Observations Moving from i7 7700k to i9 10900k

[regis9 4,013]

Now that my new build is up and running I thought I'd post my initial observations:

- As a quick and dirty OC, I used the ASUS built in AI overclock tool.  It set me at 5.1 on all cores

- In MSFS the recommendation is now for Ultra preset, up from high

- On ultra I did three test flights:

- ORBX KORS: FPS were in the high 60's and smooth.  Previously on high I was getting high 50's low 60's smooth

- CYTZ/Downtown Toronto: FPS were in the mid 40's to low 50's, smooth

- Torture test time, KLGA and overflying Manhattan: FPS were low 40's and smooth.

CPU temps were in the mid 50's, "CPU Package" Temps were 67-68.  I'm not sure what the difference is between these two or which I should be paying attention to?

Overall I'm quite happy with the boost in performance I've gotten through this upgrade.  It does seem like I may have a bit more headroom for an additional overclock so perhaps I've done well in the silicon lottery.

Now time to go fire up the FSLabs A320 at Toronto Pearson and see how that performs.

CPU temps are your core temps. CPU Package Temp is the temp of the lid of the CPU where it interfaces with the CPU cooler. The important numbers are the CPU core temps.

"CPU temps are your core temps."

No... CPU temp is either a sensor on the motherboard, often inside the actual socket, or from a CPU internal Digital Thermal Sensor. 

 

"CPU Package Temp is the temp of the lid of the CPU where it interfaces with the CPU cooler."

No... Package Temp is an average value of the hottest sensor in the entire CPU package. 

You are getting mixed up with "TCase" which is the temperature at the Integrated Heat Spreader.

 

Core temps are indeed the temps to be concerned with. And if you use a software like RealTemp or CoreTemp or Hardware Monitor the core temps will be labelled as that. 

There are numerous sensors in a CPU.

Don't pay attention to "CPU Temp" Pay attention to each individual core temp which can be measured in software like RealTemp, CoreTemp, Hardware info, Hardware Monitor.

Asus Software usually tells you "TCase" which is usually lower than the individual core temperatures. So important top look at the temperature of each core. In addition, look at TJ Max. TJ Max is the maximum temp before the CPU starts to throttle back and ultimately shut down to avoid damage. 

I use RealTemp and HW Monitor.

Thanks!

I too upgraded to i9-10900 CPU it has 10 cores with HT. 

My old system had win 7 and I could see how each thread is being used....

like this 

How do I see that in Win 10. Core by core, thread by thread the utilization?

Thanks

In Task Manager open tab performance then at the bottom open Resource Monitor.

I have to select "Logical processors"  too.

0-19 cores, Core 19 is being used the most. Hmmm...

I think it's important to pay attention to the terminology w/r/t cores and logical processors.

A "core" is a physical processing unit. 

The 10900K has 10 cores, and those function as 10-20 logical processing units (LPs), with two LPs per HT-enabled physical core and one per HT-disabled core.

Also, the performance display does not show threads, it shows LP utilization.  There are usually hundreds of program threads running and being swapped in and out across the various LPs at any given time.
