Intel's high-end desktop (HEDT) processor line will reportedly be moving from Haswell-E to Broadwell-E soon, and with the move Intel will offer their highest consumer core count to date, according to a post at XFastest which WCCFtech reported on yesterday.

While it had been thought that Broadwell-E would feature the same core counts as Haswell-E (as seen on the leaked slide above), according to the report the upcoming flagship Core i7-6950X will be a massive 10 core, 20 thread part built using Intel's 14 nm process. Broadwell-E is expected to provide an upgrade to those running on Intel's current enthusiast X99 platform before Skylake-E arrives with an all-new chipset.
WCCFtech offered this chart in their report, outlining the differences between the HEDT generations (and providing a glimpse of the future Skylake-E variant):

It isn't all that surprising that one of Intel's LGA2011-v3 processors would arrive on desktops with 10 cores as these are closely related to the Xeon server processors, and Haswell based Xeon CPUs are already available with up to 18 cores, though priced far beyond what even the extreme builder would probably find reasonable (not to mention being far less suited to a desktop build based on motherboard compatibility). The projected $999 price tag for the Extreme Edition part with 10 cores would mark not only the first time an Intel desktop processor reached the core-count milestone, but it would also mark the lowest price to attain one of the company's 10-core parts to date (Xeon or otherwise).

A great way to shave money off of a minimalist system is to skip buying a GPU and using the one present on modern processors, as well as installing Linux instead of buying a Windows license. The problem with doing so is that playing demanding games is going to be beyond your computers ability, at least without turning off most of the features that make the game look good. To help you figure out what your machine would be capable of is this article from Phoronix. Their tests show that Windows 10 currently has a very large performance lead compared to the same hardware running on Ubuntu as the Windows OpenGL driver is superior to the open-source Linux driver. This may change sooner rather than later but you should be aware that for now you will not get the most out of your Skylakes GPU on Linux at this time.
"As it's been a while since my last Windows vs. Linux graphics comparison and haven't yet done such a comparison for Intel's latest-generation Skylake HD Graphics, the past few days I was running Windows 10 Pro x64 versus Ubuntu 15.10 graphics benchmarks with a Core i5 6600K sporting HD Graphics 530."

Coming just a day after Qualcomm officially launched their Snapdragon 820 SoC, Samsung is today unveiling their latest flagship mobile part, the Exynos 8 Octa 8890.
The Exynos 8 Octa 8890 is built on Samsung’s 14 nm FinFET process like the previous Exynos 7 Octa 7420, and again is based on the a big.LITTLE configuration; though the big processing cores are a custom design this time around. The Exynos 7420 was comprised of four ARM Cortex A57 cores and four small Cortex A53 cores, and while the small cores in the 8890 are again ARM Cortex A53, the big cores feature Samsung’s “first custom designed CPU based on 64-bit ARMv8 architecture”.
“With Samsung’s own SCI (Samsung Coherent Interconnect) technology, which provides cache-coherency between big and small cores, the Exynos 8 Octa fully utilizes benefits of big.LITTLE structure for efficient usage of the eight cores. Additionally, Exynos 8 Octa is built on highly praised 14nm FinFET process. These all efforts for Exynos 8 Octa provide 30% more superb performance and 10% more power efficiency.”
Another big advancement for the Exynos 8 Octa is the integrated modem, which provides Category 12/13 LTE with download speeds (with carrier aggregation) of up to 600 Mbps, and uploads up to 150 Mbps. This might sound familiar, as it mirrors the LTE Release 12 specs of the new modem in the Snapdragon 820.
Video processing is handled by the Mali-T880 GPU, moving up from the Mali-T760 found in the Exynos 7 Octa. The T880 is “the highest performance and the most energy-efficient mobile GPU in the Mali family”, with up to 1.8x the performance of the T760 while being 40% more energy-efficient.
Samsung will be taking this new SoC into mass production later this year, and the chip is expected to be featured in the company’s upcoming flagship Galaxy phone.

