AMD CPU's: 9370 is much slower than 8350!

[skypuppy]

I have two almost identical machines, except one uses an Asus mobo and the other uses the MSI. Both run Debian Jessie Linux. The 9370 runs Debian 8.4 while the 8350 runs v8. The 9370 is CONSIDERABLY slower than the 8350. What is wrong with this picture? Psensor shows their temps to be in the safe range. Running BOINC cosmology at home, run times on the 8350 are 6-7 minutes, while on the 9370 are almost 20 hours!!! Help, please!
Both BIOS are set to optimums, but absolutely no overclocking.
Oh, and the 9370 has R9 280x, while the 8350 has GTX 960 but BOINC doesn't use either GPU.
BOINC cpu performances:
8350 9370
3,175 1,839 floats
13,000 9,000 ints

The FX-9xxx series has had a number of heat/power/stability issues, TH is full of threads on these topics.

What make/model motherboard, heatsink, and power supply does the FX-9370 use? Is the motherboard BIOS current?

Also, for clarification, what OS is your FX-8350 based system running?

AMD recommends a 1000w PSU for use with the FX-9370 (the CPU alone draws 220w). You may be under-powering the overall rig and it may be throttling itself as a result.

 

[skypuppy]

Don't need the 1000W as there is only a single video card. powersupplycalculator.net says 733 w max. but thanks. I "think" mine's an 850W. but not positive. It is at least 750W.

 

[COLGeek]

Not all PSUs are created equally, regardless of how the manufacturer rates them. We can access your system better with the actual make/model of the PSU in question.

Also, how hot is the FX-9370 getting when under load?

[skypuppy]

In this Phantek case, it will take some time as I have to partially disassemble it just to see the PSU. <sigh>
At the same time, I'm also going to try another test with the 8350 computer, loading the Jessie 8.4 version onto a temp drive and see how it compares.

 

[skypuppy]

Running all 8 processors under BOINC, it gets right to the max 135F. This liquid cooling is the bomb.

That is 57C and is the max for the CPU. It appears to be throttling from heat.

 

[skypuppy]

Oh, I forgot. That 135F was with BOINC **and** some heavy duty graphics tests (Unigine demos.) Just BOINC by itself is usually 110F with an occasional peak at 125F.

How high is the frequency of the 9370 while running boinc?

 

[COLGeek]

Understood. BTW, you are not alone in dealing with the challenges of the FX-9xxx series CPUs. AMD didn't win a lot of fans with these products. Heck, even their sponsored gamers don't use them and that is on AMD provided hardware.

I, personally, hope that Zen redeems AMD and allows them to be competitive with Intel again.

Me too. There are very few circumstances in which I can recommend AMD these days, but the Athlon 64s were legendary CPUs and I still haven't completely retired the rig with the Phenom 965 Black, which was a sweet little CPU.

if I understand the question, it's set at 4.4 in the BIOS and I assume it stays there.

Funny you should mention that. I'm still running a six core AMD 1080T that gives *better* cpu performance scores (in BOINC) than the 8350! Per CPU, that is.

100 sec slower the a i5 doing the same calculation

am3+ is what forced me to intel for my first time ever in over 15 years of amd fanboying my old 939 did a better job for what it was [those were the days ]

 

[skypuppy]

Wow. That spec is disheartening. But, like you, I haven't bought an Intel CPU since the mid 90's (for myself.)

 

[skypuppy]

Mea culpa. You guys are not going to believe this. I did the alternate tests with the OS's and discovered that Debian Jessie 8.4 with Cinnamon is the culprit!
I ran a live version of Jessie 8.3 on the 9370 machine and get the expected results in the BOINC benchmarks, 3323/second using floats and 13,898/second with ints.
I would never have guessed that an OS NEWER VERSION would cause such calamity, especially in Linux. Still disappointed that the 9370 isn't considerably faster, but it is what it is.
So now I get some egg on my face but worse, have to reinitialize that computer and reinstall everything for Jessie 8.3

It has been an interesting discussion, guys, and thanks for all the help and info.

How do I mark this one as solved?

 

[junkeymonkey]

I had the samr test under windows but I guess I lost the AMD ones or I would of posted them but its little to no difference almost the exact same results [win-7 -64]

the os Linux or windows for me and my runs was not a determining factor at all amd chips just ran out of fingers and toes
