2.5 quad-core i7 vs 2.6 quad-core i7 processor

I'm looking to buy a new MacBook Pro and I've narrowed it down to two options:

The newest 15'" MBP model (released yesterday):
2.6 quad-core i7
512 GB SSD
16GB 1600MHz memory
Cost: $2,599

Refurbished 15" MBP May 2015 model:
2.5 quad-core i7
512 GB SSD
16GB 2133MHz memory
Cost: $2,199

There's large savings with the refurbished computer, and as far as I can tell the only difference is the processor and the newer/older models and features.

Is the newest model still worth the investment if it's only 2.6 when the older model is 2.5? Also, I'll have to buy USB adapters and an SD adaptor for the newer model if I get it, which is even more money. However, if I want this laptop to last at least 5 years for my video editing career, then maybe it's worth the extra $400 + adaptors?

 

@belladeshotel Mac? 5 years of serious work? You must be joking! On more serious note, newer model seems much more interesting choice to me, especially in the long run - but you should definitely review your expectations.

 

Newer MBP has little more battery life thanks to skylake and radeon pro. The newer ones comes only with usb type c connectors while killing off more common ports like SD card, USB2/3 ports etc. If you need latest and greatest PC with a low profile form factor which is actually easier to carry then Newer MBP must be your choice. If you're choice is to plug it AC every time, then older mbp with eGPU solutions utilising TB2 is more affordable and probably would give you more performance per $.
Its better to hear some more inputs from experienced users.

 

16GB RAM and 512GB (effectively 319GB after OP'ing from an actual/nominal 476GB available) SSD on a thermally limited system?

Why?

How long do you want your career to last for? (A few weeks)?

Find a mobile computer which gives you 32GB RAM now (with 64GB RAM possible) on the fastest and latest platform you can afford and at least dual drive bays which you should setup as a 1TB or larger SSD (main drive) and the biggest data drive (still would recommend an SSD though) you can fit into the second drive bay. SATA3 still preferred over M.2 drives for sustained, heavy duty use.

Powered by Windows 10 x64 Pro.

For the same money or less than what you're considering now. Even if it was more $$$ (for dual 1TB or larger SSD's, 64GB DDR4 RAM, etc.), you will be much further ahead than buying either of those options today.

Are you editing youtube clips (minutes long)? Or film length clips? VGA resolution or 4K?

16GB RAM and a half a TB SSD doesn't cut it for video editing 5 years ago. Let alone today.

Or, buy the fruity computers if you just want to look like a video editing pro.

Good luck. (Especially if you drink the koolaid).

 

Unless OP use Final Cut Pro or other Mac SW for content creation and manipulation, consider looking into other powerful PC/lappies that come with better thermals and upgradeability. Clevo, MSI, Asus, Dell or Lenovo are good.
If you need a workstation consider buying a mobile workstation from Lenovo or Dell which has workstation gfx to do your editing work. Even Windows PCs come with TB ports so don't worry about compatibility between your friend's mac and yours. Look for system specs recommended by @tilleroftheearth .
