Let this be a lesson to all you. The Fujitsu Q702 I am testing at the moment has a 1.8Ghz Core i5 CPU with Turbo Increase Technology which may take it to 2.6Ghz. The complete thing is packed inside a pill PC. Impressive. The condition is the fact that this 1.8Ghz platform down-clocks itself from 1.8Ghz  to a typical 1.3Ghz whenever below load. Fujitsu don’t appear to be telling their shoppers either.

Fujitsu have taken control of the energy found on the Stylistic Q702 crossbreed inside purchase to stop it overheating plus it signifies which rather of the guaranteed minimal nominal clock speed you’ll receive regarding 1.3Ghz average clock rate below load. That’s almost 50% less processing force than the number one designs found on the same processor but Fujitsu fails to point this out about their site.

Advertising a 1.8Ghz-2.6Ghz CPU plus then restricting which to really brief length function is somewhat misleading for me.

The Q702 is probably to have been fashioned with what’s well-known as configurable TDP (cTDP) that enables the designer to set the CPU to a lower energy profile, effectively locking out any long-term high-clockrate CPU or GPU inside purchase to keep thermals beneath control. Fujitsu have their backs covered naturally considering the CPU may indeed momentarily speed-up above the nominal 1.8Ghz before it instantly drops right down to sub 1.8Ghz degrees. 1.3Ghz is regarding the average clockrate I’ve watched below any CPU plenty. For the record, I have seeen short moments of 2.6Ghz clockrate.

I tested Cinebench 11.5 plus got scores of 1.63, 1.4 plus 1.57 because results.  For comparison, the Lenovo Twist, at half the cost, turns inside a 2.33 score.

It’s not only the Q702 which does this; The Acer W700 does a synonymous trick according to forum reports. You’re probably to find this about different Core pills too. As predicted, it’s confusing for consumers.

It doesn’t merely stop at pills either. The Samsung Series 5 Ultrabook has Turbo Increase locked-out below power energy though at smallest which 1 could maintain the nominal clockrate.

There are a couple of interesting points to note regarding the Q702 though. Firstly, I utilized it for a full function task when at MWC last week plus I didn’t see this problem – A reader pointed it out to me. My high-load jobs were utilizing Intel Quick-Sync Video though thus perhaps that’s not affected because difficult because the CPU is. Secondly, by keeping the clock low you’re capping the energy use found on the CPU that causes longer power run-times plus, inside theory, a cooler plus better program. The Fujitsu Q702 absolutely has certain wonderful power lifetime figures.

The moral of the story here is the fact that when you’re searching at really tiny plus tight Core-based designs inside 2013, you ought to be aware of thermal restrictions. All Ultrabooks might differ their Turbo Increase according to temperature thus that’s to be expected. Many might turn of Turbo beneath power energy as well as the Fujitsu Q702 TabletPC (it’s not an Ultrabook) features the extremes where clocks are reduced under nominal, plus expected speeds.

Thank goodness for independent ratings plus wise comments! Thx DaDude!
