![]() ![]() Intel Intel Thread Director: how it all fits together “We exceed Skylake Core performance by consuming less power in a smaller footprint,” he added. If you put four E-Cores against a dual-Skylake system using four threads, you’d still get 80 percent more performance with less power, Robinson said. The new E-Core also delivers 40 percent more performance than Skylake. Four of the E-Cores (also manufactured in Intel’s Intel 7 process) take up the die space of a single Skylake core. ![]() That architecture was the sixth-generation Intel “Skylake” chip, and Intel’s efficiency core apparently supersedes it in every way. “The result is higher average frequency for any given application,” he said.Īn overview of Intel’s efficiency core within its Alder Lake chip. The performance core also integrates a new microcontroller that can examine the needs of applications in a microsecond, even faster than a millisecond. The chip’s caches have been improved to better accommodate data misses. While Goaz delved deep into the intricacies of the design, there are a few broad takeways: the P-Core is essentially wider and deeper than before, with the ability to perform better branch prediction for applications with a lot of code. IntelĪn overview of Intel’s performance core within Alder Lake. It has a new smart power management controller, too. Intel solved the latter problem with a new AI matrix engine coprocessor. But, according to Intel’s Koduri, this is the core that’s designed for pure speed.Īccording to Yadi Goaz, the director of the Intel Core CPU architecture, the performance core was designed to step up in general single-threaded CPU performance, but also anticipate the needs of AI and other functions in laptops, desktops, and servers. Officially, this is “Golden Cove,” but you’ll see it referred to merely as just a performance core. We often refer to Intel’s microprocessors by their code names-Skylake, Rocket Lake-but Intel has its own internal code names for just its CPU cores, too: the little-used “Sunny Cove” codename, for example. Intel’s “performance core” or “P-Core” is essentially the legacy of its Core chips, carried forward into Alder Lake. ![]() We do have the first inkling of how Intel’s performance core will perform, however. Remember that Intel’s first attempt at a hybrid processor architecture, Lakefield, came and went with reports of poor performance. An early snapshot of the Alder Lake chipset shows it offering x16 PCIe Gen 5 for graphics cards and a x4 connection to PCIe Gen 4, for SSDs.Īlder Lake’s overall performance remains somewhat of an open question. That, of course, will be likely gobbled up by both graphics cards and SSDs. PCIe Gen 5 supports up to twice the bandwidth of PCIe 4, or 64GBps across 16 lanes. Note that Alder Lake supports up to four Thunderbolt 4 ports as well as Wi-Fi6e.įinally, Intel’s Alder Lake will include Intel’s first support for PCI Express 5, announced in 2019. ![]() IntelĪccording to Daniel Rogers, the product manager for Alder Lake, the presence of fewer Xe EUs (32, as opposed to 96) on the desktop processor assumes the presence of discrete graphics. In the diagram below, for example, you can see that the desktop Alder Lake chip lacks Thunderbolt capabilities and has a smaller number of integrated graphics cores than the mobile Alder Lake chips do. Gihon referred to them as “building blocks,” and showed off some of the unexpected differences between the desktop and the mobile chips. Just as your car’s engine is really a collection of individual parts, so are Intel’s “chips” becoming a collection of individual logic blocks packaged together in various ways. Intel’s Alder Lake will offer you the option of buying new, hotter, more expensive DDR5 memory, but you should also have the option of reusing your older PC memory. (DDR5, a new memory technology developed in 2017, has been in the works for years, though it’s arrived a bit later than expected.) Arik Gihon, the chief architect of Alder Lake, told attendees that Alder Lake will be able to clock the memory speed up or down, saving power, in response to real-time heuristic analysis of the work being performed. The larger LGA1700 socket replaces the standard LGA775 socket used for well over a decade in the PC space, which means you’ll need to buy a new motherboard and cooler if you’re building an Alder Lake PC.Īlder Lake also uses a hybrid physical memory interface that supports four different memory types: DDR4-3200, LPDDR4x-4266, and also the brand-new DDR5 technology and its DDR5-4800 and LPDDR5x modules. For one, Alder Lake’s desktop processor will use an LGA1700 socket, an open secret that has surfaced as board makers and chip cooler makers design around the new chip. We already know of major changes affecting how Alder Lake PCs will be built, especially by DIY PC builders. ![]()