GlobalFoundries has today officially announced their success with sample 14 nm FinFET production for upcoming AMD products.
(Image credit: KitGuru)
GlobalFoundries licensed 14 nm LPE and LPP technology from Samsung in 2014, and were producing wafers as early as April of this year. At the time a GF company spokesperson was quoted in this report at KitGuru, stating "the early version (14LPE) is qualified in our fab and our lead product is yielding in double digits. Since 2014, we have taped multiple products and testchips and are seeing rapid progress, in yield and maturity, for volume shipments in 2015." Now they have moved past LPE (Low Power Early) to LPP (Low Power Plus), with new products based on the technology slated for 2016:
"AMD has taped out multiple products using GLOBALFOUNDRIES’ 14nm Low Power Plus (14LPP) process technology and is currently conducting validation work on 14LPP production samples. Today’s announcement represents another significant milestone towards reaching full production readiness of GLOBALFOUNDRIES’ 14LPP process technology, which will reach high-volume production in 2016."
GlobalFoundries was originally the manufacturing arm of AMD, and has continued to produce the companies processors since the spin-off in 2012. AMD's current desktop FX-8350 CPU was manufactured on 32 nm SOI, and more recently APUs such as the A10-7850K have been produced at 28 nm - both at GlobalFoundries. Intel's latest offerings such as the flagship 6700K desktop CPU are produced with Intel's 14nm process, and the success of the 14LPP production at GlobalFoundries has the potential to bring AMD's new processors closer parity with Intel (at least from a lithography standpoint).

Tagged: SoC, report, processor, mobile apu, leak, FX-9830PP, cpu, Bristol Ridge, APU, amd
A new report points to an entry from the USB implementors forum, which shows an unreleased AMD Bristol Ridge SoC.
(AMD via VideoCardz.com)
Bristol Ridge itself is not news, as the report at Computer Base observes (translation):
"A leaked roadmap had previously noted that Bristol Ridge is in the coming year soldered on motherboards for notebooks and desktop computers in special BGA package FP4."
(USB.org via Computer Base)
But there is something different about this chip as the report point out the model name FX-9830P pictured in the USB.org screen grab is consistent with the naming scheme for notebook parts, with the highest current model being FX-8800P (Carrizo), a 35W 4-thread Excavator part with 512 stream processors from the R7 GPU core.
(BenchLife via Computer Base)
No details are available other than information from a leaked roadmap (above), which points to Bristol Ridge as an FP4 BGA part for mobile, with a desktop variant for socket FM3 that would replace Kaveri/Godavari (and possibly still an Excavator part). New cores are coming in 2016, and we'll have to wait and see for additional details (or until more information inevitably leaks out).
Update, 11/06/15: WCCFtech expounds on the leak:
“Bristol Ridge isn’t just limited to mobility platforms but will also be featured on AM4 desktop platform as Bristol Ridge will be the APU generation available on desktops in 2016 while Zen would be integrated on the performance focused FX processors.”
WCCFtech’s report also included a link to this SiSoftware database entry for an engineering sample of a dual-core Stoney Ridge processor, a low-power mobile part with a 2.7 GHz clock speed. Stoney Ridge will reportedly succeed Carrizo-L for low-power platforms.
The report also provided this chart to reference the new products:

Tagged: Xeon D, SoC, rumor, report, processor, Pentium D, Intel, cpu
Intel's Xeon D SoC lineup will soon expand to include 12-core and 16-core options, after the platform launched earlier this year with the option of 4 or 8 cores for the 14 nm chips.
The report yesterday from CPU World offers new details on the refreshed lineup which includes both Xeon D and Pentium D SoCs:
"According to our sources, Intel have made some changes to the lineup, which is now comprised of 13 Xeon D and Pentium D SKUs. Even more interesting is that Intel managed to double the maximum number of cores, and consequentially combined cache size, of Xeon D design, and the nearing Xeon D launch may include a few 12-core and 16-core models with 18 MB and 24 MB cache."
The move is not unexpected as Intel initially hinted at an expanded offering by the end of the year (emphasis added):
"...the Intel Xeon processor D-1500 product family is the first offering of a line of processors that will address a broad range of low-power, high-density infrastructure needs. Currently available with 4 or 8 cores and 128 GB of addressable memory..."
Current Xeon D Processors
The new flagship Xeon D model will be the D-1577, a 16-core processor with between 18 and 24 MB of L3 cache (exact specifications are not yet known). These SoCs feature integrated platform controller hub (PCH), I/O, and dual 10 Gigabit Ethernet, and the initial offerings had up to a 45W TDP. It would seem likely that a model with double the core count would either necessitate a higher TDP or simply target a lower clock speed. We should know more before too long.

