Advices for a new cpu + mobo + ram - probably Off Topic
 
|
Hi,
I'm a long term user of digikam, and using it for professional purpose. I need to make a new computer. Some of you may help me choosing the mother board, the cpu and the ram ?
I decided to keep hard drives (internal sata, external usb2 and usb3) and video card (MSI GT630 with 4Gb ram) from my old computer and to change the box + power, mobo + cpu + ram. I already bought a 480W power supply, and a ATX box with extra fans.
System : kubuntu last version, digikam last version, rawtherapee last version, gimp 2.8. No 3D, no game, only web and music playing but that does not count. About 250€/300$ the kit... What brand of mobo ? Which cpu ? I thought amd FX 8-cores was a good compromise, but i'm not sure. What is the difference between 970, 990X and 990FX chipsets ? My last computer was a 6Gb ram, and i never ran out of memory. I thing 8Gb is ok for this new comp. But dual-channel or not, that is the question... Thanks for your advices. Merci Gilles et toute l'équipe pour ce fabuleux logiciel ! -------------- Ultimateclem _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

As i started to plan multicore CPU support everywhere, when time permits, you can plan at least 4 core as an i5. Memory : here 16Gb, because i compute a lots of Panorama. I run also few Virtualbox for compilation stuff. So memory is important. Generally, i take always intel chipset, not especially the last one, to be sure that Linux support is optimum. Storage is very important : I use 3Tb of SATA3 (Western Digital Green). I had 12Tb in my computer (LVM) Network is 1Gb with CPL device to have everywhere that i want the home network. In my garage, i use a 12Tb NAS using Excito B3 device + HDD RAID extension (WD 3Tb hdd). I sync NAS with my computer every night for backup. A simple script using rsync is enough and very powerfull. > > > My last computer was a 6Gb ram, and i never ran out of memory. I thing 8Gb > is ok for this new comp.

I don't know mageia. Is there any deb package system like debian/ubuntu ?
Ok, intel i5 is a good idea, but which one, and wich compatible mobo ?
I forgot the use of panorama. You're right, i need more to compil/treat larges picutres. 16 Gb is best.
il will do with the hdds i have for now
NAS is a good idea too, but i don't have the money to do install that. I use external HD for backup.

Regarding which motherboard, cpu, etc, Ars Technica puts out
recommendations for building your own computer at different price points ranging from "save every penny" to "price is no object": http://arstechnica.com/gadgets/2012/12/ars-technica-system-guide-december-2012/ http://arstechnica.com/gadgets/2013/04/ars-technica-system-guide-gaming-boxes-april-2013/ The ars technica gaming boxes also make good graphics machines, with a little sensible tailoring. These days ram is comparatively cheap. So if you get 16GB, hopefully your motherboard will allow you to expand to 32GB.

Hi,
I recently build a new computer from scratch (Intel Core I7, Haswell generation, Asus mother board with Z87 chipset), so here are a few tips from that experience. 2013/8/11 ultimateclem <[hidden email]>: > I decided to keep hard drives (internal sata, external usb2 and usb3) and > video card (MSI GT630 with 4Gb ram) from my old computer and to change the > box + power, mobo + cpu + ram.

