1) Message boards : Number crunching : Dependence on the size of L3 cache on multi tread Amd and Intel CPU (Message 4162)

Noticing a dependency on the L3 cache size and CPU time with HT tasks.
More L3 cache is more important than CPU frequency.
As example: AMD chip with higher frequency and with 8 mb L3 is slower than AMD chip 16 L3 (within similar mobile architecture and generation r5 5300u/r5 7430u/r5 4600 (desktop but based on mobile chip)

Approximately 800,000,000 wu to do until project finish/end goal....
With current production rate (about 80-100 thousands per day) we will finish crunch race in 2050....

I am going to upgrade team's cluster in next two months.
I choose between add more CPU miniPC machines (i5-10400 or ryzen 5 3600) and multi 8x GPU (CH70X GTX 3070ti mining card).
Question: CPU or GPU will be better for Number Fields?

Two years ago Prescott wrote about CPU HT task time

"Hi!

I was not able to find an answer so I am posting here to ask!
I know some projects discourage Hyper-threading on CPU's for certain tasks because it makes them slower/produce bad results.
Excluding the issues from heat generation from HT, is there a problem with using HT for this project?

Best,
Prescott"

At the end of discussion Prescott summarise posts: 58% longer time on each task with HT.

My two days small experiment result is 47-100% longer task time with HT and all cores run on r5 3600, i5-10400f, r5 5300u.
