Thanks all for comments! Makes sense I'm more clear now.
The only thing that doesn't make sense is the pricing. Refurbished MBP 2015 directly from Apple UK is 1.6k (same time they sell it as brand new at 1.9k) with Hashwell inside so basically they telling ppl to purchase a 2k laptop which will not be able to do what the 1.2k 13'' potentially can do because of KABY and not the quad core, i7, etc.
How can they price 2015 MBP 15'' so much more than the normal 13'' kaby when the disclaimer of Apple clearly states 6th generation and above for high sierra etc. I don't know i find it oxymoron
Because display of 10-bit does not matter to most people. It does not matter at all to me in how I use my laptop. But when processing power the 8 thread of executions from the quad core high throughput CPU versus the 4 thread dual core low power CPU really does matter. It means the difference of tasks taking 5 or 15 minutes.
And if they would just put an Nvidia 1060 in the machine I could be done in under 1 minute.