No 3D, no game, only web and music playing but that does > not count. About 250€/300$ the kit... If you go for Intel, and buy a processor from the latest generation (i.e. Haswell), be careful with the power supply. The Haswell generation introduced a new low power state with a power consumption that is so low that the power supply may shut down if not compatible. > What brand of mobo ? Which cpu ? I thought amd FX 8-cores was a good > compromise, but i'm not sure. What is the difference between 970, 990X and > 990FX chipsets ? With Intel CPUs, no need for a graphic card, there is a GPU integrated with the CPU (although not very powerful, but you ruled out 3D). A nvidia card like yours has CUDA cores, so there may be some softwares that can leverage this power (hugin does as far as I can remember, but I'm not sure about digiKam). A comparison chart is available on wikipedia for Intel processors: http://en.wikipedia.org/wiki/Haswell_%28microarchitecture%29. The mother board socket is LGA1150 for Haswell, LGA1155 for Ivy Bridge (keep that in mind for the mother board choice). You can plug a SATAII in a SATAIII slot, so a mother board with SATA III is better for future HDD upgrades (same with USB2 / USB3). I have no idea about AMD processors, and I think that they have less power than the Intel ones. Look for tests on the Internet, I'm sure you will find good comparisons between CPUs of the two brand. Mother boards will all have the same set of basic features (provided by the intel chipset). Differences may appear on the number of SATA ports, USB2/3 ports, PCIe slots, or whether there are PCI slots or not. Difference may appear also on the quality of the components (especially the capacitors), but this is something hard to evaluate from the description of the mother board, except for the price... I have the feeling that the brand of the mother board is not very important. A nice addition is a SDD. Those are cheaper now. However, it's not for data, but for the system partition to get the system more reactive (system and software loading time reduced, GUI reactivity increased, etc...) -- Benjamin. _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

The graphics chip with OpenGL and 3D should be supported out of the box. It saves some trouble on the long run if you are not forced to use any proprietary drivers. OpenGL promises faster processing with some filters "real soon now". 3D capabilities tell you something about Linux compatibility. SSD, as I understand it, is for accelerating access to often used data. I don't care if my computer takes 30s more for booting if I later spend hours on pictures. If you have enough memory on your motherboard, programs and data will be cached anyway and that access is always faster than any external drive. So check the optimum motherboard memory configuration before you buy. cu Peter _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Serial RS232 are nearly no more existent, Firewire may be of interest for old camcorders (tape ones), and video connectors are VGA, DVI, HDMI, DisplayPort and more http://en.wikipedia.org/wiki/List_of_video_connectors notice also what extension ports have the mobo.

I have enabled "Scan for new items at startup". So digiKam startup took 35 seconds on my old hdd. I moved all my photos to a new SSD (I don't keep RAWs), and now digiKam startup has been reduced to 28 seconds. ;) But as you say: Waiting a few seconds can be neglected compared to the long time editing photos. But it is faster. ;) Regards, Peter _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

But a gain of 7 seconds (35 downto 28), for a 35 seconds processing is really weak, 20%, and SSD are considerably faster than standars HDD. From a strict I/O speed point of view one can expect a factor of 2 or 3. For me, this indicates that it's not disks I/O that make the processing time. Disks I/O only contribute to the original 35 secs, the rest of the time being CPU processing, Digikam database management (SQL requests are always a highly CPU consumming processing), etc. Should that suggest that, given a hardware budget, the effort should be put on CPU power, L3 cache size, and of course larger RAM, than expensive disks ? Maybe ;) Jean-François PS: and I totaly agree on the point that when one spend 2 or 3 hours in images management, a couple of seconds is peanuts. (And more for coffee drinkers:-). Start Digikam, go get and stir your coffee, when you're back at computer, Scan for new images is done.) _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Thank you to all of you, guys. I think i will go for a amd FX8320 + Gigabyte GA-970A-DS3P + 2x8go DDR3 1600 Corsair CML16GX3M2A1600C10 For 140€, i thing this is the best value cpu. With Intel, i will only have a cpu with 2 cores/4 threads, or 4 cores/4threads... I will give amd a try. I don't thing gaming configurations are correct for picture treatment : games seem to be not multi-threaded for now. hopefully i will not have to flash a new bios on the mobo... I agree totally too on the point that when one spend 2-3 hours on pictures, seconds lost on starting are peanuts. My computer is started on monday and halted friday. No need for a SSD that will be used only once a week.

Sorry, this is of topic in digikam. On last thing. There may be a time when you want to use virtualization on your computer. You should prefer a "mainbord-bios" with this capability. For Intel you could check: http://www.intel.com/support/processors/sb/cs-030729.htm As far as I know you have the option with all AMD processors http://en.wikipedia.org/wiki/X86_virtualization cu Peter _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |
