  • How much faster is a Gen 6 i7 compared to a Gen 2 i7?

Hi guys, I have been using my trusty Intel i7 2600 for about 6 years. It's a real steamroller with 24GB DDR3 RAM and I have made many many albums with it  - it it the core of my business and it pays my bills.
 
I had it in for a new power supply a few days ago and was surprised when the PC shop quoted me a lot less than I would have thought to do an i7 of the latest flavour with 16GB Corsair/Kingston DDR4 on the board.

It's seriously tempting from a fun point of view but my only justifiable reason to upgrade would be to save production time somewhere.
 
So, can anyone shed any light on what I could expect from an upgrade like that?
Bounce Time
Stability
Any other performance benefits?

Pretty sure you're going to need a new motherboard (which you would want, to take advantage of the new chipset)

This seems like an alright primer:

Thanks, I am aware of that. I was just wondering about the potential performance gain :O)

Assuming we are comparing an i7-2600 (no special code) to an i7-6700 (no special code), the 6700 is a little faster but not by any life changing amount:
http://www.cpu-world.com/Compare/426/Intel_Core_i7_i7-2600_vs_Intel_Core_i7_i7-6700.html
 
DDR4 RAM is likewise a little faster than DDR3 but also not by a life changing amount.  
 
Let's say you have a task that is pure CPU/memory processing that takes 10 minutes on your 2600.  On the 6700, it might take 7-8 minutes.  Probably not going to make a huge difference in your day to day life.  
 
Throw in the fact that you'd be losing 8 GB of RAM on this and I'd probably skip it.

If this is your only computer and if it were me I would look at a replacement. Not for the reason to gain performance,more to have a back up machine if your main business computer fails. Being 6 years old is starting to get to the place where bad things can happen. Of course bad things can happen anytime, but the potential is greater.
 
You would get a slightly faster computer as a side benefit. If your old computer is working ok, then performance isn't a good reason to upgrade.

FWIW, There would be lots of small benefits to having a current generation machine.  
The sum of which adds up to a significant upgrade... 
  • It will be able to run more DSP.  Not by a major factor but still beneficial
  • If you want to run Win10, it runs best with current generation hardware.
  • If you plan on running the latest software, it works best with current generation hardware.
  • Intel USB-3, USB-3.1, Thunderbolt-3, etc. (depending on the motherboard).
  • Faster Boot-up
  • More Intel SATA-III ports (depending on the motherboard).  This helps when running SSDs.

I always check the raw performance numbers of the CPUs. Here's a very good site:
https://www.cpubenchmark.net/high_end_cpus.html
Other relevant factors are sizes of caches, types of memory, speed of memory, etc. Newer chips are also much better at sleeping, turning on turbo, keeping the pipelines full etc.
 
I would not put any more money into a second generation i7, and instead go for a current 6th gen
 
EDIT: I meant to also say that the chipsets improved as well, so your SATA interface, USB 3 vs USB 2, makes it easy to move on.

Thanks guys, valuable input indeed. L
