http://ark.intel.com/compare/91166,91164,91167 Am I understanding correctly these are the processor options for the new 13" Touchbar MBP? If yes, what's the point of the i7? Why is it even called an i7? I thought the difference was the i7s had hyperthreading, but these i5s do, too.

Looking at refurb 2015 MBP 13" -- For anything less demanding than video editing, is there a meaningful difference between the i5 and i7, assuming identical options (SSD, 16 GB RAM)?

It's all out the window other than "i7 faster than i5 at given wattage".

I'm looking to build a (Windows) computer with an LG Ultrafine 4k: I'm looking at that display too, since I'm intrigued by the P3/size combo. It's not available for another month and a half though, so I'd wait for reviews to come out, because I'm not sure if regular DisplayPort 1.2 will be able to drive the displays with an adapter.

EDIT: A lot of companies call it "flash storage" when it's part of the mainboard. "SSDs" commonly refers to a packaged drive that is separate from the mainboard whether it plugs in via SATA or M.2 or whatever, but the underlying tech is the same.

Well flash storage also refers to CF cards and SD cards and various non-volatile memory of the past that can be flashed, like your BIOS chip, and those are all nowhere near as fast as the SSDs used for general purpose computing storage. I forget why they call it 'flash' but yeah basically all solid-state non-volatile storage is called 'flash memory' or 'flash storage' and could even accurately be called 'SSD' but that's usually used for the fast ones you use to run your computer. edit: On Wiki and various sites it says it's called 'flash' because it could be 'erased in a flash', but I'm pretty sure I recall reading that the first re-writable 'ROM' (oxymoron I know) could be erased with a literal flash of UV light. Either way, these days it just means 'solid-state non-volatile storage' . Pivo fucked around with this message at 05:37 on Nov 3, 2016 |

Hey, sorry if this has been asked here before, but I've got a maybe/kinda/possibly deal that I have to close now or not. Been having trouble trying to figure out how to get results through google without triggering a thousand false positives. I'm looking at buying a late-2015 iMac that has a 256 SSD (no fusion drive). Do non-fusion-drive iMacs still have the SATA connection/HDD area accessible and usable? In other words, can I buy this rig, throw a 1TB SSD into the HDD area, and be good to go? Will the iMac just recognize that the SATA connection is being used and act as if it is a fusion setup?Or is this prevented with solder/software? juststraightbangin fucked around with this message at 04:34 on Nov 3, 2016 |

I don't know about the usability of the SATA slot with the iMac model you are buying, it might just not be on the board, but I dunno (though I know they're a bitch and a half to get into anyway, check iFixIt) but I do know that a Fusion drive does not just happen by accident. If you want to create a Fusion drive from your SSD+HDD, there's a process involved. If the slot's there and you plug in an HDD, it'll be JBOD. Hope someone else has more insight.

Am I going insane or does the MacOS retina scaling use improper gamma correction? I looked at a gamma chart using a program that let me set my laptop to 2560x1600 (left), and then again using the normal 1280x800 2x scaling (right). When the display is forced to work without scaling the gamma looks spot on, but with scaling on it's all hosed up. And yes the webpage is at 100% scaling so the browser isn't introducing any scaling errors.  This can't be right, can it? Am I missing something?

Apple apparently didn't manage to work around the (known and documented) USB 3 <-> 802.11 2.4 Ghz interference issues in the new MBP.  Plugging some USB 3.0 devices completely kills WiFi according to this video. https://www.youtube.com/watch?v=NYVjIjBMx6o Granted it is likely the fault of a badly shielded device/cable but the old MBP and a Dell works fine under the same circumstances. I read that the new MBPs use a special coating on the speakers as the antenna instead of regular antennas in the screen like the old devices, which could explain this behaviour. Or perhaps he's just holding it wrong. edit: here's a Intel whitepaper from 2012 on this topic. http://www.intel.com/content/dam/www/public/us/en/documents/white-papers/usb3-frequency-interference-paper.pdf Apple is going to get slaughtered in the media if this turns out to be a real world issue, particularly because the device depends more on these ports than any other machine. Of course they'll say 2.4 Ghz is outdated technology and everybody ought to use 5 Ghz networks. eames fucked around with this message at 10:37 on Nov 3, 2016 |

I cannot watch more than a few seconds of the asshat techbro in this video without wanting to put a spike through my eyes. I will lay good odds it's a poorly shielded device (or perhaps techbro hosed up RFI shielding on the Mac/another device while tearing it apart? IDK, because I didn't find where in the video he tested wifi, because I like not committing self harm). USB3 uses a 5GHz physical layer, which is a great frequency for interfering with 802.11 2.4, and often the resulting RFI issues are straight up voodoo (working fine on other machines doesn't mean much).

When shopping used/refurb MBPs on Amazon, is there a reliable way to tell the release date for each computer? Some of the listings include a serial number, so I can then look it up myself, but most don't, and pretty much zero of them say, "mid-2015" or whatever. They just list the specs. I imagine a "2.5 GHz i5" (for example) spans several years of production, yes?

Biodome posted:This will probably blow over by this time next week after it's discovered this isn't a real thing, actually. Actually I'm inclined to believe that it is a quite real thing. I noticed vastly diminished transfer rates over WiFi (10 Megabyte/s versus 70 Megabyte/s on 801.11ac) on my then new 2013 rMBP. It took me a long time to isolate the bottleneck to the interference from my USB 3.0 SSD. When I swapped the SSD into to a Buffalo enclosure and connected it TB2 the problem went away. This is reproducible and anyone who thinks it "isn't a real thing" is invited to read the white-paper linked above. Whatever, the vast majority of the people who buy these new Pro machines will never attach peripherals, so they won't notice.
