Haswell rMBP w/ Traktor
Haswell rMBP w/ Traktor Posted on: 26.10.2013 by Forrest Weeks Now that we have the new Haswell powered rMBPs, do anyone have any idea/info about how they fair w/ traktor?I'm curious cause Haswell is all about efficiency and saving power, one of the ways they achieved this is by switching b/w power states. Now anyone trying to reduce audio dropouts and glitches would know that switching b/w power states/frequency can actually cause a DPC spike. Also the fact that this cpu has the Iris pro gpu inside it, I'm kinda worried before I put my money on this new machine. | |

Can you confirm if the problem exists even if you turn off your discrete graphics via that third party? I really hope NI comes out with a fix. |

Since discrete graphics normally create problems like overheating I was intending to get one without it (like the 2011 MBPs faced severe overheating issues).
The link you provided is from a Windows user too so it doesn't exactly apply. "Latency spikes" have never really been an issue for Macs.

Dannie Dimora 08.12.2013 | I just ordered a fully specced (2.6/16/1tb/gt750m) model.. I hope it doesn't give any such problems.. |

Rosenda Gossage 06.12.2013 | I bought 15" rMBP (the model with the discrete graphics card). I get crackles from my Audio 8 (using the 2.6.0 driver, TSP 2.6.5, and Mavericks). This occurs whether I'm using scratch control or CDDA through the card. NI support has suggested things I've already tried (different USB cable, different USB port, turning all the energy saving stuff off). There's a thread on the NI community s - so I'm not the only person having this issue. One guy has drawn a parallel with the issues when rMBP's first came, and has contacted the guy who came up with a workaround then (involved changing a kext on the MBP so that it was using the old 2.0 USB drivers) to see if he can sort something similar this time while we wait for NI to sort their driver out. If I get a job in the meantime, I'm seriously considering switching to Serato. Note that there's no way in Mavericks to force the discrete GPU without a third party program: gfxCardStatus |

Chuck Peretto 07.11.2013 | I am need of a new Macbook myself ( my old one is about 7 years old). I am interested in one of these Haswell rMBP but have a few concerns and questions for you, the DJTT community. Maybe not a big difference in either choice, but 8 GB or 16 GB regarding RAM, and 2 or 2.3 ghz when it comes to the CPU? I feel 8 would be enough, but am a bit concerned about future proofing and what RAM apps may require in the future (4-5 years out). I'd like to hold onto my next laptop for at least another 5 years. As far as cpu is related, I'm believeing 2.0 i7 quad core would be enough, but wasn't certain. Would I get a lower latency setting from a bit bigger processor or more RAM? Has anyone picked up a new rMBP yet that could tell me if they are having good results without a dGPU? I wouldn't mind having the 750m one in mine, but wasn't looking to spend quite that much just to get one. I'm not a big gamer, nor do I work with 3D imaging. I do want to keep running Traktor 2.6 and beyond though. And finally, good results with Mavericks OS so far (except for some external controller compatibility, and the power key that can put the computer to sleep when you didn't mean to)? I read about those on the Mavericks thread. Thanks for your help. Feel free to share your cpu and RAM configurations if you are currently using Mavericks and Traktor with no problems. |
Alphonso Deitchman 04.11.2013 | Yes, that's to be expected since they carry large numbers of the stock models. |
Forrest Weeks 04.11.2013 | If you customize the base 15" rMBP to match the CPU, RAM and SSD of the higher end one, the price difference becomes $0, but with no dGPU. http://store.apple.com/us/buy-mac/ma.../A&step=config, it is the same 2599 bucks as the 15 rMBP (2.3/512/16) w/ the discrete graphics. Also 1 of my friends bought it from apple store in Denver and he confirmed that price for both are the same. |
Alphonso Deitchman 04.11.2013 | Where are you seeing ones with and without discrete graphics at the same price? I don't see any in the online store. Edit: figured it out. If you choose all the upgrade options to match, the prices match too since BTO costs more than stock configs. |

Alphonso Deitchman 27.10.2013 | The 15" model without discrete graphics is much cheaper. If you push your latency lower than your system can handle you'll get glitches and crackles on a Mac too. But random spikes don't tend to happen and there's no extensive system optimisation necessary beyond the obvious things like WiFi/Bluetooth and hard drive sleep. The main issue that could still occur is problematic drivers for new hardware configurations, and it can sometimes take a while for stable drivers to be released. |

Alphonso Deitchman 27.10.2013 | Almost all of the new Macbooks have no discrete graphics, so turning internal graphics off just isn't an option. The link you provided is from a Windows user too so it doesn't exactly apply. "Latency spikes" have never really been an issue for Macs. |

Delena Katherman 26.10.2013 | Curious about this as well. |
