyon which will feature
support on just the 9-Series chipset based Z97 motherboards. Featuring
the 22nm Haswell architecture, the chip comes with 3 MB of L3 cache and a
TDP of 53W. The instruction set includes SSE4.1, SSE 4.2, EM64T and
VT-X. The box prices suggest a retail cost of around $72.99 US.

As far as launch and compatibility is concerned, motherboard makers are trying their best to release BIOS for their Z87 products that allows Devil’s Canyon support. So far, ASUS has
been successful to offer one and we have already seen the results
regardless of the targeted compatibility with Z97 chipset based
motherboard. As for launch, the processors will hit retail by June 21st
while boxed variants will come to global markets by August 2014.

Intel Devil’s Canyon Overclocking:

We will start seeing some official results in just a few minutes
since the Devil’s Canyon OC event hosted by Intel is going to begin
soon. Infact, we already have a verified 5 GHz result of the Core
i7-4790K which was maintained at 1.400V from Overclock.net forums user
“Dhenzjhen@OCN”. The chip was able to deliver a score of 16285 3D Marks
in 3DMark 05 which heavily relies on the CPU performance. From what
i’ve heard, this overclock was done on air so we can be looking at some
big numbers when LN 2 cooling comes in to action.

Intel Devil’s Canyon processors also transfer all the great overclocking features introduced on Haswell as detailed in our review such
as a dynamically adjustable and fully unlocked Turbo Boost Technology
limit that ensures users get the most out of their processors when they
need it. Core ratios have been unlocked  upto 80 in 100 MHz increments
while the CPU voltage is completely controllable via the iVR
(Integrated Voltage regulator). DMICLK or BCLK allows for an unlocked
PCH clock controller with increments upto 200 MHz while PEG and DMI will
offer variable/adjustable ratios based on the BCLK frequency.
Similarly, the GPU core also features an unlocked design that allows for
frequency adjustments (60 Ratio in 50 MHz increments) and fully
programmable voltage via iVR. An unlocked memory controller allows for
upto 2933 MHz overclock on the DDR3 modules.

Intel has provided key details on the upcoming iVR through which
voltage on CPU and GPU could be dynamically adjusted. Currently, voltage
management is accomplished with the use of external VRM’s on the
motherboard. There are in total four voltage override modes through the
iVR module on Haswell chips which are accounted for when running the
processor in default and overclocking mode. With the next generation
Haswell processors, we would be looking at an increased BCLK of greater
than 167 MHz (non-continuous) compared to the peak 116.95 MHz on Ivy
Bridge along with a select CPU PEG/DMI ratios of 5:5, 5:4, 5:3 which is
quiet impressive. The next few slides details various performance tuning
ratios available on Haswell core for CPU/GPU/DDR/PEG,DMI and Ring.
