You guys are comparing apples with oranges.
emerge -ep system will build all the dependencies of the packages in system, and that depends on the USE flags set in
/etc/make.conf

For instance, (on a core i7, 3.2GHz, desktop profile with kde and other software):

Code:

emerge -ep --nodeps system |  genlop -p

...

Estimated update time: 36 minutes.


while

Code:

emerge -ep system |  genlop -p

...

Estimated update time: 2 hours, 11 minutes.


On the first example, we are building only the system set of packages (no deps) and on the second example we also build the dependencies created by active USE flags. As we can see, emerge -ep system is not a good benchmark. I would suggest, as a minimalistic bench that tests CPU Integer and floating point ops, Memory r/w and de-alloc and multithreading:

Code:

emerge bashmark
bashmark


I will post some benchs later. If you use cpufreq, don't forget to set the 'performance' governor.

Gave bashmark a quick test as well.
For no particular reason, tried teh --detailed option as well, it is the second result which is more or less obvious. :D

Funky.
Don't know about powerful but this is the most powerful one I've yet to use Gentoo (kinda first one too, been going for weeks now never used Linux that long before).

Got Asus ENGTX275 doing them graphics,
Creative X-Fi Xtreme Gamer for sounds,
and other even less special things hehe...

Hey Chiitoo. Something's not quite right with your system (or maybe just the way the benchmark is running on your system). Same processor (running at spec GHz) here and I'm flat out stomping your system.

m/b: ASUS M4A87TD EVO
ram: Kingston KVR1333D3N9K2/8G (two kits for 16G)
sdd: Intel X25-V (where all the system binaries live)

So.. not really an extreme system. Farthest thing out there might be considered the ram. /var/log is mount on tmpfs so doing the genlop thing isn't really an option for me.

I think this system might keep me happy for a while.

Hey jathlon!


Yeah, I was actually expecting such results from someone else, or even hoping for it.
I've had a lot of weird problems indicating just that, I was indeed hoping for results for the same banchmark with the same CPU because when I first got this hardware (CPU, MOBO, MEM was replaced), I would get weird performance issues with the OS I used back then (winxP), most noticeable when several games were running at the same time.

It would result to even just the windows menus opening and moving sluggishly, this problem I did not have with my previous setup that had a dual-core AMD.
I then tried windoze7 and while I didn't exactly experience the same kind of things as under xP, I would however get bluescreen crashes a lot. Still, benchmarks like 3Dmark would produce more or less "correct" results.

I then decided to pick up Linux again and this time for realz!
I've had one lock-up while working with KDE, one time the computer had restarted while I was AFK and one time.. I can't remember what happened but I think I've had only 3 crashes with Gentoo in total.

I even contacted AMD about it back when I was running winxP and they would give me a pretty generic reply which did not help.
I can only suspect it's either the MOBO or the PSU at this time, I have my old functional PSU to try though it is only 500W I think while this one is 850W but it keeps making weird buzzing noises at times. o.o

Everything is new so you can imagine my frustration, save for the HDs and the sound-card which did not produce any problems before.
Memory I can't be sure of either but memtest did not result to any errors after running for 11 hours or so I think.
It's rather cheap'ish 1333MHz though, can't even remember the manufacturer right now...


Thanks for the results, I really appreciate it and it really does more prove to myself that there indeed is something wrong.
I have been too excited with Gentoo lately so I frankly did not care too much about the problem. :D

One more thing I thought of mentioning now is that the Gigabyte board I have was advertised to be ready for the CPU but I had to update the BIOS to get support for it and it was another task I would have not wanted to deal with since all my old CPUs are AM2 or AM2+ so they don't fit into this AM3 socket. Hoewver I managed to update the BIOS from a USB stick though it took a while to get to the Flash-utility due to the lock-upses at POST...


Also, in this thread, Phenom II X6, there might soon be more benchmarking related to this processor if you're interested. ^^

Anyways, thank you, really.
This helps!

One thing I noticed is that bashmark seems to actually utilize the CPU very little, is this normal? :S

The most it would show up using was 4% I think, that in the system monitor applet of KDE.
TOP shows a bit more as it does for all not really sure how it differs from the other monitor, does it show it for single cores or what, haven't really looked into the command yet.

Well this is pretty interesting.
Testing right now with my old PSU which is underpowered (it doesn't even have "native" PCI-e power lines and my GTX takes 2!) and I'm getting pretty much the EXACT same results for every test I run. I even tried running them while I have like 4 different games running! 4 via Wine and 1 built for Linux.
One that has 3 clients open (windows app) has some serious memory leaking going on at times even which tends to make the computer slow at times.

There is something different, though.
The whole GUI (KDE + the games) are not going into a sluggish-mode same way they went on xP and Linux with the new, more powerful PSU... so I think my doubts had some truth in them, but the CPU tests are mind-boggling, truly.
I'm going to suspect the "AM3 ready!!!123" motherboard is the next one to blame. >.>

Chiitoo, those PCI-e power cables that your GTX wants are needed for cooling... all you're doing by not using the proper power supply is damaging your graphics card.

And takes the strain off the PCIe bus.

Of course I'm not running it without power going there. 8)
If it's anything like my old card (8800), it would make a painfully loud noise if started without doing so. I don't think I ever tried / forgot the connections on this one so I don't know for sure, but I'd assume it's the same.

I have 4 different 4-pin molex connectors via 2 converters going into it so while it's not powerful enough for sure, I think it's doing fine (it seems as if the system is actually working better than with the proper PSU).
Thanks for pointing it out, though. ^^


Either way, going to post any further findings in the Phenom II X6 thread as it is more relevant.

Two hexa-core (6, w/e you call it) processors with HT?

I installed Gentoo on two Netbooks (Intel Atom N450/N280 1,66 GHz, 1GB Ram).

Now I am installing Gentoo on a Notebook (Intel Core 2 Duo 2,2GHz, 2 GB Ram) to use DistCC for the Netbook.

After nearly exactly a year from my first tests, while upgrading the Kernel, I finally decided to take a more thorough look-see to the Processor type and features section of menuconfig and Lo and behold, the results sort of hath a slightly different kind of an air around them now:

Code:
 ~ $ bashmark
#######################################################

Code:
 ~ $ bashmark -d

:MThreading u-/lock     :    :      4133:  :      +66%:


I didn't go about to test which option it was exactly that made such a drastic change concerning this particular test, though I think it is a combination of sorts, as I was able to get them lower by about 50% or so, can't remember, but I couldn't get them THAT low again. But as I mentioned, I didn't spend enough time to find out exactly. I think Tickless System had some effect at least. May bee.

I was also pleased to notice quite a change in some games, specifically some applications via Wine. The frame-rate and overall performance feels a lot better. This I would assume might have something to do with the Timer frequency setting, which was at 100 HZ, and has probably always been for me. After some reading, I tried 1000, and noted definite changes.

Might do some more testing now as it seems Portage is offering me a new Kernel once more again.

Not sure if it counts but I have a gentoo-prefix installation on my workstation at work :)

- Intel Xeon X5660 (6 cores, 2.8GHz)
- 48GB RAM
- Nvidia Tesla C2050 (because the CPU is too slow for some things :wink: )
