so we're going to be looking at something pretty cool today from Intel it's not a new product but it is a new
software application that they've just released it is a Windows Gadget which
basically means it's a little application that runs either in the Windows sidebar which is over here on
the right outside of the camera's reach that's in Windows Vista or on Windows 7
you can actually move them around wherever you want so it's the Intel
turbo boost Gadget so you can see right here this is an Intel Core i7 extreme
965 processor 3.2 GHz there's nothing in
the turbo boost bar right now now our CPU temperatures are around 50° which is
a very comfortable CPU temperature maybe a little high for this CPU but we're
going to go create an artificial workload and I'm going to show you what
the turbo boost Gadget does so here is
the workload we've created a one thread so that means it is a CPU workload that
only takes advantage of of one CPU out of this quad core so something like a
game or an older application might only
make use of a single thread now we're going to run it on CPU 1 which is what a
single-threaded application would typically run on here we go now if you
just Cruise right on over here you can see that core0 to the left to the left
everything you own in a box to the left yeah core0 right there is running at 70°
and all the other cores are much cooler that's because this is a single-threaded
application now if you go over to the turbo boost uh widget that is oh sorry
it's a gadget gadget not a widget it is 3.47 GHz now and it's blue bar is all
the way to the top so that's a 3.2 GHz processor all the way up to 3.47 GHz now
if I change my workload so if I run a four threaded workload and if I change
it around so that I assign it to any CPU
it wants to be on and if I click the right thing it goes a lot better okay so
CPU Affinity run on any CPU torture test
and run we can go back over to my Cort
temp monitoring you can see that all CPUs are now being stressed and turbo
boost only goes up to 3.33 GHz that's
because it's overclocking all four cores
now this is an older i7 CPU and the newer i5s and i7s on socket
1156 actually have better turbo boost
that can provide up to a 20% performance Improvement according to the hardware
connects review on these CPUs so this only goes up a couple of speed bins one
for a multi-threaded application and two speed bins for a single threaded
application where whereas the i7 860 and 870 can go up to five speed bins for a
single threaded application with the I5 750 going up four speed bins for a
single threaded application so thank you for checking out my Linus Tech tips blog
