Apple Doubles MacBook Pro R/W Performance 204

Lucas123 writes Benchmark tests performed on the 2015 MacBook Pro revealed it does have twice the read/write performance as the mid-2014 model. Tests performed with the Blackmagic benchmark tool revealed read/write speeds of more than 1,300MBps/1,400MBps, respectively. So what's changed? The new MacBook Pro does have a faster Intel dual-core i7 2.9GHz processor and 1866MHz LPDDR3) RAM, but the real performance gain is in the latest PCIe M.2 flash module. The 2014 model used a PCIe 2.0 x2 card and the 2015 model uses a PCIe 3.0 x4 (four I/O lanes) card. Twice the lanes, twice the speed. While Apple uses a proprietary flash card made by Samsung, Intel, Micron and SanDisk are all working on similar technology, so it's likely to soon wind up in high-end PCs.

    What a missed opportunity for a semicolon after "Samsung", and what a confusing sentence as a result.

  • So you can hook up to an external monitor OR charge your Iphone OR make a powerpoint presentation! In 2016, it will be even lighter when they reduce the number of letters in the alphabet for the keyboard.

      Dunno if you were joking or not, but in case you weren't, note that the MacBook Pro has (by my count) 8 ports. It's the new MacBook (not Pro) that has only the single USB-C port.

      Or they can just introduce a slipstream charger adapter so that you can plug the power cord and the monitor cord into the same thing, leave that on your desk, and only connect one cable when you get home. And once monitors start supporting USB-C natively, they'll just do the same.

      Just as with dropping PS/2, floppy drives, and optical drives, someone always has to go first.

      Keep in mind that the target audience for the Macbook is far less likely to use an external monitor, or even to plug it in at all during

    • But they said that after analysis of customer data, they've found most of users don't need all the letter in keyboard :P
  • Since when did we start calling SSDs Flash Modules or Flash cards? (The article uses both). Can I now call platter hard drives magnetic modules?

    • There's a bit of confusion, but essentially there is a big difference to flash memory that is presented as a replacement hard disk and talks over SATA, and a flash card that talks to the computer over PCIe through a motherboard PCIe slot.

      Essentially, PCIe is a darn sight faster than SATA, so when you hook up a flash drive to it, it goes at ludicrous speeds.

        I see you've been reading the press release.

        Do you believe ever piece of BS you read in PR? There's a buttload of crap where that one came from. It's the salesman's job to sell you fancy NEW MOAR BETTER CRAP, so I guess if it's working, he's gonna keep his job :D

          Not referring to the drive in the article, but if you think it's all marketing bull, measure it yourself. In NVMe's case, getting rid of the SATA and SAS translation layer has cut out over 60% of the CPU overhead, and cutting out the max 6Gbps or 12Gbps speed means the drives can go insanely fast. That's a lot of real change by using NVMe. Now, I am one of those marketing guys who work for one of these companies, but I can tell you it's not all BS.

      Since when did we start calling flash chips SSDs? I remember when SSDs were a bunch of RAM chips behind a disk target chipset, so you got a really small (but really honking fast!) disk for your database logs, mail queues, etc.

      • by MobyDisk ( 75490 )

        We started calling them SSDs when they presented themselves as hard drives. While these connect through the PCI bus, the BIOS sees them as hard drives.

    "Twice the lanes, twice the speed"...man someone doesnt understand the PCIe standard or how to do simple math. Its actually twice the lanes, FOUR* times the (theoretical) speed. 2x500MB/s vs 4x985MB/s * rounded up
    • by cdrudge ( 68377 )

      Isn't it kinda arguing semantics? Can't you argue that the speed has doubled (500 -> 985MB/s), as well as the number of lanes, but your bandwidth has quadrupled.

    The raw bandwidth available for transfers isn't doubled, it's quadrupled. PCIe 3.0 is twice as fast as PCIe 2.0, channel for channel, so the bandwidth would have doubled even if they had not added two more channels. They doubled it in two different ways at the same time.

    That said, the old flash was probably not being that badly constricted by the older standard, and the current generation is only capable of twice the throughput. However, adding even more bandwidth than that is a nice bit of future-proofing and quite welcome.

    • by fgouget ( 925644 )
      They say the SSD is PCIe 3.0 but is the slot it's plugged into PCIe 3.0 or still PCIe 2.0? Too little is known to be sure that this combination actually doubled the bandwidth per lane, though it's certainly plausible.

Let's organize this thing and take all the fun out of it.

Working...
