Ever since Intel and Micron announced in 2015, the world has been waiting for the companies to use it to build memory sticks. 3D XPoint blends the properties of flash storage and DRAM memory. Like flash, it's persistent, retaining its value even when systems are powered down, and it's dense, with about 10 times the density of DRAM. Like DRAM, it supports low latency random access. Intel also claimed that its write endurance is substantially better than that of flash. This combination of features created the prospect of memory sticks that look like DIMMs and appear to the system as if they're DDR4 RAM but with much greater capacities and with persistence: data written to 'RAM' is retained permanently.
Intel Optane is a new storage technology that can be used as either a super-fast SSD or additional system RAM! Learn all about it right here. Squarespace link: Visit. Intel Optane Memory Module 16 GB PCIe M.2 80mm MEMPEK1W016GAXT (Certified Refurbished) $25.99 (11) Works and looks like new and backed by a.
Memory with these properties is exciting for a wide range of applications—for example, databases that no longer need to concern themselves with flushing data back to disk—and might one day provoke significant changes in the way operating systems and software are designed. But while persistent memory was perhaps the most interesting application of 3D XPoint, the first products to hit the market were simply storage drives using 'Optane' as their branding.
There was a and some consumer-oriented designed to be paired with a spinning disk to produce a high-speed hybrid. While 3D XPoint did offer some benefits over flash SSDs—in particular, the latency of the drives is significantly lower than that of comparable flash units, and the I/O performance is sustained even under heavy mixed read/write workloads—this wasn't quite the revolution that we were hoping for.
Today, Intel announced Intel Optane DC Persistent Memory. This is a series of DDR4 memory sticks (with capacities of 128GB, 256GB, and 512GB) that use 3D XPoint instead of traditional DRAM cells. The latency is a bit worse than real DDR 4, but the sticks are persistent.
Although they use the standard DDR4 form factor, they'll only be supported on Intel's next-generation Xeon platform. Intel is pitching the new memory as a way to greatly increase the amount of memory available to processors and eliminate the latency that normally occurs when moving data from memory to persistent storage. This is valuable to a range of database-like and caching workloads. The persistence means that freshly booted servers no longer need to load terabytes of data into memory—the data is, in effect, already there. Because persistent memory has such big implications for software developers, Intel will also have a scheme that gives developers (under NDA) remote access to machines using Optane Persistent Memory so that they can develop and test software that takes advantage of its persistent capabilities. Beyond this basic information, there's still a lot we don't know about Optane DC Persistent Memory: performance, endurance, power consumption, system/processor compatibility—all remain unknown at this point.
Intel is also vague on the product's availability: wide availability is going to happen some time in 2019, but selected customers will be able to get their hands on it this year.
Update, July 24: Apple has confirmed the widespread on its 2018 MacBook Pro models, which have emerged since the laptops were released earlier this month. CPU clock speeds were slowed down as internal temperature spiked during high-load computing sessions. The company says the issue was, and that it has issued a patch in the form of the MacOS High Sierra 10.13.6 Supplemental Update that should address it. Check out our forthcoming review to see test results before and after the patch is applied. The article originally published July 12 follows.

The is getting a midsummer update - but it's a specs-focused, under-the-hood component refresh that leaves the unchanged. The 13-inch and 15-inch MacBook Pro models with secondary display are getting updated CPUs, new and storage options, a new T2 subprocessor for security and encryption and hands-free. The controversial butterfly keyboard, meanwhile, is getting tweaked a bit - but it won't be completely overhauled. The entry-level 13-inch MacBook Pro model without the TouchBar is unchanged for now, as is the rest of the Mac lineup, including the 12-inch, and desktop Macs. The 2017 MacBook Pro models, which look identical to the new 2018 models. Sarah Tew/CNET The two updated MacBook Pros keep the current starting prices of $1,799 (13-inch) and $2,399 (15-inch).
And Apple is offering two new accessories: A third-party external GPU option, and new laptop sleeve cases. 2:49 New eighth-gen Intel processors The 15-inch Pro moves from older quad-core processors to current-gen, six-core Core i7 and Core i9 parts.
