Latitude 7370

I've seen no annoying changes in the display brightness but I have turned off the adaptive brightness in the power plan. However, I should note that while Dell's specs indicate 400 nit brightness I think it is nearer 300 nits - my Samsung NP900X3B (also rated at 400 nits) is definitely brighter. However, it's plenty bright enough unless used in sunlight (when 400 nits isn't bright enough either). Furthermore, high brightness when running on battery will also significantly reduce the battery time. The 7370 has a power drain difference between minimum and maximum brightness of about 1.5W whereas on the NP900X3B it is about 4W.

Thank you. That's reassuring. I'd rather go with the FHD due to better battery and less glare.

I'm not sure whether to go with M5/8gb or M7/16gb ram.

Would anyone mind who has either the M5 or M7 models to install the "Intel Extreme Tuning Utility" and a take a screenshot of the "Advanced Tuning" tab? I'm interested to see what TDP settings are being used.

Thanks

 

Here's what XTU says about my m5-6Y54. What does it tell you? The bursts of CPU activity are 5 runs of wPrime 32M.



Perhaps this graph will also be of interest? The CPU core power (as reported by HWiNFO) is at around 10W for 15 seconds before dropping to 4.5W. The 16GB RAM option would be more future-proof although 8GB should be enough for the likely usage appropriate for the notebook.



The peak CPU temperature I have seen is about 65C while the sustained CPU temperature during wPrime 1024M is around 55C.

Thanks John.

I think earlier bios versions had the "Turbo Boost Power Max" set to 4.5W and the "Turbo Boost Power Time Window" set to 1 second. So it's good that they have now been changed.

The graph is interesting. It would be very interesting to see how the M7 performs in comparison, and possibly over a longer time period.

I was trying to make a comparison between these machines and the Surface Pro 4 M3 and the Macbook M3/M5/M7 range.

This is a review of the Macbook M3
http://www.notebookcheck.net/Apple-MacBook-12-Early-2016-1-1-GHz-Review.164797.0.html

On the Cinebench 11.5 multi-core test (different OS and benchmark) it can hold 2Ghz during the first test which lasts an estimated 1m30s. It heats up to 80 degrees. So it looks as if the Macbook M3 can maintain a higher clock and wattage for longer, however it gets quite a bit warmer.

I wonder how much extra potential there is in the Dell. Could the "Turbo Boost Power Max" be set to 6W. I suppose for most people the potential extra performance wouldn't really be noticeable in every day tasks.

 

Hi John,

I have a 7370 with me and I messed the Intel Graphics settings. Can you please give me screenshots of the default settings that came with the notebook?

My colors are too washed and its driving me crazy as I dont know how to set it back to the default values.

Thanks!

 

Is this what you are wanting?

If not, you will have to tell me where to look.

John

 

Yes that was exactly I was looking for, I really appreciate the help. I asked the same question in dell forums in the dell site and the answer I got was to format the system

How is the battery life and heat on your system? Mine gets really warm.

I commented on the CPU temperature here. I did a temperature test by checking the external temperatures using an infrared thermometer after 3 consecutive runs of wPrime 1024M and the highest external temperatures were 37°C on the keyboard and 42°C on the bottom. I find these quite acceptable and no hotter than other notebooks with fans. In addition, the ridges on the bottom mean that, if the notebook is on lap / legs / knees then the hottest part on the bottom isn't in contact with any skin.

The battery life isn't as good as I had hoped but getting more from the relatively small battery feeding a reasnably big display is a challenge.Under very low usage with a reasonably dim display the system power drain can be around 3W but under moderate usage the system power drain can be 6W or more. Assume 30Whr effective battery capacity and divide by the power drain. eg 30/7.5 = 4 hours, 30/6 = 5 hours, 30/5 = 6 hours. Use BatteryInfoView to show the instantanous power drain and see for yourself what affects it. Anything (other than the PSU) plugged into USB-C adds about 3W to the power drain as Intel seem to have forgotten to apply the impressive power management which they have on the CPU. The 43Whr battery potentially increases the battery time by nearly 25% but it isn't compatible with security features such as the smartcard reader as they compete for the same space under the palmrest.

Thanks for the info I read about the external battery. I find it a bit slow when using Firefox , chrome seems ok but drains battery a lot. I bought this for browsing the web and I can't complain for the price I got it.

Any other settings that you are aware of to increase the performance?

Cut down on the unneccessary baggage that tries to hitch a lift on the web browsing. Use the FlashBlock and AdBlock Plus add-ons and a custom hosts file.

The Dell Power Companion is one way to increase the time away from the mains socket. I'm on the lookout for alternative USB-C powerbanks which may be compatible. I think they will need to offer a 20V output at a minimum 0f 1.5A (ie 30W). I have successfully used a 30W (20V @ 1.5A) AC adapter without it blowing up. One disadvantage, however, of using a power bank while the computer is running is that it will think it's plugged into the mains and not utilise any power saving features. It's therefore better to use the power banks to top up the internal battery when the computer isn't running but you are away from a mains power socket.
