Pc for calculations

[radge]

Hello, I need a PC to do mathematical calculations, it will run a win10 with a multi-thread program that uses CPU in the first place and RAM in the second place.

I put 32gb of ram which is a lot I won't use them... I could go down to 16gb

I look forward to your suggestions and comments!!!

Hello,

For now I'll tell you the power supplies I would choose, and then the rest of the team can come and recommend more things

Seasonic M12II-620 EVO 620W 80 Plus Bronze Modular Power Supply

Corsair CX600M 600W 80 Plus Bronze Modular Power Supply

Best regards!

Program?

Budget?

If the application benefits from multithreading forget about a quadcore… a 5820K is more powerful than that 6700K in series.

If you overclock it a little bit you deserve that Skylake.

We must differentiate between what is good for gaming or tasks that do not take advantage of more than 2 or 4 cores and those programs or multithreaded tasks that benefit from many cores (rendering, video compression, brute force calculation...)

As for the power supply I agree to avoid that Antec and get a Corsair or Seasonic.

As for the cooler both if you keep the 6700K and if you go for a 5820K put a more powerful one although that already depends on the budget.

@Espinetenbolas:

¿Programa?

¿Presupuesto?

Dos datos fundamentales.

Just in case my experience is of any use, in my case I work with Matlab and they have given me a dual Xeon E5 v3 (16 physical cores in total) with 64Gb of RAM and two Quadro K3000. Of the 16 cores I rarely use more than 3 or 4 but I have run out of RAM a couple of times. Needless to say, the Quadros have been money thrown away.

Ok thanks, my question is why do I need so many W if it doesn't have an external graphics card.
The truth is that it's a proprietary brute force calculation program.

Thanks!!!

Thanks, the issue of RAM with 8gb of RAM would be more than enough if I get 16gb or 32gb it's to already have them…

Thanks, I don't know much about micros... if you can tell me 2 or 3 that you think are convenient so I can look at the price and compare.

By the way, is it worth going for a team with DDR4 or getting a better micro but with DDR3.

Thanks,

For efficiency, quality, stability, reliability… And if in the end you put a K micro and overclock it, then with much more reason :sisi:

Greetings!

Ok thanks I understand…

As for micro you can recommend me one, in principle maximum budget for the micro between 300 and 500€ I do not rule out doing overclock …

[radge]

Hello, I have made another configuration, I have removed some RAM and improved the font and I think the micro.
Let me know what you think?

[Espinetenbolas]

The 6700K's floating-point unit is more powerful at the same clock speed than the 4790K... but the 4790K has more MHz... in the end you end up the same unless you have specific applications or use of instructions.

Also, the speed of the RAM plays its role.

That's why the program you use is important because if it takes advantage of multi-core, a 5820K is much better.

Although of course, the motherboard is also more expensive and you need to buy a dedicated graphics card for this platform.

I'm almost more interested in it having the integrated graphics since putting an external one is a device in my case "useless" in addition to 20 or 30€ of expense.

No?

Thanks

It depends on the program. A powerful GPU can do a great job with parallelizable calculations.

The program must be secret :troll:, and that is the most determining factor.

Well, you never know, it could be a multithreaded program that can take advantage of the graphics, and that would multiply the capacity.
But that depends on each program, just as the graphics could be a superfluous expense, or it could increase your performance per euro a lot, the program is the fundamental thing in this case.

Salu2.

Hello, I think I explained it above.
The program is made by me, written in Visual Studio with multi-thread and what it does is data combination, something similar to the pools…but for another sector

[defaultuser]

Ok, Well, it seems like I didn't see it.
Apparently c++ can use CUDA, I would seriously consider it.
Well, you could add the graphics later if you see that you can take advantage of it, it's not urgent, but it could be several times faster if that's the case.

Regards.

[Espinetenbolas]

So then a GPU with CUDA is 50 times better than getting a 6700K

I second what Espinete says. For high-frequency trading I have read that Tesla gives good results.

@defaultuser:

Ok, Pues se ve que no lo vi.
Por lo visto c++ si puede usar CUDA, yo me lo miraria muy seriamente.
Bueno la grafica podrias añadirla mas tarde si ves que la puedes aprovechar tampoco es urgente, pero te podria ir varias veces mas rapido si fuera el caso.

Salu2.

Si si conozco CUDA pero no es viable ja que este programa depende de un SDK de un tercero y no puede funcionar con CUDA por el momento.

Gracias
