Minisforum UM790 Pro 7940HS Mini PC



My new (mini) computer has impressed me so far. On paper, it runs five times faster than my 2017 iMac. Although certain apps, like chess-playing programs, don't run five times faster (because adding more cores does not produce a linear improvement), the computer is a multitasking beast. Not only does it have 8 processor cores, but hyperthreading gives it 16 logical cores. I have tried to slow it down by having 14 cores doing computationally intensive tasks, and the computer handles it with no problem.

This is a different experience than my 2017 iMac which would slow to a crawl if I tried to do something computationally intensive on all four cores. (I'm not sure if some of this improvement is due to Windows 11. I noticed that Windows 10 uses a lot of CPU power just for the Operating System and so far that is not the case with Windows 11.)

I've seen some evidence of thermal throttling if I push the processor, but it is not bad. The fan can get a little noisy. Hypothetically, if the same processor were in a bigger case it could have a better cooling system and maybe be overclocked.

It might be a different experience if I were gaming which is one of the features of the Ryzen 9 7940hs processor, because it has the graphics cores built into it. There is no need for a separate graphics card, which makes the computer cheaper, but it will not be as good as a $1200 to $1500 gaming computer.

I saved $60 by ordering it from Ali Express (in China), but then I had to wait five weeks for it to get here. Now the manufacturer has a Halloween sale with $60 off, but the company is also in China. However, Amazon also has it listed for $60 off.

Slow Windows 10/Minisforum UM790 Pro

Has Windows 10 gotten slower lately? I noticed the same thing with Mac OS. This could be due to security updates, which put more burden on the computer. In addition, Windows Defender sometimes runs in the background making the computer slower.

In late May I had problems with my 2017 iMac and had to reinstall MacOS and Windows 10. During the repair process, I used my somewhat slow laptop as my main computer, but I was impressed at how well it ran Windows. However, I tried the laptop the other day, and it seemed sluggish. I also noticed that the iMac was sluggish.

Fortunately, I recently bought a new mini-computer. It uses the recently released 4-nanometer AMD 7940hs processor with a whopping 8 cores and 16 threads. Compared to my other computers, it is ridiculously fast. This is also my first computer that uses SSD for storage. SSDs are very fast and have been around for a while, but they became much more affordable this year.

I waited for the computer to go on sale and ordered it from China to save money. However, I had to wait 5 weeks for it to ship from China. I just noticed that it is on sale on Amazon.

Memories

Although it is hard to know for sure, I think that my long-term memory is extremely good. I remember details from decades ago. I am astonished by the passage of time because events from the 60s, 70s, and 80s don't seem that long ago to me.

My mother passed away a week ago. I have a ton of good memories of her, and this comforts me a little.

Best wishes,

My mother's funeral was Saturday

I tried to send this email from my phone yesterday, but neither the phone nor Gmail has a record of it.  It is like the phone had a glitch and deleted the email.

My mother's funeral was on Saturday.  It went well.  

It was a fitting service for someone as nice as her.  She was a kind and caring person who I loved deeply.  I hated to see this happen to her.  

I'm coping with the loss.  Almost everyone has to deal with the death of their parents.
