Small 200MHz speed bump, 16GB RAM standard on all Retina MacBook Pro 15” and a small $100.00 price cut on the 15-inch 2.5GHz high-end model.
Obviously this update is a mid cycle update, until Intel releases the mobile versions of i5 and i7 Broadwell processors, now pushed back to 2015.
I’ve read some negative comments about this update coming from some people who obviously think that a better specced Mac would improve their empty lives. For the record, most complaints were about the discrete graphics card that the Retina MacBook Pro 15” uses. It’s a NVIDIA GeForce GT 750M.
Some users called for an upgrade to the GTX 850M. It is my understanding that the NVIDIA GTX 850M requires a redesign of the motherboard. It is unlikely that any vendor would put any resources on redesigning a motherboard at half cycle. We’ll get new discrete graphics cards but when Apple releases the new Retina MacBook Pro with Broadwell chips. And that depends largely on Intel.
