processor for solid edge: quad or dual??? ?

[migale]

hi to all, I had already opened a time ago a similar discussion but now it seems to me that things are a little more evolved regarding the quad-cores so I wonder if it still agrees to opt for a powerful dual-core rather than for the most modern quads to exploit a software like solid edge v20.

the speech is the usual, I find myself having to choose a desktop pc and obviously the processor is the first choice to make. What do you recommend me among these intels?

- q6700
- q8400.
- q9400.
- E8400.
- e8600

Thank you all!

I would say what offers the highest performance and that obviously costs more!
It seems obvious.

depends on what you have to do... all if they could take the pc to the last cry: eek: but as you know, performance is paid. if you do not exploit dualcore
But this does not mean that the next releases do not.

rather seeks a good compromise between processor/ram and sk video to get a machine adapted to your design needs, because then
It is useless to buy a ferrari and put us on the tires of a 500.

It also assesses whether you will only use it on PC if or even other calculation prg that I know about it type femap etc. that then take advantage of the double processor.

I do not remember where, but I had read that there are considerable difficulties for programmers to exploit multicores for solid modeling.
Is there someone who can explain this better?

Hi.

not all processes are adaptable to multi core, and the reason is very simple. For example, we have to do 100 operations, with 2 cpus, we have to think that it puts us half the time compared to 1 cpu. This is not always true, if the parameters of each operation depend on the previous one, go to itself that I must wait for it to be calculated to pass to the sucessive one. therefore having 1, 2, 100 cpu does not speed the calculation. because operations can only be done in sequence and not parallel.

Thank you very much!

having two or more cores can be useful to open two instances of if, one to make a table and one to model for example.
It is clear that it is not very frequent cases so that it is necessary to consider whether it is more expensive or business. in everyday modeling work you usually spend a lot more time thinking about what to design rather than waiting for the pc to perform commands, except of course special cases of very complex modeling: fusions of bases of diesel engines, toothed wheels with 500 teeth, etc.

 

[migale]

Thank you all, but ultimately a dual-core high frequency (e.g. e8600) is still to be preferred to quad-cores that have lower frequencies?

 

[cacciatorino]

depends on what work you have to do!
if besides designing you also do fem analysis and development of cam paths, maybe the quad core is better. If you do nothing but model it's okay with dual.
I'd put the money in your place for more rams or a more powerful video card.

only modeling... So I'm going to one between 8400 and 8600.

on ram, using xp, advice to put more than 3gb (would you not see all from the operating system)?

 

[maxopus]

In my opinion, yes, I do not think that there is a need to manage 4 or 8 processes in parallel.

Surely yes, so long a two years we will all be 64 bit and now the ram costs very little.

Listen a bit, I would have proposed a workstation of the processor intel xeon w3503 to 2.4ghz and 4gb of ram ddr3 to 1066mhz (in addition to a picture fx 580 as graphics card).

according to you it is worth spending about 40% more than a "simple" pc equipped with an e8600 and 4gb of ram ddr2 800mhz or the performance (at equal video card) will be comparable?

Thank you very much to all, you are very kind! :finger:

I know that with big assemblies the processor is important, as well as ram and frequency.
depends on you: if you predict big asses better what costs more because it will allow you to twist your thumbs for a short time (while you wait for him to work).

Hi.

So would you opt for a workstation like the one they offered me?

 

[alex64]

...according to me you should spend the difference that rightly said you were 40% more, putting it in the video card, and buying a assembled with branded components, in the end you spend the same money but the graphics will not compare.
With regard to the processor, if you don't need to make calculations pushed a dual core is more than good.

pro of assemblies:
equal performance costs less
components are definitely of common use so you will have no problems in case of replacement (remember the motherboard of a pii of the with out standard fixing holes).

pro of brand pcs:
buy and work
the guarantee of assistance within 24 hours from the fault (for at least, I also believe the competition).

Then choose you, typically branded pcs are slightly slower to have more reliability. I always bought assembled except for the laptop obviously.

thank you but no one has yet clarified where the xeon w3503 processor is placed compared to an e8600. appearance of delucidations. . .

hi, for personal and direct experience I can tell you that a dual core, at equal clock, is more performing than a quad core, in the daily use of solid edge, and I can also write that the performance you notice also to "eye".

 

[Onda]

I use an i7 920 core and is extremely superior to the core2 series. although its clock speed is 2.66ghz. when using only one core (as with cad programs) has an internal multiplier that raises its frequency of two steps. I think it arrives at 3.33 on the single core. its architecture with the built-in memory controller is extremely superior in cad and fem use compared to core2.
It also directs 3 memory channels (6 benches) so you can start with 3*2gb and upgrade in the future to 6*2gb at a very low cost. Among other things, the motherboard uses the socket of the next generation of processors, so an upgrade is easier.
I use solid works and not solid edge, but I think the issues are similar.
in the company I compared it to other machines with processors of the 8000 series and the performance of regeneration is clearly superior.
I hope I've been helpful
