1) Message boards : Number crunching : What can we expect from Zen 2/Ryzen 3000? (Message 131060)
Posted 226 days ago by Profile DeleteNullProject donor
Both have hyperthreading, 7700K = 8 threads, 3700x = 2 x 8 threads.
Depending on the FFT length sometimes the 7700k has shorter times sometimes the 3700x.

But the 3700x calculates 2 WU in parallel when the 7700k is doing (only) one.......


This thing is pretty fast. A first test with LLR-PPS-MEGA shows (on average):
2 times faster than 7700k (memory 3000)


I checked your very interesting tests and found that Ryzen 7 3700X is twice as fast as Ryzen 7 1700X but is not faster than Intel i7-7700K...???

Intel i7-7700K, 800 sec
primegrid_llr -d -oDiskWriteTime=1 -oThreadsPerTest=4 llr.in
Using all-complex FMA3 FFT length 256K, Pass1=128, Pass2=2K, clm=2, 4 threads, a = 3

Ryzen 7 3700X, 982 sec
primegrid_llr -d -oDiskWriteTime=1 -oThreadsPerTest=8 llr.in
Using all-complex FMA3 FFT length 256K, Pass1=1K, Pass2=256, clm=1, 8 threads, a = 3

A new Ryzen 3700x (TDP 65W) arrived today together with a x570 board and DDR4 memory 3200.

This thing is pretty fast. A first test with LLR-PPS-MEGA shows (on average):
2 times faster than 7700k (memory 3000)
A bit faster (~ 10%) than 7820x (memory 3000 quad channel, AVX 512)

7nm vs. 14nm: 3 times more energy efficient in LLR.

It's also cheaper and you can use the (very good) fan that was included.
(default settings, memory with XMP profile #1)

Impressive.
Did anyone already reach the next level of all bronze shields?


Thanks. And yes, e.g. Scott Brown.

all active subprojects Emerald or better.

Thank you Robish!

The only thing that is undone is the upgrade of my M-Badge.
But this must be another thread ;)

This (3 days ago), and
that (today)

One more to complete this level.
7) Message boards : Generalized Fermat Prime Search : GFN-16 MEGA Prime Search starts March, 14, 2019 (Message 127995)

Hello Doctor,

I am using (8x8 threads, cc_config with 8 ncpus):
<app_config>
<app>
<name>gfn16_mega</name>
<fraction_done_exact/>
<max_concurrent>8</max_concurrent>
</app>
<app_version>
<app_name>gfn16_mega</app_name>
<cmdline>-t 8</cmdline>
<avg_ncpus>1</avg_ncpus>
<max_ncpus>1</max_ncpus>
</app_version>
</app_config>

This works fine for me.

I am getting only this:

Thank you Robish!

For the upcoming challenge most of my boxes will do only CPU work, and after this.....GFN-19. So, 4 MEGA's within a month is an exception ;) No one has to take care about me.
