I have an important computer build coming up.
    #22298649 - 09/27/15 01:40 PM (8 years, 4 months ago)

I had just finished one rack portable rack-mount system for my studio--a Xeon e3-1231 v3 proc--when my main system crashed, and instead of replacing it I am going to set up a multi-core system in a big server case.

it is for music production, editing, etc.  so the design goals are low heat, low noise, stability, and ability to run a lot of threads and render simultaneously. In addition, audio processing requires more cores.

Right now i was looking at the new i7's i7-5775c and i7-6600k and both have good features for audio rendering (especially the i7-5775c) but it uses only ddr3-2300.  Both are only 4 cores.  So I am probably going to go to the xeon haswell E5's or the haswell i7-58xx series 6/8 cores.  The haswells don't 'look' as good on benchmarks, but they generate less heat and have more cores for the money.  I need lots of I/O so i am pondering which to buy.    right now my top would be xeon E5-2660 v3 (10 core) i7-5960x (8) xeon e5-2640 v3 8c.  6 cores i7-5820 or e5-2620 v3. 

or maybe i do go with a i7-5775.  remember, I am not gaming, Im going to use an nvidia Quadro workstation card with no fan.  Any ideas?

Why are you worried about noise?

Can't you just get a high-end external sound card?

I would think that should be better anyway, since they are designed for this.

With regard to the processor, I'm sure the instruction set utilized doesn't change...

I'm not a hardware guy but generally I just look at the specs.

Instruction per second, cache, number of cores, etc.

I'm sure the Xeon's or another processor made for a server can take more of a beating tho.

A sound dampening case like the ones Corsair or Fractal Design make would help, along with some fans from Noctua.

I already figured that out.  They are binned better by intel.  That is, the selection process selects better components for the server chips.

The e3-1231 v3 im using right now is impressive for a $250 quad core.  In many cases it holds its own against top-line i7's.  I noticed that memory bandwidth in sandra measured 29mbs on my part, compared to about 21mb on my older i7-3770 (which is by no means a 'slow' or obsolete chip) and 25mbs max on an i7-4790K.

xeons also have dmi on chi (direct memory interface) which haswell i7's don't have.  THe smaller instruction set makes for faster computing.  The larger extended instructions on the i7-haswells are basically multimedia extensions for gaming.

I'm probably going to go with the 8-core xeon E5-2630 v3. For audio, more cores wins over speed since most DAW programs (I use cubase pro-8) will, for each track, where possible, assign a single core for that track to use.  What this results in is lower latency, though a quad core is usually sufficient.  In my case, playing electronic drums, I usually have 4~8 tracks going simultaneously when I play, at present my buffer is set for 6ms latency and I don't hear any pops or crackles (with the e3-1231 v3) 

By the way im sold on noctuna fans and heat sinks.

They are great fans.. if you can get past the hideous color scheme, or don't care.

Lol, I'm on a crappy Toshiba laptop :V

Well... not *that* crappy; I melted the camera and most of the keyboard with NP solvents and it still works great!

I have linux on it, too so the fucker flies (kali linux).

my mistake about my memory bandwidth measured 29GB/s on the e3-1231.

Benchmarks are overrated.  The real test is real-world performance.  I notice things like how 'snappy' or responsive a processor is, but most imortantly for audio, how much latency (i.e. what audio buffer size) I can use when playing an electroni drumkit live.  So far I am at 6ms, but im going to see if that can be lower with this processor--i think it can.

If latency isn't low enough, one can hear a lag between the time they play a note and when they hear it.
