They might be. I do have a i7-14700 that I could use to test, but it isn't my main computer. I think that is a trucker term. Going south on I-75 from Tennessee into Georgia, the mountain is so steep that you can put it in neutral.

I did a test on my i7-12700K, and the E-cores did surprisingly well. I took my current program that uses integers, floating-point, and memory operations. First I ran a single thread on a P-core and then a single thread on an E-core. The P-core was 86% faster. Then I tested my original...

I had four HP Z420s wih 128GB of RAM each, four HP Z620s with 256GB of ram and two Xeons each, and one HP Z820 with 512GB of ram and two Xeons. And all of the Xeons were the fastest four-core Xeons of their time. Oh the fan noise, the heat, and electricity consumption!

Power use is not much of a concern with the i7-12700s I'm using now. They use a fraction of what the Xeons from about 10 years ago that I was using last year. Getting the work done quickly is the primary concern.

OK, I was thinking of rerunning the program and use the resource manager to see which cores were being used. It should put it on the P-cores. I was running 16 computationally intensive tasks with 8 hyperthreaded P-cores and 4 E-cores. Each of the threads should take about the same amount of...

Thanks. Passmark gives Skylake a single-core performance of 2291, but double that for two of them, so 4582. Passmark gives 4231 for a single core on i7-14700. When I did a test of hyperthreading years ago, it increased the throughput by 1.55x, so figure 6658 for two threads on a hypertreaded...

In an Intel CPU with performance cores and efficiency cores, suppose you are running two computationally intensive tasks, How would performance on two E-cores compare to running them hyperthreaded on one P-core?

I was using an 8TB SSD with an external USB enclosure. I want to put it in my computer to use for files. I can't get it partitioned correctly. First I tried Windows disk management and I couldn't get it to do it. I have EaseUS, and it shows: Disk 3 Basic MBR 7.28 TB 2TB partition 5.28TB...

I just tested both a cold boot and a restart, with the drive plugged in. It WAS recognized with the cold boot. On the restart, it was NOT recognized, and the computer gave a "USB device not recognized" message. I have it to do a backup late each night. Besides the restarts I have to do...

The 30-day return period has expired. But today I did a cold boot instead of a restart, and it WAS recognized.

I'm not using the Widget software. Also, I did check the driver, and it has the latest one. They are not saying that it should be recognized when the computer boots - they say to unplug it and plug it back in. But I want to have it plugged into the back permanently. Right now I have it...

Silicon Power Bolt 875, 4TB. I'm using the short cable that came with it (about 10 inches, I guess). It is plugged directly into the vomputer's USB. Right now I'm using the enclosed USB A to C adapter. I haven't checked the BIOS. Since I wrote the original message, I've tested it with four...

I recently bought an external SSD to make my nightly backups on my Windows 11 desktop computer. I leave this SSD plugged in. If the computer reboots, it says "USB device not recognized" and the drive isn't found. I have to unplug it and plug it back in to get it to be recognized. I contacted...

It could be a heat problem - they don't have heat sinks. I was copying over 1TB.

Maybe. They were also acting like a buffer got filled up and it had to wait for the buffer to be written. These were some large files, and they would be fast, then drop to almost nothing, then get fast again, repeat.
