Fastest single thread processor in a notebook

Post by Petermint » Sun Aug 18, 2019 3:55 am

The most time consuming applications in Linux Mint are all single thread. My SSD is fast enough to feed several threads. For my next notebook, I am looking for the maximum single thread speed processor. The i7 8565U looks like the best bet with a "turbo" speed of 4.6 GHz and a single thread rating of 2344 on cpubenchmark.net. Has anyone found a better single thread performance?

Does the single thread performance last or does the CPU immediately overheat and slow down?
Does the battery life suffer form an i7 instead of an i5?

The i5 8265U has a 3.9 GHz turbo and a single thread rating of 2136. The i5 uses from 10 watt yp to 25 watt with a "typical" usage of 15 watt. The i7 is also listed as a typical usage of 15 watt.

The price difference is $200 but the more expensive one is silver instead of blue! :shock:

Also ha e a look at the slew of amd Ryzen processors released or in the pipeline. Some have 7 nm technology,which will enable professor to run cooler. There are Intel to Amd comparisons on line too.

I looked at Ryzen notebooks. Based on current models, the prices may be lower but the maximum single thread speed is lower. Some of the Intel based ultrabooks are dropping in price, including the ones with high single thread speeds.

What is not improving is the range of SSD. A decent size SSD is still artificially high. I will probably buy the fastest processor with the smallest disk then install my own SSD.

Yes, CPU throttling is a real issue on i7/i9 on many laptops especially the thin and light. MacBook Pro CPU throttling issue is a recent case of this problem. May not be as big an issue with single core CPU depending on the thermal management design of the laptop.

Yes, battery life is shorter if you draw more power.

The question you must answer is, is $200 worth the possible 10% performance increase? Unless that is, you must have that silver colour :wink:

Rather than raw speed , you can choice the test that is most appropriat for your tasks.Say May be Math etc, tere are so many on the net. A processor with lower speed may give a higher throughput.

Silver looks a bit like a tired old Apple notebook I had to use on one project. Painful. It takes the shine off the silver.

The blue notebook looks more distinctive than the silver. The blue machine would be 2.5 times faster than my current machine while the silver one is 3 times faster. What would be nice is a Ferrari red notebook that is 4 times faster or a Bugatti grey that is 5 times faster or a Koenigsegg black that is 6 times faster. :evil:

Need some racing stripes to make it even faster :wink:

I started looking at upgrading one of my desktops for the type of work that runs slowwww.

The best cost per unit of speed is the Ryzen 5 3600 and it misses out on top speed for multiple threads.
The next price/speed is Ryzen 7 3600X but you do not gain much.
For absolute fastest single thread, The Ryzen 7 3800X wins and provides a big step up in all thread speed. Just $200 to get about 5.7% extra single speed and 22.9% extra all thread speed.

The Ryzens need a graphics card and I can find only one without a screaming fan. The next challenge is to find the fastest quiet graphics card. :?

For silent desktop, you can get water cooling for both cpu and graphic card plus some nice quite large capacity case fan for the HDD.
