Intel 7th Gen Core Series Kaby Lake WaferIntel is readying a new family of processors based on its next-gen Kaby Lake microarchitecture. We’ve heard quite a bit about Kaby Lake over the last few months, and were even able to show you it in action last week while covering IDF, but today we’ve got many more details to share on the microarchitecture that will be foundation of Intel’s upcoming 7th Generation Core processors.If you’re unfamiliar with Kaby Lake, it is the follow-up product to last year’s Skylake. Kaby Lake borrows heavily from Skylake; its CPU cores, cache structure, and graphics engine... Read more...
Researchers at Princeton University recently showed off a 25-core processor they designed specifically for data centers. It's called "Piton," named after the metal spikes rock climbers hammer into cracks or seams of mountainsides to anchor their position, and it's built after a scalable architecture that could boost processing speed while cutting back energy use. Piton represents several years of research and development by David Wentzlaff, a Princeton assistant professor of electrical engineering and associated faculty in the Department of Computer Science, and his students. It's also a rare thing—Wentzlaff... Read more...
We're getting so close to AMD's release of Zen that it almost feels like you can reach out and grab it, though obviously that's not the case, at least not yet. During a recent earnings call with investors, AMD boss Dr. Lisa Su stated that Zen would trickle out by the end of the year before shipping in any kind of real volume in the first quarter of 2017. "We have been very focused on the [Zen] server launch for first half of 2017. Desktop should launch before that," Dr. Su stated. "I believe it will be in the first quarter of 2017. We may ship some limited volume towards the end of the fourth quarter,... Read more...
Intel shook things up when it announced that Kaby Lake would sit in between Skylake and Cannonlake, thus disrupting its tick-tock release cadence with a third generation processor family based on a 14nm manufacturing process. Now it appears that a fourth generation family of 14nm CPUs is on the roadmap, that being Coffee Lake, which will be behind Intel's first six-core processor for mainstream users. If you want to own a six-core CPU from Intel right now, your best bet is to save up your funds and build a system around Broadwell-E or Haswell-E, both of which are aimed at enthusiasts. Intel hasn't... Read more...
There is one constant in the world of supercomputers: no one is going to be 'fastest' for long. In fact, some supercomputers can seem downright slow after only a couple of years, as hardware continues to become faster and more dense. Take for example Oak Ridge's TITAN supercomputer. Launched in 2013, this supercomputer managed to push about 20 petaFLOPs of throughput (17.59 pFLOPs LINPACK; 27 pFLOPs theoretical). At the time, that was downright mind-blowing. But consider TaihuLight, China's latest supercomputer, coming in at 93 petaFLOPs. For those who don't want to grab a calculator or exercise... Read more...
A bunch of researchers at the Department of Electrical and Computer Engineering at the University of California, Davis (UC Davis) have built a "many-core" processor unlike any other. Aptly named KiloCore, the new CPU contains a staggering 1,000 independent programmable processors, which is presumably the first of its kind."To the best of our knowledge, it is the world's first 1,000-processor chip and it is the highest clock-rate processor ever designed in a university," said Bevan Baas, professor of electrical and computer engineering.Baas led the team that designed the chip architecture. While... Read more...
Back in March, Intel launched its Xeon Processor E5 v4 family of products, based on the Broadwell-EP core. We had the chance to evaluate a dual Xeon E5-2697 v4-based system with a total of 36 cores (72 Threads) and detailed some of the changes and new features in Broadwell-EP. As powerful as that 36-core system was, the E5 v4 family is not Intel’s top-end server offering. That designation belongs to the Xeon E7 v4 product family being announced today, which typically features more cores, more cache, and support for additional sockets.Xeon E7 v4 Processor, Top And BottomThough they are a different...

AMD just released some details regarding its upcoming seventh generation of A-Series and FX APUs, formerly codenamed Bristol Ridge. Bristol Ridge is essentially a refresh of the previous generation Carrizo design and uses the same 28nm process. In lieu of a die shrink, however, AMD has made improvements to the manufacturing process, tweaked the transistor mix, and enabled new features that were previously dormant in Carrizo, and the end result is higher frequencies at a given power level, in addition to some IPC (instructions per clock) improvements. The newly activated features... Read more...
It's a good thing Intel waited until the weekend to let slip a mention of its forthcoming Core i7-6950X Extreme Edition processor on its website, because had the Santa Clara chip maker jumped the gun, everyone might assume it was an April Fool's Day prank. That's not the case for what we surmise is a mighty 10-core CPU (more on that in a moment).To be clear, Intel hasn't launched the Core i7-6950X, not yet anyway. But what the company did do is update its support website for its latest Management Engine software, listing the much anticipated Broadwell-E part as a compatible chip. So in that way,...

Intel is officially launching a brand new series of Xeon processors today, the Xeon Processor E5 v4. Unlike mainstream desktop products, which feature Intel’s latest core technologies like the Skylake-based Core i7-6700K, mission-critical, big-iron parts like the Xeon E5 v4 series are more complex and go through much more qualification, and as such tend to leverage core technologies that have long been proven in the consumer space. The the Xeon Processor E5 v4 family, for example, is based on Broadwell, or more specifically Broadwell-EP. We’ve already got a plethora of Broadwell coverage up here... Read more...
For nearly a decade, Intel has followed a "tick-tock" release strategy for its processors. However, as Intel attempts to transition its manufacturing process from 14 nanometers to 10 nanometers, it's running into challenges that has the Santa Clara chip maker seemingly thinking about abandoning its tick-tock model.Before we go any further, let's talk about the tick-tock model for a moment. Starting in 2007, Intel followed a cadence that consisted of transitioning existing architectures to a new process node (tick) followed by releasing a new architecture on that same node (tock). For example, Broadwell... Read more...
It's 2016, and it feels like we've been waiting forever for AMD to launch a strong attack against Intel with a fresh group of desktop processors that compete in the high-end. With Intel dominating the CPU scene for so long, three user groups have emerged: those who still buy AMD chips because the value proposition is still quite good, those who want to buy AMD to support the company but can't resist the allure of higher-performing competitive CPUs, and those who are completely indifferent to a brand and just buy whatever suits them. With Zen, AMD is hoping that the latter two groups will... Read more...
We've said it before and we'll say it again, it's ridiculously difficult to keep a secret in the Internet era. That applies to companies both small and big—even Intel isn't immune from this. Case in point, you're not supposed to know this yet, but Intel is preparing to launch a new flagship Xeon D processor.It's the Xeon D-1571 based on Intel's 14nm Broadwell architecture. Intel hasn't announced the CPU yet, but for a short while, it appeared on an updated CPU price list. Intel yanked the price list offline and replaced it with an old one, but not before the folks at CPU World could screenshot... Read more...
Toward the beginning of the year, it was revealed that Microsoft was going to "unlock" the seventh core on the Xbox One's processor, enabling developers to eke just a bit more performance out of the console and offer more flexibility at resource utilization. It appears that Microsoft's move would inevitably be followed by Sony, as reports are now coming in that this will be made available on the PlayStation 4 as well. This subtle change was highlighted in the latest changelog for the FMOD sound engine. Labeled as a "LowLevel API" update, it reads, "PS4 - Added FMOD_THREAD_CORE6 to allow access... Read more...
