[SOLVED] Turbo boost not to extend intel claims

[SeverinV]

So i have i5-4460 . According to intel it should boost to 3.4 but when i have boost frequency set to 100% it only boost to 3,27 / 3,26/ 3,25 .
So is something with my cpu/ motherboard ?
Thanks for the help,
Cheers,

turbo only works under specific conditions, it isn't guaranteed.
PC needs to be cool enough and have enough power to run 1 core at that speed.

If you set the number of cores to one in the BIOS and run the Intel® Processor Identification Utility, it shows the highest Turbo Boost frequency. Make sure you reset the switch in the BIOS to reactivate all cores.

Make and model of your motherboard? BIOS version for said motherboard model? What are the temps in your case when you see that the turbo boost doesn't go to Intel's claimed frequency? To add, Intel's Turbo boost is an advertised feature if and when the system/platform needs it. Often times, it doesn't.

asrock h87 fatality . The latest bios update. Core cpu temperatures are from 52 to 56 when on load when so called boost is active. Motherboard is around 40 degrees .

So if i buy i5-10400f it wouldn't really boost to 4.3 as said at official page ?
Considered all that what is the average boost on intel cpu's ? Is it usually 70% or 50% of the advertised boost ?

it depends on the circumstances, if its anything like precision boost on AMD there are a number of factors that all have to line up for you to get the boost. I believe newer Intel cpu can boost more than 1 core now.

Availability and frequency upside of Intel® Turbo Boost Technology 2.0 state depends upon a number of factors including, but not limited to, the following:

• Type of workload
• Number of active cores
• Estimated current consumption
• Estimated power consumption
• Processor temperature

I believe newer ones use Turbo Boost 3 now, 4 core boost

So to get higher frequency overall should i get 10100f or 10400f ? One is 4core4thread , second one is 6cores12threads. First one has 3,6 base clock and second has 2,9 base. So in games that use up to 4 core max, because it has the boost it should reach that 3,6 clock and in newertitles it should perform better because games can use now 6 core and more .

I don't think you will find Turbo works in games, due to heat of other parts in PC raising ambient temperatures.

the 10100f is 4 cores/8 threads. Not that far behind.
6 core only wins in some areas cause it has more cores.
I would get the I5 only as more games like more cores now. But I can't tell you what to do.

I think your still not understanding boost speeds. You have a single core boost speed and a all core boost speed.
10100 and 10400f