Tagged: Zen, SoC, processor, imac, APU, apple, amd
Rumor: Apple to Use AMD SoC for Next-Gen iMac News about AMD has been largely depressing of late, with the introduction of the R9 Fury/Fury X and Nano graphics cards a bright spot in the otherwise tumultuous year that was recently capped by a $65 million APU write down. But one area where AMD has managed to earn a big win has been the console market, where their APUs power the latest machines from Microsoft and Sony. The combination of CPU and a powerful GPU on a single chip is ideal for those small form-factor designs, and likewise it would be ideal for a slim all-in-one PC. But an iMac?
Image credit: Apple
A report from WCCFtech today points to the upcoming Zen architecture from AMD as a likely power source for a potential custom SoC:
"A Semi-custom SOC x86 for the iMac would have to include a high performance x86 component, namely Zen, in addition to a graphics engine to drive the visual experience of the device. Such a design would be very similar to the current semi-custom Playstation 4 and XBOX ONE Accelerated Processing Units, combining x86 CPU cores with a highly capable integrated graphics solution."
Those who don't follow Apple probably don't know the company switched over almost exclusively to AMD graphics a short time ago, with NVIDIA solutions phased out of all discrete GPU models. Whether politically motivated or simply the result of AMD providing what Apple wanted from a hardware/driver standpoint I can't say, but it's still a big win for AMD considering Apple's position as one of the largest computer manufacturers - even though its market share is very low in the highly fragmented PC market overall. And while Apple has exclusively used Intel processors in its systems since transitioning away from IBM's PowerPC beginning in 2006, the idea of an AMD custom APU makes a lot of sense for the company, especially for their size and heat constrained iMac designs.
Image credit: WCCFtech
Whether or not you'd ever consider buying an iMac - or any other computer from Apple, for that matter - it's still important for the PC industry as a whole that AMD continues to find success and provide competition for Intel. Consumers can only benefit from the potential for improved performance and reduced cost if competition heats up between Intel and AMD, something we really haven't seen on the CPU front in a few years now. With CEO Lisa Su stating that AMD "had secured two new semi-custom design wins" In their recent earnings call it could very well be that we will see Zen in future iMacs, or in other PC all-in-one solutions for that matter.
Regardless, it will be exciting to see some good competition from AMD, even if we will have to wait quite a while for it. Zen isn't ready yet and we have no indication that any such product would be introduced until later next year. It will be interesting to see what Intel might do to compete given their resources. 2016 could be interesting.

Another player emerges in the CPU landscape: Qualcomm is introducing its first socketed processor for the enterprise market.
Image credit: PC World
A 24-core design based on 64-bit ARM architecture has reached the prototype phase, in a large LGA package resembling an Intel Xeon CPU.
From the report published by PC World:
"Qualcomm demonstrated a pre-production chip in San Francisco on Thursday. It's a purpose-built system-on-chip, different from its Snapdragon processor, that integrates PCIe, storage and other features. The initial version has 24 cores, though the final part will have more, said Anand Chandrasekher, Qualcomm senior vice president."

Qualcomm built servers as proof-of-concept with this new processor, "running a version of Linux, with the KVM hypervisor, streaming HD video to a PC. The chip was running the LAMP stack - Linux, the Apache Web server, MySQL, and PHP - and OpenStack cloud software," according to PC World. The functionality of this design demonstrate the chip's potential to power highly energy-efficient servers, making an obvious statement about the potential cost savings for large data companies such as Google and Facebook.

