Then 1) Apple is run by a bunch of idiots for waiting on chips than don't exist rather than building computers around the chips that do. Like everybody else. And 2) it is just hilarious that some people seem to think Apple is right for selling 3 year old tech as if it were new while waiting for these chips to show up.
There are plenty of appropriate CPUs and GPUs. Apple just needs to have the courage to keep up with modern times and choose modern chips.
Because the 15" MBP is just so much more capable than the MSI-GS62 right? Same form factor yet the MSI has an i7 quad core skylake, a gtx 970, a 4k screen, and multiple industry standard drive bays. The updated version with Kaby and the GTX 1070 should be hitting the street before the MBP refresh. And unlike Apple, there are some fantastic deals on the MSI machines right now because they're almost a year out of date. And if you don't mind going a bit thicker than the MBP, MSI has some amazingly powerful machines. If you prefer thinner, Razer makes some amazing MBA killers.
Interesting! The MSI machines do indeed look quite capable, but as has been noted, the Skylake CPUs they use (i7-6700HQ) don't have the IrisPro graphics - but if you have the gtx970, it's arguable that you don't need it.
Apple certainly could have used Broadwell parts on the MBP 15 if they wanted. I imagine they simply considered the cost of upgrading the CPU (which must have some re-design and re-tooling cost) and their market for this machine, and simply decided it wasn't worth it for them. Same story for the Mac Mini and Mac Pro - just not enough market share to really affect profits if a few people are offput buying them due to the older CPUs. In the case of the Mac Pro, I expect they analysed the median professional user replacement cycle and thought that most people use these machines for about 5 years (no idea, but it sounds reasonable), and so their upgrade cycle will align to this. As a new buyer though, you generally don't want hardware more than a year old, so they do lose out on this market. I saw a guy in an Apple store buying a Mac Pro a couple of weeks ago and thought - "don't do it!" - but maybe he needed it and just couldn't wait for the rumors to resolve into reality.
