Late Friday afternoon, I acquired an thrilling SMS notification—my assessment pattern of the brand new Raspberry Pi 400 had arrived. I realized of the brand new Pi mannequin final week whereas interviewing Raspberry Pi founder Eben Upton and Canonical desktop engineering director Martin Wimpress about Ubuntu 20.10’s newly improved desktop assist for the Pi {hardware} household.

Briefly, the Pi 400 is a barely sooner model of the 4GiB Pi Four which ships preassembled in a small, wedge-shaped chassis with built-in keyboard. The brand new mannequin instantly targets desktop alternative use and may be bought solo for $70 or as a full package (as seen above) for $100.

The brand new kind issue—which has apparently been within the works ever because the introduction of the official Raspberry Pi keyboard—addresses and enthusiastically helps the Pi 4’s rising use case as a alternative or different for the normal desktop PC. Upton advised Ars that the Pi 400 is about 20 % sooner than the Pi 4; it has largely the identical elements below the hood however on a in a different way laid-out board, and its BCM2711 CPU is clocked a contact greater than the BCM2711 within the Pi 4.

The most recent replace to Dell’s XPS 13 product line might be obtainable starting Wednesday, September 30, and can characteristic 11th-generation Intel CPUs, aka Tiger Lake. We all know quite a lot of AMD followers are going to be disillusioned at no Crew Crimson choice—actually, we’re a bit disillusioned, too; we have been extraordinarily impressed with this 12 months’s AMD Renoir laptop computer CPUs.

Nonetheless disillusioned AMD followers is perhaps, Tiger Lake represents a reasonably huge improve from final 12 months’s Ice Lake and Comet Lake lineup, as we noticed immediately once we had the possibility to check a prototype Tiger Lake laptop computer earlier this month. The 4 core/eight thread i7-1185G7 we anticipate within the highest-end XPS 13 fashions may not be a match for an eight core/sixteen thread Ryzen 7 4800U—however it hangs fairly even with an eight core/eight thread Ryzen 7 4700U, even on massively multithreaded workloads.

In the meantime, not each workload is massively multi-threaded—and the Tiger Lake i7 we examined demonstrated extraordinarily quick single-threaded efficiency. Extra importantly, its Xe built-in graphics had been far and away the very best performing iGPU we have ever seen—they don’t seem to be able to take the place of a gamer’s Nvidia RTX collection discrete GPU, however we suspect they sounded a loss of life knell for Nvidia’s cheaper MX collection of discrete laptop computer GPUs.