PC Perspective’s Android to iPhone series explores the opinions, views and experiences of the site’s Editor in Chief, Ryan Shrout, as he moves from the Android smartphone ecosystem to the world of the iPhone and iOS. Having been entrenched in the Android smartphone market for 7+ years, the editorial series is less of a review of the new iPhone 6s as it is an exploration on how the current smartphone market compares to what each sides’ expectations are.
Full Story Listing:
- Day 0: What to Expect
- Day 3: Widgets and Live Photos
- Day 6: Battery Life and Home Screens
- Day 17: SoC Performance
- Day 31: Battery Life and Closing
My iPhone experiment continues, running into the start of the third full week of only carrying and using the new iPhone 6s. Today I am going to focus a bit more on metrics that can be measured in graph form – and that means benchmarks and battery life results. But before I dive into those specifics I need to touch on some other areas.
The most surprising result of this experiment to me, even as I cross into day 17, is that I honestly don’t MISS anything from the previous ecosystem. I theorized at the beginning of this series that I would find applications or use cases that I had adopted with Android that would not be able to be matched on iOS without some significant sacrifices. That isn’t the case – anything that I want to do on the iPhone 6s, I can. Have I needed to find new apps for taking care of my alarms or to monitor my rewards card library? Yes, but the alternatives for iOS are at least as good and often times I find there are more (and often better) solutions. I think it is fair to assume that same feeling of equality would be prevalent for users going in other direction, iPhone to Android, but I can’t be sure without another move back to Android sometime in the future. It may come to that.
My previous alarm app was replaced with Sleep Cycle
In my Day 3 post I mentioned my worry about the lack of Quick Charging support. Well I don’t know why Apple doesn’t talk it up more but the charging rate for the iPhone 6s and iPhone 6s Plus is impressive, and even more so when you pair them with the higher amperage charger that ships with iPads. Though purely non-scientific thus far, my through the day testing showed that I was able to charge the iPhone 6s Plus to 82% (from being dead after a battery test) in the span of 1.5 hours while the OnePlus 2 was only at 35%. I realize the battery on the OnePlus 2 is larger, but based purely on how much use time you get for your charging time wait, the iPhones appear to be just as fast as any Android phone I have used.
Photo taking with the iPhones 6s still impresses me – more so with the speed than the quality. Image quality is fantastic, and we’ll do more analytical testing in the near future, but while attending events over weekend including a Bengals football game (5-0!) and a wedding, the startup process for the camera was snappy and the shutter speed never felt slow. I never thought “Damn, I missed the shot I wanted” and that’s a feeling I’ve had many times over the last several years of phone use.
You don't want to miss photos like this!
There were a couple of annoyances that cropped up, including what I think is a decrease in accuracy of the fingerprint reader on the home button. In the last 4 days I have had more bouncing “try again” notices on the phone than in the entirety of use before that. It’s possible that the button has additional oils from my hands on it or maybe that I am getting lazier about placement of my fingers on the Touch ID, but it’s hard to tell.

Tagged: amd, PRO A12-8800B, Excavator, carrizo pro, Godavari Pro
AMD recently announced a Pro lineup of Excavator based chips which match their Carrizo and Godavari current lineup as far as the specifications go. This was somewhat confusing as there were no real features at first glance that separated the Pro chips from the non-Pro cousins in the press material from AMD or HP. Tech ARP posted the slides from the reveal and they note one key feature that separates the two chip families and why businesses should be interested in them. These are hand-picked dies taken from hand picked wafers which AMD chose as they represent the best of the chips they have fabbed. You should expect performance free from any possible defects which made it past quality control and if you do have bad enough luck to find a way to get a less than perfect chip they come with a 36 month extended OEM warranty.
In addition to being hand picked, machines with an AMD Pro chip will also come with an ARM TrustZone Technology based AMD Secure Processor onboard. If you use a mobile device which has TPM and a crypto-processor onboard you will be familar with the technology; AMD is the first to bring this open sourced security platform to Windows based machines. Small business owners may also be interested the AMD PRO Control Center which is an inventory management client which will not cost as much as ones designed for Enterprise and in theory should be easier to use as well.
This news is of lesser interest to the gamer you never know, if you can secure one of these hand picked chips you may find it gives you a bit more headroom for tweaking than your average run of the mill Godavari or Carrizo would.
"We will now only show you the presentation slides, we also recorded the entire conference call and created a special video presentation based on the conference call for you. We hope you enjoy our work."
