This is half of what the M1 Macs should theoretically provide.

He also ensured that all the external SSDs were Thunderbolt 4 compliant.Īfter a lot of thorough testing, Oakley concluded that "no Thunderbolt port in any M1 model appears to fully support 10 Gb/s SuperSpeed+ in USB 3.1 Gen 2." The Intel iMac Pro provided read and write speeds in the range of 470-480Mb/s whereas Mac with M1 chipsets could only provide throughput of 406 Mb/s. The app he used to test the speed of USB-C ports transferred 160 files ranging in size from 2 MB to 2 GB. He conducted the experiment with three Mac models: one MacBook Pro with an M1 Pro chip, one Mac Studio with an M1 Max chip, and an Intel iMac Pro to compare the results. Oakley carried out various tests to determine that M1 Macs actually don't fully support Thunderbolt 4. Orignal NameĮven though these standards claim to deliver speeds in Gpbs, practically this isn't possible "because of encoding and other overheads." Oakley says that USB standard claiming "5 Gb/s should yield around 500 MB/s, 10 Gb/s gives around 1200 MB/s, and 20 Gb/s about 2400 MB/s." The problem with M1 Macs Source: Pocketnow This will also help you understand why some M1 Mac users are complaining that their device isn't offering the speed that Apple claims. Let's take a look at the table of various USB-C standards and learn more about the max speed they offer. However, due to its naming scheme and terminology, many users don't actually know the data transfer speeds their USB-C port can offer. With the latest USB-C 3.1 Gen2x2, you can even get up to 20Gbps data transfer speeds - something that was unimaginable a few years ago. In addition to offering a symmetrical design, USB-C also offers better transfer speeds than any other USB standard that has been created yet. But, this isn't the only factor why USB-C is popular. One of the advantages of USB-C over the previous USB-A version, which made it popular, is that the USB-C ports feature a symmetrical design meaning the cables can be inserted in any orientation - up or down - thus eliminating frustrations of previous USB standards. Various USB-C versions and their max transfer speedsĪs we all know, USB-C is the new USB standard moving data and power to and from a wide variety of computing devices. But, before we get into how Oakley reached the conclusion that M1 Macs don't truly support Thunderbolt 4, let's take a look at various USB-C generations and the difference in transfer speeds that they offer. A new report from Howard Oakley from Eclectic Light claims that even though Apple says that the new Macs support Thunderbolt 4, they don't truly support USB 3.1 Gen 2. However, it appears that the M1-based Macs fall short in one key area. Most of the new M1 Mac owners are left impressed by the performance and efficiency their Mac can offer. The Apple Silicon-based devices from the Cupertino giant offer a lot of improvement in comparison to the Intel-based Macs. and then we follow up with a recommendation which equates to "Let's please put these out of their misery.Apple M1 Macs have truly changed the game for laptops and desktops.

As noted above, check your computer's warranty status via Dell's web site. The Precision workstation model line, though, changes less frequently as of early 2012, for example, we still occasionally purchased new Precision T3500, T5500, and T7500 models. In May 2011, for example, when the OptiPlex 790 shipped, we stopped buying the OptiPlex 780.

Historically, Dell changed OptiPlex models every 12-18 months, and we switched to the latest models immediately. * These are the approximate years that the models shown first became available. Models below this line are not suitable for ECN support please contact us to discuss options.** Although ECN-supportable, will the models above meet your needs? See "How often should my computer be replaced" in our PC desktop recommendations page. Some computers might require memory upgrades. When repurposing existing computers, ECN recommends only the use of models from 2015 or newer.
