intel core i7-4790k

iT’s hard  To believe, but  after  decades  of
making CPUs, Intel has finally broken the 4GHz
barrier with its Devil’s Canyon—which isn’t really  all  that  new,  of  course.  It’s  essentially  an
Intel Core i7-4770K but made to overclock like
a mother. To do that, Intel beefed up the CPU’s
power  delivery  with  additional  capacitors  and
used a “next-generation polythermal interface
material” that’s supposed to be far better than
current  thermal  paste  or  goo  in  4770K  parts.
This, loyal readers, adds up to a chip that starts
at 4GHz and has a turbo boost of 4.4GHz.
Other  than  that,  it’s  still  the  same  Haswell
microarchitecture we’ve come to love. The 22nm
question, though, is how far could we overclock
this chip that was built explicitly for overclocking?  A  duplicate  part  in  this  month’s  Build  It
section  hit  4.7GHz  on  a  CLC.  We’re  expecting
more—but not much more—as few have taken
Devil’s  Canyon’s  parts  above  the  best  Haswell
chips.  In  many  ways,  the  best  way  to  think  of
Devil’s Canyon is that every chip is “good,” while
it was a crap-shoot with the original Core i7-4770K parts.
