Hi all,

I’m looking to purchase a 15-inch MBP and am a little confused by the 2 options Apple is currently offering (not looking at the old model).

As far as I can tell by looking at the base configurations, the only difference is the 2.8 vs 2.9 GHz, as the 2.8 GHz version can be upgraded to 512GB storage with Radeon Pro 560 to match the 2.9 GHz specs. Both models have Kaby Lake.

Am I missing something? Were these released separately?

Thanks!

The 2.9 and 3.1 processors have 8MB L3 cache vs 6MB for the 2.8. Not sure how big of a deal it is but thought I would chime in.

No you have pretty much got the gist. you can upgrade the base model and have the 512gb and pro 560 for 100 dollars less than the higher tier offering. The only time its worth going for the more expensive one is if you want to upgrade storage and processor to 1tb or more and the 3.1ghz.

This is what I was going to point out. Seems to be the big improvement between the base chip and the upgraded ones.

Unless your workflow involves high CPU usage for sustained periods of time (e.g. number crunching stuff), it's unlikely you will ever notice differences due to a higher cache hit rate. I'd personally recommend CPU upgrades only if execution time is an important factor, otherwise the money is usually better spent elsewhere.
