simultaneous multi-threading a feature that Intel calls hyperthreading has
become a real mainstate on consumer CPUs hyper threading allows a single CPU core
to process two threads at one time and while this isn't quite as powerful as
just having two physical cores certainly improves performance in many
applications becoming important enough since it was originally introduced in
2002 to spread to a huge number of chips as far down as the lower-end core I3
series but get this Intel is planning to ditch hyperthreading after 22 years with
the launch of its lunar Lake and aerol Lake processors later this year why
would they get rid of what seems like such a useful feature I mean do they not
want to beat AMD a big part of this is the hybrid chip design that Intel
started rolling out with its aler L CPUs in 2021 instead of having all the cores
be basically identical team blue instead gave us P or performance cores and e or
efficiency cores especially important for laptops where battery life is a
Paramount concern and you don't want to waste energy putting processes through
more power hungry cores if you just don't need the extra performance
according to Intel current peores give you about 30% more average throughput
when hyperthreading is enabled but at the cost of a 20% increase in power
consumption and even if you're not running off a battery this can matter a
great deal in places like data centers where you're trying to move as many
threads as possible through your chips meaning power consumption becomes an
important concern and a big cost so how
is Intel trying to solve this power problem without losing that magic

world today although ecores obviously don't have the same processing muscle as
peores Intel says it's much more efficient to run extra threads on those
ecores instead of using hyperthreading on peores with the way the operating
system schedules threads it doesn't invoke hyperthreading until all cores
both P and D have been populated in order to maximize power efficiency Intel
says that by foregoing hyperthreading and instead just having more ecores you
get a 15% increase in IPC that's
instructions per clock per unit of power and a 10% IPC increase per unit of die
area hyperring is still better in terms of IPC per die area when you don't have
those additional ecores but seeing as Intel seems committed to their hybrid
chip design which also allows them to pack more cores onto their CPUs than in
the past team blue seems confident that users won't particularly Miss
hyperthreading remember that the feature was originally designed for a CPU that
had just one core Intel's benchmarks back this idea up with lunar Lake
beating the previous gen meteor Lake chips fairly comfortably despite
consuming a similar amount of power of course we'll have to wait and see what
independent benchmarks say once the chips actually hit the market but the
focus on efficiency isn't surprising considering Intel is trying to stay
ahead of the arm-based offerings from both apple and and Qualcomm which are
touting power efficiency as a major selling point but if you really do end
up missing hyperthreading it could be a great time to invest in a really high
performance sewing machine AO I'm sorry I'm sorry everyone thanks
