In version 3.0 there are additional features that include estimation of power on multi-socket systems as well as externally callable APIs to extract power information within sections of code.

The motivation for the tool was to assist end-users, ISV’s, OEM’s, developers, and others interested in a more precise estimation of power from a software level without any H/W instrumentation. Traditional methods to estimate power/energy usage of the processor has always been a cumbersome task that included special purpose tools or instrumentation on the platform along with third party equipment. With this release, it is providing the functionality to evaluate power information on various platforms including notebooks, desktops and servers.

It is supported on Windows* and Mac OS X* and includes an application, driver, and libraries to monitor and estimate real-time processor package power information in watts using the energy counters in the processor. Intel® Atom™ processors are not supported.

Silvermont's latencies for various x87 operations are often half of Saltwell's, with certain instructions outputting more than twice as often.Įven with these improvements, Atom will never be a heavy-lifting core, but it should handle a great deal of legacy code more gracefully than it currently does.Intel Power Gadget for Mac is a software-based power usage monitoring tool enabled for Intel® Core™ processors (from 2nd Generation up to 7th Generation Intel® Core™ processors). The improvements are substantial and non-trivial. We can't give you an exact breakdown of how Silvermont improves on this situation yet, but we've seen that data. This gives a throughput of only one instruction every two clock cycles, while a similar code using XMM registers would have a maximum throughput of two instructions per clock cycle.While latencies and throughput varied depending on the type of operation, Atom's x87 latencies and instruction throughputs were disappointing. Whenever there are two consecutive x87 instructions, the two instructions fail to pair and instead cause an extra delay of one clock cycle. CPU analyst Agner Fog describes the problem as follows: x87 FPU code running on Atom was pretty slow, partly by design, and partly thanks to a CPU bug that inserted a cycle of latency in between any two consecutive x87 operations. Many of the most significant changes to Atom's core for Silvermont are focused on how the chip handles floating-point code. Intel isn't using Hyper-Threading this time around, opting instead to go for a straight 1:1 relationship between threads and core count. The L2 cache has expanded and is now shared between cores. Shipping by end of year to meet Q1 2014 launches.Įxecution units have been redesigned for more efficient, lower-latency operation. First quad-core Atom, targeting holidays, 2013. Rangely - For comms, infrastructure products.Follow-up to Centerton, will debut later this year. Avoton - Low power SoC, aimed at servers.AMD's Brazos outperformed it decisively in 2011 and with Kabini (second-gen Brazos) and the Cortex-A15 both coming to market, Intel has finally given Atom the re-architecting it deserved. As someone who spent several weeks with an Intel-powered Gingerbread phone, I can honestly say that yes, you can put an Intel smartphone in your pocket, it works just fine, and battery life is decent.īut there's no hiding the fact that Atom is getting long in the tooth. On the one hand, this has paid off tremendously. Dual-core variants appeared on the desktop in fairly short order, and clock speed nudges have only bumped performance slightly higher. I was thinner, and had more hair.įor the past five years - and it'll have been nearly six years by the time these new Atom CPUs come to market - Intel has focused on improving power consumption, improving power consumption, and improving power consumption.

Nokia and RIM were major powerhouses in the cell phone industry and Windows Mobile's market share was still north of 35%. In smartphones, the Cortex-A8 - the first modern smartphone processor and the chip at the heart of Apple's iPhone 3GS - hadn't shipped yet. The Phenom II "Shanghai" refresh was still nine months away, Hector Ruiz was still CEO of AMD.

In the desktop world, we were talking about Windows Vista, Core 2 Duo, and AMD's original Phenom. And for more than half a decade, Intel has kept that same design. It drew on Intel's expertise in other areas and shared some design elements with the original Pentium, but Atom was its own unique design.

When it was initially announced, the 45nm, in-order core, based on the Bonnell microarchitecture, was a new product from the ground up. It's been six years since Intel first began talking about Atom.
