I hate to tell you, but checking e-mail and browsing, are what "most people" do with their computers, maybe with some youtube videos and netflix on top of that. Very few, relative to the total number of users, play demanding games or encode video. I would argue just the opposite, that for the vast majority of users, a haswell dual core pentium or i3 is more than adequate.
Holy hell .Seems this was not the case and he just impulse buys whatever seems best, without regarding his own light casual workload thats more suited to a dualcore.
Apple just updated its series with Broadwell. Includign Core M for the air. So much for the ARM rumours.
So the both updated MBAs and 13in rMBPs have Broadwell... but the only latter has a battery life boost: a measly 1hr jump to 10hr.
It seems like the 11in MBA version, with a large ratio of CPU consumption to everything else, should at least have a good bump in specced battery numbers from 14nm alone. I'm hoping that Apple downplayed the numbers to make the new retina 12in Macbook (which I've no interest in) seem better in comparison, but this is so disappointing.
Believe me there is not a large ratio of CPU consumption to everything else.
The largest consumer of power is the screen, especially on ultrabooks.
I have to say, the Xeon D looks like the future of the Xeon lineup to me, the product poised to ship in the largest numbers overall once the market comes to understand it. Big cores like Broadwell are usually most power-efficient when operating at the lower end of their possible voltage and frequency ranges, and Intel's latest process tech innovations have offered their biggest benefits at lower voltages. Dual-socket servers can run higher clock speeds, but those speeds come at less efficient operating points. 2P systems also tend to burn lots of power on their socket-to-socket interconnects.
The Xeon D should be excellent for providers of cloud and web services. I'd expect firms like Google and Facebook to snatch them up quickly. Intel also points to applications like web caching, storage, and networking as key for this product. The chipmaker expects the big data, HPC, and enterprise markets to stick with the Xeon EP. I suppose that makes sense, but I expect the Xeon D to be powerfully appealing in any case where a single application doesn't require more memory or compute power than a Xeon D can supply in a single node. That kind of makes 2P the new 4P, if you follow my meaning.
We don't yet have full pricing and specs on the various Xeon D models Intel will offer. We do know that the Xeon D-1450 will have eight cores with a base clock of 2.0GHz, an all-core Turbo peak of 2.5GHz, and a single-core Turbo peak of 2.6GHz. Meanwhile, the Xeon D-1520 will feature four cores with a 2.2GHz base frequency, 2.5GHz all-core Turbo, and a 2.6GHz single-core peak. Both chips should be available this month.
Intel has provided us with a few preliminary benchmark results for the Xeon D compared to Avoton. They show the Xeon D to be as much as 3.4x faster with up to 1.7x higher performance per watt. However, those numbers are based on pre-production hardware and look kind of shaky. I suspect we'll see better numbers published in the coming weeks.
Not that simple.
Ever since 4th Gen Core(Haswell) Intel focused on platform improvements. They do *more* than the CPU improvements. Lot of cases though, process tech changes are translated solely into better performance rather than lower power.
If screen was the vast majority of power use, then in light workloads, Core and Atom chips should have similar battery life. That's not the case. Atoms still have nearly 2x the battery life of Core devices per WHr.

Not exactly something you slap together over night.
Pretty typical power numbers. [...]
It is very rare for Intel to come out and announce a new integrated platform. Today this comes in the form of Xeon D, best described as the meeting in the middle between Xeon E3 and Atom SoCs, taking the best bits of both and fitting into the market for the low-end server market prioritizing efficiency and networking. Xeon D, also known as Broadwell-DE, combines up to eight high performance Broadwell desktop cores and the PCH onto a single die, reduces both down to 14 nm for power consumption/die area and offers an array of server features normally found with the Xeon/Avoton line. This is being labeled as the first proper Intel Xeon SoC platform.
Adding in the Ethernet onto the SoC is rather interesting because the SoC is rated at a 45W TDP. Normally a server chipset is rated for around 13W, with 10G Ethernet at 7-13W. Thus even the additions of storage and networking can come to 20W, leaving 25W for the cores themselves. As a result, the cores are clocked at 2.0 GHz base for the 8-core D-1540, and 2.2 GHz for the 4-core D-1520. Both SKUs will turbo up to 2.5 GHz when needed.
Intel is placing some interesting claims on performance, specifically 3.4x better performance of the high end SKU compared to the Atom C2750 (eight core Silvermont) and 1.7x better performance per watt. Breaking down these comparisons, we have Silvermont against Broadwell which has a significant difference in architecture, and then an eight-core/eight-thread C2750 against the eight-core/sixteen-thread D-1540, which should improve the performance when software can take advantage of the threading. The performance per watt should have been expected moving from 22nm Silvermont to 14nm Broadwell. Bundle these in together, and the 3.4x / 1.7x numbers seem a reasonable comparison. The more poignant number perhaps is the 5.5% IPC increase over Haswell due to microarchitecture improvements:
This is you implying the part in question is not a "K" CPU:
It appears that the unlocking of the multiplier is a very small bone being thrown to the enthusiast, other than that it would appear to be a low TDP chip for BRIX and NUC etc.
Apple just updated its series with Broadwell. Includign Core M for the air. So much for the ARM rumours.
Yes, it looks like they only changed the CPU, keeping the TDP at 15W (so they are not passively cooled).Core-M is only for the new "Macbook". Air is broadwell i5/i7 apparently.
“Two or three years ago Intel was ahead [in process technology] and foundries were striving to catch up, [but now]…perhaps some of that gap is closing,” said Saleem Haider, a senior marketing director at Synopsys. “For FinFET processes, we are very much in the phase where customers are calling on us for support with production designs,” he said.
Most of the issues around the need for double-patterning lithography got worked out in the 20nm nodes with chip designs that started as early as 2005, said White. At the 10nm node, foundries are starting to choose diverging paths with some adopting self-aligned double patterning and others moving to triple patterning, she said.
Here comes your daily those of FinFET FUD :

Well, I guess it doesn't matter. The foundry camp can brag that they're in phones ahead of Intel with 14nm, but Intel can start the timer when it moves to post-silicon next year . [spoiler alert: suddenly, then, the gap will grow from "closing" to 4 or so years.]
The news was released the same day archrival Cadence Design Systems announced Innovus, its next-generation physical design tool which claims significant speed ups in FinFET and planar processes.
and enter the senior marketing director:...said Mary Ann White, director of product marketing for Synopsys’ Galaxy Design Platform
and finally the "article" ends with what is essentially a PR dueling match:...said Saleem Haider, a senior marketing director at Synopsys
This kind of marketing PR BS is not worth the time spent reading it. Best just to move on.“We partnered closely with Cadence to use the Innovus Implementation System during the development of our ARM Cortex-A72 processor,” said Noel Hurley, general manager of ARM’s CPU group, speaking in a Cadence press release.
I first read that as "Macbook Air i5/i7 doesn't have a fan, and has the same design as Macbook Core M" but am not sure if I'm reading your post correctly. :hmm:Yes, it looks like they only changed the CPU, keeping the TDP at 15W (so they are not passively cooled).
