Let this be a lesson to all you. The Fujitsu Q702 I am testing now has a 1.8Ghz Core i5 CPU with Turbo Increase Technology which may take it to 2.6Ghz. The entire 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 consumers either.
Fujitsu have taken control of the energy found on thecrossbreed 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 energy than the greatest designs found on the same processor but Fujitsu fails to point this out about their url.
Advertising a 1.8Ghz-2.6Ghz CPU plus then restricting which to truly brief length function is somewhat misleading for me.
The Q702 is probably to have been made with what’s recognised as configurable TDP (cTDP) that enables the designer to set the CPU to a lower force profile, effectively locking out any long-term high-clockrate CPU or GPU inside purchase to keep thermals below control. Fujitsu have their backs covered naturally considering the CPU usually indeed momentarily speed-up above the nominal 1.8Ghz before it promptly 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.
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 clients.
It doesn’t only stop at pills either. TheUltrabook has Turbo Increase locked-out beneath power force though at smallest which 1 will 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 procedure whilst 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 possibly 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 several amazing power existence figures.
The moral of the story here is the fact that when you’re lookin at surprisingly little plus tight Core-based designs inside 2013, you ought to be aware of thermal restrictions. All Ultrabooks may fluctuate their Turbo Increase according to temperature thus that’s to be expected. Many may turn of Turbo beneath power force 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 reports plus wise comments! Thx DaDude!
