Intel Core i7 In Detail - Hyper-Threading and Turbo Boost - TechAmok
Intel Core i7 In Detail - Hyper-Threading and Turbo Boost - [hardware] 05:15 PM EST - Feb,02 2009 - post a comment iXBT
Labs take a further look at the Core i7 performance in the 'minimalistic'
mode (without Turbo Boost and Hyper-Threading), with only Hyper-Threading
enabled, and with only Turbo Boost enabled. And, of course, they also compare
the results to the nominal mode (both are enabled). Here's a taster:
Turbo Boost technology demonstrates impressive performance gains practically
everywhere. On the one hand, it's not bad: "common overclocking" provides
performance gains to all users without exception, no consequences to system
stability (at least according to the manufacturer). On the other hand,
overclockers lose their semi-legal ways to get higher performance for less
money, as manufacturers take advantage of their favorite tricks. However, it was
easy to predict the appearance of something like Turbo Boost: any popular
semi-legal practice always attracts manufacturers who want to benefit even by
such tricks.
Despite its new reincarnation, Hyper-Threading is still as controversial as
in times of NetBurst. This technology yields zero performance gains
according to our overall score (rounded), even though some tests demonstrate
significant performance gains or drops. The reasons are lying on the surface:
it's not easy to optimize software for virtual multiprocessing. What concerns
Intel, this company abandoned this field, having rolled out truly multi-core
processors -- and software developers immediately followed suit. To all
appearances, Hyper-Threading is being revived now. However, developers already
accumulated negative experience -- HT had been actively advertised at first, and
then it was forgotten because of more popular market tendencies. So those
developers, who have already mastered this technology in its first
reincarnation, will hardly welcome the revival of HT.
Our today's analysis once again proved the main conclusion from our Intel
Core i7
review: it's a "no-nonsense" processor. Candid performance drops of Core
i7 caused by the reanimated Hyper-Threading are smoothed over by Turbo Boost in
most cases. As a result, the overall impression from its performance in the
nominal mode is moderately positive (few users want to know details, like our
today's tests). Time will pass, and they may get used to Hyper-Threading and
learn to program software that at least won't suffer from this technology, or
even will benefit from it -- we already have positive examples. Intel seems to
have reached perfection in broadcasting positive thinking attitude to potential
users: it does not grab and haul them into its concept of radiant future
(farewell, Rambus), it just pushes them mildly in the right direction.