The 13-inch Pro moves from dual-core CPUs to eighth-gen, quad-core i5 and i7 models. RAM, storage and battery upgrades For the 15-inch MacBook Pro, people who work with lots of large files will be pleased to hear that the max RAM has been doubled, from 16GB to 32GB. The RAM itself moves from older DDR3 memory to newer DDR4. You can find, but the upshot is that DDR4 is faster and allows for higher capacities, but can also use more power, potentially lowering battery life.
To make up for this, the new MacBook Pros have a larger battery, crammed into the same chassis. Apple says the combination of faster RAM and a larger battery should be a wash, with no change to real-world battery life. Storage capacities have been doubled as well, from 2TB to 4TB in the 15-inch and from 1TB to 2TB in the 13-inch. From ZDNet. True Tone jumps in from iOS True Tone, a feature found on recent and, uses light sensors to automatically adjust the color temperature of the display to best match your viewing environment. It can make the color range warmer or colder on the fly.
For example, the screen will display colors in a way that better matches what that color would look on a real-world wall or object in your current lighting conditions. If you need to be more precise about color while editing photos, illustrations or video, you can turn off True Tone in the settings menu. T2: Smudgement Day No, it's not a killing machine from the future made of liquid metal, it's the second generation of fingerprint-reading system-on-chip (SoC) processors for controlling certain security features.
In the previous MacBook Pro, the T1 handled fingerprint sensing for TouchID, data encryption and more. The fingerprint reader on an older (but identical-looking) MacBook Pro. Sarah Tew/CNET The T2 version, already available in the, adds a few extras, like a secure boot path to make sure no tricky malware sneaks into your bootup process. But for those of us hoping for, the wait continues. Siri, do you hear me?
The Siri smart assistant has been available on Macs since 2016, but you couldn't wake her up simply by saying, 'Hey Siri,' without going through a. Now, she'll hear you, just like on your iPhone. A quiet (keyboard) place Loud, clacky typing (the kind produced by Apple's current super-flat keyboards) threatening to? The new MacBook Pro models have a tweaked third-generation version of that keyboard that purports to be quieter. Giving it a quick typing test, it wasn't whisper-quiet, but it did lack the sharp click of the previous design. But if you were waiting for a keyboard fix to tackle the issue some users have of dust or debris causing keys to stick, you're out of luck. Apple says this keyboard update has no new engineering or tweaks to address that issue, currently the subject of both and a.
Leather laptop sleeves It's important to remember that all the changes and updates listed here apply to the TouchBar versions of the 13-inch and 15-inch MacBook Pro. They don't apply to the 13-inch Pro without the TouchBar, the, the or any other Mac hardware. But, if you do spring for one these systems, you may want to keep it covered up in one of Apple's new MacBook Pro leather sleeves. Apple already makes these for the 12-inch MacBook, and the new 13- and 15-inch versions will come in brown, blue and black.
They'll be $179 for the 13-inch and $199 for the 15-inch. Blackmagic eGPU boxes for Mac Also new is a third-party eGPU (external graphics processing unit) from a company called Blackmagic.
Unlike most eGPU boxes, like the, this one has a vertical design and built-in AMD Radeon Pro 580 graphics hardware, rather than simply a slot for inserting your own off-the-shelf graphics card. It'll be $699 and can output directly to Thunderbolt displays and feed 85W of power back to your MacBook. What about the rest of the Mac line? These updates are all about the 13-inch and 15-inch MacBook Pro. What about the rest of the Apple lineup? Apple analyst Ming-Chi Kuo just published a research note with, which pretty much anticipates a refresh of nearly everything else the company produces that hasn't yet been updated this year. It includes:.
5.8-inch and 6.5-inch iPhones with OLED screens, plus a 6.1-inch LCD iPhone. New iPad Pro models (11-inch and 12.9-inch) with FaceID and no Home button. A new generation of with advanced heart-rate detection. Updates to the 12-inch MacBook and, as well as a new Mac Mini and a replacement for the long-serving MacBook Air In other words: If you've got your eye on any Apple computer besides the MacBook Pro with TouchBar, it's back to the waiting game. The annual iPhone launch in early September is the next obvious choice on the calendar. But that's just a guess - nothing is locked in. We'll be testing and reviewing the updated MacBook Pro just as soon as we can get one.
