How neuromorphic ‘brain chips’ will begin the next era in computing

How neuromorphic ‘brain chips’ will begin the next era in computing Part of the reason a digital computer is more efficient than a human being is its transistors can fire with incredible speed — but so can our neurons.Similarly, we will eventually look back at the attempt to do learning operations with digital chips, including GPUs, as inherently unwise or even silly.

Specialized processors might reignite performance scaling, but they’ll also change the nature of computing forever

Specialized processors might reignite performance scaling, but they’ll also change the nature of computing forever Modern CPU scaling has largely flatlined, thanks to a combination of scaling challenges, intrinsic limits to silicon performance, and a general shift in the market towards lower power devices.To demonstrate, here’s a graph of Apple iPhone single-core CPU performance in Geekbench 2 and Geekbench 3.

Using hardware queues to break the multi-core CPU bottleneck

Using hardware queues to break the multi-core CPU bottleneck Each CPU will have its own L2 cache, where data related to the problem is stored.In a coherent cache, CPU 0 completes part of its calculations, writes a new value to a block of memory, and then communicates that it has done so.

Intel rolls out the rest of the Kaby Lake CPU family

Intel rolls out the rest of the Kaby Lake CPU family The initial Kaby Lake mobile refresh was limited to a handful of SKUs; with this launch Intel is bringing out a larger number of cores intended for every price point.The slideshow below steps through each of Intel’s SKUs in some detail, but we’ll give you the 10,000-foot overview.

The Mac's user share just fell to a five-year low

The Mac's user share just fell to a five-year low In the years after it converted to x86 and launched the first Core 2 Duo Macs and Mac Pros, Apple enjoyed increased market share and better Mac business performance.Even after the iPhone and iPad had dwarfed Macintosh sales, it remained a potent additional income stream and Mac market share grew throughout the Great Recession and the decline of the PC market.

With Kaby Lake, Intel finally brings Hyper-Threading to its Pentium-branded processors

With Kaby Lake, Intel finally brings Hyper-Threading to its Pentium-branded processors Last week, we reviewed Intel’s Core i7-7700K and discussed the details on the Kaby Lake refresh cycle, including Intel’s new Core i3, i5, and i7 processors.The CPU giant announced multiple new Pentium-class CPUs based on Kaby Lake, including the first Pentium SKUs to feature Hyper-Threading since Intel retired the Pentium 4.

AMD's Ryzen CPU sort of gets a release date

AMD's Ryzen CPU sort of gets a release date While AMD has edited their invitation to remove all reference to Ryzen, eagle-eyed folks managed to screencap the information first.Hat tip to Overclockers3D, who noticed the invitation and screencapped the Ryzen invitation.

AMD posts strong Q4 2016 results, confirms Ryzen, Vega launch dates

AMD posts strong Q4 2016 results, confirms Ryzen, Vega launch dates Currently, most of AMD’s revenue is driven by console sales, and Microsoft and Sony order the most hardware in Q3 as they ramp up to meet holiday demand.The company has more cash on-hand, and while it’s carrying a higher inventory load, that’s likely related to the upcoming Ryzen launch.

The Pentium G4560 with Hyper-Threading is a potent budget processor

The Pentium G4560 with Hyper-Threading is a potent budget processor Last month, Intel launched its 7th generation refresh of the Core processor family, codenamed Kaby Lake.The Pentium G4560 is in the middle of this new family of Pentiums — its clock speed of 3.

Intel responds to AMD’s Ryzen onslaught with some Core i7 and i5 updates

Intel responds to AMD’s Ryzen onslaught with some Core i7 and i5 updates However, Intel isn’t standing still in the face of Ryzen’s impending release, Hexus reports.More: Leaked roadmap shows AMD may release three classes of Ryzen desktop processors According to Canard PC, a French publication, Intel is planning to both adjust Kaby Lake pricing and push out some new versions directly in response to Ryzen.

Intel will finally finish Fab 42 in Arizona, bring new 7nm capacity online

Intel will finally finish Fab 42 in Arizona, bring new 7nm capacity online Several years ago, Intel announced that it wouldn’t finish its 14nm manufacturing plant, Fab 42.Now, Intel has announced that it will be bringing Fab 42 online, but not as a 14nm facility.

AMD Ryzen CPUs are readily available, but Ryzen motherboards? Not so much

AMD Ryzen CPUs are readily available, but Ryzen motherboards? Not so much As LegitReviews notes (and ExtremeTech confirmed), there aren’t a whole lot of motherboards currently in stock for the platform.There’s currently a bit of a gap between how AMD has described the desire for its platforms (strong demand!

AMD rumored to be working on a 16-core, 32-thread Ryzen CPU due later this year

AMD rumored to be working on a 16-core, 32-thread Ryzen CPU due later this year Their release is said to be several months away, so it may not be long before AMD reveals a 16-core, 32-thread Ryzen CPU with support for quad-channel DDR4 memory.Although AMD’s Ryzen CPUs have received some criticism for their single-core performance and gaming ability, they have excelled in applications and settings where the full power of their many cores and threads can be utilized.
