It all boils down to 'more of the same, but slightly better'

While Intel is having another crack at Skylake, its competition is trying to innovate, not only by trying new designs that may or may not work, but they are already showcasing the next generation several months in advance with both process node and microarchitectural changes. As much as Intel prides itself on its technological prowess, and has done well this decade, there’s something stuck in the pipe. At a time when Intel needs evolution, it is stuck doing refresh iterations.

One of the recent topics permeating through the custom PC space recently has been about power draw. Intel's latest eight-core processors are still rated at a TDP of 95W, and yet users are seeing power consumption north of 150-180W, which doesn't make much sense. In this guide, we want to give you a proper understanding why this is the case, and why it gives us reviewers such a headache.

VT-x is name of CPU virtualisation technology by Intel. KVM is component of Linux kernel which makes use of VT-x. And QEMU is a user-space application which allows users to create virtual machines. QEMU makes use of KVM to achieve efficient virtualisation. In this article we will talk about how these three technologies work together. Don't expect an in-depth exposition about all aspects here, although in future, I might follow this up with more focused posts about some specific parts.

Among many of Intel's announcements today, a key one for a lot of users will be the launch of Intel's 9th Generation Core desktop processors, offering up to 8-cores on Intel's mainstream consumer platform. These processors are drop-in compatible with current Coffee Lake and Z370 platforms, but are accompanied by a new Z390 chipset and associated motherboards as well. The highlights from this launch is the 8-core Core i9 parts, which include a 5.0 GHz turbo Core i9-9900K, rated at a 95W TDP.

Looking inside the Intel 8087, an early floating point chip, I noticed an interesting feature on the die: the substrate bias generation circuit. In this articleI explain how this circuit is implemented, using analog and digital circuitry to create a negative voltage.

Intel introduced the 8087 chip in 1980 to improve floating-point performance on 8086/8088 computers such as the original IBM PC. Since early microprocessors were designed to operate on integers, arithmetic on floating point numbers was slow, and transcendental operations such as trig or logarithms were even worse. But the 8087 co-processor greatly improved floating point speed, up to 100 times faster. The 8087's architecture became part of later Intel processors, and the 8087's instructions are still a part of today's x86 desktop computers.

Intel has set a concrete deadline for when it'll finally have processors built on a 10nm process in the mainstream market: holiday season 2019.

While the company's 14nm manufacturing process is working well, with multiple revisions to improve performance or reduce power consumption, Intel has struggled to develop an effective 10nm process. Originally mass production was planned for as far back as 2015. In April, the company revised that to some time in 2019. The latest announcement is the most specific yet: PC systems with 10nm processors will be in the holiday season, with Xeon parts for servers following soon after. This puts mainstream, mass production still a year away.

Intel's recent demonstration of a 28-core processor running at 5GHz has certainly stirred the pot here at Computex, particularly because the presentation appeared to imply this would be a shipping chip with a 5.0GHz stock speed. Unfortunately, it turns out that Intel overclocked the 28-core processor to such an extreme that it required a one-horsepower industrial water chiller. That means it took an incredibly expensive (not to mention extreme) setup to pull off the demo. You definitely won't find this type of setup on a normal desktop PC.

We met with the company last night, and while Intel didn't provide many details, a company representative explained to us that "in the excitement of the moment," the company merely "forgot" to tell the crowd that it had overclocked the system. Intel also said it isn't targeting the gaming crowd with the new chip.

Alongside the launch of Intel's first 5 GHz processor, the 6-core Core i7-8086K, Intel today also showcased a 28-core single socket machine also running at 5 GHz. The system on display scored 7334 in Cinebench R15, and Gregory Bryant (SVP and GM of Intel Client Computing Group) explicitly stated that it would be coming in Q4 this year.

No other details were provided, however for it to exist in a current platform, this new processor would likely be in LGA2066 (X299) or LGA3647 (the server socket). Intel technically already makes 28-core monolithic designs in the Intel Xeon Scalable Platform with the Xeon Platinum 8180, which is a $10k processor, which runs a lot slower than 5.0 GHz.

Intel has announced that, once again, mass production of its 10-nanometer "Cannon Lake" chips will be delayed. The company is already shipping the chips in low volumes (though no one knows to whom at this point), but said it "now expects 10-nanometer volume production to shift to 2019 ." It announced the move in its first quarter earnings report, which saw it collect a record $16.1 billion in revenue and $4.5 billion in profit, a 50 percent jump over last year.

The company is announcing two specific TDT features. The first is "Advanced Memory Scanning." In an effort to evade file-based anti-virus software, certain kinds of malware refrain from writing anything to disk. This can have downsides for the malware - it can't persistently infect a machine and, instead, has to reinfect the machine each time it is rebooted - but makes it harder to spot and analyze. To counter this, anti-malware software can scan system memory to look for anything untoward. This, however, comes at a performance cost, with Intel claiming it can cause processor loads of as much as 20 percent.

This is where Advanced Memory Scanning comes into effect: instead of using the CPU to scan through memory for any telltale malware signatures, the task is offloaded to the integrated GPU. In typical desktop applications, the GPU sits there only lightly loaded, with abundant unused processing capacity. Intel says that moving the memory scanning to the GPU cuts the processor load to about two percent.

XScale is a microarchitecture for central processing units initially designed by Intel implementing the ARM architecture (version 5) instruction set. XScale comprises several distinct families: IXP, IXC, IOP, PXA and CE (see more below), with some later models designed as SoCs. Intel sold the PXA family to Marvell Technology Group in June 2006. Marvell then extended the brand to include processors with other microarchitectures, like ARM's Cortex.

The most important parts of Intel’s new Vaunt smart glasses are the pieces that were left out.

There is no camera to creep people out, no button to push, no gesture area to swipe, no glowing LCD screen, no weird arm floating in front of the lens, no speaker, and no microphone (for now).

From the outside, the Vaunt glasses look just like eyeglasses. When you’re wearing them, you see a stream of information on what looks like a screen - but it’s actually being projected onto your retina.
