6:45p	Qualcomm Refreshes Snapdragon 7c Chip for PCs and Chromebooks In late 2019, Qualcomm announced the Snapdragon 8c and 7c, a pair of affordable chips for always-on Windows 10 PCs and Chromebooks. Today, the company is updating the latter of those two SoCs to improve performance. Engadget: The Snapdragon 7c Gen 2 features a Kyro CPU that can achieve clock speeds of up to 2.55GHz. The company claims it delivers 10 percent faster performance than "most competing platforms." Qualcomm likely has processors from Intel's Gemini Lake family in mind here. The company also claims the 7c Gen 2 can deliver up to two times the battery life of its competitors. Outside of the faster CPU, the 7c Gen 2 is more or less the same chip Qualcomm announced in 2019. It features an Adreno 618 GPU and Snapdragon X15 LTE modem. The latter allows the 7c Gen 2 to hit theoretical download speeds of 800 Mbps. As with its predecessor, the chip is designed for education and price-conscious customers. According to Qualcomm, we can expect the first Snapdragon 7c Gen 2 laptops to arrive this summer, with the first models coming from Lenovo. Read more of this story at Slashdot. (Comment on this)
10:40p	Apple's Moves Point To a Future With No Bootable Backups, Says Developer The ability to boot from an external drive on an Apple Silicon Mac may not be an option for much longer, with the creation and use of the drives apparently being phased out by Apple, according to developers of backup tools. Apple Insider reports: Mike Bombich, the founder of Bombich Software behind Carbon Copy Cloner, wrote in a May 19 blog post that the company will continue to make bootable backups for both Intel and Apple Silicon Macs, and will "continue to support that functionality as long as macOS supports it." However, with changes in the way a Mac functions with the introduction of Apple Silicon, the ability to use external booting could be limited, in part due to Apple's design decisions. The first problem is with macOS Big Sur, as Apple made it so macOS resides on a "cryptographically sealed Signed System Volume," which could only be copied by Apple Software Restore. While CCC has experience with ASR, the tool was deemed to be imperfect, with it failing "with no explanation" and operating in a "very one-dimensional" way. The second snag was Apple Fabric, a storage system that uses per-file encryption keys. However, ASR didn't work for months until the release of macOS 11.3 restored it, but even then kernel panics ensued when cloning back to the original internal storage. In December, Bombich spoke to Apple about ASR's reliability and was informed that Apple was working to resolve the problem. During the call, Apple's engineers also said that copying macOS system files was "not something that would be supportable in the future." "Many of us in the Mac community could see that this was the direction Apple was moving, and now we finally have confirmation," writes Bombich. "Especially since the introduction of APFS, Apple has been moving towards a lockdown of macOS system files, sacrificing some convenience for increased security." [...] While CCC won't drop the ability to copy the System folder, the tool is "going to continue to offer it with a best effort' approach." Meanwhile, for non-bootable data restoration, CCC's backups do still work with the macOS Migration Assistant, available when booting up a new Mac for the first time.

11:20p	AMD Eyes Major Socket Change An anonymous reader quotes a report from PC Gamer: According to a tweet from Executable Fix, a well-known leaker, AMD will finally move away from PGA to LGA with the shift to AM5, the new socket set to replace AM4. They say the new socket design will be LGA-1718 -- the number representing the number of pins required for the package. They also note that a coming generation of AMD chip will support DDR5 and PCIe 4.0 with a 600-series chipset. When we talk about PGA, we're most often discussing processors with pins sticking out the underside of a chip that slot into a motherboard with a compatible socket. An LGA design will instead see a flat array of connection points on the processor, which will align with pins within the motherboard's socket. Either way you look at it, you're getting some very bendable, if not breakable, pins. But in my opinion it's much easier to bend those pins on the CPU. While a shift to LGA may seem somewhat trivial, the change will mark a major shakeup in AMD's desktop lineup. Read more of this story at Slashdot. (Comment on this)
