Processor

How much of a difference will an I7 or Xeon processor make over an I5.

That can be a loaded question, but in terms of benchmark values, this is a good site to see benchmarks versus CPU cost. Bear in mind that as a sysem, the CPU is only one part of the greater whole.

ASUS ROG Maximus X Hero (Wi-Fi AC), i7-8700k, 16GB RAM, GTX-1070Ti, Win 10 Pro, Saffire PRO 24 DSP, A-300 PRO, plus numerous gadgets and gizmos that make or manipulate sound in some way.

i7 has more threads (physical and virtual cpu) so effectively can do more multitasking. Xeon is a workstation CPU and can run in parallel with another using SMP (Symmetric Multiprocessing) which requires dedicated RAM per processor. So won't provide you with a great benefit probably unless you are going to be working lots of number-crunching and server applications. IMHO
 
In DAW terms that could be a sequencer with lots of hardware and external input. Hope that summarises it.

There are many quad core i5s and also dual core i7s so as mettelus pointed out, it can be a loaded question. Generally speaking more cores (even virtual ones) are better for DAWs.

For DAW purposes, a Xeon CPU brings *zero* benefit.
In fact, if the clock-rate is significantly lower, you'll take a significant performance hit.
Don't want to sacrifice significant clock-speed for more cores.
In a perfect scenario, high clock-speed *and* more CPU cores.

I think the only exception to that rule is that there are more multiple CPU mobo's for Xeon and Xeons with more cores than the 6 maximum in the i-series, correct?

Re: Processor 2017/08/01 22:42:38 (permalink)
The only disadvantage I can see is 32 PCI lanes. So if you use a dedicated GPU that leaves 16 split between the rest of the devices. However with x4 and x8 being other bus options and providing no lanes get shared or disabled by use of another. It shouldn't be much a hinderance. They have massive memory support although perhaps the memory speed is an issue. So not for gamers however if it was more affordable and in the right scenario of these could make an excellent workstation. I mean 20 physical cores....geez you could run 300 plug-ins and Sonar will still be like a demanding girlfriend.
 
Having said that, an i7 or i9 if you money will stretch that far will be a better option in the long run.

Thanks everyone. I have a decent understanding of computers, but trying to decide on whether to go power laptop alone or decent laptop and desktop is driving me crazy along with trying to retrofit my Liquid Saffire 56 to a PC laptop. I just want to get back to making music. I can use all the technical help I can get.

Something to think about regarding the number of CPU cores and laptops/desktops.
 
In the desktop version, i5 and higher are usually quad-core, but in laptops, you could only end up with a dual core.  They do that for power saving and extended battery life, but at the potential expense of performance.
 
For instance I have an i5 laptop (non DAW), but it is only dual core with 1.7GHz turbo to 2.5Ghz.  It is slower than my i3 desktop (DAW), which is dual core and locked to 3.4 GHz.  Both have 4 threads due to hyperthreading.
 
So I would say at least an i5 quad-core in the 3-4 GHz range would be worth looking at. 
 
The clock speed is the bottom line as far as how fast a single thread can perform.  The more cores/threads you throw at it, the more work your CPU can do concurrently.  The i7 is ideal for a heavily loaded Sonar DAW due to the plugin load balancing with 4 cores/8 threads. 
 
But is up to the software developer to take advantage of multiple cores/threads.  A badly coded app that is single threaded can only run as fast as your max CPU clock speed.  The other cores will not help in that case.

DAW: CbB; Sonar Platinum, and others ...

The new i9 7900x is the best of all worlds (expect cost).  
10 cores at 4500MHz

The only disadvantage I can see is 32 PCI lanes. 


With socket 1151, the 7700k provides 40 PCIe lanes
With socket 2011-3, the 6850k (on up) provides 40 PCIe lanes.
With socket 2066, the 7900x is currently the only CPU that provides 44 PCIe lanes.
 
Lower end CPUs provide 28 PCIe lanes.
 
On a simple build, it's a moot point.
On a more complex build (multiple video cards or multiple PCIe x4 SSDs), it's pretty limiting.
 
At $600, it's disappointing that the new i7-7820x is limited to 28 PCIe lanes.
For the power-user who's not pushing the absolute limits, the 6850k (socket 2011-3) is still a great choice.

I was referring to the Xeon , however it did answer another question.

Quick note for the OP, Jim Roseberry (who has already chimed in on this thread) is an excellent source of info for computer builds. If you have specific options you are considering, Jim can pretty readily chime in with the pros/cons and suggestions for what your needs are. He also builds machines (see the link in his signature), so if you want to go that route, it is another option available through him - he builds computers with the main purpose of them being a DAW in mind.
 
That said, laptops will never reach the power/performance of a desktop for the same cost, but they can certainly meet your needs for both functions (seems that you want the portability of one even if you have a desktop). Can you expound on how you will generally be using the machines (DAW only, general use, etc. and in what type of environment/venue)?

Not at the same cost, obviously, but for a little extra you can get pretty serious performance with modern mainstream desktop processors (e.g. i7 7700K) and 64GB DDR3 RAM in a laptop case. It's become quite possible to use it as desktop replacement, unless your needs are in the top extremes.
