Here is the problem, I see numerous threads about haswell, and inputs on threads for people to wait, but what is that all about? 1) CPU 1.1) performance is going to be around 5-25% improved from the current ivy bridge line up. 1.2) There are some newer instructions for the cpu, those things make your cpu process your tasks faster 2) GPU 2.1) The gpu is going to be divided in several models: 4200 for ULV (read macbook air), 4600, 5100 and 5200, the last one is by logic the most powerful one, because it comes with more units that process the images and comes with embedded ram (its like the ram that comes in the gpu from the 15) 2.2) The expected performance from the 5200 is good, around the same improvement from the HD 3000 to the HD 4000, which was 50%, although there are people that think it will be lower than that, and I think it will be around the 640m that can be found in numerous notebooks 3) Battery life 4.1) New sleep state introduced, basically what this means is that your pc tries to make things as fast as possible and go to sleep, so it can save battery, but there are times when even when its "asleep" is too low, but in run mode its too fast 4.2) Aside that we expect some improvements regarding power consumption that are done with each new cpu that is released. And from the new chipsets 5) What Haswell isnt 5.1) Holy Grail 5.2) Flying Dutchman 5.3) Great boost in performance if you got ivy 6) Expectations 6.1) There are some expectations regarding the new mac line up, like: 6.1.1) MBP are going to die (I do believe that) 6.1.2) RMBP is going for some redesign (I do believe that) 6.1.2) Quads in the rmbp 13 (I want to believe that) 6.1.3) Different Sizes from what is currently offered, like 14'' or 17'' (I dont believe that) 6.1.4) RAM will be replaceable (unicorns do exist and fly, pegasus with horns) 6.1.5) Larger amount of RAM (I dont think it will happen on haswell, maybe broadwell since it introduces DDR4) 6.1.6) Dedicated gpu on the rmbp 13 (not only Im a talking fish, but I have a PHD in applied avionics for cows from the university Uranus) If you can wait, wait. if you need, buy it - its that simple.
