thank you for your response. Is there a comparison of 5th gen CPU idle power consumptions? I think the differences may be very low, but It would be very nice for me to see measured values instead of something like (TDP: 45W). Thats not enough information for me.
For gen5 CPUs was declared 23W max power in C1/E state. Although the 5th gen consists from only 4C CPUs, so we have no data for lower core counts. Measured values of CPU only power are not available, there are measures of whole systems, check the http://techreport.com/ reviews for example.
Thanks for the response! I wasn't aware of the absence of 5th gen i3 desktop processors. However, I think the i3 6100-6300 or i3 6100T-6300T are the ones that fit my needs the most. I was asking for measurements - that would have been the ideal case, but since the processors are pretty new, I guess there is not so much practical information available yet. I would be satisfied already, if I could get a little more information about the i3, which I couldnt really find on the internet (at least I'm not very confident about the answers I have found so far).
1.) Is the idle power consumption of i.e. i3-6100 and i3-6100T (T - vs. non-T versions in general) different? If so, by how much?
2.) Is the estimated idle power consumption of i3-6100 or 6300 somewhere around 5W?
The reason for this thread is, that I want a low power consumption in idle and I've read somewhere, that some 4th gen i3 need 25W in idle and in some other forum I've read, that the idle power consumption of current intel desktop CPU's is < 5W throughout all models (i3, i3T, i5, i5T, i7, i7T). If someone in this forum has a very high confidence (or has already measured it or seen some measurements on the web), that the i3-6300 (or 6100) requires less than 5W or similar in idle, I'm going to buy it asap. If not, I will take a closer look at the i3-6100T.
Thank you for your contributions.
Is the idle power consumption of i.e. i3-6100 and i3-6100T (T - vs. non-T versions in general) different?
Probably yes, for 4-gen CPUs for low-power (like T) SKUs, max C1/E values was lower by 5-7 W comparing with base models.
Thank you! Thats too bad. I hope they are almost identical for 6th gen i3 CPUs.
I've been trying to find this exact information! How do Skylake processors compare in power consumption in idle states? Would there be any difference between Core and Xeon e3-1200 v5 processors in idle power consumption?
Any new information on this? If the idle power consumption would be the same it wouldn't less matter if it is a T model or not. Which one did you buy? What are you results?
The following system consumes 12-14 watt on idle and under light load:
cpu: Intel i7-6700t
motherboard: Supermicro x11ssz-qf
ram: Crucial DDR4 2133 CT8G4DFD8213
ssd: Samsung 850 Evo
psu: SeaSonic SS-400FL2
cpu cooler: Intel E97379 0.17A Foxconn
Thank you for contacting Intel Communities.
I understand that you would like to get the power consumption for some processors.
A chart for the power used in the different states of the processor (idle, full load, etc) is not available right now.
This is because depending on the usage the processor is needing, the power consumption is needed.
Now, in order to better understand the power management for the processors, my recommendation would be to check the datasheet for the processor.
Here you can find this information for Skylake or 6th Gen processors:
Also, Intel has some applications that can monitor the power usage.
Esteban, is there a reason for exclusion from datasheet of 6rd gen Cores TDP values for C1E state (Table 5.3)? Most systems never reach deeper states for whole their productive life, so C1E value is a practical knowledge needed for system power planning.
It seems that idle processor consumption is the SAME for all Skylake i7 chips: 14w.
Above I listed my test system with 6700T processor. In this article [ Coding Horror, To ECC or Not To ECC ] an identical system but with 6700K processor is documented to have the same idle power consumption. I would have gone with a regular chip (6700 or 6700k), had I had this information earlier.
On the linked blog I only saw a 6100T with 10W power consumption in idle state (but for the complete system). It seems that there isn't a big difference between the 6100T, 6500T and 6700T. Taken your system as base you can say +2W for each higher class CPU.
You are saying that the regular versions (TDP 65W+) are having a similar power consumption in idle state? I only read in an article of tomshardware, that the 6700K only needs 5W in idle state (but only the CPU). What sense does the T models make except a higher price and lower power? Yes, under load you have a lower power consumption, but also reduced CPU power compared to the regular models. If the CPU has finished it can go faster into idle state. What advantages does the T models still have?
