I am considering buying either 13 or 15 inch rMBP and with regard to the former something from Anandtech's review has caught my attention: "By far the biggest issue with buying the 13-inch MacBook Pro with Retina Display is that you know, in about a year, it'll be updated with even better hardware. It's very clear to me that the 13-inch rMBP was built with Haswell in mind. Without enough room for a discrete GPU, a CPU with significantly faster processor graphics (~2x in the case of Haswell) will open up the 13 to even more customers. Haswell should boast improvements in idle power, however since it's still built on Intel's 22nm process (like Ivy Bridge) it's not abundantly clear to me how active power will be impacted. Looking at the thermal data for the 13-inch rMBP alone leaves me comfortable saying there's some room to introduce more power hungry silicon without making the system unusable." 1) Considering his assumption that due to thermal data on current 13 inch power hungry silicon is likely to be introduced based on 22nm as in Ivy Bridge, does he mean that battery life will likely be shorter or we cannot know this now? 2) What is the likelihood that 13 inch rMBP will include quad-core Haswell processors? 3) Let's assume in the next-gen 13-inch rMBPs there will an option for dual-core Haswell and quad-core Ivy Bridge, is it possible to know which one would likely perform better if they have similar clock speeds? Thanks and merry X-mas to you all!
